+Authors of XZ Utils
+===================
+
+    XZ Utils is developed and maintained by Lasse Collin
+    <lasse.collin@tukaani.org> and Jia Tan <jiat0218@gmail.com>.
+
+    Major parts of liblzma are based on code written by Igor Pavlov,
+    specifically the LZMA SDK <https://7-zip.org/sdk.html>. Without
+    this code, XZ Utils wouldn't exist.
+
+    The SHA-256 implementation in liblzma is based on the code found from
+    7-Zip <https://7-zip.org/>, which has a modified version of the SHA-256
+    code found from Crypto++ <https://www.cryptopp.com/>. The SHA-256 code
+    in Crypto++ was written by Kevin Springle and Wei Dai.
+
+    Some scripts have been adapted from gzip. The original versions
+    were written by Jean-loup Gailly, Charles Levert, and Paul Eggert.
+    Andrew Dudman helped adapting the scripts and their man pages for
+    XZ Utils.
+
+    The initial version of the threaded .xz decompressor was written
+    by Sebastian Andrzej Siewior.
+
+    The initial version of the .lz (lzip) decoder was written
+    by Michał Górny.
+
+    CLMUL-accelerated CRC code was contributed by Ilya Kurdyukov.
+
+    Other authors:
+      - Jonathan Nieder
+      - Joachim Henke
+
+    The GNU Autotools-based build system contains files from many authors,
+    which I'm not trying to list here.
+
+    Several people have contributed fixes or reported bugs. Most of them
+    are mentioned in the file THANKS.

+#
+# Very limited CMake support for building some parts of XZ Utils
+#
+# For now, this is intended to be useful to build static or shared liblzma
+# on Windows with MSVC (to avoid the need to maintain Visual Studio project
+# files). Building liblzma on a few other platforms should work too but it
+# is somewhat experimental and not as portable as using ./configure.
+#
+# On some platforms this builds also xz and xzdec, but these are
+# highly experimental and meant for testing only:
+#   - No replacement getopt_long(), libc must have it
+#   - No sandboxing support
+#   - No translations
+#
+# Other missing things:
+#   - No xzgrep or other scripts or their symlinks
+#   - No xz tests (liblzma tests only)
+#
+# NOTE: Even if the code compiles without warnings, the end result may be
+# different than via ./configure. Specifically, the list of #defines
+# may be different (if so, probably this CMakeLists.txt got them wrong).
+#
+# This file provides the following installation components (if you only
+# need liblzma, install only its components!):
+#   - liblzma_Runtime
+#   - liblzma_Development
+#   - xz (on some platforms only)
+#   - xzdec (on some platforms only)
+#
+# To find the target liblzma::liblzma from other packages, use the CONFIG
+# option with find_package() to avoid a conflict with the FindLibLZMA module
+# with case-insensitive file systems. For example, to require liblzma 5.2.5
+# or a newer compatible version:
+#
+#     find_package(liblzma 5.2.5 REQUIRED CONFIG)
+#     target_link_libraries(my_application liblzma::liblzma)

+XZ Utils Licensing
+==================
+
+    Different licenses apply to different files in this package. Here
+    is a rough summary of which licenses apply to which parts of this
+    package (but check the individual files to be sure!):
+
+      - liblzma is in the public domain.
+
+      - xz, xzdec, and lzmadec command line tools are in the public
+        domain unless GNU getopt_long had to be compiled and linked
+        in from the lib directory. The getopt_long code is under
+        GNU LGPLv2.1+.
+
+      - The scripts to grep, diff, and view compressed files have been
+        adapted from gzip. These scripts and their documentation are
+        under GNU GPLv2+.
+
+      - All the documentation in the doc directory and most of the
+        XZ Utils specific documentation files in other directories
+        are in the public domain.
+
+        Note: The JavaScript files (under the MIT license) have
+        been removed from the Doxygen-generated HTML version of the
+        liblzma API documentation. Doxygen itself is under the GNU GPL
+        but the remaining files generated by Doxygen are not affected
+        by the licenses used in Doxygen because Doxygen licensing has
+        the following exception:

+            "Documents produced by doxygen are derivative works

+
+      - Translated messages are in the public domain.
+
+      - The build system contains public domain files, and files that
+        are under GNU GPLv2+ or GNU GPLv3+. None of these files end up
+        in the binaries being built.
+
+      - Test files and test code in the tests directory, and debugging
+        utilities in the debug directory are in the public domain.
+
+      - The extra directory may contain public domain files, and files
+        that are under various free software licenses.
+
+    You can do whatever you want with the files that have been put into
+    the public domain. If you find public domain legally problematic,
+    take the previous sentence as a license grant. If you still find
+    the lack of copyright legally problematic, you have too many
+    lawyers.
+
+    As usual, this software is provided "as is", without any warranty.
+
+    If you copy significant amounts of public domain code from XZ Utils
+    into your project, acknowledging this somewhere in your software is
+    polite (especially if it is proprietary, non-free software), but
+    naturally it is not legally required. Here is an example of a good
+    notice to put into "about box" or into documentation:
+
+        This software includes code from XZ Utils <https://tukaani.org/xz/>.
+
+    The following license texts are included in the following files:
+      - COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1
+      - COPYING.GPLv2: GNU General Public License version 2
+      - COPYING.GPLv3: GNU General Public License version 3
+
+    Note that the toolchain (compiler, linker etc.) may add some code
+    pieces that are copyrighted. Thus, it is possible that e.g. liblzma
+    binary wouldn't actually be in the public domain in its entirety
+    even though it contains no copyrighted code from the XZ Utils source
+    package.
+
+    If you have questions, don't hesitate to ask the author(s) for more
+    information.

+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+                  GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+    liblzma: Fix compilation of fastpos_tablegen.c.
+    
+    The macro lzma_attr_visibility_hidden has to be defined to make
+    fastpos.h usable. The visibility attribute is irrelevant to
+    fastpos_tablegen.c so simply #define the macro to an empty value.
+    
+    fastpos_tablegen.c is never built by the included build systems
+    and so the problem wasn't noticed earlier. It's just a standalone
+    program for generating fastpos_table.c.

+
+    liblzma: #define lzma_attr_visibility_hidden in common.h.
+    
+    In ELF shared libs:
+    
+    -fvisibility=hidden affects definitions of symbols but not
+    declarations.[*] This doesn't affect direct calls to functions
+    inside liblzma as a linker can replace a call to lzma_foo@plt
+    with a call directly to lzma_foo when -fvisibility=hidden is used.
+    
+    [*] It has to be like this because otherwise every installed
+        header file would need to explictly set the symbol visibility
+        to default.
+    
+    When accessing extern variables that aren't defined in the
+    same translation unit, compiler assumes that the variable has
+    the default visibility and thus indirection is needed. Unlike
+    function calls, linker cannot optimize this.
+    
+    Using __attribute__((__visibility__("hidden"))) with the extern
+    variable declarations tells the compiler that indirection isn't
+    needed because the definition is in the same shared library.
+    
+    About 15+ years ago, someone told me that it would be good if
+    the CRC tables would be defined in the same translation unit
+    as the C code of the CRC functions. While I understood that it
+    could help a tiny amount, I didn't want to change the code because
+    a separate translation unit for the CRC tables was needed for the
+    x86 assembly code anyway. But when visibility attributes are
+    supported, simply marking the extern declaration with the
+    hidden attribute will get identical result. When there are only
+    a few affected variables, this is trivial to do. I wish I had
+    understood this back then already.

+
+    liblzma: Refer to MinGW-w64 instead of MinGW in the API headers.
+    
+    MinGW (formely a MinGW.org Project, later the MinGW.OSDN Project
+    at <https://osdn.net/projects/mingw/>) has GCC 9.2.0 as the
+    most recent GCC package (released 2021-02-02). The project might
+    still be alive but majority of people have switched to MinGW-w64.
+    Thus it seems clearer to refer to MinGW-w64 in our API headers too.
+    Building with MinGW is likely to still work but I haven't tested it
+    in the recent years.

+    CMake: Use -D_FILE_OFFSET_BITS=64 if (and only if) needed.
+    
+    A CMake option LARGE_FILE_SUPPORT is created if and only if
+    -D_FILE_OFFSET_BITS=64 affects sizeof(off_t).
+    
+    This is needed on many 32-bit platforms and even with 64-bit builds
+    with MinGW-w64 to get support for files larger than 2 GiB.

+    CMake: Fix Windows build with Clang/LLVM 17.
+    
+    llvm-windres 17.0.0 has more accurate emulation of GNU windres, so
+    the hack for GNU windres must now be used with llvm-windres too.
+    
+    LLVM 16.0.6 has the old behavior and there likely won't be more
+    16.x releases. So we can simply check for >= 17.0.0.
+    
+    The workaround must not be used with Clang that is acting in
+    MSVC mode. This checks for the known environments that need
+    the workaround instead of using "NOT MSVC".

+
+    Build: Silence Autoconf warning.
+    
+    There was a use of AC_COMPILE_IFELSE that didn't use
+    AC_LANG_SOURCE and Autoconf warned about this. The omission
+    had been intentional but it turned out that this didn't do
+    what I thought it would.
+    
+    Autoconf 2.71 manual gives an impression that AC_LANG_SOURCE
+    inserts all #defines that have been made with AC_DEFINE so
+    far (confdefs.h). The idea was that omitting AC_LANG_SOURCE
+    would mean that only the exact code included in the
+    AC_COMPILE_IFELSE call would be compiled.
+    
+    With C programs this is not true: the #defines get added without
+    AC_LANG_SOURCE too. There seems to be no neat way to avoid this.
+    Thus, with the C language at least, adding AC_LANG_SOURCE makes
+    no other difference than silencing a warning from Autoconf. The
+    generated "configure" remains identical. (Docs of AC_LANG_CONFTEST
+    say that the #defines have been inserted since Autoconf 2.63b and
+    that AC_COMPILE_IFELSE uses AC_LANG_CONFTEST. So the behavior is
+    documented if one also reads the docs of macros that one isn't
+    calling directly.)
+    
+    Any extra code, including #defines, can cause problems for
+    these two tests because these tests must use -Werror.
+    CC=clang CFLAGS=-Weverything is the most extreme example.
+    It enables -Wreserved-macro-identifier which warns about
+    It's possible to write a test file that passes -Weverything but
+    it becomes impossible when Autoconf inserts confdefs.h.
+    
+    So this commit adds AC_LANG_SOURCE to silence Autoconf warnings.
+    A different solution is needed for -Werror tests.

+    xz: Windows: Don't (de)compress to special files like "con" or "nul".
+    
+    Before this commit, the following writes "foo" to the
+    console and deletes the input file:
+    
+        echo foo | xz > con_xz
+        xz --suffix=_xz --decompress con_xz
+    
+    It cannot happen without --suffix because names like con.xz
+    are also special and so attempting to decompress con.xz
+    (or compress con to con.xz) will already fail when opening
+    the input file.
+    
+    Similar thing is possible when compressing. The following
+    writes to "nul" and the input file "n" is deleted.
+    
+        echo foo | xz > n
+        xz --suffix=ul n
+    
+    Now xz checks if the destination is a special file before
+    continuing. DOS/DJGPP version had a check for this but
+    Windows (and OS/2) didn't.

+    liblzma: Update assert in vli_ceil4().
+    
+    The argument to vli_ceil4() should always guarantee the return value
+    is also a valid lzma_vli. Thus the highest three valid lzma_vli values
+    are invalid arguments. All uses of the function ensure this so the
+    assert is updated to match this.

+
+    liblzma: Add overflow check for Unpadded size in lzma_index_append().
+    
+    This was not a security bug since there was no path to overflow
+    UINT64_MAX in lzma_index_append() or when it calls index_file_size().
+    The bug was discovered by a failing assert() in vli_ceil4() when called
+    from index_file_size() when unpadded_sum (the sum of the compressed size
+    of current Stream and the unpadded_size parameter) exceeds LZMA_VLI_MAX.
+    
+    Previously, the unpadded_size parameter was checked to be not greater
+    than UNPADDED_SIZE_MAX, but no check was done once compressed_base was
+    added.
+    
+    This could not have caused an integer overflow in index_file_size() when
+    called by lzma_index_append(). The calculation for file_size breaks down
+    into the sum of:
+    
+    - Compressed base from all previous Streams
+    - 2 * LZMA_STREAM_HEADER_SIZE (size of the current Streams header and
+      footer)
+    - stream_padding (can be set by lzma_index_stream_padding())
+    - Compressed base from the current Stream
+    - Unpadded size (parameter to lzma_index_append())
+    
+    The sum of everything except for Unpadded size must be less than
+    LZMA_VLI_MAX. This is guarenteed by overflow checks in the functions
+    that can set these values including lzma_index_stream_padding(),
+    lzma_index_append(), and lzma_index_cat(). The maximum value for
+    Unpadded size is enforced by lzma_index_append() to be less than or
+    equal UNPADDED_SIZE_MAX. Thus, the sum cannot exceed UINT64_MAX since
+    LZMA_VLI_MAX is half of UINT64_MAX.
+    
+    Thanks to Joona Kannisto for reporting this.

+    Build: Conditionally allow win95 threads and --enable-small.
+    
+    When the compiler supports __attribute__((__constructor__))
+    mythread_once() is never used, even with --enable-small. A configuration
+    with win95 threads and --enable-small will compile and be thread safe so
+    it can be allowed.
+    
+    This isn't a very common configuration since MSVC does not support

+    for MSYS2 can use win95 threads and have
+    __attribute__((__constructor__)) support.

+    CMake: Conditionally allow the creation of broken symlinks.
+    
+    The CMake build will try to create broken symlinks on Unix and Unix-like
+    platforms. Cygwin and MSYS2 are Unix-like, but may not be able to create
+    broken symlinks. The value of the CYGWIN or MSYS environment variables
+    determine if broken symlinks are valid.
+    
+    The default for MSYS2 does not allow for broken symlinks, so the CMake
+    build has been broken for MSYS2 since commit
+    80a1a8bb838842a2be343bd88ad1462c21c5e2c9.

+    
+    In lzma_memcmplen(), the <intrin.h> header file is only included if

+    previously used if _M_X64 was defined. GCC for MSYS2 defines _M_X64 but
+    not _MSC_VER so _BitScanForward64() was used without including
+    <intrin.h>.
+    
+    Now, lzma_memcmplen() will use __builtin_ctzll() for MSYS2 GCC builds as

+    Tests: Improve feature testing for skipping.
+    
+    Fixed a bug where test_compress_* would all fail if arm64 or armthumb
+    filters were enabled for compression but arm was disabled. Since the
+    grep tests only checked for "define HAVE_ENCODER_ARM", this would match
+    on HAVE_ENCODER_ARM64 or HAVE_ENCODER_ARMTHUMB.
+    
+    Now the config.h feature test requires " 1" at the end to prevent the
+    prefix problem. have_feature() was also updated for this even though
+    there were known current bugs affecting it. This is just in case future
+    features have a similar prefix problem.

+    liblzma: Prevent uninitialzed warning in mt stream encoder.
+    
+    This change only impacts the compiler warning since it was impossible
+    for the wait_abs struct in stream_encode_mt() to be used before it was
+    initialized since mythread_condtime_set() will always be called before
+    mythread_cond_timedwait().
+    
+    Since the mythread.h code is different between the POSIX and
+    Windows versions, this warning was only present on Windows builds.
+    
+    Thanks to Arthur S for reporting the warning and providing an initial
+    patch.

+    CMake: Protects against double find_package
+    
+    Boost iostream uses `find_package` in quiet mode and then again uses
+    `find_package` with required. This second call triggers a
+    `add_library cannot create imported target "LibLZMA::LibLZMA"
+    because another target with the same name already exists.`
+    
+    This can simply be fixed by skipping the alias part on secondary

+    Wrong line was changed in 7062348bf35c1e4cbfee00ad9fffb4a21aa6eff7.
+    Also, this has >= instead of == since ints larger than 32 bits would

+    Windows: Include <intrin.h> when needed.
+    
+    Legacy Windows did not need to #include <intrin.h> to use the MSVC
+    intrinsics. Newer versions likely just issue a warning, but the MSVC
+    documentation says to include the header file for the intrinsics we use.
+    
+    GCC and Clang can "pretend" to be MSVC on Windows, so extra checks are
+    needed in tuklib_integer.h to only include <intrin.h> when it will is
+    actually needed.

+    tuklib_integer: Use __builtin_clz() with Clang.
+    
+    Clang has support for __builtin_clz(), but previously Clang would
+    fallback to either the MSVC intrinsic or the regular C code. This was
+    discovered due to a bug where a new version of Clang required the
+    <intrin.h> header file in order to use the MSVC intrinsics.
+    
+    Thanks to Anton Kochkov for notifying us about the bug.

+    The thread method is now configurable for the CMake build. It matches

+    OFF (no threading), posix, win95, and vista. If both Windows and

+    target_link_libraries(liblzma Threads::Threads)
+    
+    since on systems like MinGW-w64 it would link the posix threads

+
+    Build: Fix --disable-threads breaking the building of shared libs.
+    
+    This is broken in the releases 5.2.6 to 5.4.2. A workaround
+    for these releases is to pass EGREP='grep -E' as an argument
+    to configure in addition to --disable-threads.
+    
+    The problem appeared when m4/ax_pthread.m4 was updated in
+    the commit 6629ed929cc7d45a11e385f357ab58ec15e7e4ad which
+    introduced the use of AC_EGREP_CPP. AC_EGREP_CPP calls
+    AC_REQUIRE([AC_PROG_EGREP]) to set the shell variable EGREP
+    but this was only executed if POSIX threads were enabled.
+    Libtool code also has AC_REQUIRE([AC_PROG_EGREP]) but Autoconf
+    omits it as AC_PROG_EGREP has already been required earlier.
+    Thus, if not using POSIX threads, the shell variable EGREP
+    would be undefined in the Libtool code in configure.
+    
+    ax_pthread.m4 is fine. The bug was in configure.ac which called
+    AX_PTHREAD conditionally in an incorrect way. Using AS_CASE
+    ensures that all AC_REQUIREs get always run.
+    
+    Thanks to Frank Busse for reporting the bug.

+    liblzma: Add set lzma.h as the main page for Doxygen documentation.
+    
+    The \mainpage command is used in the first block of comments in lzma.h.
+    This changes the previously nearly empty index.html to use the first
+    comment block in lzma.h for its contents.
+    
+    lzma.h is no longer documented separately, but this is for the better
+    since lzma.h only defined a few macros that users do not need to use.
+    The individual API header files all have a disclaimer that they should
+    not be #included directly, so there should be no confusion on the fact
+    that lzma.h should be the only header used by applications.
+    
+    Additionally, the note "See ../lzma.h for information about liblzma as
+    a whole." was removed since lzma.h is now the main page of the
+    generated HTML and does not have its own page anymore. So it would be
+    confusing in the HTML version and was only a "nice to have" when
+    browsing the source files.

+
+    Build: Create doxygen/update-doxygen script.
+    
+    This is a helper script to generate the Doxygen documentation. It can be
+    run in 'liblzma' or 'internal' mode by setting the first argument. It
+    will default to 'liblzma' mode and only generate documentation for the
+    liblzma API header files.
+    
+    The helper script will be run during the custom mydist hook when we
+    create releases. This hook already alters the source directory, so its
+    fine to do it here too. This way, we can include the Doxygen generated
+    files in the distrubtion and when installing.
+    
+    In 'liblzma' mode, the JavaScript is stripped from the .html files and
+    the .js files are removed. This avoids license hassle from jQuery and
+    other libraries that Doxygen 1.9.6 puts into jquery.js in minified form.

+    Doxygen: Refactor Doxyfile.in to doxygen/Doxyfile.
+    
+    Instead of having Doxyfile.in configured by Autoconf, the Doxyfile
+    can have the tags that need to be configured piped into the doxygen

+    
+    Going forward, the documentation should be generated in two different

+    
+    liblzma is useful for most users. It is the documentation for just

+    
+    internal is for people who want to understand how xz and liblzma work.

+    xz: Don't fail if Capsicum is enabled but kernel doesn't support it.
+    
+    (This commit combines related commits from the master branch.)
+    
+    If Capsicum support is missing from the kernel or xz is being run
+    in an emulator that lacks Capsicum suport, the syscalls will fail
+    and set errno to ENOSYS. Previously xz would display and error and
+    exit, making xz unusable. Now it will check for ENOSYS and run
+    without sandbox support. Other tools like ssh behave similarly.
+    
+    Displaying a warning for missing Capsicum support was considered
+    but such extra output would quickly become annoying. It would also
+    break test_scripts.sh in "make check".
+    
+    Also move cap_enter() to be the first step instead of the last one.
+    This matches the example in the cap_rights_limit(2) man page. With
+    the current code it shouldn't make any practical difference though.
+

+    The documentation was updated to reflect this complexity, since this

+
+    liblzma: Avoid null pointer + 0 (undefined behavior in C).
+    
+    In the C99 and C17 standards, section 6.5.6 paragraph 8 means that
+    adding 0 to a null pointer is undefined behavior. As of writing,
+    "clang -fsanitize=undefined" (Clang 15) diagnoses this. However,
+    I'm not aware of any compiler that would take advantage of this
+    when optimizing (Clang 15 included). It's good to avoid this anyway
+    since compilers might some day infer that pointer arithmetic implies
+    that the pointer is not NULL. That is, the following foo() would then
+    unconditionally return 0, even for foo(NULL, 0):
+    
+        void bar(char *a, char *b);
+    
+        int foo(char *a, size_t n)
+        {
+            bar(a, a + n);
+            return a == NULL;
+        }
+    
+    In contrast to C, C++ explicitly allows null pointer + 0. So if
+    the above is compiled as C++ then there is no undefined behavior
+    in the foo(NULL, 0) call.
+    
+    To me it seems that changing the C standard would be the sane
+    thing to do (just add one sentence) as it would ensure that a huge
+    amount of old code won't break in the future. Based on web searches
+    it seems that a large number of codebases (where null pointer + 0
+    occurs) are being fixed instead to be future-proof in case compilers
+    will some day optimize based on it (like making the above foo(NULL, 0)
+    return 0) which in the worst case will cause security bugs.
+    
+    Some projects don't plan to change it. For example, gnulib and thus
+    many GNU tools currently require that null pointer + 0 is defined:
+    
+        https://lists.gnu.org/archive/html/bug-gnulib/2021-11/msg00000.html
+    
+        https://www.gnu.org/software/gnulib/manual/html_node/Other-portability-assumptions.html
+    
+    In XZ Utils null pointer + 0 issue should be fixed after this
+    commit. This adds a few if-statements and thus branches to avoid
+    null pointer + 0. These check for size > 0 instead of ptr != NULL
+    because this way bugs where size > 0 && ptr == NULL will likely
+    get caught quickly. None of them are in hot spots so it shouldn't
+    matter for performance.
+    
+    A little less readable version would be replacing
+    
+        ptr + offset
+    
+    with
+    
+        offset != 0 ? ptr + offset : ptr
+    
+    or creating a macro for it:
+    
+        #define my_ptr_add(ptr, offset) \
+                ((offset) != 0 ? ((ptr) + (offset)) : (ptr))
+    
+    Checking for offset != 0 instead of ptr != NULL allows GCC >= 8.1,
+    Clang >= 7, and Clang-based ICX to optimize it to the very same code
+    as ptr + offset. That is, it won't create a branch. So for hot code
+    this could be a good solution to avoid null pointer + 0. Unfortunately
+    other compilers like ICC 2021 or MSVC 19.33 (VS2022) will create a
+    branch from my_ptr_add().
+    
+    Thanks to Marcin Kowalczyk for reporting the problem:

+
+    Build: Use only the generic symbol versioning on MicroBlaze.
+    
+    On MicroBlaze, GCC 12 is broken in sense that
+    __has_attribute(__symver__) returns true but it still doesn't
+    support the __symver__ attribute even though the platform is ELF
+    and symbol versioning is supported if using the traditional
+    __asm__(".symver ...") method. Avoiding the traditional method is
+    good because it breaks LTO (-flto) builds with GCC.
+    
+    See also: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101766
+    
+    For now the only extra symbols in liblzma_linux.map are the
+    compatibility symbols with the patch that spread from RHEL/CentOS 7.
+    These require the use of __symver__ attribute or __asm__(".symver ...")
+    in the C code. Compatibility with the patch from CentOS 7 doesn't
+    seem valuable on MicroBlaze so use liblzma_generic.map on MicroBlaze
+    instead. It doesn't require anything special in the C code and thus
+    no LTO issues either.
+    
+    An alternative would be to detect support for __symver__
+    attribute in configure.ac and CMakeLists.txt and fall back
+    to __asm__(".symver ...") but then LTO would be silently broken
+    on MicroBlaze. It sounds likely that MicroBlaze is a special
+    case so let's treat it as a such because that is simpler. If
+    a similar issue exists on some other platform too then hopefully
+    someone will report it and this can be reconsidered.
+    
+    (This doesn't do the same fix in CMakeLists.txt. Perhaps it should
+    but perhaps CMake build of liblzma doesn't matter much on MicroBlaze.
+    The problem breaks the build so it's easy to notice and can be fixed
+    later.)
+    
+    Thanks to Vincent Fazio for reporting the problem and proposing
+    a patch (in the end that solution wasn't used):

+    liblzma: Very minor API doc tweaks.
+    
+    Use "member" to refer to struct members as that's the term used
+    by the C standard.
+    
+    Use lzma_options_delta.dist and such in docs so that in Doxygen's
+    HTML output they will link to the doc of the struct member.
+    
+    Clean up a few trailing white spaces too.

+    tuklib_physmem: Silence warning from -Wcast-function-type on MinGW-w64.
+    
+    tuklib_physmem depends on GetProcAddress() for both MSVC and MinGW-w64
+    to retrieve a function address. The proper way to do this is to cast the
+    return value to the type of function pointer retrieved. Unfortunately,
+    this causes a cast-function-type warning, so the best solution is to
+    simply ignore the warning.

+
+    Build: Omit -Wmissing-noreturn from the default warnings.
+    
+    It's not that important. It can be annoying in builds that
+    disable many features since in those cases the tests programs
+    will correctly trigger this warning with Clang.

+    xz: Use ssize_t for the to-be-ignored return value from write(fd, ptr, 1).
+    
+    It makes no difference here as the return value fits into an int

+    
+    It doesn't warn on a 64-bit system because truncating
+    a ptrdiff_t (signed long) to uint32_t is diagnosed under
+    -Wconversion by GCC and -Wshorten-64-to-32 by Clang.

+
+    Tests: Fix warnings from clang --Wassign-enum.
+    
+    Explicitly casting the integer to lzma_check silences the warning.
+    Since such an invalid value is needed in multiple tests, a constant
+    INVALID_LZMA_CHECK_ID was added to tests.h.
+    
+    The use of 0x1000 for lzma_block.check wasn't optimal as if
+    the underlying type is a char then 0x1000 will be truncated to 0.
+    However, in these test cases the value is ignored, thus even with
+    such truncation the test would have passed.

+
+    Tests: Silence warnings from -Wsign-conversion.
+    
+    Note that assigning an unsigned int to lzma_check doesn't warn
+    on GNU/Linux x86-64 since the enum type is unsigned on that
+    platform. The enum can be signed on some other platform though
+    so it's best to use enumeration type lzma_check in these situations.

+    xz: Include <strings.h> in suffix.c if needed for strcasecmp().
+    
+    SUSv2 and POSIX.1‐2017 declare only a few functions in <strings.h>.
+    Of these, strcasecmp() is used on some platforms in suffix.c.
+    Nothing else in the project needs <strings.h> (at least if
+    building on a modern system).
+    
+    sysdefs.h currently includes <strings.h> if HAVE_STRINGS_H is
+    defined and suffix.c relied on this.
+    
+    Note that dos/config.h doesn't #define HAVE_STRINGS_H even though
+    DJGPP does have strings.h. It isn't needed with DJGPP as strcasecmp()
+    is also in <string.h> in DJGPP.

+    liblzma: CLMUL CRC64: Work around a bug in MSVC, second attempt.
+    
+    This affects only 32-bit x86 builds. x86-64 is OK as is.
+    
+    I still cannot easily test this myself. The reporter has tested
+    this and it passes the tests included in the CMake build and
+    performance is good: raw CRC64 is 2-3 times faster than the
+    C version of the slice-by-four method. (Note that liblzma doesn't
+    include a MSVC-compatible version of the 32-bit x86 assembly code
+    for the slice-by-four method.)
+    
+    Thanks to Iouri Kharon for figuring out a fix, testing, and
+    benchmarking.

+
+    Tests: test_filter_flags: Clean up minor issues.
+    
+    Here are the list of the most significant issues addressed:
+    - Avoid using internal common.h header. It's not good to copy the
+    constants like this but common.h cannot be included for use outside
+    of liblzma. This is the quickest thing to do that could be fixed later.
+    
+    - Omit the INIT_FILTER macro. Initialization should be done with just
+    regular designated initializers.
+    
+    - Use start_offset = 257 for BCJ tests. It demonstrates that Filter
+    Flags encoder and decoder don't validate the options thoroughly.
+    257 is valid only for the x86 filter. This is a bit silly but
+    not a significant problem in practice because the encoder and
+    decoder initialization functions will catch bad alignment still.
+    Perhaps this should be fixed but it's not urgent and doesn't need
+    to be in 5.4.x.
+    
+    - Various tweaks to comments such as filter id -> Filter ID

+    liblzma: CLMUL CRC64: Workaround a bug in MSVC (VS2015-2022).
+    
+    I haven't tested with MSVC myself and there doesn't seem to be
+    information about the problem online, so I'm relying on the bug report.
+    
+    Thanks to Iouri Kharon for the bug report and the patch.

+
+    Build: Require that _mm_set_epi64x() is usable to enable CLMUL support.
+    
+    VS2013 doesn't have _mm_set_epi64x() so this way CLMUL gets
+    disabled with VS2013.
+    
+    Thanks to Iouri Kharon for the bug report.

+    liblzma: Remove common.h include from common/index.h.
+    
+    common/index.h is needed by liblzma internally and tests. common.h will
+    include and define many things that are not needed by the tests.
+    
+    Also, this prevents include order problems because both common.h and
+    lzma.h define LZMA_API. On most platforms it results only in a warning
+    but on Windows it would break the build as the definition in common.h
+    must be used only for building liblzma itself.

+    Previously, if threading was enabled HAVE_DECL_CLOCK_MONOTONIC would always

+    xz: Don't modify argv[].
+    
+    The code that parses --memlimit options and --block-list modified
+    the argv[] when parsing the option string from optarg. This was
+    visible in "ps auxf" and such and could be confusing. I didn't
+    understand it back in the day when I wrote that code. Now a copy
+    is allocated when modifiable strings are needed.

+    liblzma: Omit zero-skipping from ARM64 filter.
+    
+    It has some complicated downsides and its usefulness is more limited
+    than I originally thought. So this change is bad for certain very
+    specific situations but a generic solution that works for other
+    filters (and is otherwise better too) is planned anyway. And this
+    way 7-Zip can use the same compatible filter for the .7z format.
+    
+    This is still marked as experimental with a new temporary Filter ID.

+    
+    lzma_str_to_filters() uses static error messages which makes

+    where an error occurred though which helps quite a bit if
+    applications take advantage of it. Dynamic error messages can
+    be added later with a new flag if it seems important enough.

+Date:   2022-11-27 23:16:21 +0200
+
+    liblzma: Add LZMA_FILTER_LZMA1EXT to support LZMA1 without end marker.
+    
+    Some file formats need support for LZMA1 streams that don't use
+    the end of payload marker (EOPM) alias end of stream (EOS) marker.
+    So far liblzma API has supported decompressing such streams via
+    lzma_alone_decoder() when .lzma header specifies a known
+    uncompressed size. Encoding support hasn't been available in the API.
+    
+    Instead of adding a new LZMA1-only API for this purpose, this commit
+    adds a new filter ID for use with raw encoder and decoder. The main
+    benefit of this approach is that then also filter chains are possible,
+    for example, if someone wants to implement support for .7z files that
+    use the x86 BCJ filter with LZMA1 (not BCJ2 as that isn't supported
+    in liblzma).

+    Build: Don't put GNU/Linux-specific symbol versions into static liblzma.
+    
+    It not only makes no sense to put symbol versions into a static library
+    but it can also cause breakage.
+    
+    By default Libtool #defines PIC if building a shared library and
+    doesn't define it for static libraries. This is documented in the
+    Libtool manual. It can be overriden using --with-pic or --without-pic.
+    configure.ac detects if --with-pic or --without-pic is used and then
+    gives an error if neither --disable-shared nor --disable-static was
+    used at the same time. Thus, in normal situations it works to build
+    both shared and static library at the same time on GNU/Linux,
+    only --with-pic or --without-pic requires that only one type of
+    library is built.
+    
+    Thanks to John Paul Adrian Glaubitz from Debian for reporting
+    the problem that occurred on ia64:

+
+    liblzma: Refactor to use lzma_filters_free().
+    
+    lzma_filters_free() sets the options to NULL and ids to
+    LZMA_VLI_UNKNOWN so there is no need to do it by caller;
+    the filter arrays will always be left in a safe state.
+    
+    Also use memcpy() instead of a loop to copy a filter chain
+    when it is known to be safe to copy LZMA_FILTERS_MAX + 1
+    (even if the elements past the terminator might be uninitialized).

+    liblzma: Fix another invalid free() after memory allocation failure.
+    
+    This time it can happen when lzma_stream_encoder_mt() is used
+    to reinitialize an existing multi-threaded Stream encoder
+    and one of 1-4 tiny allocations in lzma_filters_copy() fail.

+    It's very similar to the previous bug

+    
+    The documentation mentions that lzma_block_encoder() supports

+
+    liblzma: Fix invalid free() after memory allocation failure.
+    
+    The bug was in the single-threaded .xz Stream encoder
+    in the code that is used for both re-initialization and for
+    lzma_filters_update(). To trigger it, an application had
+    to either re-initialize an existing encoder instance with
+    lzma_stream_encoder() or use lzma_filters_update(), and
+    then one of the 1-4 tiny allocations in lzma_filters_copy()
+    (called from stream_encoder_update()) must fail. An error
+    was correctly reported but the encoder state was corrupted.
+    
+    This is related to the recent fix in
+    f8ee61e74eb40600445fdb601c374d582e1e9c8a which is good but
+    it wasn't enough to fix the main problem in stream_encoder.c.

+
+    liblzma: Add fast CRC64 for 32/64-bit x86 using SSSE3 + SSE4.1 + CLMUL.
+    
+    It also works on E2K as it supports these intrinsics.
+    
+    On x86-64 runtime detection is used so the code keeps working on
+    older processors too. A CLMUL-only build can be done by using
+    -msse4.1 -mpclmul in CFLAGS and this will reduce the library
+    size since the generic implementation and its 8 KiB lookup table
+    will be omitted.
+    
+    On 32-bit x86 this isn't used by default for now because by default
+    on 32-bit x86 the separate assembly file crc64_x86.S is used.
+    If --disable-assembler is used then this new CLMUL code is used
+    the same way as on 64-bit x86. However, a CLMUL-only build
+    (-msse4.1 -mpclmul) won't omit the 8 KiB lookup table on
+    32-bit x86 due to a currently-missing check for disabled
+    assembler usage.
+    
+    The configure.ac check should be such that the code won't be
+    built if something in the toolchain doesn't support it but
+    --disable-clmul-crc option can be used to unconditionally
+    disable this feature.
+    
+    CLMUL speeds up decompression of files that have compressed very
+    well (assuming CRC64 is used as a check type). It is know that
+    the CLMUL code is significantly slower than the generic code for
+    tiny inputs (especially 1-8 bytes but up to 16 bytes). If that
+    is a real-world problem then there is already a commented-out
+    variant that uses the generic version for small inputs.
+    
+    Thanks to Ilya Kurdyukov for the original patch which was
+    derived from a white paper from Intel [1] (published in 2009)
+    and public domain code from [2] (released in 2016).

+    Build: Omit x86_64 from --enable-assembler.
+    
+    It didn't do anything. There are only 32-bit x86 assembly files
+    and it feels likely that new files won't be added as intrinsics
+    in C are more portable across toolchains and OSes.

+    
+    __SSE2__ is the correct macro for SSE2 support with GCC, Clang,
+    and ICC. __SSE2_MATH__ means doing floating point math with SSE2
+    instead of 387. Often the latter macro is defined if the first
+    one is but it was still a bug.

+
+    xz: Add --arm64 to --long-help and omit endianness from ARM(-Thumb).
+    
+    Modern 32-bit ARM in big endian mode use little endian for
+    instruction encoding still, so the filters work on such
+    executables too. It's likely less confusing for users this way.
+    
+    The --arm64 option hasn't been implemented yet (there is
+    --experimental-arm64 but it's different). The --arm64 option
+    is added now anyway because this is the likely result and the
+    strings need to be ready for translators.
+    
+    Thanks to Jia Tan.

+
+    liblzma: Add .lz (lzip) decompression support (format versions 0 and 1).
+    
+    Support for format version 0 was removed from lzip 1.18 for some
+    reason. .lz format version 0 files are rare (and old) but some
+    source packages were released in this format, and some people might
+    have personal files in this format too. It's very little extra code
+    to support it along side format version 1 so this commits adds
+    support for both.
+    
+    The Sync Flush marker extentension to the original .lz format
+    version 1 isn't supported. It would require changes to the
+    LZMA decoder itself. Such files are very rare anyway.
+    
+    See the API doc for lzma_lzip_decoder() for more details about
+    the .lz format support.
+    
+    Thanks to Michał Górny for the original patch.

+

+    liblzma: Include cached memory in reported memusage in threaded decoder.
+    
+    This affects lzma_memusage() and lzma_memlimit_set() when used
+    with the threaded decompressor. Now all allocations are reported
+    by lzma_memusage() (so it's not misleading) and lzma_memlimit_set()
+    cannot lower the limit below that value.
+    
+    The alternative would have been to allow lowering the limit if
+    doing so is possible by freeing the cached memory but since
+    the primary use case of lzma_memlimit_set() is to increase
+    memlimit after LZMA_MEMLIMIT_ERROR this simple approach
+    was selected.
+    
+    The cached memory was always included when enforcing
+    the memory usage limit while decoding.
+    
+    Thanks to Jia Tan.

+
+    xz: Fix decompressor behavior if input uses an unsupported check type.
+    
+    Now files with unsupported check will make xz display
+    a warning, set the exit status to 2 (unless --no-warn is used),
+    and then decompress the file normally. This is how it was
+    supposed to work since the beginning but this was broken by
+    the commit 231c3c7098f1099a56abb8afece76fc9b8699f05, that is,
+    a little before 5.0.0 was released. The buggy behavior displayed
+    a message, set exit status 1 (error), and xz didn't attempt to
+    to decompress the file.
+    
+    This doesn't matter today except for special builds that disable
+    CRC64 or SHA-256 at build time (but such builds should be used
+    in special situations only). The bug matters if new check type
+    is added in the future and an old xz version is used to decompress
+    such a file; however, it's likely that such files would use a new
+    filter too and an old xz wouldn't be able to decompress the file
+    anyway.
+    
+    The first hunk in the commit is the actual fix. The second hunk
+    is a cleanup since LZMA_TELL_ANY_CHECK isn't used in xz.
+    
+    There is a test file for unsupported check type but it wasn't
+    used by test_files.sh, perhaps due to different behavior between
+    xz and the simpler xzdec.

+    Tests: Skip tests in test_*.sh if encoders and/or decoders are disabled.
+    
+    This isn't perfect as the scripts can still fail if only

+
+    liblzma: Fix copying of check type statistics in lzma_index_cat().
+    
+    The check type of the last Stream in dest was never copied to
+    dest->checks (the code tried to copy it but it was done too late).
+    This meant that the value returned by lzma_index_checks() would
+    only include the check type of the last Stream when multiple
+    lzma_indexes had been concatenated.
+    
+    In xz --list this meant that the summary would only list the
+    check type of the last Stream, so in this sense this was only
+    a visual bug. However, it's possible that some applications
+    use this information for purposes other than merely showing
+    it to the users in an informational message. I'm not aware of
+    such applications though and it's quite possible that such
+    applications don't exist.
+    
+    Regular streamed decompression in xz or any other application
+    doesn't use lzma_index_cat() and so this bug cannot affect them.

+    liblzma: lzma_filters_copy: Keep dest[] unmodified if an error occurs.
+    
+    lzma_stream_encoder() and lzma_stream_encoder_mt() always assumed
+    this. Before this patch, failing lzma_filters_copy() could result
+    in free(invalid_pointer) or invalid memory reads in stream_encoder.c
+    or stream_encoder_mt.c.
+    
+    To trigger this, allocating memory for a filter options structure
+    has to fail. These are tiny allocations so in practice they very
+    rarely fail.
+    
+    Certain badness in the filter chain array could also make
+    lzma_filters_copy() fail but both stream_encoder.c and
+    stream_encoder_mt.c validate the filter chain before
+    trying to copy it, so the crash cannot occur this way.

+    The documentation in src/liblzma/api/lzma/index.h suggests that

+    are checked for overflow, but only the unpadded size was checked.

+    liblzma: Vaccinate against an ill patch from RHEL/CentOS 7.
+    
+    RHEL/CentOS 7 shipped with 5.1.2alpha, including the threaded
+    encoder that is behind #ifdef LZMA_UNSTABLE in the API headers.
+    In 5.1.2alpha these symbols are under XZ_5.1.2alpha in liblzma.map.
+    API/ABI compatibility tracking isn't done between development
+    releases so newer releases didn't have XZ_5.1.2alpha anymore.
+    
+    Later RHEL/CentOS 7 updated xz to 5.2.2 but they wanted to keep
+    the exported symbols compatible with 5.1.2alpha. After checking
+    the ABI changes it turned out that >= 5.2.0 ABI is backward
+    compatible with the threaded encoder functions from 5.1.2alpha
+    (but not vice versa as fixes and extensions to these functions
+    were made between 5.1.2alpha and 5.2.0).
+    
+    In RHEL/CentOS 7, XZ Utils 5.2.2 was patched with
+    xz-5.2.2-compat-libs.patch to modify liblzma.map:
+    
+      - XZ_5.1.2alpha was added with lzma_stream_encoder_mt and
+        lzma_stream_encoder_mt_memusage. This matched XZ Utils 5.1.2alpha.
+    
+      - XZ_5.2 was replaced with XZ_5.2.2. It is clear that this was
+        an error; the intention was to keep using XZ_5.2 (XZ_5.2.2
+        has never been used in XZ Utils). So XZ_5.2.2 lists all
+        symbols that were listed under XZ_5.2 before the patch.
+        lzma_stream_encoder_mt and _mt_memusage are included too so
+        they are listed both here and under XZ_5.1.2alpha.
+    
+    The patch didn't add any __asm__(".symver ...") lines to the .c
+    files. Thus the resulting liblzma.so exports the threaded encoder
+    functions under XZ_5.1.2alpha only. Listing the two functions
+    also under XZ_5.2.2 in liblzma.map has no effect without
+    matching .symver lines.
+    
+    The lack of XZ_5.2 in RHEL/CentOS 7 means that binaries linked
+    against unpatched XZ Utils 5.2.x won't run on RHEL/CentOS 7.
+    This is unfortunate but this alone isn't too bad as the problem
+    is contained within RHEL/CentOS 7 and doesn't affect users
+    of other distributions. It could also be fixed internally in
+    RHEL/CentOS 7.
+    
+    The second problem is more serious: In XZ Utils 5.2.2 the API
+    headers don't have #ifdef LZMA_UNSTABLE for obvious reasons.
+    This is true in RHEL/CentOS 7 version too. Thus now programs
+    using new APIs can be compiled without an extra #define. However,
+    the programs end up depending on symbol version XZ_5.1.2alpha
+    (and possibly also XZ_5.2.2) instead of XZ_5.2 as they would
+    with an unpatched XZ Utils 5.2.2. This means that such binaries
+    won't run on other distributions shipping XZ Utils >= 5.2.0 as
+    they don't provide XZ_5.1.2alpha or XZ_5.2.2; they only provide
+    XZ_5.2 (and XZ_5.0). (This includes RHEL/CentOS 8 as the patch
+    luckily isn't included there anymore with XZ Utils 5.2.4.)
+    
+    Binaries built by RHEL/CentOS 7 users get distributed and then
+    people wonder why they don't run on some other distribution.
+    Seems that people have found out about the patch and been copying
+    it to some build scripts, seemingly curing the symptoms but
+    actually spreading the illness further and outside RHEL/CentOS 7.
+    
+    The ill patch seems to be from late 2016 (RHEL 7.3) and in 2017 it
+    had spread at least to EasyBuild. I heard about the events only
+    recently. :-(
+    
+    This commit splits liblzma.map into two versions: one for
+    GNU/Linux and another for other OSes that can use symbol versioning
+    (FreeBSD, Solaris, maybe others). The Linux-specific file and the
+    matching additions to .c files add full compatibility with binaries
+    that have been built against a RHEL/CentOS-patched liblzma. Builds
+    for OSes other than GNU/Linux won't get the vaccine as they should
+    be immune to the problem (I really hope that no build script uses
+    the RHEL/CentOS 7 patch outside GNU/Linux).
+    
+    The RHEL/CentOS compatibility symbols XZ_5.1.2alpha and XZ_5.2.2
+    are intentionally put *after* XZ_5.2 in liblzma_linux.map. This way
+    if one forgets to #define HAVE_SYMBOL_VERSIONS_LINUX when building,
+    the resulting liblzma.so.5 will have lzma_stream_encoder_mt@@XZ_5.2
+    since XZ_5.2 {...} is the first one that lists that function.
+    Without HAVE_SYMBOL_VERSIONS_LINUX @XZ_5.1.2alpha and @XZ_5.2.2
+    will be missing but that's still a minor problem compared to
+    only having lzma_stream_encoder_mt@@XZ_5.1.2alpha!
+    
+    The "local: *;" line was moved to XZ_5.0 so that it doesn't need
+    to be moved around. It doesn't matter where it is put.
+    
+    Having two similar liblzma_*.map files is a bit silly as it is,
+    at least for now, easily possible to generate the generic one
+    from the Linux-specific file. But that adds extra steps and
+    increases the risk of mistakes when supporting more than one
+    build system. So I rather maintain two files in parallel and let
+    validate_map.sh check that they are in sync when "make mydist"
+    is run.
+    
+    This adds .symver lines for lzma_stream_encoder_mt@XZ_5.2.2 and
+    lzma_stream_encoder_mt_memusage@XZ_5.2.2 even though these
+    weren't exported by RHEL/CentOS 7 (only @@XZ_5.1.2alpha was
+    for these two). I added these anyway because someone might
+    misunderstand the RHEL/CentOS 7 patch and think that @XZ_5.2.2
+    (@@XZ_5.2.2) versions were exported too.
+    
+    At glance one could suggest using __typeof__ to copy the function
+    prototypes when making aliases. However, this doesn't work trivially
+    because __typeof__ won't copy attributes (lzma_nothrow, lzma_pure)
+    and it won't change symbol visibility from hidden to default (done
+    by LZMA_API()). Attributes could be copied with __copy__ attribute
+    but that needs GCC 9 and a fallback method would be needed anyway.
+    
+    This uses __symver__ attribute with GCC >= 10 and
+    __asm__(".symver ...") with everything else. The attribute method
+    is required for LTO (-flto) support with GCC. Using -flto with
+    GCC older than 10 is now broken on GNU/Linux and will not be fixed
+    (can silently result in a broken liblzma build that has dangerously
+    incorrect symbol versions). LTO builds with Clang seem to work
+    with the traditional __asm__(".symver ...") method.
+    
+    Thanks to Boud Roukema for reporting the problem and discussing
+    the details and testing the fix.

+    liblzma: Threaded decoder: Improve LZMA_FAIL_FAST when LZMA_FINISH is used.
+    
+    It will now return LZMA_DATA_ERROR (not LZMA_OK or LZMA_BUF_ERROR)
+    if LZMA_FINISH is used and there isn't enough input to finish
+    decoding the Block Header or the Block. The use of LZMA_DATA_ERROR
+    is simpler and the less risky than LZMA_BUF_ERROR but this might
+    be changed before 5.4.0.

+
+    xzgrep: Improve error handling, especially signals.
+    
+    xzgrep wouldn't exit on SIGPIPE or SIGQUIT when it clearly
+    should have. It's quite possible that it's not perfect still
+    but at least it's much better.
+    
+    If multiple exit statuses compete, now it tries to pick
+    the largest of value.
+    
+    Some comments were added.
+    
+    The exit status handling of signals is still broken if the shell
+    uses values larger than 255 in $? to indicate that a process
+    died due to a signal ***and*** their "exit" command doesn't take
+    this into account. This seems to work well with the ksh and yash
+    versions I tried. However, there is a report in gzip/zgrep that
+    OpenSolaris 5.11 (not 5.10) has a problem with "exit" truncating
+    the argument to 8 bits:
+    
+        https://debbugs.gnu.org/cgi/bugreport.cgi?bug=22900#25
+    
+    Such a bug would break xzgrep but I didn't add a workaround
+    at least for now. 5.11 is old and I don't know if the problem
+    exists in modern descendants, or if the problem exists in other
+    ksh implementations in use.

+Author: Lasse Collin <lasse.collin@tukaani.org>
+Date:   2022-07-18 21:52:31 +0300
+
+    xzgrep: Use grep -H --label when available (GNU, *BSDs).
+    
+    It avoids the use of sed for prefixing filenames to output lines.
+    Using sed for that is slower and prone to security bugs so now
+    the sed method is only used as a fallback.
+    
+    This also fixes an actual bug: When grepping a binary file,
+    GNU grep nowadays prints its diagnostics to stderr instead of
+    stdout and thus the sed-method for prefixing the filename doesn't
+    work. So with this commit grepping binary files gives reasonable
+    output with GNU grep now.
+    
+    This was inspired by zgrep but the implementation is different.

+
+    xzgrep: Add more LC_ALL=C to avoid bugs with multibyte characters.
+    
+    Also replace one use of expr with printf.
+    
+    The rationale for LC_ALL=C was already mentioned in
+    69d1b3fc29677af8ade8dc15dba83f0589cb63d6 that fixed a security
+    issue. However, unrelated uses weren't changed in that commit yet.
+    
+    POSIX says that with sed and such tools one should use LC_ALL=C
+    to ensure predictable behavior when strings contain byte sequences
+    that aren't valid multibyte characters in the current locale. See
+    under "Application usage" in here:
+    
+    https://pubs.opengroup.org/onlinepubs/9699919799/utilities/sed.html
+    
+    With GNU sed invalid multibyte strings would work without this;
+    it's documented in its Texinfo manual. Some other implementations
+    aren't so forgiving.

+
+    xzgrep: Fix parsing of certain options.
+    
+    Fix handling of "xzgrep -25 foo" (in GNU grep "grep -25 foo" is
+    an alias for "grep -C25 foo"). xzgrep would treat "foo" as filename
+    instead of as a pattern. This bug was fixed in zgrep in gzip in 2012.
+    
+    Add -E, -F, -G, and -P to the "no argument required" list.
+    
+    Add -X to "argument required" list. It is an
+    intentionally-undocumented GNU grep option so this isn't
+    an important option for xzgrep but it seems that other grep
+    implementations (well, those that I checked) don't support -X
+    so I hope this change is an improvement still.
+    
+    grep -d (grep --directories=ACTION) requires an argument. In
+    contrast to zgrep, I kept -d in the "no argument required" list
+    because it's not supported in xzgrep (or zgrep). This way
+    "xzgrep -d" gives an error about option being unsupported instead
+    of telling that it requires an argument. Both zgrep and xzgrep
+    tell that it's unsupported if an argument is specified.
+    
+    Add comments.

+
+    liblzma: Add optional autodetection of LZMA end marker.
+    
+    Turns out that this is needed for .lzma files as the spec in
+    LZMA SDK says that end marker may be present even if the size
+    is stored in the header. Such files are rare but exist in the
+    real world. The code in liblzma is so old that the spec didn't
+    exist in LZMA SDK back then and I had understood that such
+    files weren't possible (the lzma tool in LZMA SDK didn't
+    create such files).
+    
+    This modifies the internal API so that LZMA decoder can be told
+    if EOPM is allowed even when the uncompressed size is known.
+    It's allowed with .lzma and not with other uses.
+    
+    Thanks to Karl Beldan for reporting the problem.

+
+    xz: Add a default soft memory usage limit for --threads=0.
+    
+    This is a soft limit in sense that it only affects the number of
+    threads. It never makes xz fail and it never makes xz change
+    settings that would affect the compressed output.
+    
+    The idea is to make -T0 have more reasonable behavior when
+    the system has very many cores or when a memory-hungry
+    compression options are used. This also helps with 32-bit xz,
+    preventing it from running out of address space.
+    
+    The downside of this commit is that now the number of threads
+    might become too low compared to what the user expected. I
+    hope this to be an acceptable compromise as the old behavior
+    has been a source of well-argued complaints for a long time.

+
+    xz: Make -T0 use multithreaded mode on single-core systems.
+    
+    The main problem withi the old behavior is that the compressed
+    output is different on single-core systems vs. multicore systems.
+    This commit fixes it by making -T0 one thread in multithreaded mode
+    on single-core systems.
+    
+    The downside of this is that it uses more memory. However, if
+    --memlimit-compress is used, xz can (thanks to the previous commit)
+    drop to the single-threaded mode still.

+
+    xz: Changes to --memlimit-compress and --no-adjust.
+    
+    In single-threaded mode, --memlimit-compress can make xz scale down
+    the LZMA2 dictionary size to meet the memory usage limit. This
+    obviously affects the compressed output. However, if xz was in
+    threaded mode, --memlimit-compress could make xz reduce the number
+    of threads but it wouldn't make xz switch from multithreaded mode
+    to single-threaded mode or scale down the LZMA2 dictionary size.
+    This seemed illogical and there was even a "FIXME?" about it.
+    
+    Now --memlimit-compress can make xz switch to single-threaded
+    mode if one thread in multithreaded mode uses too much memory.
+    If memory usage is still too high, then the LZMA2 dictionary
+    size can be scaled down too.
+    
+    The option --no-adjust was also changed so that it no longer
+    prevents xz from scaling down the number of threads as that
+    doesn't affect compressed output (only performance). After
+    this commit --no-adjust only prevents adjustments that affect
+    compressed output, that is, with --no-adjust xz won't switch
+    from multithreaded mode to single-threaded mode and won't
+    scale down the LZMA2 dictionary size.
+    
+    The man page wasn't updated yet.

+
+    xz: Add --memlimit-mt-decompress along with a default limit value.
+    
+    --memlimit-mt-decompress allows specifying the limit for
+    multithreaded decompression. This matches memlimit_threading in
+    liblzma. This limit can only affect the number of threads being
+    used; it will never prevent xz from decompressing a file. The
+    old --memlimit-decompress option is still used at the same time.
+    
+    If the value of --memlimit-decompress (the default value or
+    one specified by the user) is less than the value of
+    --memlimit-mt-decompress , then --memlimit-mt-decompress is
+    reduced to match --memlimit-decompress.

+
+    liblzma: Threaded decoder: Support zpipe.c-style decoding loop.
+    
+    This makes it possible to call lzma_code() in a loop that only
+    reads new input when lzma_code() didn't fill the output buffer
+    completely. That isn't the calling style suggested by the
+    liblzma example program 02_decompress.c so perhaps the usefulness
+    of this feature is limited.
+    
+    Also, it is possible to write such a loop so that it works
+    with the single-threaded decoder but not with the threaded
+    decoder even after this commit, or so that it works only if
+    lzma_mt.timeout = 0.
+    
+    The zlib tutorial <https://zlib.net/zlib_how.html> is a well-known
+    example of a loop where more input is read only when output isn't
+    full. Porting this as is to liblzma would work with the
+    single-threaded decoder (if LZMA_CONCATENATED isn't used) but it
+    wouldn't work with threaded decoder even after this commit because
+    the loop assumes that no more output is possible when it cannot
+    read more input ("if (strm.avail_in == 0) break;"). This cannot
+    be fixed at liblzma side; the loop has to be modified at least
+    a little.
+    
+    I'm adding this in any case because the actual code is simple
+    and short and should have no harmful side-effects in other
+    situations.

+    xzgrep: Fix escaping of malicious filenames (ZDI-CAN-16587).
+    
+    Malicious filenames can make xzgrep to write to arbitrary files
+    or (with a GNU sed extension) lead to arbitrary code execution.
+    
+    xzgrep from XZ Utils versions up to and including 5.2.5 are
+    affected. 5.3.1alpha and 5.3.2alpha are affected as well.
+    This patch works for all of them.
+    
+    This bug was inherited from gzip's zgrep. gzip 1.12 includes
+    a fix for zgrep.
+    
+    The issue with the old sed script is that with multiple newlines,
+    the N-command will read the second line of input, then the
+    s-commands will be skipped because it's not the end of the
+    file yet, then a new sed cycle starts and the pattern space
+    is printed and emptied. So only the last line or two get escaped.
+    
+    One way to fix this would be to read all lines into the pattern
+    space first. However, the included fix is even simpler: All lines
+    except the last line get a backslash appended at the end. To ensure
+    that shell command substitution doesn't eat a possible trailing
+    newline, a colon is appended to the filename before escaping.
+    The colon is later used to separate the filename from the grep
+    output so it is fine to add it here instead of a few lines later.
+    
+    The old code also wasn't POSIX compliant as it used \n in the
+    replacement section of the s-command. Using \<newline> is the
+    POSIX compatible method.
+    
+    LC_ALL=C was added to the two critical sed commands. POSIX sed
+    manual recommends it when using sed to manipulate pathnames
+    because in other locales invalid multibyte sequences might
+    cause issues with some sed implementations. In case of GNU sed,
+    these particular sed scripts wouldn't have such problems but some
+    other scripts could have, see:
+    
+        info '(sed)Locale Considerations'
+    
+    This vulnerability was discovered by:
+    cleemy desu wayo working with Trend Micro Zero Day Initiative
+    
+    Thanks to Jim Meyering and Paul Eggert discussing the different
+    ways to fix this and for coordinating the patch release schedule
+    with gzip.

+    liblzma: Fix a deadlock in threaded decoder.
+    
+    If a worker thread has consumed all input so far and it's
+    waiting on thr->cond and then the main thread enables
+    partial update for that thread, the code used to deadlock.
+    This commit allows one dummy decoding pass to occur in this
+    situation which then also does the partial update.
+    
+    As part of the fix, this moves thr->progress_* updates to
+    avoid the second thr->mutex locking.
+    
+    Thanks to Jia Tan for finding, debugging, and reporting the bug.

+
+    xz: Add initial support for threaded decompression.
+    
+    If threading support is enabled at build time, this will
+    use lzma_stream_decoder_mt() even for single-threaded mode.
+    With memlimit_threading=0 the behavior should be identical.
+    
+    This needs some work like adding --memlimit-threading=LIMIT.
+    
+    The original patch from Sebastian Andrzej Siewior included
+    a method to get currently available RAM on Linux. It might
+    be one way to go but as it is Linux-only, the available-RAM
+    approach needs work for portability or using a fallback method
+    on other OSes.
+    
+    The man page wasn't updated yet.

+    liblzma: Add new output queue (lzma_outq) features.
+    
+    Add lzma_outq_clear_cache2() which may leave one buffer allocated
+    in the cache.
+    
+    Add lzma_outq_outbuf_memusage() to get the memory needed for
+    a single lzma_outbuf. This is now used internally in outqueue.c too.
+    
+    Track both the total amount of memory allocated and the amount of
+    memory that is in active use (not in cache).
+    
+    In lzma_outbuf, allow storing the current input position that
+    matches the current output position. This way the main thread
+    can notice when no more output is possible without first providing
+    more input.
+    
+    Allow specifying return code for lzma_outq_read() in a finished
+    lzma_outbuf.

+
+    liblzma: Make Block decoder catch certain types of errors better.
+    
+    Now it limits the input and output buffer sizes that are
+    passed to a raw decoder. This way there's no need to check
+    if the sizes can grow too big or overflow when updating
+    Compressed Size and Uncompressed Size counts. This also means
+    that a corrupt file cannot cause the raw decoder to process
+    useless extra input or output that would exceed the size info
+    in Block Header (and thus cause LZMA_DATA_ERROR anyway).
+    
+    More importantly, now the size information is verified more
+    carefully in case raw decoder returns LZMA_OK. This doesn't
+    really matter with the current single-threaded .xz decoder
+    as the errors would be detected slightly later anyway. But
+    this helps avoiding corner cases in the upcoming threaded
+    decompressor, and it might help other Block decoder uses
+    outside liblzma too.
+    
+    The test files bad-1-lzma2-{9,10,11}.xz test these conditions.
+    With the single-threaded .xz decoder the only difference is
+    that LZMA_DATA_ERROR is detected in a difference place now.

+    userspace process on MIPS32 is limited to 2 GiB, not 4, even on systems
+    that have more physical RAM -- e.g. 64-bit systems with 32-bit
+    userspace, or systems that use XPA (an extension similar to x86's PAE).
+    
+    So, for MIPS32, we have to impose stronger memory limits. I've chosen
+    2000MiB to give the process some headroom.

+
+    CMake: Try to improve compatibility with the FindLibLZMA module.
+    
+    The naming conflict with FindLibLZMA module gets worse.
+    Not avoiding it in the first place was stupid.
+    
+    Normally find_package(LibLZMA) will use the module and
+    find_package(liblzma 5.2.5 REQUIRED CONFIG) will use the config
+    file even with a case insensitive file system. However, if
+    CMAKE_FIND_PACKAGE_PREFER_CONFIG is TRUE and the file system
+    is case insensitive, find_package(LibLZMA) will find our liblzma
+    config file instead of using FindLibLZMA module.
+    
+    One big problem with this is that FindLibLZMA uses
+    LibLZMA::LibLZMA and we use liblzma::liblzma as the target
+    name. With target names CMake happens to be case sensitive.
+    To workaround this, this commit adds
+    
+        add_library(LibLZMA::LibLZMA ALIAS liblzma::liblzma)
+    
+    to the config file. Then both spellings work.
+    
+    To make the behavior consistent between case sensitive and
+    insensitive file systems, the config and related files are
+    renamed from liblzmaConfig.cmake to liblzma-config.cmake style.
+    With this style CMake looks for lowercase version of the package
+    name so find_package(LiBLzmA 5.2.5 REQUIRED CONFIG) will work
+    to find our config file.
+    
+    There are other differences between our config file and
+    FindLibLZMA so it's still possible that things break for
+    reasons other than the spelling of the target name. Hopefully
+    those situations aren't too common.
+    
+    When the config file is available, it should always give as good or
+    better results as FindLibLZMA so this commit doesn't affect the
+    recommendation to use find_package(liblzma 5.2.5 REQUIRED CONFIG)
+    which explicitly avoids FindLibLZMA.
+    
+    Thanks to Markus Rickert.

+
+    liblzma: Add EROFS LZMA encoder and decoder.
+    
+    Right now this is just a planned extra-compact format for use
+    in the EROFS file system in Linux. At this point it's possible
+    that the format will either change or be abandoned and removed
+    completely.
+    
+    The special thing about the encoder is that it uses the
+    output-size-limited encoding added in the previous commit.
+    EROFS uses fixed-sized blocks (e.g. 4 KiB) to hold compressed
+    data so the compressors must be able to create valid streams
+    that fill the given block size.

+
+    liblzma: Add rough support for output-size-limited encoding in LZMA1.
+    
+    With this it is possible to encode LZMA1 data without EOPM so that
+    the encoder will encode as much input as it can without exceeding
+    the specified output size limit. The resulting LZMA1 stream will
+    be a normal LZMA1 stream without EOPM. The actual uncompressed size
+    will be available to the caller via the uncomp_size pointer.
+    
+    One missing thing is that the LZMA layer doesn't inform the LZ layer
+    when the encoding is finished and thus the LZ may read more input
+    when it won't be used. However, this doesn't matter if encoding is
+    done with a single call (which is the planned use case for now).
+    For proper multi-call encoding this should be improved.
+    
+    This commit only adds the functionality for internal use.
+    Nothing uses it yet.

+    xz: Make --keep accept symlinks, hardlinks, and setuid/setgid/sticky.

+
+    Scripts: Fix exit status of xzgrep.
+    
+    Omit the -q option from xz, gzip, and bzip2. With xz this shouldn't
+    matter. With gzip it's important because -q makes gzip replace SIGPIPE
+    with exit status 2. With bzip2 it's important because with -q bzip2
+    is completely silent if input is corrupt while other decompressors
+    still give an error message.
+    
+    Avoiding exit status 2 from gzip is important because bzip2 uses
+    exit status 2 to indicate corrupt input. Before this commit xzgrep
+    didn't recognize corrupt .bz2 files because xzgrep was treating
+    exit status 2 as SIGPIPE for gzip compatibility.
+    
+    zstd still needs -q because otherwise it is noisy in normal
+    operation.
+    
+    The code to detect real SIGPIPE didn't check if the exit status
+    was due to a signal (>= 128) and so could ignore some other exit
+    status too.

+
+    Scripts: Fix exit status of xzdiff/xzcmp.
+    
+    This is a minor fix since this affects only the situation when
+    the files differ and the exit status is something else than 0.
+    In such case there could be SIGPIPE from a decompression tool
+    and that would result in exit status of 2 from xzdiff/xzcmp
+    while the correct behavior would be to return 1 or whatever
+    else diff or cmp may have returned.
+    
+    This commit omits the -q option from xz/gzip/bzip2/lzop arguments.
+    I'm not sure why the -q was used in the first place, perhaps it
+    hides warnings in some situation that I cannot see at the moment.
+    Hopefully the removal won't introduce a new bug.
+    
+    With gzip the -q option was harmful because it made gzip return 2
+    instead of >= 128 with SIGPIPE. Ignoring exit status 2 (warning
+    from gzip) isn't practical because bzip2 uses exit status 2 to
+    indicate corrupt input file. It's better if SIGPIPE results in
+    exit status >= 128.
+    
+    With bzip2 the removal of -q seems to be good because with -q
+    it prints nothing if input is corrupt. The other tools aren't
+    silent in this situation even with -q. On the other hand, if
+    zstd support is added, it will need -q since otherwise it's
+    noisy in normal situations.
+    
+    Thanks to Étienne Mollier and Sebastian Andrzej Siewior.

+    liblzma: Make lzma_outq usable for threaded decompression too.
+    
+    Before this commit all output queue buffers were allocated as
+    a single big allocation. Now each buffer is allocated separately
+    when needed. Used buffers are cached to avoid reallocation
+    overhead but the cache will keep only one buffer size at a time.
+    This should make things work OK in the decompression where most
+    of the time the buffer sizes will be the same but with some less
+    common files the buffer sizes may vary.
+    
+    While this should work fine, it's still a bit preliminary
+    and may even get reverted if it turns out to be useless for
+    decompression.

+    xz: Avoid the abbreviation "e.g." on the man page.
+    
+    A few are simply omitted, most are converted to "for example"
+    and surrounded with commas. Sounds like that this is better
+    style, for example, man-pages(7) recommends avoiding such
+    abbreviations except in parenthesis.
+    
+    Thanks to Bjarni Ingi Gislason.

+
+    xz man page: Change \- (minus) to \(en (en-dash) for a numeric range.
+    
+    Docs of ancient troff/nroff mention \(em (em-dash) but not \(en
+    and \- was used for both minus and en-dash. I don't know how
+    portable \(en is nowadays but it can be changed back if someone
+    complains. At least GNU groff and OpenBSD's mandoc support it.
+    
+    Thanks to Bjarni Ingi Gislason for the patch.

+
+    Build: Fix bugs in the CMake files.
+    
+    Seems that the phrase "add more quotes" from sh/bash scripting
+    applies to CMake as well. E.g. passing an unquoted list ${FOO}
+    to a function that expects one argument results in only the
+    first element of the list being passed as an argument and
+    the rest get ignored. Adding quotes helps ("${FOO}").
+    
+    list(INSERT ...) is weird. Inserting an empty string to an empty
+    variable results in empty list, but inserting it to a non-empty
+    variable does insert an empty element to the list.
+    
+    Since INSERT requires at least one element,
+    "${CMAKE_THREAD_LIBS_INIT}" needs to be quoted in CMakeLists.txt.
+    It might result in an empty element in the list. It seems to not
+    matter as empty elements consistently get ignored in that variable.
+    In fact, calling cmake_check_push_state() and cmake_check_pop_state()
+    will strip the empty elements from CMAKE_REQUIRED_LIBRARIES!
+    
+    In addition to quoting fixes, this fixes checks for the cache
+    variables in tuklib_cpucores.cmake and tuklib_physmem.cmake.
+    
+    Thanks to Martin Matuška for testing and reporting the problems.
+    These fixes aren't tested yet but hopefully they soon will be.

+    Build: Add very limited experimental CMake support.
+    
+    This does *NOT* replace the Autotools-based build system in
+    the foreseeable future. See the comment in the beginning

+    
+    So far this has been tested only on GNU/Linux but I commit

+    haven't played much with CMake before, it's likely that
+    there are things that have been done in a silly or wrong

+    Revert the previous commit and add a comment.
+    
+    The previous commit broke crc32_tablegen.c.
+    
+    If the whole package is built without config.h (with defines
+    set on the compiler command line) this should still work fine
+    as long as these headers conform to C99 well enough.

+
+    Build: Add support for translated man pages using po4a.
+    
+    The dependency on po4a is optional. It's never required to install
+    the translated man pages when xz is built from a release tarball.
+    If po4a is missing when building from xz.git, the translated man
+    pages won't be generated but otherwise the build will work normally.
+    
+    The translations are only updated automatically by autogen.sh and
+    by "make mydist". This makes it easy to keep po4a as an optional
+    dependency and ensures that I won't forget to put updated
+    translations to a release tarball.
+    
+    The translated man pages aren't installed if --disable-nls is used.
+    
+    The installation of translated man pages abuses Automake internals
+    by calling "install-man" with redefined dist_man_MANS and man_MANS.
+    This makes the hairy script code slightly less hairy. If it breaks
+    some day, this code needs to be fixed; don't blame Automake developers.
+    
+    Also, this adds more quotes to the existing shell script code in
+    the Makefile.am "-hook"s.

+    I don't know if the problem is in gnulib's gl_POSIX_SHELL macro

+    use that shell for xzgrep and other scripts. That shell is known

+    xz: Limit --memlimit-compress to at most 4020 MiB for 32-bit xz.
+    
+    See the code comment for reasoning. It's far from perfect but
+    hopefully good enough for certain cases while hopefully doing
+    nothing bad in other situations.
+    
+    At presets -5 ... -9, 4020 MiB vs. 4096 MiB makes no difference
+    on how xz scales down the number of threads.
+    
+    The limit has to be a few MiB below 4096 MiB because otherwise
+    things like "xz --lzma2=dict=500MiB" won't scale down the dict
+    size enough and xz cannot allocate enough memory. With
+    "ulimit -v $((4096 * 1024))" on x86-64, the limit in xz had
+    to be no more than 4085 MiB. Some safety margin is good though.
+    
+    This is hack but it should be useful when running 32-bit xz on
+    a 64-bit kernel that gives full 4 GiB address space to xz.
+    Hopefully this is enough to solve this:
+    
+    https://bugzilla.redhat.com/show_bug.cgi?id=1196786
+    
+    FreeBSD has a patch that limits the result in tuklib_physmem()
+    to SIZE_MAX on 32-bit systems. While I think it's not the way
+    to do it, the results on --memlimit-compress have been good. This
+    commit should achieve practically identical results for compression
+    while leaving decompression and tuklib_physmem() and thus
+    lzma_physmem() unaffected.

+    xz: Set the --flush-timeout deadline when the first input byte arrives.
+    
+    xz --flush-timeout=2000, old version:
+    
+      1. xz is started. The next flush will happen after two seconds.
+      2. No input for one second.
+      3. A burst of a few kilobytes of input.
+      4. No input for one second.
+      5. Two seconds have passed and flushing starts.
+    
+    The first second counted towards the flush-timeout even though
+    there was no pending data. This can cause flushing to occur more
+    often than needed.
+    
+    xz --flush-timeout=2000, after this commit:
+    
+      1. xz is started.
+      2. No input for one second.
+      3. A burst of a few kilobytes of input. The next flush will
+         happen after two seconds counted from the time when the
+         first bytes of the burst were read.
+      4. No input for one second.
+      5. No input for another second.
+      6. Two seconds have passed and flushing starts.

+
+    Revise tuklib_integer.h and .m4.
+    
+    Add a configure option --enable-unsafe-type-punning to get the
+    old non-conforming memory access methods. It can be useful with
+    old compilers or in some other less typical situations but
+    shouldn't normally be used.
+    
+    Omit the packed struct trick for unaligned access. While it's
+    best in some cases, this is simpler. If the memcpy trick doesn't
+    work, one can request unsafe type punning from configure.
+    
+    Because CRC32/CRC64 code needs fast aligned reads, if no very
+    safe way to do it is found, type punning is used as a fallback.
+    This sucks but since it currently works in practice, it seems to
+    be the least bad option. It's never needed with GCC >= 4.7 or
+    Clang >= 3.6 since these support __builtin_assume_aligned and
+    thus fast aligned access can be done with the memcpy trick.
+    
+    Other things:
+      - Support GCC/Clang __builtin_bswapXX
+      - Cleaner bswap fallback macros
+      - Minor cleanups

+
+    Add LZMA_RET_INTERNAL1..8 to lzma_ret and use one for LZMA_TIMED_OUT.
+    
+    LZMA_TIMED_OUT is *internally* used as a value for lzma_ret
+    enumeration. Previously it was #defined to 32 and cast to lzma_ret.
+    That way it wasn't visible in the public API, but this was hackish.
+    
+    Now the public API has eight LZMA_RET_INTERNALx members and
+    LZMA_TIMED_OUT is #defined to LZMA_RET_INTERNAL1. This way
+    the code is cleaner overall although the public API has a few
+    extra mysterious enum members.

+    tuklib_integer: Improve unaligned memory access.

+    Now memcpy() or GNU C packed structs for unaligned access instead

+    New functions: unaliged_readXXne and unaligned_writeXXne where

+
+    liblzma: Avoid memcpy(NULL, foo, 0) because it is undefined behavior.
+    
+    I should have always known this but I didn't. Here is an example
+    as a reminder to myself:
+    
+        int mycopy(void *dest, void *src, size_t n)
+        {
+            memcpy(dest, src, n);
+            return dest == NULL;
+        }
+    
+    In the example, a compiler may assume that dest != NULL because
+    passing NULL to memcpy() would be undefined behavior. Testing
+    with GCC 8.2.1, mycopy(NULL, NULL, 0) returns 1 with -O0 and -O1.
+    With -O2 the return value is 0 because the compiler infers that
+    dest cannot be NULL because it was already used with memcpy()
+    and thus the test for NULL gets optimized out.
+    
+    In liblzma, if a null-pointer was passed to memcpy(), there were
+    no checks for NULL *after* the memcpy() call, so I cautiously
+    suspect that it shouldn't have caused bad behavior in practice,
+    but it's hard to be sure, and the problematic cases had to be
+    fixed anyway.
+    
+    Thanks to Jeffrey Walton.

+    xz: In xz -lvv look at the widths of the check names too.
+    
+    Now the widths of the check names is used to adjust the width
+    of the Check column. This way there no longer is a need to restrict
+    the widths of the check names to be at most ten terminal-columns.

+
+    Windows/VS2017: Omit WindowsTargetPlatformVersion from project files.
+    
+    I understood that if a WTPV is specified, it's often wrong
+    because different VS installations have different SDK version
+    installed. Omitting the WTPV tag makes VS2017 default to
+    Windows SDK 8.1 which often is also missing, so in any case
+    people may need to specify the WTPV before building. But some
+    day in the future a missing WTPV tag will start to default to
+    the latest installed SDK which sounds reasonable:
+    
+    https://developercommunity.visualstudio.com/content/problem/140294/windowstargetplatformversion-makes-it-impossible-t.html
+    
+    Thanks to "dom".

+    xz: Fix a crash in progress indicator when in passthru mode.
+    
+    "xz -dcfv not_an_xz_file" crashed (all four options are
+    required to trigger it). It caused xz to call
+    lzma_get_progress(&strm, ...) when no coder was initialized
+    in strm. In this situation strm.internal is NULL which leads
+    to a crash in lzma_get_progress().
+    
+    The bug was introduced when xz started using lzma_get_progress()
+    to get progress info for multi-threaded compression, so the
+    bug is present in versions 5.1.3alpha and higher.
+    
+    Thanks to Filip Palian <Filip.Palian@pjwstk.edu.pl> for
+    the bug report.

+    liblzma: Don't verify header CRC32s if building for fuzz testing.
+    
+    FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION is #defined when liblzma
+    is being built for fuzz testing.
+    
+    Most fuzzed inputs would normally get rejected because of incorrect
+    CRC32 and the actual header decoding code wouldn't get fuzzed.
+    Disabling CRC32 checks avoids this problem. The fuzzer program
+    must still use LZMA_IGNORE_CHECK flag to disable verification of
+    integrity checks of uncompressed data.

+
+    xz: Fix "xz --list --robot missing_or_bad_file.xz".
+    
+    It ended up printing an uninitialized char-array when trying to
+    print the check names (column 7) on the "totals" line.
+    
+    This also changes the column 12 (minimum xz version) to
+    50000002 (xz 5.0.0) instead of 0 when there are no valid
+    input files.
+    
+    Thanks to kidmin for the bug report.

+
+    liblzma: Fix lzma_memlimit_set(strm, 0).
+    
+    The 0 got treated specially in a buggy way and as a result
+    the function did nothing. The API doc said that 0 was supposed
+    to return LZMA_PROG_ERROR but it didn't.
+    
+    Now 0 is treated as if 1 had been specified. This is done because
+    0 is already used to indicate an error from lzma_memlimit_get()
+    and lzma_memusage().
+    
+    In addition, lzma_memlimit_set() no longer checks that the new
+    limit is at least LZMA_MEMUSAGE_BASE. It's counter-productive
+    for the Index decoder and was actually needed only by the
+    auto decoder. Auto decoder has now been modified to check for
+    LZMA_MEMUSAGE_BASE.

+
+    liblzma: Fix handling of memlimit == 0 in lzma_index_decoder().
+    
+    It returned LZMA_PROG_ERROR, which was done to avoid zero as
+    the limit (because it's a special value elsewhere), but using
+    LZMA_PROG_ERROR is simply inconvenient and can cause bugs.
+    
+    The fix/workaround is to treat 0 as if it were 1 byte. It's
+    effectively the same thing. The only weird consequence is
+    that then lzma_memlimit_get() will return 1 even when 0 was
+    specified as the limit.
+    
+    This fixes a very rare corner case in xz --list where a specific
+    memory usage limit and a multi-stream file could print the
+    error message "Internal error (bug)" instead of saying that
+    the memory usage limit is too low.

+    tuklib_cpucores: Add support for sched_getaffinity().
+    
+    It's available in glibc (GNU/Linux, GNU/kFreeBSD). It's better
+    than sysconf(_SC_NPROCESSORS_ONLN) because sched_getaffinity()
+    gives the number of cores available to the process instead of
+    the total number of cores online.
+    
+    As a side effect, this commit fixes a bug on GNU/kFreeBSD where
+    configure would detect the FreeBSD-specific cpuset_getaffinity()
+    but it wouldn't actually work because on GNU/kFreeBSD it requires
+    using -lfreebsd-glue when linking. Now the glibc-specific function
+    will be used instead.
+    
+    Thanks to Sebastian Andrzej Siewior for the original patch
+    and testing.

+
+    liblzma: Disable external SHA-256 by default.
+    
+    This is the sane thing to do. The conflict with OpenSSL
+    on some OSes and especially that the OS-provided versions
+    can be significantly slower makes it clear that it was
+    a mistake to have the external SHA-256 support enabled by
+    default.
+    
+    Those who want it can now pass --enable-external-sha256 to
+    configure. INSTALL was updated with notes about OSes where
+    this can be a bad idea.
+    
+    The SHA-256 detection code in configure.ac had some bugs that
+    could lead to a build failure in some situations. These were
+    fixed, although it doesn't matter that much now that the
+    external SHA-256 is disabled by default.
+    
+    MINIX >= 3.2.0 uses NetBSD's libc and thus has SHA256_Init
+    in libc instead of libutil. Support for the libutil version
+    was removed.

+
+    Build: Avoid SHA256_Init on FreeBSD and MINIX 3.
+    
+    On FreeBSD 10 and older, SHA256_Init from libmd conflicts
+    with libcrypto from OpenSSL. The OpenSSL version has
+    different sizeof(SHA256_CTX) and it can cause weird
+    problems if wrong SHA256_Init gets used.
+    
+    Looking at the source, MINIX 3 seems to have a similar issue but
+    I'm not sure. To be safe, I disabled SHA256_Init on MINIX 3 too.
+    
+    NetBSD has SHA256_Init in libc and they had a similar problem,
+    but they already fixed it in 2009.
+    
+    Thanks to Jim Wilcoxson for the bug report that helped
+    in finding the problem.

+    liblzma: Make Valgrind happier with optimized (gcc -O2) liblzma.
+    
+    When optimizing, GCC can reorder code so that an uninitialized
+    value gets used in a comparison, which makes Valgrind unhappy.
+    It doesn't happen when compiled with -O0, which I tend to use
+    when running Valgrind.
+    
+    Thanks to Rich Prohaska. I remember this being mentioned long
+    ago by someone else but nothing was done back then.

+    xz: Make xz buildable even when encoders or decoders are disabled.
+    
+    The patch is quite long but it's mostly about adding new #ifdefs
+    to omit code when encoders or decoders have been disabled.
+    
+    This adds two new #defines to config.h: HAVE_ENCODERS and
+    HAVE_DECODERS.

+
+    Build: Build LZMA1/2 presets also when only decoder is wanted.
+    
+    People shouldn't rely on the presets when decoding raw streams,
+    but xz uses the presets as the starting point for raw decoder
+    options anyway.
+    
+    lzma_encocder_presets.c was renamed to lzma_presets.c to
+    make it clear it's not used solely by the encoder code.

+    liblzma: Fix a memory leak in error path of lzma_index_dup().
+    
+    lzma_index_dup() calls index_dup_stream() which, in case of
+    an error, calls index_stream_end() to free memory allocated
+    by index_stream_init(). However, it illogically didn't
+    actually free the memory. To make it logical, the tree
+    handling code was modified a bit in addition to changing
+    index_stream_end().
+    
+    Thanks to Evan Nemerson for the bug report.

+    Update German translation, mostly wrt orthography
+    
+    Provide an update of the German translation.
+    * A lot of compound words were previously written with spaces, while
+      German orthography is relatively clear in that the components
+      should not be separated.
+    * When referring to the actual process of (de)compression rather than the
+      concept, replace “(De-)Kompression” with “(De-)Komprimierung”.
+      Previously, both forms were used in this context and are now used in a
+      manner consistent with “Komprimierung” being more likely to refer to
+      a process.
+    * Consistently translate “standard input”/“output”
+    * Use “Zeichen” instead of false friend “Charakter” for “character”
+    * Insert commas around relative clauses (as required in German)
+    * Some other minor corrections
+    * Capitalize “ß” as “ẞ”
+    * Consistently start option descriptions in --help with capital letters

+    
+    This reverts commit 7a11c4a8e5e15f13d5fa59233b3172e65428efdd.
+    It is a problem when libc has pipe2() but the kernel is too
+    old to have pipe2() and thus pipe2() fails. In xz it's pointless
+    to have a fallback for non-functioning pipe2(); it's better to
+    avoid pipe2() completely.
+    
+    Thanks to Michael Fox for the bug report.

+    xz: Add support for sandboxing with Capsicum.
+    
+    The sandboxing is used conditionally as described in main.c.
+    This isn't optimal but it was much easier to implement than
+    a full sandboxing solution and it still covers the most common
+    use cases where xz is writing to standard output. This should
+    have practically no effect on performance even with small files
+    as fork() isn't needed.
+    
+    C and locale libraries can open files as needed. This has been
+    fine in the past, but it's a problem with things like Capsicum.
+    io_sandbox_enter() tries to ensure that various locale-related
+    files have been loaded before cap_enter() is called, but it's
+    possible that there are other similar problems which haven't
+    been seen yet.
+    
+    Currently Capsicum is available on FreeBSD 10 and later
+    and there is a port to Linux too.
+    
+    Thanks to Loganaden Velvindron for help.

+commit 29a087fb5a0c879f0b1bc4c6b989f7b87bacdf9e
+Author: Lasse Collin <lasse.collin@tukaani.org>
+Date:   2015-03-31 21:12:30 +0300
+
+    Fix bugs and otherwise improve ax_check_capsicum.m4.
+    
+    AU_ALIAS was removed because the new version is incompatible
+    with the old version.
+    
+    It no longer checks for <sys/capability.h> separately.
+    It's enough to test for it as part of AC_CHECK_DECL.
+    The defines HAVE_CAPSICUM_SYS_CAPSICUM_H and
+    HAVE_CAPSICUM_SYS_CAPABILITY_H were removed as unneeded.
+    HAVE_SYS_CAPSICUM_H from AC_CHECK_HEADERS is enough.
+    
+    It no longer does a useless search for the Capsicum library
+    if the header wasn't found.
+    
+    Fixed a bug in ACTION-IF-FOUND (the first argument). Specifying
+    the argument omitted the default action but the given action
+    wasn't used instead.
+    
+    AC_DEFINE([HAVE_CAPSICUM]) is now always called when Capsicum
+    support is found. Previously it was part of the default
+    ACTION-IF-FOUND which a custom action would override. Now
+    the default action only prepends ${CAPSICUM_LIB} to LIBS.
+    
+    The documentation was updated.
+    
+    Since there as no serial number, "#serial 2" was added.

+
+    Fix CPU core count detection on QNX.
+    
+    It tried to use sysctl() on QNX but
+      - it broke the build because sysctl() needs -lsocket on QNX;
+      - sysctl() doesn't work for detecting the core count on QNX
+        even if it compiled.
+    
+    sysconf() works. An alternative would have been to use
+    QNX-specific SYSPAGE_ENTRY(num_cpu) from <sys/syspage.h>.
+    
+    Thanks to Ole André Vadla Ravnås.

+
+    xz: Don't fail if stdin doesn't support O_NONBLOCK.
+    
+    It's a problem at least on OpenBSD which doesn't support
+    O_NONBLOCK on e.g. /dev/null. I'm not surprised if it's
+    a problem on other OSes too since this behavior is allowed
+    in POSIX-1.2008.
+    
+    The code relying on this behavior was committed in June 2013
+    and included in 5.1.3alpha released on 2013-10-26. Clearly
+    the development releases only get limited testing.

+0. Preface
+----------
+
+    If you aren't familiar with building packages that use GNU Autotools,
+    see the file INSTALL.generic for generic instructions before reading
+    further.
+
+    If you are going to build a package for distribution, see also the
+    file PACKAGERS. It contains information that should help making the
+    binary packages as good as possible, but the information isn't very
+    interesting to those making local builds for private use or for use
+    in special situations like embedded systems.
+
+
+1. Supported platforms
+----------------------
+
+    XZ Utils are developed on GNU/Linux, but they should work on many
+    POSIX-like operating systems like *BSDs and Solaris, and even on
+    a few non-POSIX operating systems.
+
+
+1.1. Compilers
+
+    A C99 compiler is required to compile XZ Utils. If you use GCC, you
+    need at least version 3.x.x. GCC version 2.xx.x doesn't support some
+    C99 features used in XZ Utils source code, thus GCC 2 won't compile
+    XZ Utils.
+
+    XZ Utils takes advantage of some GNU C extensions when building
+    with GCC. Because these extensions are used only when building
+    with GCC, it should be possible to use any C99 compiler.
+
+
+1.2. Platform-specific notes
+
+1.2.1. AIX
+
+    If you use IBM XL C compiler, pass CC=xlc_r to configure. If
+    you use CC=xlc instead, you must disable threading support
+    with --disable-threads (usually not recommended).
+
+
+1.2.2. IRIX
+
+    MIPSpro 7.4.4m has been reported to produce broken code if using
+    the -O2 optimization flag ("make check" fails). Using -O1 should
+    work.
+
+    A problem has been reported when using shared liblzma. Passing
+    --disable-shared to configure works around this. Alternatively,
+    putting "-64" to CFLAGS to build a 64-bit version might help too.
+
+
+1.2.3. MINIX 3
+
+    The default install of MINIX 3 includes Amsterdam Compiler Kit (ACK),
+    which doesn't support C99. Install GCC to compile XZ Utils.
+
+    MINIX 3.1.8 and older have bugs in /usr/include/stdint.h, which has
+    to be patched before XZ Utils can be compiled correctly. See
+    <http://gforge.cs.vu.nl/gf/project/minix/tracker/?action=TrackerItemEdit&tracker_item_id=537>.
+
+    MINIX 3.2.0 and later use a different libc and aren't affected by
+    the above bug.
+
+    XZ Utils doesn't have code to detect the amount of physical RAM and
+    number of CPU cores on MINIX 3.
+
+    See section 5.4 in this file about symbol visibility warnings (you
+    may want to pass gl_cv_cc_visibility=no to configure).
+
+
+1.2.4. OpenVMS
+
+    XZ Utils can be built for OpenVMS, but the build system files
+    are not included in the XZ Utils source package. The required
+    OpenVMS-specific files are maintained by Jouk Jansen and can be
+    downloaded here:
+
+        http://nchrem.tnw.tudelft.nl/openvms/software2.html#xzutils
+
+
+1.2.5. Solaris, OpenSolaris, and derivatives
+
+    The following linker error has been reported on some x86 systems:
+
+        ld: fatal: relocation error: R_386_GOTOFF: ...
+
+    This can be worked around by passing gl_cv_cc_visibility=no
+    as an argument to the configure script.
+
+    test_scripts.sh in "make check" may fail if good enough tools are
+    missing from PATH (/usr/xpg4/bin or /usr/xpg6/bin). Nowadays
+    /usr/xpg4/bin is added to the script PATH by default on Solaris
+    (see --enable-path-for-scripts=PREFIX in section 2), but old xz
+    releases needed extra steps. See sections 5.5 and 3.2 for more
+    information.
+
+
+1.2.6. Tru64
+
+    If you try to use the native C compiler on Tru64 (passing CC=cc to
+    configure), you may need the workaround mention in section 5.1 in
+    this file (pass also ac_cv_prog_cc_c99= to configure).
+
+
+1.2.7. Windows
+
+    If it is enough to build liblzma (no command line tools):
+
+      - There is CMake support. It should be good enough to build
+        static liblzma or liblzma.dll with Visual Studio. The CMake
+        support may work with MinGW or MinGW-w64. Read the comment
+        in the beginning of CMakeLists.txt before running CMake!
+
+      - There are Visual Studio project files under the "windows"
+        directory. See windows/INSTALL-MSVC.txt. In the future the
+        project files will be removed when CMake support is good
+        enough. Thus, please test the CMake version and help fix
+        possible issues.
+
+    To build also the command line tools:
+
+      - MinGW-w64 + MSYS (32-bit and 64-bit x86): This is used
+        for building the official binary packages for Windows.
+        There is windows/build.bash to ease packaging XZ Utils with
+        MinGW(-w64) + MSYS into a redistributable .zip or .7z file.
+        See windows/INSTALL-MinGW.txt for more information.
+
+      - MinGW + MSYS (32-bit x86): I haven't recently tested this.
+
+      - Cygwin 1.7.35 and later: NOTE that using XZ Utils >= 5.2.0
+        under Cygwin older than 1.7.35 can lead to DATA LOSS! If
+        you must use an old Cygwin version, stick to XZ Utils 5.0.x
+        which is safe under older Cygwin versions. You can check
+        the Cygwin version with the command "cygcheck -V".
+
+    It may be possible to build liblzma with other toolchains too, but
+    that will probably require writing a separate makefile. Building
+    the command line tools with non-GNU toolchains will be harder than
+    building only liblzma.
+
+    Even if liblzma is built with MinGW(-w64), the resulting DLL can
+    be used by other compilers and linkers, including MSVC. See
+    windows/README-Windows.txt for details.
+
+
+1.2.8. DOS
+
+    There is a Makefile in the "dos" directory to build XZ Utils on
+    DOS using DJGPP. Support for long file names (LFN) is needed at
+    build time but the resulting xz.exe works without LFN support too.
+    See dos/INSTALL.txt and dos/README.txt for more information.
+
+
+1.2.9. z/OS
+
+    To build XZ Utils on z/OS UNIX System Services using xlc, pass
+    these options to the configure script: CC='xlc -qhaltonmsg=CCN3296'
+    CPPFLAS='-D_UNIX03_THREADS -D_XOPEN_SOURCE=600'. The first makes
+    xlc throw an error if a header file is missing, which is required
+    to make the tests in configure work. The CPPFLAGS are needed to
+    get pthread support (some other CPPFLAGS may work too; if there
+    are problems, try -D_UNIX95_THREADS instead of -D_UNIX03_THREADS).
+
+    test_scripts.sh in "make check" will fail even if the scripts
+    actually work because the test data includes compressed files
+    with US-ASCII text.
+
+    No other tests should fail. If test_files.sh fails, check that
+    the included .xz test files weren't affected by EBCDIC conversion.
+
+    XZ Utils doesn't have code to detect the amount of physical RAM and
+    number of CPU cores on z/OS.
+
+
+1.3. Adding support for new platforms
+
+    If you have written patches to make XZ Utils to work on previously
+    unsupported platform, please send the patches to me! I will consider
+    including them to the official version. It's nice to minimize the
+    need of third-party patching.
+
+    One exception: Don't request or send patches to change the whole
+    source package to C89. I find C99 substantially nicer to write and
+    maintain. However, the public library headers must be in C89 to
+    avoid frustrating those who maintain programs, which are strictly
+    in C89 or C++.
+
+
+2. configure options
+--------------------
+
+    In most cases, the defaults are what you want. Many of the options
+    below are useful only when building a size-optimized version of
+    liblzma or command line tools.
+
+    --enable-encoders=LIST
+    --disable-encoders
+                Specify a comma-separated LIST of filter encoders to
+                build. See "./configure --help" for exact list of
+                available filter encoders. The default is to build all
+                supported encoders.
+
+                If LIST is empty or --disable-encoders is used, no filter
+                encoders will be built and also the code shared between
+                encoders will be omitted.
+
+                Disabling encoders will remove some symbols from the
+                liblzma ABI, so this option should be used only when it
+                is known to not cause problems.
+
+    --enable-decoders=LIST
+    --disable-decoders
+                This is like --enable-encoders but for decoders. The
+                default is to build all supported decoders.
+
+    --enable-match-finders=LIST
+                liblzma includes two categories of match finders:
+                hash chains and binary trees. Hash chains (hc3 and hc4)
+                are quite fast but they don't provide the best compression
+                ratio. Binary trees (bt2, bt3 and bt4) give excellent
+                compression ratio, but they are slower and need more
+                memory than hash chains.
+
+                You need to enable at least one match finder to build the
+                LZMA1 or LZMA2 filter encoders. Usually hash chains are
+                used only in the fast mode, while binary trees are used to
+                when the best compression ratio is wanted.
+
+                The default is to build all the match finders if LZMA1
+                or LZMA2 filter encoders are being built.
+
+    --enable-checks=LIST
+                liblzma support multiple integrity checks. CRC32 is
+                mandatory, and cannot be omitted. See "./configure --help"
+                for exact list of available integrity check types.
+
+                liblzma and the command line tools can decompress files
+                which use unsupported integrity check type, but naturally
+                the file integrity cannot be verified in that case.
+
+                Disabling integrity checks may remove some symbols from
+                the liblzma ABI, so this option should be used only when
+                it is known to not cause problems.
+
+    --enable-external-sha256
+                Try to use SHA-256 code from the operating system libc
+                or similar base system libraries. This doesn't try to
+                use OpenSSL or libgcrypt or such libraries.
+
+                The reasons to use this option:
+
+                  - It makes liblzma slightly smaller.
+
+                  - It might improve SHA-256 speed if the implementation
+                    in the operating is very good (but see below).
+
+                External SHA-256 is disabled by default for two reasons:
+
+                  - On some operating systems the symbol names of the
+                    SHA-256 functions conflict with OpenSSL's libcrypto.
+                    This causes weird problems such as decompression
+                    errors if an application is linked against both
+                    liblzma and libcrypto. This problem affects at least
+                    FreeBSD 10 and older and MINIX 3.3.0 and older, but
+                    other OSes that provide a function "SHA256_Init" might
+                    also be affected. FreeBSD 11 has the problem fixed.
+                    NetBSD had the problem but it was fixed it in 2009
+                    already. OpenBSD uses "SHA256Init" and thus never had
+                    a conflict with libcrypto.
+
+                  - The SHA-256 code in liblzma is faster than the SHA-256
+                    code provided by some operating systems. If you are
+                    curious, build two copies of xz (internal and external
+                    SHA-256) and compare the decompression (xz --test)
+                    times:
+
+                        dd if=/dev/zero bs=1024k count=1024 \
+                            | xz -v -0 -Csha256 > foo.xz
+                        time xz --test foo.xz
+
+    --disable-microlzma
+                Don't build MicroLZMA encoder and decoder. This omits
+                lzma_microlzma_encoder() and lzma_microlzma_decoder()
+                API functions from liblzma. These functions are needed
+                by specific applications only. They were written for
+                erofs-utils but they may be used by others too.
+
+    --disable-lzip-decoder
+                Disable decompression support for .lz (lzip) files.
+                This omits the API function lzma_lzip_decoder() from
+                liblzma and .lz support from the xz tool.
+
+    --disable-xz
+    --disable-xzdec
+    --disable-lzmadec
+    --disable-lzmainfo
+                Don't build and install the command line tool mentioned
+                in the option name.
+
+                NOTE: Disabling xz will skip some tests in "make check".
+
+                NOTE: If xzdec is disabled and lzmadec is left enabled,
+                a dangling man page symlink lzmadec.1 -> xzdec.1 is
+                created.
+
+    --disable-lzma-links
+                Don't create symlinks for LZMA Utils compatibility.
+                This includes lzma, unlzma, and lzcat. If scripts are
+                installed, also lzdiff, lzcmp, lzgrep, lzegrep, lzfgrep,
+                lzmore, and lzless will be omitted if this option is used.
+
+    --disable-scripts
+                Don't install the scripts xzdiff, xzgrep, xzmore, xzless,
+                and their symlinks.
+
+    --disable-doc
+                Don't install the documentation files to $docdir
+                (often /usr/doc/xz or /usr/local/doc/xz). Man pages
+                will still be installed. The $docdir can be changed
+                with --docdir=DIR.
+
+    --disable-assembler
+                liblzma includes some assembler optimizations. Currently
+                there is only assembler code for CRC32 and CRC64 for
+                32-bit x86.
+
+                All the assembler code in liblzma is position-independent
+                code, which is suitable for use in shared libraries and
+                position-independent executables. So far only i386
+                instructions are used, but the code is optimized for i686
+                class CPUs. If you are compiling liblzma exclusively for
+                pre-i686 systems, you may want to disable the assembler
+                code.
+
+    --disable-clmul-crc
+                Disable the use carryless multiplication for CRC
+                calculation even if compiler support for it is detected.
+                The code uses runtime detection of SSSE3, SSE4.1, and
+                CLMUL instructions on x86. On 32-bit x86 this currently
+                is used only if --disable-assembler is used (this might
+                be fixed in the future). The code works on E2K too.
+
+                If using compiler options that unconditionally allow the
+                required extensions (-msse4.1 -mpclmul) then runtime
+                detection isn't used and the generic code is omitted.
+
+    --enable-unaligned-access
+                Allow liblzma to use unaligned memory access for 16-bit,
+                32-bit, and 64-bit loads and stores. This should be
+                enabled only when the hardware supports this, that is,
+                when unaligned access is fast. Some operating system
+                kernels emulate unaligned access, which is extremely
+                slow. This option shouldn't be used on systems that
+                rely on such emulation.
+
+                Unaligned access is enabled by default on x86, x86-64,
+                big endian PowerPC, some ARM, and some ARM64 systems.
+
+    --enable-unsafe-type-punning
+                This enables use of code like
+
+                    uint8_t *buf8 = ...;
+                    *(uint32_t *)buf8 = ...;
+
+                which violates strict aliasing rules and may result
+                in broken code. There should be no need to use this
+                option with recent GCC or Clang versions on any
+                arch as just as fast code can be generated in a safe
+                way too (using __builtin_assume_aligned + memcpy).
+
+                However, this option might improve performance in some
+                other cases, especially with old compilers (for example,
+                GCC 3 and early 4.x on x86, GCC < 6 on ARMv6 and ARMv7).
+
+    --enable-small
+                Reduce the size of liblzma by selecting smaller but
+                semantically equivalent version of some functions, and
+                omit precomputed lookup tables. This option tends to
+                make liblzma slightly slower.
+
+                Note that while omitting the precomputed tables makes
+                liblzma smaller on disk, the tables are still needed at
+                run time, and need to be computed at startup. This also
+                means that the RAM holding the tables won't be shared
+                between applications linked against shared liblzma.
+
+                This option doesn't modify CFLAGS to tell the compiler
+                to optimize for size. You need to add -Os or equivalent
+                flag(s) to CFLAGS manually.
+
+    --enable-assume-ram=SIZE
+                On the most common operating systems, XZ Utils is able to
+                detect the amount of physical memory on the system. This
+                information is used by the options --memlimit-compress,
+                --memlimit-decompress, and --memlimit when setting the
+                limit to a percentage of total RAM.
+
+                On some systems, there is no code to detect the amount of
+                RAM though. Using --enable-assume-ram one can set how much
+                memory to assume on these systems. SIZE is given as MiB.
+                The default is 128 MiB.
+
+                Feel free to send patches to add support for detecting
+                the amount of RAM on the operating system you use. See
+                src/common/tuklib_physmem.c for details.
+
+    --enable-threads=METHOD
+                Threading support is enabled by default so normally there
+                is no need to specify this option.
+
+                Supported values for METHOD:
+
+                        yes     Autodetect the threading method. If none
+                                is found, configure will give an error.
+
+                        posix   Use POSIX pthreads. This is the default
+                                except on Windows outside Cygwin.
+
+                        win95   Use Windows 95 compatible threads. This
+                                is compatible with Windows XP and later
+                                too. This is the default for 32-bit x86
+                                Windows builds. Unless the compiler
+                                supports __attribute__((__constructor__)),
+                                the `win95' threading is incompatible with
+                                --enable-small.
+
+                        vista   Use Windows Vista compatible threads. The
+                                resulting binaries won't run on Windows XP
+                                or older. This is the default for Windows
+                                excluding 32-bit x86 builds (that is, on
+                                x86-64 the default is `vista').
+
+                        no      Disable threading support. This is the
+                                same as using --disable-threads.
+                                NOTE: If combined with --enable-small
+                                and the compiler doesn't support
+                                __attribute__((__constructor__)), the
+                                resulting liblzma won't be thread safe,
+                                that is, if a multi-threaded application
+                                calls any liblzma functions from more than
+                                one thread, something bad may happen.
+
+    --enable-sandbox=METHOD
+                There is limited sandboxing support in the xz tool. If
+                built with sandbox support, it's used automatically when
+                (de)compressing exactly one file to standard output and
+                the options --files or --files0 weren't used. This is a
+                common use case, for example, (de)compressing .tar.xz
+                files via GNU tar. The sandbox is also used for
+                single-file `xz --test' or `xz --list'.
+
+                Supported METHODs:
+
+                        auto    Look for a supported sandboxing method
+                                and use it if found. If no method is
+                                found, then sandboxing isn't used.
+                                This is the default.
+
+                        no      Disable sandboxing support.
+
+                        capsicum
+                                Use Capsicum (FreeBSD >= 10) for
+                                sandboxing. If no Capsicum support
+                                is found, configure will give an error.
+
+                        pledge  Use pledge(2) (OpenBSD >= 5.9) for
+                                sandboxing. If pledge(2) isn't found,
+                                configure will give an error.
+
+    --enable-symbol-versions
+                Use symbol versioning for liblzma. This is enabled by
+                default on GNU/Linux, other GNU-based systems, and
+                FreeBSD.
+
+    --enable-debug
+                This enables the assert() macro and possibly some other
+                run-time consistency checks. It makes the code slower, so
+                you normally don't want to have this enabled.
+
+    --enable-werror
+                If building with GCC, make all compiler warnings an error,
+                that abort the compilation. This may help catching bugs,
+                and should work on most systems. This has no effect on the
+                resulting binaries.
+
+    --enable-path-for-scripts=PREFIX
+                If PREFIX isn't empty, PATH=PREFIX:$PATH will be set in
+                the beginning of the scripts (xzgrep and others).
+                The default is empty except on Solaris the default is
+                /usr/xpg4/bin.
+
+                This can be useful if the default PATH doesn't contain
+                modern POSIX tools (as can be the case on Solaris) or if
+                one wants to ensure that the correct xz binary is in the
+                PATH for the scripts. Note that the latter use can break
+                "make check" if the prefixed PATH causes a wrong xz binary
+                (other than the one that was just built) to be used.
+
+                Older xz releases support a different method for setting
+                the PATH for the scripts. It is described in section 3.2
+                and is supported in this xz version too.
+
+
+2.1. Static vs. dynamic linking of liblzma
+
+    On 32-bit x86, linking against static liblzma can give a minor
+    speed improvement. Static libraries on x86 are usually compiled as
+    position-dependent code (non-PIC) and shared libraries are built as
+    position-independent code (PIC). PIC wastes one register, which can
+    make the code slightly slower compared to a non-PIC version. (Note
+    that this doesn't apply to x86-64.)
+
+    If you want to link xz against static liblzma, the simplest way
+    is to pass --disable-shared to configure. If you want also shared
+    liblzma, run configure again and run "make install" only for
+    src/liblzma.
+
+
+2.2. Optimizing xzdec and lzmadec
+
+    xzdec and lzmadec are intended to be relatively small instead of
+    optimizing for the best speed. Thus, it is a good idea to build
+    xzdec and lzmadec separately:
+
+      - To link the tools against static liblzma, pass --disable-shared
+        to configure.
+
+      - To select somewhat size-optimized variant of some things in
+        liblzma, pass --enable-small to configure.
+
+      - Tell the compiler to optimize for size instead of speed.
+        For example, with GCC, put -Os into CFLAGS.
+
+      - xzdec and lzmadec will never use multithreading capabilities of
+        liblzma. You can avoid dependency on libpthread by passing
+        --disable-threads to configure.
+
+      - There are and will be no translated messages for xzdec and
+        lzmadec, so it is fine to pass also --disable-nls to configure.
+
+      - Only decoder code is needed, so you can speed up the build
+        slightly by passing --disable-encoders to configure. This
+        shouldn't affect the final size of the executables though,
+        because the linker is able to omit the encoder code anyway.
+
+    If you have no use for xzdec or lzmadec, you can disable them with
+    --disable-xzdec and --disable-lzmadec.
+
+
+3. xzgrep and other scripts
+---------------------------
+
+3.1. Dependencies
+
+    POSIX shell (sh) and bunch of other standard POSIX tools are required
+    to run the scripts. The configure script tries to find a POSIX
+    compliant sh, but if it fails, you can force the shell by passing
+    gl_cv_posix_shell=/path/to/posix-sh as an argument to the configure
+    script.
+
+    xzdiff (xzcmp/lzdiff/lzcmp) may use mktemp if it is available. As
+    a fallback xzdiff will use mkdir to securely create a temporary
+    directory. Having mktemp available is still recommended since the
+    mkdir fallback method isn't as robust as mktemp is. The original
+    mktemp can be found from <https://www.mktemp.org/>. On GNU, most will
+    use the mktemp program from GNU coreutils instead of the original
+    implementation. Both mktemp versions are fine.
+
+    In addition to using xz to decompress .xz files, xzgrep and xzdiff
+    use gzip, bzip2, and lzop to support .gz, bz2, and .lzo files.
+
+
+3.2. PATH
+
+    The method described below is supported by older xz releases.
+    It is supported by the current version too, but the newer
+    --enable-path-for-scripts=PREFIX described in section 2 may be
+    more convenient.
+
+    The scripts assume that the required tools (standard POSIX utilities,
+    mktemp, and xz) are in PATH; the scripts don't set the PATH themselves
+    (except as described for --enable-path-for-scripts=PREFIX). Some
+    people like this while some think this is a bug. Those in the latter
+    group can easily patch the scripts before running the configure script
+    by taking advantage of a placeholder line in the scripts.
+
+    For example, to make the scripts prefix /usr/bin:/bin to PATH:
+
+        perl -pi -e 's|^#SET_PATH.*$|PATH=/usr/bin:/bin:\$PATH|' \
+                src/scripts/xz*.in
+
+
+4. Tests
+--------
+
+    The test framework can be built and run by executing "make check" in
+    the build directory. The tests are a mix of executables and POSIX
+    shell scripts (sh). All tests should pass if the default configuration
+    is used. Disabling features through the configure options may cause
+    some tests to be skipped. If any tests do not pass, see section 5.5.
+
+
+4.1. Testing in parallel
+
+    The tests can be run in parallel using the "-j" make option on systems
+    that support it. For instance, "make -j4 check" will run up to four
+    tests simultaneously.
+
+
+4.2. Cross compiling
+
+    The tests can be built without running them:
+
+        make check TESTS=
+
+    The TESTS variable is the list of tests you wish to run. Leaving it
+    empty will compile the tests without running any.
+
+    If the tests are copied to a target machine to execute, the test data
+    files in the directory tests/files must also be copied. The tests
+    search for the data files using the environment variable $srcdir,
+    expecting to find the data files under $srcdir/files/. If $srcdir
+    isn't set then it defaults to the current directory.
+
+    The shell script tests can be copied from the source directory to the
+    target machine to execute. In addition to the test files, these tests
+    will expect the following relative file paths to execute properly:
+
+        ./create_compress_files
+        ../config.h
+        ../src/xz/xz
+        ../src/xzdec/xzdec
+        ../src/scripts/xzdiff
+        ../src/scripts/xzgrep
+
+
+5. Troubleshooting
+------------------
+
+5.1. "No C99 compiler was found."
+
+    You need a C99 compiler to build XZ Utils. If the configure script
+    cannot find a C99 compiler and you think you have such a compiler
+    installed, set the compiler command by passing CC=/path/to/c99 as
+    an argument to the configure script.
+
+    If you get this error even when you think your compiler supports C99,
+    you can override the test by passing ac_cv_prog_cc_c99= as an argument
+    to the configure script. The test for C99 compiler is not perfect (and
+    it is not as easy to make it perfect as it sounds), so sometimes this
+    may be needed. You will get a compile error if your compiler doesn't
+    support enough C99.
+
+
+5.2. "No POSIX conforming shell (sh) was found."
+
+    xzgrep and other scripts need a shell that (roughly) conforms
+    to POSIX. The configure script tries to find such a shell. If
+    it fails, you can force the shell to be used by passing
+    gl_cv_posix_shell=/path/to/posix-sh as an argument to the configure
+    script. Alternatively you can omit the installation of scripts and
+    this error by passing --disable-scripts to configure.
+
+
+5.3. configure works but build fails at crc32_x86.S
+
+    The easy fix is to pass --disable-assembler to the configure script.
+
+    The configure script determines if assembler code can be used by
+    looking at the configure triplet; there is currently no check if
+    the assembler code can actually actually be built. The x86 assembler
+    code should work on x86 GNU/Linux, *BSDs, Solaris, Darwin, MinGW,
+    Cygwin, and DJGPP. On other x86 systems, there may be problems and
+    the assembler code may need to be disabled with the configure option.
+
+    If you get this error when building for x86-64, you have specified or
+    the configure script has misguessed your architecture. Pass the
+    correct configure triplet using the --build=CPU-COMPANY-SYSTEM option
+    (see INSTALL.generic).
+
+
+5.4. Lots of warnings about symbol visibility
+
+    On some systems where symbol visibility isn't supported, GCC may
+    still accept the visibility options and attributes, which will make
+    configure think that visibility is supported. This will result in
+    many compiler warnings. You can avoid the warnings by forcing the
+    visibility support off by passing gl_cv_cc_visibility=no as an
+    argument to the configure script. This has no effect on the
+    resulting binaries, but fewer warnings looks nicer and may allow
+    using --enable-werror.
+
+
+5.5. "make check" fails
+
+    If the other tests pass but test_scripts.sh fails, then the problem
+    is in the scripts in src/scripts. Comparing the contents of
+    tests/xzgrep_test_output to tests/xzgrep_expected_output might
+    give a good idea about problems in xzgrep. One possibility is that
+    some tools are missing from the current PATH or the tools lack
+    support for some POSIX features. This can happen at least on
+    Solaris where the tools in /bin may be ancient but good enough
+    tools are available in /usr/xpg4/bin or /usr/xpg6/bin. For possible
+    fixes, see --enable-path-for-scripts=PREFIX in section 2 and the
+    older alternative method described in section 3.2 of this file.
+
+    If tests other than test_scripts.sh fail, a likely reason is that
+    libtool links the test programs against an installed version of
+    liblzma instead of the version that was just built. This is
+    obviously a bug which seems to happen on some platforms.
+    A workaround is to uninstall the old liblzma versions first.
+
+    If the problem isn't any of those described above, then it's likely
+    a bug in XZ Utils or in the compiler. See the platform-specific
+    notes in this file for possible known problems. Please report
+    a bug if you cannot solve the problem. See README for contact
+    information.
+
+
+5.6. liblzma.so (or similar) not found when running xz
+
+    If you installed the package with "make install" and get an error
+    about liblzma.so (or a similarly named file) being missing, try
+    running "ldconfig" to update the run-time linker cache (if your
+    operating system has such a command).

+
+Basic Installation
+==================
+
+   Briefly, the shell command './configure && make && make install'
+should configure, build, and install this package.  The following
+more-detailed instructions are generic; see the 'README' file for
+instructions specific to this package.  Some packages provide this
+'INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The 'configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a 'Makefile' in each directory of the package.
+It may also create one or more '.h' files containing system-dependent
+definitions.  Finally, it creates a shell script 'config.status' that
+you can run in the future to recreate the current configuration, and a
+file 'config.log' containing compiler output (useful mainly for
+debugging 'configure').
+
+   It can also use an optional file (typically called 'config.cache' and
+enabled with '--cache-file=config.cache' or simply '-C') that saves the
+results of its tests to speed up reconfiguring.  Caching is disabled by
+default to prevent problems with accidental use of stale cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how 'configure' could check whether to do them, and mail
+diffs or instructions to the address given in the 'README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point 'config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file 'configure.ac' (or 'configure.in') is used to create
+'configure' by a program called 'autoconf'.  You need 'configure.ac' if
+you want to change it or regenerate 'configure' using a newer version of
+'autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. 'cd' to the directory containing the package's source code and type
+     './configure' to configure the package for your system.
+
+     Running 'configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type 'make' to compile the package.
+
+  3. Optionally, type 'make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type 'make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the 'make install' phase executed with root
+     privileges.
+
+  5. Optionally, type 'make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior 'make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing 'make clean'.  To also remove the
+     files that 'configure' created (so you can compile the package for
+     a different kind of computer), type 'make distclean'.  There is
+     also a 'make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type 'make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide 'make
+     distcheck', which can by used by developers to test that all other
+     targets like 'make install' and 'make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the 'configure' script does not know about.  Run './configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give 'configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here is
+an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU 'make'.  'cd' to the
+directory where you want the object files and executables to go and run
+the 'configure' script.  'configure' automatically checks for the source
+code in the directory that 'configure' is in and in '..'.  This is known
+as a "VPATH" build.
+
+   With a non-GNU 'make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use 'make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple '-arch' options to the
+compiler but only a single '-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the 'lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, 'make install' installs the package's commands under
+'/usr/local/bin', include files under '/usr/local/include', etc.  You
+can specify an installation prefix other than '/usr/local' by giving
+'configure' the option '--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option '--exec-prefix=PREFIX' to 'configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like '--bindir=DIR' to specify different values for particular
+kinds of files.  Run 'configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the default
+for these options is expressed in terms of '${prefix}', so that
+specifying just '--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to 'configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+'make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, 'make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+'${prefix}'.  Any directories that were specified during 'configure',
+but not in terms of '${prefix}', must each be overridden at install time
+for the entire installation to be relocated.  The approach of makefile
+variable overrides for each directory variable is required by the GNU
+Coding Standards, and ideally causes no recompilation.  However, some
+platforms have known limitations with the semantics of shared libraries
+that end up requiring recompilation when using this method, particularly
+noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the 'DESTDIR' variable.  For
+example, 'make install DESTDIR=/alternate/directory' will prepend
+'/alternate/directory' before all installation names.  The approach of
+'DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of '${prefix}'
+at 'configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving 'configure' the
+option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'.
+
+   Some packages pay attention to '--enable-FEATURE' options to
+'configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to '--with-PACKAGE' options, where PACKAGE
+is something like 'gnu-as' or 'x' (for the X Window System).  The
+'README' should mention any '--enable-' and '--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, 'configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the 'configure' options '--x-includes=DIR' and
+'--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of 'make' will be.  For these packages, running './configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with 'make V=1'; while running './configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with 'make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU CC
+is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   HP-UX 'make' updates targets which have the same time stamps as their
+prerequisites, which makes it generally unusable when shipped generated
+files such as 'configure' are involved.  Use GNU 'make' instead.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its '<wchar.h>' header file.  The option '-nodtk' can be used as a
+workaround.  If GNU CC is not installed, it is therefore recommended to
+try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put '/usr/ucb' early in your 'PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in '/usr/bin'.  So, if you need '/usr/ucb'
+in your 'PATH', put it _after_ '/usr/bin'.
+
+   On Haiku, software installed for all users goes in '/boot/common',
+not '/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features 'configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, 'configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+'--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as 'sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file 'config.sub' for the possible values of each field.  If
+'config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option '--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with '--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for 'configure' scripts to share,
+you can create a site shell script called 'config.site' that gives
+default values for variables like 'CC', 'cache_file', and 'prefix'.
+'configure' looks for 'PREFIX/share/config.site' if it exists, then
+'PREFIX/etc/config.site' if it exists.  Or, you can set the
+'CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all 'configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to 'configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the 'configure' command line, using 'VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified 'gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an
+Autoconf limitation.  Until the limitation is lifted, you can use this
+workaround:
+
+     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+'configure' Invocation
+======================
+
+   'configure' recognizes the following options to control how it
+operates.
+
+'--help'
+'-h'
+     Print a summary of all of the options to 'configure', and exit.
+
+'--help=short'
+'--help=recursive'
+     Print a summary of the options unique to this package's
+     'configure', and exit.  The 'short' variant lists options used only
+     in the top level, while the 'recursive' variant lists options also
+     present in any nested packages.
+
+'--version'
+'-V'
+     Print the version of Autoconf used to generate the 'configure'
+     script, and exit.
+
+'--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally 'config.cache'.  FILE defaults to '/dev/null' to
+     disable caching.
+
+'--config-cache'
+'-C'
+     Alias for '--cache-file=config.cache'.
+
+'--quiet'
+'--silent'
+'-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to '/dev/null' (any error
+     messages will still be shown).
+
+'--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     'configure' can determine that directory automatically.
+
+'--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names:: for
+     more details, including other options available for fine-tuning the
+     installation locations.
+
+'--no-create'
+'-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+'configure' also accepts some other, not widely useful, options.  Run
+'configure --help' for more details.

+XZ Utils Release Notes
+======================
+
+5.4.5 (2023-11-01)
+
+    * liblzma:
+
+        - Use __attribute__((__no_sanitize_address__)) to avoid address
+          sanitization with CRC64 CLMUL. It uses 16-byte-aligned reads
+          which can extend past the bounds of the input buffer and
+          inherently trigger address sanitization errors. This isn't
+          a bug.
+
+        - Fixed an assertion failure that could be triggered by a large
+          unpadded_size argument. It was verified that there was no
+          other bug than the assertion failure.
+
+        - Fixed a bug that prevented building with Windows Vista
+          threading when __attribute__((__constructor__)) is not
+          supported.
+
+    * xz now properly handles special files such as "con" or "nul" on
+      Windows. Before this fix, the following wrote "foo" to the
+      console and deleted the input file "con_xz":
+
+          echo foo | xz > con_xz
+          xz --suffix=_xz --decompress con_xz
+
+    * Build systems:
+
+        - Allow builds with Windows win95 threading and small mode when
+          __attribute__((__constructor__)) is supported.
+
+        - Added a new line to liblzma.pc for MSYS2 (Windows):
+
+              Cflags.private: -DLZMA_API_STATIC
+
+          When compiling code that will link against static liblzma,
+          the LZMA_API_STATIC macro needs to be defined on Windows.
+
+        - CMake specific changes:
+
+            * Fixed a bug that allowed CLOCK_MONOTONIC to be used even
+              if the check for it failed.
+
+            * Fixed a bug where configuring CMake multiple times
+              resulted in HAVE_CLOCK_GETTIME and HAVE_CLOCK_MONOTONIC
+              not being set.
+
+            * Fixed the build with MinGW-w64-based Clang/LLVM 17.
+              llvm-windres now has more accurate GNU windres emulation
+              so the GNU windres workaround from 5.4.1 is needed with
+              llvm-windres version 17 too.
+
+            * The import library on Windows is now properly named
+              "liblzma.dll.a" instead of "libliblzma.dll.a"
+
+            * Fixed a bug causing the Ninja Generator to fail on
+              UNIX-like systems. This bug was introduced in 5.4.0.
+
+            * Added a new option to disable CLMUL CRC64.
+
+            * A module-definition (.def) file is now created when
+              building liblzma.dll with MinGW-w64.
+
+            * The pkg-config liblzma.pc file is now installed on all
+              builds except when using MSVC on Windows.
+
+            * Added large file support by default for platforms that
+              need it to handle files larger than 2 GiB. This includes
+              MinGW-w64, even 64-bit builds.
+
+    * Small fixes and improvements to the tests.
+
+    * Updated translations: Chinese (simplified) and Esperanto.
+
+
+5.4.4 (2023-08-02)
+
+    * liblzma and xzdec can now build against WASI SDK when threading
+      support is disabled. xz and tests don't build yet.
+
+    * CMake:
+
+        - Fixed a bug preventing other projects from including liblzma
+          multiple times using find_package().
+
+        - Don't create broken symlinks in Cygwin and MSYS2 unless
+          supported by the environment. This prevented building for the
+          default MSYS2 environment. The problem was introduced in
+          xz 5.4.0.
+
+    * Documentation:
+
+        - Small improvements to man pages.
+
+        - Small improvements and typo fixes for liblzma API
+          documentation.
+
+    * Tests:
+
+        - Added a new section to INSTALL to describe basic test usage
+          and address recent questions about building the tests when
+          cross compiling.
+
+        - Small fixes and improvements to the tests.
+
+    * Translations:
+
+        - Fixed a mistake that caused one of the error messages to not
+          be translated. This only affected versions 5.4.2 and 5.4.3.
+
+        - Updated the Chinese (simplified), Croatian, Esperanto, German,
+          Korean, Polish, Romanian, Spanish, Swedish, Ukrainian, and
+          Vietnamese translations.
+
+        - Updated the German, Korean, Romanian, and Ukrainian man page
+          translations.
+
+
+5.4.3 (2023-05-04)
+
+    * All fixes from 5.2.12
+
+    * Features in the CMake build can now be disabled as CMake cache
+      variables, similar to the Autotools build.
+
+    * Minor update to the Croatian translation.
+
+
+5.4.2 (2023-03-18)
+
+    * All fixes from 5.2.11 that were not included in 5.4.1.
+
+    * If xz is built with support for the Capsicum sandbox but running
+      in an environment that doesn't support Capsicum, xz now runs
+      normally without sandboxing instead of exiting with an error.
+
+    * liblzma:
+
+        - Documentation was updated to improve the style, consistency,
+          and completeness of the liblzma API headers.
+
+        - The Doxygen-generated HTML documentation for the liblzma API
+          header files is now included in the source release and is
+          installed as part of "make install". All JavaScript is
+          removed to simplify license compliance and to reduce the
+          install size.
+
+        - Fixed a minor bug in lzma_str_from_filters() that produced
+          too many filters in the output string instead of reporting
+          an error if the input array had more than four filters. This
+          bug did not affect xz.
+
+    * Build systems:
+
+        - autogen.sh now invokes the doxygen tool via the new wrapper
+          script doxygen/update-doxygen, unless the command line option
+          --no-doxygen is used.
+
+        - Added microlzma_encoder.c and microlzma_decoder.c to the
+          VS project files for Windows and to the CMake build. These
+          should have been included in 5.3.2alpha.
+
+    * Tests:
+
+        - Added a test to the CMake build that was forgotten in the
+          previous release.
+
+        - Added and refactored a few tests.
+
+    * Translations:
+
+        - Updated the Brazilian Portuguese translation.
+
+        - Added Brazilian Portuguese man page translation.
+
+
+5.4.1 (2023-01-11)
+
+    * liblzma:
+
+        - Fixed the return value of lzma_microlzma_encoder() if the
+          LZMA options lc/lp/pb are invalid. Invalid lc/lp/pb options
+          made the function return LZMA_STREAM_END without encoding
+          anything instead of returning LZMA_OPTIONS_ERROR.
+
+        - Windows / Visual Studio: Workaround a possible compiler bug
+          when targeting 32-bit x86 and compiling the CLMUL version of
+          the CRC64 code. The CLMUL code isn't enabled by the Windows
+          project files but it is in the CMake-based builds.
+
+    * Build systems:
+
+        - Windows-specific CMake changes:
+
+            * Don't try to enable CLMUL CRC64 code if _mm_set_epi64x()
+              isn't available. This fixes CMake-based build with Visual
+              Studio 2013.
+
+            * Created a workaround for a build failure with windres
+              from GNU binutils. It is used only when the C compiler
+              is GCC (not Clang). The workaround is incompatible
+              with llvm-windres, resulting in "XZx20Utils" instead
+              of "XZ Utils" in the resource file, but without the
+              workaround llvm-windres works correctly. See the
+              comment in CMakeLists.txt for details.
+
+            * Included the resource files in the xz and xzdec build
+              rules. Building the command line tools is still
+              experimental but possible with MinGW-w64.
+
+        - Visual Studio: Added stream_decoder_mt.c to the project
+          files. Now the threaded decompressor lzma_stream_decoder_mt()
+          gets built. CMake-based build wasn't affected.
+
+        - Updated windows/INSTALL-MSVC.txt to mention that CMake-based
+          build is now the preferred method with Visual Studio. The
+          project files will probably be removed after 5.4.x releases.
+
+        - Changes to #defines in config.h:
+
+            * HAVE_DECL_CLOCK_MONOTONIC was replaced by
+              HAVE_CLOCK_MONOTONIC. The old macro was always defined
+              in configure-generated config.h to either 0 or 1. The
+              new macro is defined (to 1) only if the declaration of
+              CLOCK_MONOTONIC is available. This matches the way most
+              other config.h macros work and makes things simpler with
+              other build systems.
+
+            * HAVE_DECL_PROGRAM_INVOCATION_NAME was replaced by
+              HAVE_PROGRAM_INVOCATION_NAME for the same reason.
+
+    * Tests:
+
+        - Fixed test script compatibility with ancient /bin/sh
+          versions. Now the five test_compress_* tests should
+          no longer fail on Solaris 10.
+
+        - Added and refactored a few tests.
+
+    * Translations:
+
+        - Updated the Catalan and Esperanto translations.
+
+        - Added Korean and Ukrainian man page translations.
+
+
+5.4.0 (2022-12-13)
+
+    This bumps the minor version of liblzma because new features were
+    added. The API and ABI are still backward compatible with liblzma
+    5.2.x and 5.0.x.
+
+    Since 5.3.5beta:
+
+    * All fixes from 5.2.10.
+
+    * The ARM64 filter is now stable. The xz option is now --arm64.
+      Decompression requires XZ Utils 5.4.0. In the future the ARM64
+      filter will be supported by XZ for Java, XZ Embedded (including
+      the version in Linux), LZMA SDK, and 7-Zip.
+
+    * Translations:
+
+        - Updated Catalan, Croatian, German, Romanian, and Turkish
+          translations.
+
+        - Updated German man page translations.
+
+        - Added Romanian man page translations.
+
+    Summary of new features added in the 5.3.x development releases:
+
+    * liblzma:
+
+        - Added threaded .xz decompressor lzma_stream_decoder_mt().
+          It can use multiple threads with .xz files that have multiple
+          Blocks with size information in Block Headers. The threaded
+          encoder in xz has always created such files.
+
+          Single-threaded encoder cannot store the size information in
+          Block Headers even if one used LZMA_FULL_FLUSH to create
+          multiple Blocks, so this threaded decoder cannot use multiple
+          threads with such files.
+
+          If there are multiple Streams (concatenated .xz files), one
+          Stream will be decompressed completely before starting the
+          next Stream.
+
+        - A new decoder flag LZMA_FAIL_FAST was added. It makes the
+          threaded decompressor report errors soon instead of first
+          flushing all pending data before the error location.
+
+        - New Filter IDs:
+            * LZMA_FILTER_ARM64 is for ARM64 binaries.
+            * LZMA_FILTER_LZMA1EXT is for raw LZMA1 streams that don't
+              necessarily use the end marker.
+
+        - Added lzma_str_to_filters(), lzma_str_from_filters(), and
+          lzma_str_list_filters() to convert a preset or a filter chain
+          string to a lzma_filter[] and vice versa. These should make
+          it easier to write applications that allow users to specify
+          custom compression options.
+
+        - Added lzma_filters_free() which can be convenient for freeing
+          the filter options in a filter chain (an array of lzma_filter
+          structures).
+
+        - lzma_file_info_decoder() to makes it a little easier to get
+          the Index field from .xz files. This helps in getting the
+          uncompressed file size but an easy-to-use random access
+          API is still missing which has existed in XZ for Java for
+          a long time.
+
+        - Added lzma_microlzma_encoder() and lzma_microlzma_decoder().
+          It is used by erofs-utils and may be used by others too.
+
+          The MicroLZMA format is a raw LZMA stream (without end marker)
+          whose first byte (always 0x00) has been replaced with
+          bitwise-negation of the LZMA properties (lc/lp/pb). It was
+          created for use in EROFS but may be used in other contexts
+          as well where it is important to avoid wasting bytes for
+          stream headers or footers. The format is also supported by
+          XZ Embedded (the XZ Embedded version in Linux got MicroLZMA
+          support in Linux 5.16).
+
+          The MicroLZMA encoder API in liblzma can compress into a
+          fixed-sized output buffer so that as much data is compressed
+          as can be fit into the buffer while still creating a valid
+          MicroLZMA stream. This is needed for EROFS.
+
+        - Added lzma_lzip_decoder() to decompress the .lz (lzip) file
+          format version 0 and the original unextended version 1 files.
+          Also lzma_auto_decoder() supports .lz files.
+
+        - lzma_filters_update() can now be used with the multi-threaded
+          encoder (lzma_stream_encoder_mt()) to change the filter chain
+          after LZMA_FULL_BARRIER or LZMA_FULL_FLUSH.
+
+        - In lzma_options_lzma, allow nice_len = 2 and 3 with the match
+          finders that require at least 3 or 4. Now it is internally
+          rounded up if needed.
+
+        - CLMUL-based CRC64 on x86-64 and E2K with runtime processor
+          detection. On 32-bit x86 it currently isn't available unless
+          --disable-assembler is used which can make the non-CLMUL
+          CRC64 slower; this might be fixed in the future.
+
+        - Building with --disable-threads --enable-small
+          is now thread-safe if the compiler supports
+          __attribute__((__constructor__)).
+
+    * xz:
+
+        - Using -T0 (--threads=0) will now use multi-threaded encoder
+          even on a single-core system. This is to ensure that output
+          from the same xz binary is identical on both single-core and
+          multi-core systems.
+
+        - --threads=+1 or -T+1 is now a way to put xz into
+          multi-threaded mode while using only one worker thread.
+          The + is ignored if the number is not 1.
+
+        - A default soft memory usage limit is now used for compression
+          when -T0 is used and no explicit limit has been specified.
+          This soft limit is used to restrict the number of threads
+          but if the limit is exceeded with even one thread then xz
+          will continue with one thread using the multi-threaded
+          encoder and this limit is ignored. If the number of threads
+          is specified manually then no default limit will be used;
+          this affects only -T0.
+
+          This change helps on systems that have very many cores and
+          using all of them for xz makes no sense. Previously xz -T0
+          could run out of memory on such systems because it attempted
+          to reserve memory for too many threads.
+
+          This also helps with 32-bit builds which don't have a large
+          amount of address space that would be required for many
+          threads. The default soft limit for -T0 is at most 1400 MiB
+          on all 32-bit platforms.
+
+        - Previously a low value in --memlimit-compress wouldn't cause
+          xz to switch from multi-threaded mode to single-threaded mode
+          if the limit cannot otherwise be met; xz failed instead. Now
+          xz can switch to single-threaded mode and then, if needed,
+          scale down the LZMA2 dictionary size too just like it already
+          did when it was started in single-threaded mode.
+
+        - The option --no-adjust no longer prevents xz from scaling down
+          the number of threads as that doesn't affect the compressed
+          output (only performance). Now --no-adjust only prevents
+          adjustments that affect compressed output, that is, with
+          --no-adjust xz won't switch from multi-threaded mode to
+          single-threaded mode and won't scale down the LZMA2
+          dictionary size.
+
+        - Added a new option --memlimit-mt-decompress=LIMIT. This is
+          used to limit the number of decompressor threads (possibly
+          falling back to single-threaded mode) but it will never make
+          xz refuse to decompress a file. This has a system-specific
+          default value because without any limit xz could end up
+          allocating memory for the whole compressed input file, the
+          whole uncompressed output file, multiple thread-specific
+          decompressor instances and so on. Basically xz could
+          attempt to use an insane amount of memory even with fairly
+          common files. The system-specific default value is currently
+          the same as the one used for compression with -T0.
+
+          The new option works together with the existing option
+          --memlimit-decompress=LIMIT. The old option sets a hard limit
+          that must not be exceeded (xz will refuse to decompress)
+          while the new option only restricts the number of threads.
+          If the limit set with --memlimit-mt-decompress is greater
+          than the limit set with --memlimit-compress, then the latter
+          value is used also for --memlimit-mt-decompress.
+
+        - Added new information to the output of xz --info-memory and
+          new fields to the output of xz --robot --info-memory.
+
+        - In --lzma2=nice=NUMBER allow 2 and 3 with all match finders
+          now that liblzma handles it.
+
+        - Don't mention endianness for ARM and ARM-Thumb filters in
+          --long-help. The filters only work for little endian
+          instruction encoding but modern ARM processors using
+          big endian data access still use little endian
+          instruction encoding. So the help text was misleading.
+          In contrast, the PowerPC filter is only for big endian
+          32/64-bit PowerPC code. Little endian PowerPC would need
+          a separate filter.
+
+        - Added decompression support for the .lz (lzip) file format
+          version 0 and the original unextended version 1. It is
+          autodetected by default. See also the option --format on
+          the xz man page.
+
+        - Sandboxing enabled by default:
+            * Capsicum (FreeBSD)
+            * pledge(2) (OpenBSD)
+
+    * Scripts now support the .lz format using xz.
+
+    * A few new tests were added.
+
+    * The liblzma-specific tests are now supported in CMake-based
+      builds too ("make test").
+
+
+5.3.5beta (2022-12-01)
+
+    * All fixes from 5.2.9.
+
+    * liblzma:
+
+        - Added new LZMA_FILTER_LZMA1EXT for raw encoder and decoder to
+          handle raw LZMA1 streams that don't have end of payload marker
+          (EOPM) alias end of stream (EOS) marker. It can be used in
+          filter chains, for example, with the x86 BCJ filter.
+
+        - Added lzma_str_to_filters(), lzma_str_from_filters(), and
+          lzma_str_list_filters() to make it easier for applications
+          to get custom compression options from a user and convert
+          it to an array of lzma_filter structures.
+
+        - Added lzma_filters_free().
+
+        - lzma_filters_update() can now be used with the multi-threaded
+          encoder (lzma_stream_encoder_mt()) to change the filter chain
+          after LZMA_FULL_BARRIER or LZMA_FULL_FLUSH.
+
+        - In lzma_options_lzma, allow nice_len = 2 and 3 with the match
+          finders that require at least 3 or 4. Now it is internally
+          rounded up if needed.
+
+        - ARM64 filter was modified. It is still experimental.
+
+        - Fixed LTO build with Clang if -fgnuc-version=10 or similar
+          was used to make Clang look like GCC >= 10. Now it uses
+          __has_attribute(__symver__) which should be reliable.
+
+    * xz:
+
+        - --threads=+1 or -T+1 is now a way to put xz into multi-threaded
+          mode while using only one worker thread.
+
+        - In --lzma2=nice=NUMBER allow 2 and 3 with all match finders
+          now that liblzma handles it.
+
+    * Updated translations: Chinese (simplified), Korean, and Turkish.
+
+
+5.3.4alpha (2022-11-15)
+
+    * All fixes from 5.2.7 and 5.2.8.
+
+    * liblzma:
+
+        - Minor improvements to the threaded decoder.
+
+        - Added CRC64 implementation that uses SSSE3, SSE4.1, and CLMUL
+          instructions on 32/64-bit x86 and E2K. On 32-bit x86 it's
+          not enabled unless --disable-assembler is used but then
+          the non-CLMUL code might be slower. Processor support is
+          detected at runtime so this is built by default on x86-64
+          and E2K. On these platforms, if compiler flags indicate
+          unconditional CLMUL support (-msse4.1 -mpclmul) then the
+          generic version is not built, making liblzma 8-9 KiB smaller
+          compared to having both versions included.
+
+          With extremely compressible files this can make decompression
+          up to twice as fast but with typical files 5 % improvement
+          is a more realistic expectation.
+
+          The CLMUL version is slower than the generic version with
+          tiny inputs (especially at 1-8 bytes per call, but up to
+          16 bytes). In normal use in xz this doesn't matter at all.
+
+        - Added an experimental ARM64 filter. This is *not* the final
+          version! Files created with this experimental version won't
+          be supported in the future versions! The filter design is
+          a compromise where improving one use case makes some other
+          cases worse.
+
+        - Added decompression support for the .lz (lzip) file format
+          version 0 and the original unextended version 1. See the
+          API docs of lzma_lzip_decoder() for details. Also
+          lzma_auto_decoder() supports .lz files.
+
+        - Building with --disable-threads --enable-small
+          is now thread-safe if the compiler supports
+          __attribute__((__constructor__))
+
+    * xz:
+
+        - Added support for OpenBSD's pledge(2) as a sandboxing method.
+
+        - Don't mention endianness for ARM and ARM-Thumb filters in
+          --long-help. The filters only work for little endian
+          instruction encoding but modern ARM processors using
+          big endian data access still use little endian
+          instruction encoding. So the help text was misleading.
+          In contrast, the PowerPC filter is only for big endian
+          32/64-bit PowerPC code. Little endian PowerPC would need
+          a separate filter.
+
+        - Added --experimental-arm64. This will be renamed once the
+          filter is finished. Files created with this experimental
+          filter will not be supported in the future!
+
+        - Added new fields to the output of xz --robot --info-memory.
+
+        - Added decompression support for the .lz (lzip) file format
+          version 0 and the original unextended version 1. It is
+          autodetected by default. See also the option --format on
+          the xz man page.
+
+    * Scripts now support the .lz format using xz.
+
+    * Build systems:
+
+        - New #defines in config.h: HAVE_ENCODER_ARM64,
+          HAVE_DECODER_ARM64, HAVE_LZIP_DECODER, HAVE_CPUID_H,
+          HAVE_FUNC_ATTRIBUTE_CONSTRUCTOR, HAVE_USABLE_CLMUL
+
+        - New configure options: --disable-clmul-crc,
+          --disable-microlzma, --disable-lzip-decoder, and
+          'pledge' is now an option in --enable-sandbox (but
+          it's autodetected by default anyway).
+
+        - INSTALL was updated to document the new configure options.
+
+        - PACKAGERS now lists also --disable-microlzma and
+          --disable-lzip-decoder as configure options that must
+          not be used in builds for non-embedded use.
+
+    * Tests:
+
+        - Fix some of the tests so that they skip instead of fail if
+          certain features have been disabled with configure options.
+          It's still not perfect.
+
+        - Other improvements to tests.
+
+    * Updated translations: Croatian, Finnish, Hungarian, Polish,
+      Romanian, Spanish, Swedish, and Ukrainian.
+
+
+5.3.3alpha (2022-08-22)
+
+    * All fixes from 5.2.6.
+
+    * liblzma:
+
+        - Fixed 32-bit build.
+
+        - Added threaded .xz decompressor lzma_stream_decoder_mt().
+          It can use multiple threads with .xz files that have multiple
+          Blocks with size information in Block Headers. The threaded
+          encoder in xz has always created such files.
+
+          Single-threaded encoder cannot store the size information in
+          Block Headers even if one used LZMA_FULL_FLUSH to create
+          multiple Blocks, so this threaded decoder cannot use multiple
+          threads with such files.
+
+          If there are multiple Streams (concatenated .xz files), one
+          Stream will be decompressed completely before starting the
+          next Stream.
+
+        - A new decoder flag LZMA_FAIL_FAST was added. It makes the
+          threaded decompressor report errors soon instead of first
+          flushing all pending data before the error location.
+
+    * xz:
+
+        - Using -T0 (--threads=0) will now use multi-threaded encoder
+          even on a single-core system. This is to ensure that output
+          from the same xz binary is identical on both single-core and
+          multi-core systems.
+
+        - A default soft memory usage limit is now used for compression
+          when -T0 is used and no explicit limit has been specified.
+          This soft limit is used to restrict the number of threads
+          but if the limit is exceeded with even one thread then xz
+          will continue with one thread using the multi-threaded
+          encoder and this limit is ignored. If the number of threads
+          is specified manually then no default limit will be used;
+          this affects only -T0.
+
+          This change helps on systems that have very many cores and
+          using all of them for xz makes no sense. Previously xz -T0
+          could run out of memory on such systems because it attempted
+          to reserve memory for too many threads.
+
+          This also helps with 32-bit builds which don't have a large
+          amount of address space that would be required for many
+          threads. The default limit is 1400 MiB on all 32-bit
+          platforms with -T0.
+
+          Now xz -T0 should just work. It might use too few threads
+          in some cases but at least it shouldn't easily run out of
+          memory. It's possible that this will be tweaked before 5.4.0.
+
+        - Changes to --memlimit-compress and --no-adjust:
+
+          In single-threaded mode, --memlimit-compress can make xz
+          scale down the LZMA2 dictionary size to meet the memory usage
+          limit. This obviously affects the compressed output. However,
+          if xz was in threaded mode, --memlimit-compress could make xz
+          reduce the number of threads but it wouldn't make xz switch
+          from multi-threaded mode to single-threaded mode or scale
+          down the LZMA2 dictionary size. This seemed illogical.
+
+          Now --memlimit-compress can make xz switch to single-threaded
+          mode if one thread in multi-threaded mode uses too much
+          memory. If memory usage is still too high, then the LZMA2
+          dictionary size can be scaled down too.
+
+          The option --no-adjust was also changed so that it no longer
+          prevents xz from scaling down the number of threads as that
+          doesn't affect compressed output (only performance). After
+          this commit --no-adjust only prevents adjustments that affect
+          compressed output, that is, with --no-adjust xz won't switch
+          from multithreaded mode to single-threaded mode and won't
+          scale down the LZMA2 dictionary size.
+
+        - Added a new option --memlimit-mt-decompress=LIMIT. This is
+          used to limit the number of decompressor threads (possibly
+          falling back to single-threaded mode) but it will never make
+          xz refuse to decompress a file. This has a system-specific
+          default value because without any limit xz could end up
+          allocating memory for the whole compressed input file, the
+          whole uncompressed output file, multiple thread-specific
+          decompressor instances and so on. Basically xz could
+          attempt to use an insane amount of memory even with fairly
+          common files.
+
+          The new option works together with the existing option
+          --memlimit-decompress=LIMIT. The old option sets a hard limit
+          that must not be exceeded (xz will refuse to decompress)
+          while the new option only restricts the number of threads.
+          If the limit set with --memlimit-mt-decompress is greater
+          than the limit set with --memlimit-compress, then the latter
+          value is used also for --memlimit-mt-decompress.
+
+    * Tests:
+
+        - Added a few more tests.
+
+        - Added tests/code_coverage.sh to create a code coverage report
+          of the tests.
+
+    * Build systems:
+
+        - Automake's parallel test harness is now used to make tests
+          finish faster.
+
+        - Added the CMake files to the distribution tarball. These were
+          supposed to be in 5.2.5 already.
+
+        - Added liblzma tests to the CMake build.
+
+        - Windows: Fix building of liblzma.dll with the included
+          Visual Studio project files.
+
+
+5.3.2alpha (2021-10-28)
+
+    This release was made on short notice so that recent erofs-utils can
+    be built with LZMA support without needing a snapshot from xz.git.
+    Thus many pending things were not included, not even updated
+    translations (which would need to be updated for the new --list
+    strings anyway).
+
+    * All fixes from 5.2.5.
+
+    * xz:
+
+        - When copying metadata from the source file to the destination
+          file, don't try to set the group (GID) if it is already set
+          correctly. This avoids a failure on OpenBSD (and possibly on
+          a few other OSes) where files may get created so that their
+          group doesn't belong to the user, and fchown(2) can fail even
+          if it needs to do nothing.
+
+        - The --keep option now accepts symlinks, hardlinks, and
+          setuid, setgid, and sticky files. Previously this required
+          using --force.
+
+        - Split the long strings used in --list and --info-memory modes
+          to make them much easier for translators.
+
+        - If built with sandbox support and enabling the sandbox fails,
+          xz will now immediately exit with exit status of 1. Previously
+          it would only display a warning if -vv was used.
+
+        - Cap --memlimit-compress to 2000 MiB on MIPS32 because on
+          MIPS32 userspace processes are limited to 2 GiB of address
+          space.
+
+    * liblzma:
+
+        - Added lzma_microlzma_encoder() and lzma_microlzma_decoder().
+          The API is in lzma/container.h.
+
+          The MicroLZMA format is a raw LZMA stream (without end marker)
+          whose first byte (always 0x00) has been replaced with
+          bitwise-negation of the LZMA properties (lc/lp/pb). It was
+          created for use in EROFS but may be used in other contexts
+          as well where it is important to avoid wasting bytes for
+          stream headers or footers. The format is also supported by
+          XZ Embedded.
+
+          The MicroLZMA encoder API in liblzma can compress into a
+          fixed-sized output buffer so that as much data is compressed
+          as can be fit into the buffer while still creating a valid
+          MicroLZMA stream. This is needed for EROFS.
+
+        - Added fuzzing support.
+
+        - Support Intel Control-flow Enforcement Technology (CET) in
+          32-bit x86 assembly files.
+
+        - Visual Studio: Use non-standard _MSVC_LANG to detect C++
+          standard version in the lzma.h API header. It's used to
+          detect when "noexcept" can be used.
+
+    * Scripts:
+
+        - Fix exit status of xzdiff/xzcmp. Exit status could be 2 when
+          the correct value is 1.
+
+        - Fix exit status of xzgrep.
+
+        - Detect corrupt .bz2 files in xzgrep.
+
+        - Add zstd support to xzgrep and xzdiff/xzcmp.
+
+        - Fix less(1) version detection in xzless. It failed if the
+          version number from "less -V" contained a dot.
+
+    * Fix typos and technical issues in man pages.
+
+    * Build systems:
+
+        - Windows: Fix building of resource files when config.h isn't
+          used. CMake + Visual Studio can now build liblzma.dll.
+
+        - Various fixes to the CMake support. It might still need a few
+          more fixes even for liblzma-only builds.
+
+
+5.3.1alpha (2018-04-29)
+
+    * All fixes from 5.2.4.
+
+    * Add lzma_file_info_decoder() into liblzma and use it in xz to
+      implement the --list feature.
+
+    * Capsicum sandbox support is enabled by default where available
+      (FreeBSD >= 10).
+
+
+5.2.10 (2022-12-13)
+
+    * xz: Don't modify argv[] when parsing the --memlimit* and
+      --block-list command line options. This fixes confusing
+      arguments in process listing (like "ps auxf").
+
+    * GNU/Linux only: Use __has_attribute(__symver__) to detect if
+      that attribute is supported. This fixes build on Mandriva where
+      Clang is patched to define __GNUC__ to 11 by default (instead
+      of 4 as used by Clang upstream).
+
+
+5.2.9 (2022-11-30)
+
+    * liblzma:
+
+        - Fixed an infinite loop in LZMA encoder initialization
+          if dict_size >= 2 GiB. (The encoder only supports up
+          to 1536 MiB.)
+
+        - Fixed two cases of invalid free() that can happen if
+          a tiny allocation fails in encoder re-initialization
+          or in lzma_filters_update(). These bugs had some
+          similarities with the bug fixed in 5.2.7.
+
+        - Fixed lzma_block_encoder() not allowing the use of
+          LZMA_SYNC_FLUSH with lzma_code() even though it was
+          documented to be supported. The sync-flush code in
+          the Block encoder was already used internally via
+          lzma_stream_encoder(), so this was just a missing flag
+          in the lzma_block_encoder() API function.
+
+        - GNU/Linux only: Don't put symbol versions into static
+          liblzma as it breaks things in some cases (and even if
+          it didn't break anything, symbol versions in static
+          libraries are useless anyway). The downside of the fix
+          is that if the configure options --with-pic or --without-pic
+          are used then it's not possible to build both shared and
+          static liblzma at the same time on GNU/Linux anymore;
+          with those options --disable-static or --disable-shared
+          must be used too.
+
+    * New email address for bug reports is <xz@tukaani.org> which
+      forwards messages to Lasse Collin and Jia Tan.
+
+
+5.2.8 (2022-11-13)
+
+    * xz:
+
+        - If xz cannot remove an input file when it should, this
+          is now treated as a warning (exit status 2) instead of
+          an error (exit status 1). This matches GNU gzip and it
+          is more logical as at that point the output file has
+          already been successfully closed.
+
+        - Fix handling of .xz files with an unsupported check type.
+          Previously such printed a warning message but then xz
+          behaved as if an error had occurred (didn't decompress,
+          exit status 1). Now a warning is printed, decompression
+          is done anyway, and exit status is 2. This used to work
+          slightly before 5.0.0. In practice this bug matters only
+          if xz has been built with some check types disabled. As
+          instructed in PACKAGERS, such builds should be done in
+          special situations only.
+
+        - Fix "xz -dc --single-stream tests/files/good-0-empty.xz"
+          which failed with "Internal error (bug)". That is,
+          --single-stream was broken if the first .xz stream in
+          the input file didn't contain any uncompressed data.
+
+        - Fix displaying file sizes in the progress indicator when
+          working in passthru mode and there are multiple input files.
+          Just like "gzip -cdf", "xz -cdf" works like "cat" when the
+          input file isn't a supported compressed file format. In
+          this case the file size counters weren't reset between
+          files so with multiple input files the progress indicator
+          displayed an incorrect (too large) value.
+
+    * liblzma:
+
+        - API docs in lzma/container.h:
+            * Update the list of decoder flags in the decoder
+              function docs.
+            * Explain LZMA_CONCATENATED behavior with .lzma files
+              in lzma_auto_decoder() docs.
+
+        - OpenBSD: Use HW_NCPUONLINE to detect the number of
+          available hardware threads in lzma_physmem().
+
+        - Fix use of wrong macro to detect x86 SSE2 support.
+          __SSE2_MATH__ was used with GCC/Clang but the correct
+          one is __SSE2__. The first one means that SSE2 is used
+          for floating point math which is irrelevant here.
+          The affected SSE2 code isn't used on x86-64 so this affects
+          only 32-bit x86 builds that use -msse2 without -mfpmath=sse
+          (there is no runtime detection for SSE2). It improves LZMA
+          compression speed (not decompression).
+
+        - Fix the build with Intel C compiler 2021 (ICC, not ICX)
+          on Linux. It defines __GNUC__ to 10 but doesn't support
+          the __symver__ attribute introduced in GCC 10.
+
+    * Scripts: Ignore warnings from xz by using --quiet --no-warn.
+      This is needed if the input .xz files use an unsupported
+      check type.
+
+    * Translations:
+
+        - Updated Croatian and Turkish translations.
+
+        - One new translations wasn't included because it needed
+          technical fixes. It will be in upcoming 5.4.0. No new
+          translations will be added to the 5.2.x branch anymore.
+
+        - Renamed the French man page translation file from
+          fr_FR.po to fr.po and thus also its install directory
+          (like /usr/share/man/fr_FR -> .../fr).
+
+        - Man page translations for upcoming 5.4.0 are now handled
+          in the Translation Project.
+
+    * Update doc/faq.txt a little so it's less out-of-date.
+
+
+5.2.7 (2022-09-30)
+
+    * liblzma:
+
+        - Made lzma_filters_copy() to never modify the destination
+          array if an error occurs. lzma_stream_encoder() and
+          lzma_stream_encoder_mt() already assumed this. Before this
+          change, if a tiny memory allocation in lzma_filters_copy()
+          failed it would lead to a crash (invalid free() or invalid
+          memory reads) in the cleanup paths of these two encoder
+          initialization functions.
+
+        - Added missing integer overflow check to lzma_index_append().
+          This affects xz --list and other applications that decode
+          the Index field from .xz files using lzma_index_decoder().
+          Normal decompression of .xz files doesn't call this code
+          and thus most applications using liblzma aren't affected
+          by this bug.
+
+        - Single-threaded .xz decoder (lzma_stream_decoder()): If
+          lzma_code() returns LZMA_MEMLIMIT_ERROR it is now possible
+          to use lzma_memlimit_set() to increase the limit and continue
+          decoding. This was supposed to work from the beginning
+          but there was a bug. With other decoders (.lzma or
+          threaded .xz decoder) this already worked correctly.
+
+        - Fixed accumulation of integrity check type statistics in
+          lzma_index_cat(). This bug made lzma_index_checks() return
+          only the type of the integrity check of the last Stream
+          when multiple lzma_indexes were concatenated. Most
+          applications don't use these APIs but in xz it made
+          xz --list not list all check types from concatenated .xz
+          files. In xz --list --verbose only the per-file "Check:"
+          lines were affected and in xz --robot --list only the "file"
+          line was affected.
+
+        - Added ABI compatibility with executables that were linked
+          against liblzma in RHEL/CentOS 7 or other liblzma builds
+          that had copied the problematic patch from RHEL/CentOS 7
+          (xz-5.2.2-compat-libs.patch). For the details, see the
+          comment at the top of src/liblzma/validate_map.sh.
+
+          WARNING: This uses __symver__ attribute with GCC >= 10.
+          In other cases the traditional __asm__(".symver ...")
+          is used. Using link-time optimization (LTO, -flto) with
+          GCC versions older than 10 can silently result in
+          broken liblzma.so.5 (incorrect symbol versions)! If you
+          want to use -flto with GCC, you must use GCC >= 10.
+          LTO with Clang seems to work even with the traditional
+          __asm__(".symver ...") method.
+
+    * xzgrep: Fixed compatibility with old shells that break if
+      comments inside command substitutions have apostrophes (').
+      This problem was introduced in 5.2.6.
+
+    * Build systems:
+
+        - New #define in config.h: HAVE_SYMBOL_VERSIONS_LINUX
+
+        - Windows: Fixed liblzma.dll build with Visual Studio project
+          files. It broke in 5.2.6 due to a change that was made to
+          improve CMake support.
+
+        - Windows: Building liblzma with UNICODE defined should now
+          work.
+
+        - CMake files are now actually included in the release tarball.
+          They should have been in 5.2.5 already.
+
+        - Minor CMake fixes and improvements.
+
+    * Added a new translation: Turkish
+
+
+5.2.6 (2022-08-12)
+
+    * xz:
+
+        - The --keep option now accepts symlinks, hardlinks, and
+          setuid, setgid, and sticky files. Previously this required
+          using --force.
+
+        - When copying metadata from the source file to the destination
+          file, don't try to set the group (GID) if it is already set
+          correctly. This avoids a failure on OpenBSD (and possibly on
+          a few other OSes) where files may get created so that their
+          group doesn't belong to the user, and fchown(2) can fail even
+          if it needs to do nothing.
+
+        - Cap --memlimit-compress to 2000 MiB instead of 4020 MiB on
+          MIPS32 because on MIPS32 userspace processes are limited
+          to 2 GiB of address space.
+
+    * liblzma:
+
+        - Fixed a missing error-check in the threaded encoder. If a
+          small memory allocation fails, a .xz file with an invalid
+          Index field would be created. Decompressing such a file would
+          produce the correct output but result in an error at the end.
+          Thus this is a "mild" data corruption bug. Note that while
+          a failed memory allocation can trigger the bug, it cannot
+          cause invalid memory access.
+
+        - The decoder for .lzma files now supports files that have
+          uncompressed size stored in the header and still use the
+          end of payload marker (end of stream marker) at the end
+          of the LZMA stream. Such files are rare but, according to
+          the documentation in LZMA SDK, they are valid.
+          doc/lzma-file-format.txt was updated too.
+
+        - Improved 32-bit x86 assembly files:
+            * Support Intel Control-flow Enforcement Technology (CET)
+            * Use non-executable stack on FreeBSD.
+
+        - Visual Studio: Use non-standard _MSVC_LANG to detect C++
+          standard version in the lzma.h API header. It's used to
+          detect when "noexcept" can be used.
+
+    * xzgrep:
+
+        - Fixed arbitrary command injection via a malicious filename
+          (CVE-2022-1271, ZDI-CAN-16587). A standalone patch for
+          this was released to the public on 2022-04-07. A slight
+          robustness improvement has been made since then and, if
+          using GNU or *BSD grep, a new faster method is now used
+          that doesn't use the old sed-based construct at all. This
+          also fixes bad output with GNU grep >= 3.5 (2020-09-27)
+          when xzgrepping binary files.
+
+          This vulnerability was discovered by:
+          cleemy desu wayo working with Trend Micro Zero Day Initiative
+
+        - Fixed detection of corrupt .bz2 files.
+
+        - Improved error handling to fix exit status in some situations
+          and to fix handling of signals: in some situations a signal
+          didn't make xzgrep exit when it clearly should have. It's
+          possible that the signal handling still isn't quite perfect
+          but hopefully it's good enough.
+
+        - Documented exit statuses on the man page.
+
+        - xzegrep and xzfgrep now use "grep -E" and "grep -F" instead
+          of the deprecated egrep and fgrep commands.
+
+        - Fixed parsing of the options -E, -F, -G, -P, and -X. The
+          problem occurred when multiple options were specified in
+          a single argument, for example,
+
+              echo foo | xzgrep -Fe foo
+
+          treated foo as a filename because -Fe wasn't correctly
+          split into -F -e.
+
+        - Added zstd support.
+
+    * xzdiff/xzcmp:
+
+        - Fixed wrong exit status. Exit status could be 2 when the
+          correct value is 1.
+
+        - Documented on the man page that exit status of 2 is used
+          for decompression errors.
+
+        - Added zstd support.
+
+    * xzless:
+
+        - Fix less(1) version detection. It failed if the version number
+          from "less -V" contained a dot.
+
+    * Translations:
+
+        - Added new translations: Catalan, Croatian, Esperanto,
+          Korean, Portuguese, Romanian, Serbian, Spanish, Swedish,
+          and Ukrainian
+
+        - Updated the Brazilian Portuguese translation.
+
+        - Added French man page translation. This and the existing
+          German translation aren't complete anymore because the
+          English man pages got a few updates and the translators
+          weren't reached so that they could update their work.
+
+    * Build systems:
+
+        - Windows: Fix building of resource files when config.h isn't
+          used. CMake + Visual Studio can now build liblzma.dll.
+
+        - Various fixes to the CMake support. Building static or shared
+          liblzma should work fine in most cases. In contrast, building
+          the command line tools with CMake is still clearly incomplete
+          and experimental and should be used for testing only.
+
+
+5.2.5 (2020-03-17)
+
+    * liblzma:
+
+        - Fixed several C99/C11 conformance bugs. Now the code is clean
+          under gcc/clang -fsanitize=undefined. Some of these changes
+          might have a negative effect on performance with old GCC
+          versions or compilers other than GCC and Clang. The configure
+          option --enable-unsafe-type-punning can be used to (mostly)
+          restore the old behavior but it shouldn't normally be used.
+
+        - Improved API documentation of lzma_properties_decode().
+
+        - Added a very minor encoder speed optimization.
+
+    * xz:
+
+        - Fixed a crash in "xz -dcfv not_an_xz_file". All four options
+          were required to trigger it. The crash occurred in the
+          progress indicator code when xz was in passthru mode where
+          xz works like "cat".
+
+        - Fixed an integer overflow with 32-bit off_t. It could happen
+          when decompressing a file that has a long run of zero bytes
+          which xz would try to write as a sparse file. Since the build
+          system enables large file support by default, off_t is
+          normally 64-bit even on 32-bit systems.
+
+        - Fixes for --flush-timeout:
+            * Fix semi-busy-waiting.
+            * Avoid unneeded flushes when no new input has arrived
+              since the previous flush was completed.
+
+        - Added a special case for 32-bit xz: If --memlimit-compress is
+          used to specify a limit that exceeds 4020 MiB, the limit will
+          be set to 4020 MiB. The values "0" and "max" aren't affected
+          by this and neither is decompression. This hack can be
+          helpful when a 32-bit xz has access to 4 GiB address space
+          but the specified memlimit exceeds 4 GiB. This can happen
+          e.g. with some scripts.
+
+        - Capsicum sandbox is now enabled by default where available
+          (FreeBSD >= 10). The sandbox debug messages (xz -vv) were
+          removed since they seemed to be more annoying than useful.
+
+        - DOS build now requires DJGPP 2.05 instead of 2.04beta.
+          A workaround for a locale problem with DJGPP 2.05 was added.
+
+    * xzgrep and other scripts:
+
+        - Added a configure option --enable-path-for-scripts=PREFIX.
+          It is disabled by default except on Solaris where the default
+          is /usr/xpg4/bin. See INSTALL for details.
+
+        - Added a workaround for a POSIX shell detection problem on
+          Solaris.
+
+    * Build systems:
+
+        - Added preliminary build instructions for z/OS. See INSTALL
+          section 1.2.9.
+
+        - Experimental CMake support was added. It should work to build
+          static liblzma on a few operating systems. It may or may not
+          work to build shared liblzma. On some platforms it can build
+          xz and xzdec too but those are only for testing. See the
+          comment in the beginning of CMakeLists.txt for details.
+
+        - Visual Studio project files were updated.
+          WindowsTargetPlatformVersion was removed from VS2017 files
+          and set to "10.0" in the added VS2019 files. In the future
+          the VS project files will be removed when CMake support is
+          good enough.
+
+        - New #defines in config.h: HAVE___BUILTIN_ASSUME_ALIGNED,
+          HAVE___BUILTIN_BSWAPXX, and TUKLIB_USE_UNSAFE_TYPE_PUNNING.
+
+        - autogen.sh has a new optional dependency on po4a and a new
+          option --no-po4a to skip that step. This matters only if one
+          wants to remake the build files. po4a is used to update the
+          translated man pages but as long as the man pages haven't
+          been modified, there's nothing to update and one can use
+          --no-po4a to avoid the dependency on po4a.
+
+    * Translations:
+
+        - XZ Utils translations are now handled by the Translation
+          Project: https://translationproject.org/domain/xz.html
+
+        - All man pages are now included in German too.
+
+        - New xz translations: Brazilian Portuguese, Finnish,
+          Hungarian, Chinese (simplified), Chinese (traditional),
+          and Danish (partial translation)
+
+        - Updated xz translations: French, German, Italian, and Polish
+
+        - Unfortunately a few new xz translations weren't included due
+          to technical problems like too long lines in --help output or
+          misaligned column headings in tables. In the future, many of
+          these strings will be split and e.g. the table column
+          alignment will be handled in software. This should make the
+          strings easier to translate.
+
+
+5.2.4 (2018-04-29)
+
+    * liblzma:
+
+        - Allow 0 as memory usage limit instead of returning
+          LZMA_PROG_ERROR. Now 0 is treated as if 1 byte was specified,
+          which effectively is the same as 0.
+
+        - Use "noexcept" keyword instead of "throw()" in the public
+          headers when a C++11 (or newer standard) compiler is used.
+
+        - Added a portability fix for recent Intel C Compilers.
+
+        - Microsoft Visual Studio build files have been moved under
+          windows/vs2013 and windows/vs2017.
+
+    * xz:
+
+        - Fix "xz --list --robot missing_or_bad_file.xz" which would
+          try to print an uninitialized string and thus produce garbage
+          output. Since the exit status is non-zero, most uses of such
+          a command won't try to interpret the garbage output.
+
+        - "xz --list foo.xz" could print "Internal error (bug)" in a
+          corner case where a specific memory usage limit had been set.
+
+
+5.2.3 (2016-12-30)
+
+    * xz:
+
+        - Always close a file before trying to delete it to avoid
+          problems on some operating system and file system combinations.
+
+        - Fixed copying of file timestamps on Windows.
+
+        - Added experimental (disabled by default) sandbox support using
+          Capsicum (FreeBSD >= 10). See --enable-sandbox in INSTALL.
+
+    * C99/C11 conformance fixes to liblzma. The issues affected at least
+      some builds using link-time optimizations.
+
+    * Fixed bugs in the rarely-used function lzma_index_dup().
+
+    * Use of external SHA-256 code is now disabled by default.
+      It can still be enabled by passing --enable-external-sha256
+      to configure. The reasons to disable it by default (see INSTALL
+      for more details):
+
+        - Some OS-specific SHA-256 implementations conflict with
+          OpenSSL and cause problems in programs that link against both
+          liblzma and libcrypto. At least FreeBSD 10 and MINIX 3.3.0
+          are affected.
+
+        - The internal SHA-256 is faster than the SHA-256 code in
+          some operating systems.
+
+    * Changed CPU core count detection to use sched_getaffinity() on
+      GNU/Linux and GNU/kFreeBSD.
+
+    * Fixes to the build-system and xz to make xz buildable even when
+      encoders, decoders, or threading have been disabled from libilzma
+      using configure options. These fixes added two new #defines to
+      config.h: HAVE_ENCODERS and HAVE_DECODERS.
+
+
+5.2.2 (2015-09-29)
+
+    * Fixed bugs in QNX-specific code.
+
+    * Omitted the use of pipe2() even if it is available to avoid
+      portability issues with some old Linux and glibc combinations.
+
+    * Updated German translation.
+
+    * Added project files to build static and shared liblzma (not the
+      whole XZ Utils) with Visual Studio 2013 update 2 or later.
+
+    * Documented that threaded decompression hasn't been implemented
+      yet. A 5.2.0 NEWS entry describing multi-threading support had
+      incorrectly said "decompression" when it should have said
+      "compression".
+
+
+5.2.1 (2015-02-26)
+
+    * Fixed a compression-ratio regression in fast mode of LZMA1 and
+      LZMA2. The bug is present in 5.1.4beta and 5.2.0 releases.
+
+    * Fixed a portability problem in xz that affected at least OpenBSD.
+
+    * Fixed xzdiff to be compatible with FreeBSD's mktemp which differs
+      from most other mktemp implementations.
+
+    * Changed CPU core count detection to use cpuset_getaffinity() on
+      FreeBSD.
+
+
+5.2.0 (2014-12-21)
+
+    Since 5.1.4beta:
+
+    * All fixes from 5.0.8
+
+    * liblzma: Fixed lzma_stream_encoder_mt_memusage() when a preset
+      was used.
+
+    * xzdiff: If mktemp isn't installed, mkdir will be used as
+      a fallback to create a temporary directory. Installing mktemp
+      is still recommended.
+
+    * Updated French, German, Italian, Polish, and Vietnamese
+      translations.
+
+    Summary of fixes and new features added in the 5.1.x development
+    releases:
+
+    * liblzma:
+
+        - Added support for multi-threaded compression. See the
+          lzma_mt structure, lzma_stream_encoder_mt(), and
+          lzma_stream_encoder_mt_memusage() in <lzma/container.h>,
+          lzma_get_progress() in <lzma/base.h>, and lzma_cputhreads()
+          in <lzma/hardware.h> for details.
+
+        - Made the uses of lzma_allocator const correct.
+
+        - Added lzma_block_uncomp_encode() to create uncompressed
+          .xz Blocks using LZMA2 uncompressed chunks.
+
+        - Added support for LZMA_IGNORE_CHECK.
+
+        - A few speed optimizations were made.
+
+        - Added support for symbol versioning. It is enabled by default
+          on GNU/Linux, other GNU-based systems, and FreeBSD.
+
+        - liblzma (not the whole XZ Utils) should now be buildable
+          with MSVC 2013 update 2 or later using windows/config.h.
+
+    * xz:
+
+        - Fixed a race condition in the signal handling. It was
+          possible that e.g. the first SIGINT didn't make xz exit
+          if reading or writing blocked and one had bad luck. The fix
+          is non-trivial, so as of writing it is unknown if it will be
+          backported to the v5.0 branch.
+
+        - Multi-threaded compression can be enabled with the
+          --threads (-T) option.
+          [Fixed: This originally said "decompression".]
+
+        - New command line options in xz: --single-stream,
+          --block-size=SIZE, --block-list=SIZES,
+          --flush-timeout=TIMEOUT, and --ignore-check.
+
+        - xz -lvv now shows the minimum xz version that is required to
+          decompress the file. Currently it is 5.0.0 for all supported
+          .xz files except files with empty LZMA2 streams require 5.0.2.
+
+    * xzdiff and xzgrep now support .lzo files if lzop is installed.
+      The .tzo suffix is also recognized as a shorthand for .tar.lzo.
+
+
+5.1.4beta (2014-09-14)
+
+    * All fixes from 5.0.6
+
+    * liblzma: Fixed the use of presets in threaded encoder
+      initialization.
+
+    * xz --block-list and --block-size can now be used together
+      in single-threaded mode. Previously the combination only
+      worked in multi-threaded mode.
+
+    * Added support for LZMA_IGNORE_CHECK to liblzma and made it
+      available in xz as --ignore-check.
+
+    * liblzma speed optimizations:
+
+        - Initialization of a new LZMA1 or LZMA2 encoder has been
+          optimized. (The speed of reinitializing an already-allocated
+          encoder isn't affected.) This helps when compressing many
+          small buffers with lzma_stream_buffer_encode() and other
+          similar situations where an already-allocated encoder state
+          isn't reused. This speed-up is visible in xz too if one
+          compresses many small files one at a time instead running xz
+          once and giving all files as command-line arguments.
+
+        - Buffer comparisons are now much faster when unaligned access
+          is allowed (configured with --enable-unaligned-access). This
+          speeds up encoding significantly. There is arch-specific code
+          for 32-bit and 64-bit x86 (32-bit needs SSE2 for the best
+          results and there's no run-time CPU detection for now).
+          For other archs there is only generic code which probably
+          isn't as optimal as arch-specific solutions could be.
+
+        - A few speed optimizations were made to the SHA-256 code.
+          (Note that the builtin SHA-256 code isn't used on all
+          operating systems.)
+
+    * liblzma can now be built with MSVC 2013 update 2 or later
+      using windows/config.h.
+
+    * Vietnamese translation was added.
+
+
+5.1.3alpha (2013-10-26)
+
+    * All fixes from 5.0.5
+
+    * liblzma:
+
+        - Fixed a deadlock in the threaded encoder.
+
+        - Made the uses of lzma_allocator const correct.
+
+        - Added lzma_block_uncomp_encode() to create uncompressed
+          .xz Blocks using LZMA2 uncompressed chunks.
+
+        - Added support for native threads on Windows and the ability
+          to detect the number of CPU cores.
+
+    * xz:
+
+        - Fixed a race condition in the signal handling. It was
+          possible that e.g. the first SIGINT didn't make xz exit
+          if reading or writing blocked and one had bad luck. The fix
+          is non-trivial, so as of writing it is unknown if it will be
+          backported to the v5.0 branch.
+
+        - Made the progress indicator work correctly in threaded mode.
+
+        - Threaded encoder now works together with --block-list=SIZES.
+
+        - Added preliminary support for --flush-timeout=TIMEOUT.
+          It can be useful for (somewhat) real-time streaming. For
+          now the decompression side has to be done with something
+          else than the xz tool due to how xz does buffering, but this
+          should be fixed.
+
+
+5.1.2alpha (2012-07-04)
+
+    * All fixes from 5.0.3 and 5.0.4
+
+    * liblzma:
+
+        - Fixed a deadlock and an invalid free() in the threaded encoder.
+
+        - Added support for symbol versioning. It is enabled by default
+          on GNU/Linux, other GNU-based systems, and FreeBSD.
+
+        - Use SHA-256 implementation from the operating system if one is
+          available in libc, libmd, or libutil. liblzma won't use e.g.
+          OpenSSL or libgcrypt to avoid introducing new dependencies.
+
+        - Fixed liblzma.pc for static linking.
+
+        - Fixed a few portability bugs.
+
+    * xz --decompress --single-stream now fixes the input position after
+      successful decompression. Now the following works:
+
+          echo foo | xz > foo.xz
+          echo bar | xz >> foo.xz
+          ( xz -dc --single-stream ; xz -dc --single-stream ) < foo.xz
+
+      Note that it doesn't work if the input is not seekable
+      or if there is Stream Padding between the concatenated
+      .xz Streams.
+
+    * xz -lvv now shows the minimum xz version that is required to
+      decompress the file. Currently it is 5.0.0 for all supported .xz
+      files except files with empty LZMA2 streams require 5.0.2.
+
+    * Added an *incomplete* implementation of --block-list=SIZES to xz.
+      It only works correctly in single-threaded mode and when
+      --block-size isn't used at the same time. --block-list allows
+      specifying the sizes of Blocks which can be useful e.g. when
+      creating files for random-access reading.
+
+
+5.1.1alpha (2011-04-12)
+
+    * All fixes from 5.0.2
+
+    * liblzma fixes that will also be included in 5.0.3:
+
+        - A memory leak was fixed.
+
+        - lzma_stream_buffer_encode() no longer creates an empty .xz
+          Block if encoding an empty buffer. Such an empty Block with
+          LZMA2 data would trigger a bug in 5.0.1 and older (see the
+          first bullet point in 5.0.2 notes). When releasing 5.0.2,
+          I thought that no encoder creates this kind of files but
+          I was wrong.
+
+        - Validate function arguments better in a few functions. Most
+          importantly, specifying an unsupported integrity check to
+          lzma_stream_buffer_encode() no longer creates a corrupt .xz
+          file. Probably no application tries to do that, so this
+          shouldn't be a big problem in practice.
+
+        - Document that lzma_block_buffer_encode(),
+          lzma_easy_buffer_encode(), lzma_stream_encoder(), and
+          lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK.
+
+        - The return values of the _memusage() functions are now
+          documented better.
+
+    * Support for multithreaded compression was added using the simplest
+      method, which splits the input data into blocks and compresses
+      them independently. Other methods will be added in the future.
+      The current method has room for improvement, e.g. it is possible
+      to reduce the memory usage.
+
+    * Added the options --single-stream and --block-size=SIZE to xz.
+
+    * xzdiff and xzgrep now support .lzo files if lzop is installed.
+      The .tzo suffix is also recognized as a shorthand for .tar.lzo.
+
+    * Support for short 8.3 filenames under DOS was added to xz. It is
+      experimental and may change before it gets into a stable release.
+
+
+5.0.8 (2014-12-21)
+
+    * Fixed an old bug in xzgrep that affected OpenBSD and probably
+      a few other operating systems too.
+
+    * Updated French and German translations.
+
+    * Added support for detecting the amount of RAM on AmigaOS/AROS.
+
+    * Minor build system updates.
+
+
+5.0.7 (2014-09-20)
+
+    * Fix regressions introduced in 5.0.6:
+
+        - Fix building with non-GNU make.
+
+        - Fix invalid Libs.private value in liblzma.pc which broke
+          static linking against liblzma if the linker flags were
+          taken from pkg-config.
+
+
+5.0.6 (2014-09-14)
+
+    * xzgrep now exits with status 0 if at least one file matched.
+
+    * A few minor portability and build system fixes
+
+
+5.0.5 (2013-06-30)
+
+    * lzmadec and liblzma's lzma_alone_decoder(): Support decompressing
+      .lzma files that have less common settings in the headers
+      (dictionary size other than 2^n or 2^n + 2^(n-1), or uncompressed
+      size greater than 256 GiB). The limitations existed to avoid false
+      positives when detecting .lzma files. The lc + lp <= 4 limitation
+      still remains since liblzma's LZMA decoder has that limitation.
+
+      NOTE: xz's .lzma support or liblzma's lzma_auto_decoder() are NOT
+      affected by this change. They still consider uncommon .lzma headers
+      as not being in the .lzma format. Changing this would give way too
+      many false positives.
+
+    * xz:
+
+        - Interaction of preset and custom filter chain options was
+          made less illogical. This affects only certain less typical
+          uses cases so few people are expected to notice this change.
+
+          Now when a custom filter chain option (e.g. --lzma2) is
+          specified, all preset options (-0 ... -9, -e) earlier are on
+          the command line are completely forgotten. Similarly, when
+          a preset option is specified, all custom filter chain options
+          earlier on the command line are completely forgotten.
+
+          Example 1: "xz -9 --lzma2=preset=5 -e" is equivalent to "xz -e"
+          which is equivalent to "xz -6e". Earlier -e didn't put xz back
+          into preset mode and thus the example command was equivalent
+          to "xz --lzma2=preset=5".
+
+          Example 2: "xz -9e --lzma2=preset=5 -7" is equivalent to
+          "xz -7". Earlier a custom filter chain option didn't make
+          xz forget the -e option so the example was equivalent to
+          "xz -7e".
+
+        - Fixes and improvements to error handling.
+
+        - Various fixes to the man page.
+
+    * xzless: Fixed to work with "less" versions 448 and later.
+
+    * xzgrep: Made -h an alias for --no-filename.
+
+    * Include the previously missing debug/translation.bash which can
+      be useful for translators.
+
+    * Include a build script for Mac OS X. This has been in the Git
+      repository since 2010 but due to a mistake in Makefile.am the
+      script hasn't been included in a release tarball before.
+
+
+5.0.4 (2012-06-22)
+
+    * liblzma:
+
+        - Fix lzma_index_init(). It could crash if memory allocation
+          failed.
+
+        - Fix the possibility of an incorrect LZMA_BUF_ERROR when a BCJ
+          filter is used and the application only provides exactly as
+          much output space as is the uncompressed size of the file.
+
+        - Fix a bug in doc/examples_old/xz_pipe_decompress.c. It didn't
+          check if the last call to lzma_code() really returned
+          LZMA_STREAM_END, which made the program think that truncated
+          files are valid.
+
+        - New example programs in doc/examples (old programs are now in
+          doc/examples_old). These have more comments and more detailed
+          error handling.
+
+    * Fix "xz -lvv foo.xz". It could crash on some corrupted files.
+
+    * Fix output of "xz --robot -lv" and "xz --robot -lvv" which
+      incorrectly printed the filename also in the "foo (x/x)" format.
+
+    * Fix exit status of "xzdiff foo.xz bar.xz".
+
+    * Fix exit status of "xzgrep foo binary_file".
+
+    * Fix portability to EBCDIC systems.
+
+    * Fix a configure issue on AIX with the XL C compiler. See INSTALL
+      for details.
+
+    * Update French, German, Italian, and Polish translations.
+
+
+5.0.3 (2011-05-21)
+
+    * liblzma fixes:
+
+        - A memory leak was fixed.
+
+        - lzma_stream_buffer_encode() no longer creates an empty .xz
+          Block if encoding an empty buffer. Such an empty Block with
+          LZMA2 data would trigger a bug in 5.0.1 and older (see the
+          first bullet point in 5.0.2 notes). When releasing 5.0.2,
+          I thought that no encoder creates this kind of files but
+          I was wrong.
+
+        - Validate function arguments better in a few functions. Most
+          importantly, specifying an unsupported integrity check to
+          lzma_stream_buffer_encode() no longer creates a corrupt .xz
+          file. Probably no application tries to do that, so this
+          shouldn't be a big problem in practice.
+
+        - Document that lzma_block_buffer_encode(),
+          lzma_easy_buffer_encode(), lzma_stream_encoder(), and
+          lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK.
+
+        - The return values of the _memusage() functions are now
+          documented better.
+
+    * Fix command name detection in xzgrep. xzegrep and xzfgrep now
+      correctly use egrep and fgrep instead of grep.
+
+    * French translation was added.
+
+
+5.0.2 (2011-04-01)
+
+    * LZMA2 decompressor now correctly accepts LZMA2 streams with no
+      uncompressed data. Previously it considered them corrupt. The
+      bug can affect applications that use raw LZMA2 streams. It is
+      very unlikely to affect .xz files because no compressor creates
+      .xz files with empty LZMA2 streams. (Empty .xz files are a
+      different thing than empty LZMA2 streams.)
+
+    * "xz --suffix=.foo filename.foo" now refuses to compress the
+      file due to it already having the suffix .foo. It was already
+      documented on the man page, but the code lacked the test.
+
+    * "xzgrep -l foo bar.xz" works now.
+
+    * Polish translation was added.
+
+
+5.0.1 (2011-01-29)
+
+    * xz --force now (de)compresses files that have setuid, setgid,
+      or sticky bit set and files that have multiple hard links.
+      The man page had it documented this way already, but the code
+      had a bug.
+
+    * gzip and bzip2 support in xzdiff was fixed.
+
+    * Portability fixes
+
+    * Minor fix to Czech translation
+
+
+5.0.0 (2010-10-23)
+
+    Only the most important changes compared to 4.999.9beta are listed
+    here. One change is especially important:
+
+      * The memory usage limit is now disabled by default. Some scripts
+        written before this change may have used --memory=max on xz command
+        line or in XZ_OPT. THESE USES OF --memory=max SHOULD BE REMOVED
+        NOW, because they interfere with user's ability to set the memory
+        usage limit himself. If user-specified limit causes problems to
+        your script, blame the user.
+
+    Other significant changes:
+
+      * Added support for XZ_DEFAULTS environment variable. This variable
+        allows users to set default options for xz, e.g. default memory
+        usage limit or default compression level. Scripts that use xz
+        must never set or unset XZ_DEFAULTS. Scripts should use XZ_OPT
+        instead if they need a way to pass options to xz via an
+        environment variable.
+
+      * The compression settings associated with the preset levels
+        -0 ... -9 have been changed. --extreme was changed a little too.
+        It is now less likely to make compression worse, but with some
+        files the new --extreme may compress slightly worse than the old
+        --extreme.
+
+      * If a preset level (-0 ... -9) is specified after a custom filter
+        chain options have been used (e.g. --lzma2), the custom filter
+        chain will be forgotten. Earlier the preset options were
+        completely ignored after custom filter chain options had been
+        seen.
+
+      * xz will create sparse files when decompressing if the uncompressed
+        data contains long sequences of binary zeros. This is done even
+        when writing to standard output that is connected to a regular
+        file and certain additional conditions are met to make it safe.
+
+      * Support for "xz --list" was added. Combine with --verbose or
+        --verbose --verbose (-vv) for detailed output.
+
+      * I had hoped that liblzma API would have been stable after
+        4.999.9beta, but there have been a couple of changes in the
+        advanced features, which don't affect most applications:
+
+          - Index handling code was revised. If you were using the old
+            API, you will get a compiler error (so it's easy to notice).
+
+          - A subtle but important change was made to the Block handling
+            API. lzma_block.version has to be initialized even for
+            lzma_block_header_decode(). Code that doesn't do it will work
+            for now, but might break in the future, which makes this API
+            change easy to miss.
+
+      * The major soname has been bumped to 5.0.0. liblzma API and ABI
+        are now stable, so the need to recompile programs linking against
+        liblzma shouldn't arise soon.

+
+0. Preface
+----------
+
+    This document is meant for people who create and maintain XZ Utils
+    packages for operating system distributions. The focus is on GNU/Linux
+    systems, but most things apply to other systems too.
+
+    While the standard "configure && make DESTDIR=$PKG install" should
+    give a pretty good package, there are some details which packagers
+    may want to tweak.
+
+    Packagers should also read the INSTALL file.
+
+
+1. Package naming
+-----------------
+
+    The preferred name for the XZ Utils package is "xz", because that's
+    the name of the upstream tarball. Naturally you may have good reasons
+    to use some other name; I won't get angry about it. ;-) It's just nice
+    to be able to point people to the correct package name without asking
+    what distro they have.
+
+    If your distro policy is to split things into small pieces, here is
+    one suggestion:
+
+        xz              xz, xzdec, scripts (xzdiff, xzgrep, etc.), docs
+        xz-lzma         lzma, unlzma, lzcat, lzgrep etc. symlinks and
+                        lzmadec binary for compatibility with LZMA Utils
+        liblzma         liblzma.so.*
+        liblzma-devel   liblzma.so, liblzma.a, API headers
+        liblzma-doc     Doxygen-generated liblzma API docs (HTML),
+                        example programs
+
+
+2. Package description
+----------------------
+
+    Here is a suggestion which you may use as the package description.
+    If you can use only one-line description, pick only the first line.
+    Naturally, feel free to use some other description if you find it
+    better, and maybe send it to me too.
+
+        Library and command line tools for XZ and LZMA compressed files
+
+        XZ Utils provide a general purpose data compression library
+        and command line tools. The native file format is the .xz
+        format, but also the legacy .lzma format is supported. The .xz
+        format supports multiple compression algorithms, of which LZMA2
+        is currently the primary algorithm. With typical files, XZ Utils
+        create about 30 % smaller files than gzip.
+
+    If you are splitting XZ Utils into multiple packages, here are some
+    suggestions for package descriptions:
+
+    xz:
+
+        Command line tools for XZ and LZMA compressed files
+
+        This package includes the xz compression tool and other command
+        line tools from XZ Utils. xz has command line syntax similar to
+        that of gzip. The native file format is the .xz format, but also
+        the legacy .lzma format is supported. The .xz format supports
+        multiple compression algorithms, of which LZMA2 is currently the
+        primary algorithm. With typical files, XZ Utils create about 30 %
+        smaller files than gzip.
+
+        Note that this package doesn't include the files needed for
+        LZMA Utils 4.32.x compatibility. Install also the xz-lzma
+        package to make XZ Utils emulate LZMA Utils 4.32.x.
+
+    xz-lzma:
+
+        LZMA Utils emulation with XZ Utils
+
+        This package includes executables and symlinks to make
+        XZ Utils emulate lzma, unlzma, lzcat, and other command
+        line tools found from the legacy LZMA Utils 4.32.x package.
+
+    liblzma:
+
+        Library for XZ and LZMA compressed files
+
+        liblzma is a general purpose data compression library with
+        an API similar to that of zlib. liblzma supports multiple
+        algorithms, of which LZMA2 is currently the primary algorithm.
+        The native file format is .xz, but also the legacy .lzma
+        format and raw streams (no headers at all) are supported.
+
+        This package includes the shared library.
+
+    liblzma-devel:
+
+        Library for XZ and LZMA compressed files
+
+        This package includes the API headers, static library, and
+        other development files related to liblzma.
+
+    liblzma-doc:
+
+        liblzma API documentation in HTML and example usage
+
+        This package includes the Doxygen-generated liblzma API
+        HTML docs and example programs showing how to use liblzma.
+
+
+3. License
+----------
+
+    If the package manager supports a license field, you probably should
+    put GPLv2+ there (GNU GPL v2 or later). The interesting parts of
+    XZ Utils are in the public domain, but some less important files
+    ending up into the binary package are under GPLv2+. So it is simplest
+    to just say GPLv2+ if you cannot specify "public domain and GPLv2+".
+
+    If you split XZ Utils into multiple packages as described earlier
+    in this file, liblzma and liblzma-dev packages will contain only
+    public domain code (from XZ Utils at least; compiler or linker may
+    add some third-party code, which may be copyrighted).
+
+
+4. configure options
+--------------------
+
+    Unless you are building a package for a distribution that is meant
+    only for embedded systems, don't use the following configure options:
+
+        --enable-debug
+        --enable-encoders (*)
+        --enable-decoders
+        --enable-match-finders
+        --enable-checks
+        --enable-small (*)
+        --disable-threads (*)
+        --disable-microlzma (*)
+        --disable-lzip-decoder (*)
+
+    (*) These are OK when building xzdec and lzmadec as described
+        in INSTALL.
+
+    xzdec and lzmadec don't provide any functionality that isn't already
+    available in the xz tool. Shipping xzdec and lzmadec without size
+    optimization and statically-linked liblzma isn't very useful. Doing
+    that would give users the xzdec man page, which may make it easier
+    for people to find out that such tools exists, but the executables
+    wouldn't have any advantage over the full-featured xz.
+
+
+5. Additional documentation
+---------------------------
+
+    "make install" copies some additional documentation to $docdir
+    (--docdir in configure). There is a copy of the GNU GPL v2, which
+    can be replaced with a symlink if your distro ships with shared
+    copies of the common license texts.
+
+    The Doxygen-generated documentation (HTML) for the liblzma API
+    headers is included in the source release and will be installed by
+    "make install" to $docdir/api. All JavaScript is removed to
+    simplify license compliance and to reduce the install size. If the
+    liblzma API documentation is not desired, either run configure with
+    --disable-doc or remove the doc/api directory before running
+    "make install".
+
+
+6. Extra files
+--------------
+
+    The "extra" directory contains some small extra tools or other files.
+    The exact set of extra files can vary between XZ Utils releases. The
+    extra files have only limited use or they are too dangerous to be
+    put directly to $bindir (7z2lzma.sh is a good example, since it can
+    silently create corrupt output if certain conditions are not met).
+
+    If you feel like it, you may copy the extra directory under the doc
+    directory (e.g. /usr/share/doc/xz/extra). Maybe some people will find
+    them useful. However, most people needing these tools probably are
+    able to find them from the source package too.
+
+    The "debug" directory contains some tools that are useful only when
+    hacking on XZ Utils. Don't package these tools.
+
+
+7. Installing XZ Utils and LZMA Utils in parallel
+-------------------------------------------------
+
+    XZ Utils and LZMA Utils 4.32.x can be installed in parallel by
+    omitting the compatibility symlinks (lzma, unlzma, lzcat, lzgrep etc.)
+    from the XZ Utils package. It's probably a good idea to still package
+    the symlinks into a separate package so that users may choose if they
+    want to use XZ Utils or LZMA Utils for handling .lzma files.
+
+
+8. Example
+----------
+
+    Here is an example for i686 GNU/Linux that
+      - links xz and lzmainfo against shared liblzma;
+      - links size-optimized xzdec and lzmadec against static liblzma
+        while avoiding libpthread dependency;
+      - includes only shared liblzma in the final package; and
+      - copies also the "extra" directory to the package.
+
+    PKG=/tmp/xz-pkg
+    tar xf xz-x.y.z.tar.gz
+    cd xz-x.y.z
+    ./configure \
+            --prefix=/usr \
+            --disable-static \
+            --disable-xzdec \
+            --disable-lzmadec \
+            CFLAGS='-march=i686 -mtune=generic -O2'
+    make
+    make DESTDIR=$PKG install-strip
+    make clean
+    ./configure \
+            --prefix=/usr \
+            --disable-shared \
+            --disable-nls \
+            --disable-encoders \
+            --enable-small \
+            --disable-threads \
+            CFLAGS='-march=i686 -mtune=generic -Os'
+    make -C src/liblzma
+    make -C src/xzdec
+    make -C src/xzdec DESTDIR=$PKG install-strip
+    cp -a extra $PKG/usr/share/doc/xz

+
+0. Overview
+-----------
+
+    XZ Utils provide a general-purpose data-compression library plus
+    command-line tools. The native file format is the .xz format, but
+    also the legacy .lzma format is supported. The .xz format supports
+    multiple compression algorithms, which are called "filters" in the
+    context of XZ Utils. The primary filter is currently LZMA2. With
+    typical files, XZ Utils create about 30 % smaller files than gzip.
+
+    To ease adapting support for the .xz format into existing applications
+    and scripts, the API of liblzma is somewhat similar to the API of the
+    popular zlib library. For the same reason, the command-line tool xz
+    has a command-line syntax similar to that of gzip.
+
+    When aiming for the highest compression ratio, the LZMA2 encoder uses
+    a lot of CPU time and may use, depending on the settings, even
+    hundreds of megabytes of RAM. However, in fast modes, the LZMA2 encoder
+    competes with bzip2 in compression speed, RAM usage, and compression
+    ratio.
+
+    LZMA2 is reasonably fast to decompress. It is a little slower than
+    gzip, but a lot faster than bzip2. Being fast to decompress means
+    that the .xz format is especially nice when the same file will be
+    decompressed very many times (usually on different computers), which
+    is the case e.g. when distributing software packages. In such
+    situations, it's not too bad if the compression takes some time,
+    since that needs to be done only once to benefit many people.
+
+    With some file types, combining (or "chaining") LZMA2 with an
+    additional filter can improve the compression ratio. A filter chain may
+    contain up to four filters, although usually only one or two are used.
+    For example, putting a BCJ (Branch/Call/Jump) filter before LZMA2
+    in the filter chain can improve compression ratio of executable files.
+
+    Since the .xz format allows adding new filter IDs, it is possible that
+    some day there will be a filter that is, for example, much faster to
+    compress than LZMA2 (but probably with worse compression ratio).
+    Similarly, it is possible that some day there is a filter that will
+    compress better than LZMA2.
+
+    XZ Utils supports multithreaded compression. XZ Utils doesn't support
+    multithreaded decompression yet. It has been planned though and taken
+    into account when designing the .xz file format. In the future, files
+    that were created in threaded mode can be decompressed in threaded
+    mode too.

+    AUTHORS             The main authors of XZ Utils
+    THANKS              Incomplete list of people who have helped making
+                        this software
+    NEWS                User-visible changes between XZ Utils releases
+    ChangeLog           Detailed list of changes (commit log)
+    TODO                Known bugs and some sort of to-do list
+
+    Note that only some of the above files are included in binary
+    packages.
+
+
+1.2. Documentation for command-line tools
+
+    The command-line tools are documented as man pages. In source code
+    releases (and possibly also in some binary packages), the man pages
+    are also provided in plain text (ASCII only) and PDF formats in the
+    directory "doc/man" to make the man pages more accessible to those
+    whose operating system doesn't provide an easy way to view man pages.
+
+
+1.3. Documentation for liblzma
+
+    The liblzma API headers include short docs about each function
+    and data type as Doxygen tags. These docs should be quite OK as
+    a quick reference.
+
+    There are a few example/tutorial programs that should help in
+    getting started with liblzma. In the source package the examples
+    are in "doc/examples" and in binary packages they may be under
+    "examples" in the same directory as this README.
+
+    Since the liblzma API has similarities to the zlib API, some people
+    may find it useful to read the zlib docs and tutorial too:
+
+        https://zlib.net/manual.html
+        https://zlib.net/zlib_how.html
+
+
+2. Version numbering
+--------------------
+
+    The version number format of XZ Utils is X.Y.ZS:
+
+      - X is the major version. When this is incremented, the library
+        API and ABI break.
+
+      - Y is the minor version. It is incremented when new features
+        are added without breaking the existing API or ABI. An even Y
+        indicates a stable release and an odd Y indicates unstable
+        (alpha or beta version).
+
+      - Z is the revision. This has a different meaning for stable and
+        unstable releases:
+
+          * Stable: Z is incremented when bugs get fixed without adding
+            any new features. This is intended to be convenient for
+            downstream distributors that want bug fixes but don't want
+            any new features to minimize the risk of introducing new bugs.
+
+          * Unstable: Z is just a counter. API or ABI of features added
+            in earlier unstable releases having the same X.Y may break.
+
+      - S indicates stability of the release. It is missing from the
+        stable releases, where Y is an even number. When Y is odd, S
+        is either "alpha" or "beta" to make it very clear that such
+        versions are not stable releases. The same X.Y.Z combination is
+        not used for more than one stability level, i.e. after X.Y.Zalpha,
+        the next version can be X.Y.(Z+1)beta but not X.Y.Zbeta.
+
+
+3. Reporting bugs
+-----------------
+
+    Naturally it is easiest for me if you already know what causes the
+    unexpected behavior. Even better if you have a patch to propose.
+    However, quite often the reason for unexpected behavior is unknown,
+    so here are a few things to do before sending a bug report:
+
+      1. Try to create a small example how to reproduce the issue.
+
+      2. Compile XZ Utils with debugging code using configure switches
+         --enable-debug and, if possible, --disable-shared. If you are
+         using GCC, use CFLAGS='-O0 -ggdb3'. Don't strip the resulting
+         binaries.
+
+      3. Turn on core dumps. The exact command depends on your shell;
+         for example in GNU bash it is done with "ulimit -c unlimited",
+         and in tcsh with "limit coredumpsize unlimited".
+
+      4. Try to reproduce the suspected bug. If you get "assertion failed"
+         message, be sure to include the complete message in your bug
+         report. If the application leaves a coredump, get a backtrace
+         using gdb:
+           $ gdb /path/to/app-binary   # Load the app to the debugger.
+           (gdb) core core   # Open the coredump.
+           (gdb) bt   # Print the backtrace. Copy & paste to bug report.
+           (gdb) quit   # Quit gdb.
+
+    Report your bug via email or IRC (see Contact information below).
+    Don't send core dump files or any executables. If you have a small
+    example file(s) (total size less than 256 KiB), please include
+    it/them as an attachment. If you have bigger test files, put them
+    online somewhere and include a URL to the file(s) in the bug report.
+
+    Always include the exact version number of XZ Utils in the bug report.
+    If you are using a snapshot from the git repository, use "git describe"
+    to get the exact snapshot version. If you are using XZ Utils shipped
+    in an operating system distribution, mention the distribution name,
+    distribution version, and exact xz package version; if you cannot
+    repeat the bug with the code compiled from unpatched source code,
+    you probably need to report a bug to your distribution's bug tracking
+    system.
+
+
+4. Translations
+---------------
+
+    The xz command line tool and all man pages can be translated.
+    The translations are handled via the Translation Project. If you
+    wish to help translating xz, please join the Translation Project:
+
+        https://translationproject.org/html/translators.html
+
+    Below are notes and testing instructions specific to xz
+    translations.
+
+    Testing can be done by installing xz into a temporary directory:
+
+        ./configure --disable-shared --prefix=/tmp/xz-test
+        # <Edit the .po file in the po directory.>
+        make -C po update-po
+        make install
+        bash debug/translation.bash | less
+        bash debug/translation.bash | less -S  # For --list outputs
+
+    Repeat the above as needed (no need to re-run configure though).
+
+    Note especially the following:
+
+      - The output of --help and --long-help must look nice on
+        an 80-column terminal. It's OK to add extra lines if needed.
+
+      - In contrast, don't add extra lines to error messages and such.
+        They are often preceded with e.g. a filename on the same line,
+        so you have no way to predict where to put a \n. Let the terminal
+        do the wrapping even if it looks ugly. Adding new lines will be
+        even uglier in the generic case even if it looks nice in a few
+        limited examples.
+
+      - Be careful with column alignment in tables and table-like output
+        (--list, --list --verbose --verbose, --info-memory, --help, and
+        --long-help):
+
+          * All descriptions of options in --help should start in the
+            same column (but it doesn't need to be the same column as
+            in the English messages; just be consistent if you change it).
+            Check that both --help and --long-help look OK, since they
+            share several strings.
+
+          * --list --verbose and --info-memory print lines that have
+            the format "Description:   %s". If you need a longer
+            description, you can put extra space between the colon
+            and %s. Then you may need to add extra space to other
+            strings too so that the result as a whole looks good (all
+            values start at the same column).
+
+          * The columns of the actual tables in --list --verbose --verbose
+            should be aligned properly. Abbreviate if necessary. It might
+            be good to keep at least 2 or 3 spaces between column headings
+            and avoid spaces in the headings so that the columns stand out
+            better, but this is a matter of opinion. Do what you think
+            looks best.
+
+      - Be careful to put a period at the end of a sentence when the
+        original version has it, and don't put it when the original
+        doesn't have it. Similarly, be careful with \n characters
+        at the beginning and end of the strings.
+
+      - Read the TRANSLATORS comments that have been extracted from the
+        source code and included in xz.pot. Some comments suggest
+        testing with a specific command which needs an .xz file. You
+        may use e.g. any tests/files/good-*.xz. However, these test
+        commands are included in translations.bash output, so reading
+        translations.bash output carefully can be enough.
+
+      - If you find language problems in the original English strings,
+        feel free to suggest improvements. Ask if something is unclear.
+
+      - The translated messages should be understandable (sometimes this
+        may be a problem with the original English messages too). Don't
+        make a direct word-by-word translation from English especially if
+        the result doesn't sound good in your language.
+
+    Thanks for your help!
+
+
+5. Other implementations of the .xz format
+------------------------------------------
+
+    7-Zip and the p7zip port of 7-Zip support the .xz format starting
+    from the version 9.00alpha.
+
+        https://7-zip.org/
+        https://p7zip.sourceforge.net/
+
+    XZ Embedded is a limited implementation written for use in the Linux
+    kernel, but it is also suitable for other embedded use.
+
+        https://tukaani.org/xz/embedded.html
+
+    XZ for Java is a complete implementation written in pure Java.
+
+        https://tukaani.org/xz/java.html
+
+
+6. Contact information

+
+    If you have questions, bug reports, patches etc. related to XZ Utils,
+    the project maintainers Lasse Collin and Jia Tan can be reached via
+    <xz@tukaani.org>.
+
+    You might find Lasse also from #tukaani on Libera Chat (IRC).

+
+XZ Utils To-Do List
+===================
+
+Known bugs
+----------
+
+    The test suite is too incomplete.
+
+    If the memory usage limit is less than about 13 MiB, xz is unable to
+    automatically scale down the compression settings enough even though
+    it would be  possible by switching from BT2/BT3/BT4 match finder to
+    HC3/HC4.
+
+    XZ Utils compress some files significantly worse than LZMA Utils.
+    This is due to faster compression presets used by XZ Utils, and
+    can often be worked around by using "xz --extreme". With some files
+    --extreme isn't enough though: it's most likely with files that
+    compress extremely well, so going from compression ratio of 0.003
+    to 0.004 means big relative increase in the compressed file size.
+
+    xz doesn't quote unprintable characters when it displays file names
+    given on the command line.
+
+    tuklib_exit() doesn't block signals => EINTR is possible.
+
+    SIGTSTP is not handled. If xz is stopped, the estimated remaining
+    time and calculated (de)compression speed won't make sense in the
+    progress indicator (xz --verbose).
+
+    If liblzma has created threads and fork() gets called, liblzma
+    code will break in the child process unless it calls exec() and
+    doesn't touch liblzma.
+
+
+Missing features
+----------------
+
+    Add support for storing metadata in .xz files. A preliminary
+    idea is to create a new Stream type for metadata. When both
+    metadata and data are wanted in the same .xz file, two or more
+    Streams would be concatenated.
+
+    The state stored in lzma_stream should be cloneable, which would
+    be mostly useful when using a preset dictionary in LZMA2, but
+    it may have other uses too. Compare to deflateCopy() in zlib.
+
+    Support LZMA_FINISH in raw decoder to indicate end of LZMA1 and
+    other streams that don't have an end of payload marker.
+
+    Adjust dictionary size when the input file size is known.
+    Maybe do this only if an option is given.
+
+    xz doesn't support copying extended attributes, access control
+    lists etc. from source to target file.
+
+    Multithreaded compression:
+      - Reduce memory usage of the current method.
+      - Implement threaded match finders.
+      - Implement pigz-style threading in LZMA2.
+
+    Buffer-to-buffer coding could use less RAM (especially when
+    decompressing LZMA1 or LZMA2).
+
+    I/O library is not implemented (similar to gzopen() in zlib).
+    It will be a separate library that supports uncompressed, .gz,
+    .bz2, .lzma, and .xz files.
+
+    Support changing lzma_options_lzma.mode with lzma_filters_update().
+
+    Support LZMA_FULL_FLUSH for lzma_stream_decoder() to stop at
+    Block and Stream boundaries.
+
+    lzma_strerror() to convert lzma_ret to human readable form?
+    This is tricky, because the same error codes are used with
+    slightly different meanings, and this cannot be fixed anymore.
+
+    Make it possible to adjust LZMA2 options in the middle of a Block
+    so that the encoding speed vs. compression ratio can be optimized
+    when the compressed data is streamed over network.
+
+    Improved BCJ filters. The current filters are small but they aren't
+    so great when compressing binary packages that contain various file
+    types. Specifically, they make things worse if there are static
+    libraries or Linux kernel modules. The filtering could also be
+    more effective (without getting overly complex), for example,
+    streamable variant BCJ2 from 7-Zip could be implemented.
+
+    Filter that autodetects specific data types in the input stream
+    and applies appropriate filters for the corrects parts of the input.
+    Perhaps combine this with the BCJ filter improvement point above.
+
+    Long-range LZ77 method as a separate filter or as a new LZMA2
+    match finder.
+
+
+Documentation
+-------------
+
+    More tutorial programs are needed for liblzma.
+
+    Document the LZMA1 and LZMA2 algorithms.
+
+
+Miscellaneous
+------------
+
+    Try to get the media type for .xz registered at IANA.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+# Configuration subroutine to validate and canonicalize a configuration type.
+# Supply the specified configuration type as an argument.
+# If it is invalid, we print an error message on stderr and exit with code 1.
+# Otherwise, we print the canonical config type on stdout and succeed.
+
+# You can get the latest version of this script from:
+# https://git.savannah.gnu.org/cgit/config.git/plain/config.sub
+
+# This file is supposed to be the same for all GNU packages
+# and recognize all the CPU types, system types and aliases
+# that are meaningful with *any* GNU software.
+# Each package is responsible for reporting which valid configurations
+# it does not support.  The user should be able to distinguish
+# a failure to support a valid configuration from a meaningless
+# configuration.
+
+# The goal of this file is to map all the various variations of a given
+# machine specification into a single specification in the form:
+#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# or in some cases, the newer four-part form:
+#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
+# It is wrong to echo any other type of specification.
+
+# The "shellcheck disable" line above the timestamp inhibits complaints
+# about features and limitations of the classic Bourne shell that were
+# superseded or lifted in POSIX.  However, this script identifies a wide
+# variety of pre-POSIX systems that do not have POSIX shells at all, and
+# even some reasonably current systems (Solaris 10 as case-in-point) still
+# have a pre-POSIX /bin/sh.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## This next piece of magic avoids the "deleted header file" problem.
+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH
+## to the object.  Take care to not repeat it in the output.

+# 'expand'
+#       - the same as 'eval';  but do not quote variable references

+#       - request aesthetic output, i.e. '"a b"' instead of 'a\ b'.  This might
+#         be used later in func_quote to get output like: 'echo "a b"' instead
+#         of 'echo a\ b'.  This is slower than default on some shells.
+# 'unquoted'
+#       - produce also $func_quote_arg_unquoted_result which does not contain
+#         wrapping double-quotes.

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# Copyright'.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug in processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##

+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to

+# expanded when the contents are evaled.

+  --enable-external-sha256
+                          Use SHA-256 code from the operating system. See
+                          INSTALL for possible subtle problems.
+  --disable-microlzma     Do not build MicroLZMA encoder and decoder. It is
+                          needed by specific applications only, for example,
+                          erofs-utils.
+  --disable-lzip-decoder  Disable decompression support for .lz (lzip) files.
+  --disable-assembler     Do not use assembler optimizations even if such
+                          exist for the architecture.
+  --disable-clmul-crc     Do not use carryless multiplication for CRC
+                          calculation even if support for it is detected.
+  --enable-small          Make liblzma smaller and a little slower. This is

+  --enable-threads=METHOD Supported METHODS are `yes', `no', `posix', `win95',
+                          and `vista'. The default is `yes'. Using `no'
+                          together with --enable-small makes liblzma thread
+                          unsafe.
+  --enable-assume-ram=SIZE
+                          If and only if the real amount of RAM cannot be
+                          determined, assume SIZE MiB. The default is 128 MiB.
+                          This affects the default memory usage limit.
+  --disable-xz            do not build the xz tool
+  --disable-xzdec         do not build xzdec
+  --disable-lzmadec       do not build lzmadec (it exists primarily for LZMA

+  --disable-scripts       do not install the scripts xzdiff, xzgrep, xzless,
+                          xzmore, and their symlinks
+  --disable-doc           do not install documentation files to docdir (man
+                          pages will still be installed)
+  --enable-sandbox=METHOD Sandboxing METHOD can be `auto', `no', `capsicum',
+                          or `pledge'. The default is `auto' which enables
+                          sandboxing if a supported sandboxing method is
+                          found.
+  --enable-path-for-scripts=PREFIX
+                          If PREFIX isn't empty, PATH=PREFIX:$PATH will be set
+                          in the beginning of the scripts (xzgrep and others).
+                          The default is empty except on Solaris the default
+                          is /usr/xpg4/bin.
+  --enable-silent-rules   less verbose build output (undo: "make V=1")
+  --disable-silent-rules  verbose build output (undo: "make V=0")
+  --enable-dependency-tracking
+                          do not reject slow dependency extractors
+  --disable-dependency-tracking
+                          speeds up one-time build
+  --enable-shared[=PKGS]  build shared libraries [default=yes]
+  --enable-static[=PKGS]  build static libraries [default=yes]
+  --enable-fast-install[=PKGS]
+                          optimize for fast installation [default=yes]
+  --disable-libtool-lock  avoid locking (might break parallel builds)
+  --enable-symbol-versions
+                          Use symbol versioning for liblzma. Enabled by
+                          default on GNU/Linux, other GNU-based systems, and
+                          FreeBSD.
+  --disable-nls           do not use Native Language Support
+  --disable-rpath         do not hardcode runtime library paths
+  --disable-largefile     omit support for large files
+  --enable-unaligned-access
+                          Enable if the system supports *fast* unaligned
+                          memory access with 16-bit, 32-bit, and 64-bit
+                          integers. By default, this is enabled only on x86,
+                          x86_64, big endian PowerPC, and some ARM systems.
+  --enable-unsafe-type-punning
+                          This introduces strict aliasing violations and may
+                          result in broken code. However, this might improve
+                          performance in some cases, especially with old
+                          compilers (e.g. GCC 3 and early 4.x on x86, GCC < 6
+                          on ARMv6 and ARMv7).
+  --enable-werror         Enable -Werror to abort compilation on all compiler
+                          warnings.
+
+Optional Packages:
+  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
+  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
+  --with-pic[=PKGS]       try to use only PIC/non-PIC objects [default=use
+                          both]
+  --with-aix-soname=aix|svr4|both
+                          shared library versioning (aka "SONAME") variant to
+                          provide on AIX, [default=aix].
+  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
+  --with-sysroot[=DIR]    Search for dependent libraries within DIR (or the
+                          compiler's sysroot if not specified).
+  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
+  --with-libiconv-prefix[=DIR]  search for libiconv in DIR/include and DIR/lib
+  --without-libiconv-prefix     don't search for libiconv in includedir and libdir
+  --with-libintl-prefix[=DIR]  search for libintl in DIR/include and DIR/lib
+  --without-libintl-prefix     don't search for libintl in includedir and libdir
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CCAS        assembler compiler command (defaults to CC)
+  CCASFLAGS   assembler compiler flags (defaults to CFLAGS)
+  CPP         C preprocessor
+  LT_SYS_LIBRARY_PATH
+              User-defined run-time library search path.
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+Debug tools
+-----------
+
+    This directory contains a few tiny programs that may be helpful when
+    debugging XZ Utils.
+
+    These tools are not meant to be installed. Often one needs to edit
+    the source code a little to make the programs do the wanted things.
+    If you don't know how these programs could help you, it is likely
+    that they really are useless to you.
+
+    These aren't intended to be used as example programs. They take some
+    shortcuts here and there, which correct programs should not do. Many
+    possible errors (especially I/O errors) are ignored. Don't report
+    bugs or send patches to fix this kind of bugs.

+<p>Initialization for <a class="el" href="structlzma__stream.html" title="Passing data to and from liblzma.">lzma_stream</a>. </p>
+<p>When you declare an instance of <a class="el" href="structlzma__stream.html" title="Passing data to and from liblzma.">lzma_stream</a>, you can immediately initialize it so that initialization functions know that no memory has been allocated yet:</p>
+<p><a class="el" href="structlzma__stream.html" title="Passing data to and from liblzma.">lzma_stream</a> strm = LZMA_STREAM_INIT;</p>
+<p>If you need to initialize a dynamically allocated <a class="el" href="structlzma__stream.html" title="Passing data to and from liblzma.">lzma_stream</a>, you can use memset(strm_pointer, 0, sizeof(lzma_stream)). Strictly speaking, this violates the C standard since NULL may have different internal representation than zero, but it should be portable enough in practice. Anyway, for maximum portability, you can use something like this:</p>
+<p><a class="el" href="structlzma__stream.html" title="Passing data to and from liblzma.">lzma_stream</a> tmp = LZMA_STREAM_INIT; *strm = tmp; </p>

+<p>This flag makes the threaded decoder report errors (like LZMA_DATA_ERROR) as soon as they are detected. This saves time when the application has no interest in a partially decompressed truncated or corrupt file. Note that due to timing randomness, if the same truncated or corrupt input is decompressed multiple times with this flag, a different amount of output may be produced by different runs, and even the error code might vary.</p>
+<p>When using LZMA_FAIL_FAST, it is recommended to use LZMA_FINISH to tell the decoder when no more input will be coming because it can help fast detection and reporting of truncated files. Note that in this situation truncated files might be diagnosed with LZMA_DATA_ERROR instead of LZMA_OK or LZMA_BUF_ERROR!</p>
+<p>Without this flag the threaded decoder will provide as much output as possible at first and then report the pending error. This default behavior matches the single-threaded decoder and provides repeatable behavior with truncated or corrupt input. There are a few special cases where the behavior can still differ like memory allocation failures (LZMA_MEM_ERROR).</p>
+<p>Single-threaded decoders currently ignore this flag.</p>
+<p>Support for this flag was added in liblzma 5.3.3alpha. Note that in older versions this flag isn't supported (LZMA_OPTIONS_ERROR) even by functions that ignore this flag in newer liblzma versions. </p>

+<p>MicroLZMA encoder. </p>
+<p>The MicroLZMA format is a raw LZMA stream whose first byte (always 0x00) has been replaced with bitwise-negation of the LZMA properties (lc/lp/pb). This encoding ensures that the first byte of MicroLZMA stream is never 0x00. There is no end of payload marker and thus the uncompressed size must be stored separately. For the best error detection the dictionary size should be stored separately as well but alternatively one may use the uncompressed size as the dictionary size when decoding.</p>
+<p>With the MicroLZMA encoder, <a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a> behaves slightly unusually. The action argument must be LZMA_FINISH and the return value will never be LZMA_OK. Thus the encoding is always done with a single <a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a> after the initialization.

+<p><a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a> will try to encode as much input as is possible to fit into the given output buffer. If not all input can be encoded, the stream will be finished without encoding all the input. The caller must check both input and output buffer usage after <a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a> (total_in and total_out in <a class="el" href="structlzma__stream.html" title="Passing data to and from liblzma.">lzma_stream</a> can be convenient). Often <a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a> can fill the output buffer completely if there is a lot of input, but sometimes a few bytes may remain unused because the next LZMA symbol would require more space.</p>
+<p><a class="el" href="structlzma__stream.html#a5ff28ea4e39148723c19f59811627904">lzma_stream.avail_out</a> must be at least 6. Otherwise LZMA_PROG_ERROR will be returned.</p>
+<p>The LZMA dictionary should be reasonably low to speed up the encoder re-initialization. A good value is bigger than the resulting uncompressed size of most of the output chunks. For example, if output size is 4 KiB, dictionary size of 32 KiB or 64 KiB is good. If the data compresses extremely well, even 128 KiB may be useful.</p>
+<p>The MicroLZMA format and this encoder variant were made with the EROFS file system in mind. This format may be convenient in other embedded uses too where many small streams are needed. XZ Embedded includes a decoder for this format.</p>

+<p>Initialize .lz (lzip) decoder (a foreign file format) </p>
+<p>This decoder supports the .lz format version 0 and the unextended .lz format version 1:</p>
+<ul>
+<li>Files in the format version 0 were produced by lzip 1.3 and older. Such files aren't common but may be found from file archives as a few source packages were released in this format. People might have old personal files in this format too. Decompression support for the format version 0 was removed in lzip 1.18.</li>
+<li>lzip 1.3 added decompression support for .lz format version 1 files. Compression support was added in lzip 1.4. In lzip 1.6 the .lz format version 1 was extended to support the Sync Flush marker. This extension is not supported by liblzma. <a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a> will return LZMA_DATA_ERROR at the location of the Sync Flush marker. In practice files with the Sync Flush marker are very rare and thus liblzma can decompress almost all .lz files.</li>
+</ul>
+<p>Just like with <a class="el" href="container_8h.html#a02b7683ef98d8049788961370a8b28c0" title="Initialize .xz Stream decoder.">lzma_stream_decoder()</a> for .xz files, LZMA_CONCATENATED should be used when decompressing normal standalone .lz files.</p>
+<p>The .lz format allows putting non-.lz data at the end of a file after at least one valid .lz member. That is, one can append custom data at the end of a .lz file and the decoder is required to ignore it. In liblzma this is relevant only when LZMA_CONCATENATED is used. In that case <a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a> will return LZMA_STREAM_END and leave <a class="el" href="structlzma__stream.html#a72fdc738c793f07a5c29715aa57802cf">lzma_stream.next_in</a> pointing to the first byte of the non-.lz data. An exception to this is if the first 1-3 bytes of the non-.lz data are identical to the .lz magic bytes (0x4C, 0x5A, 0x49, 0x50; "LZIP" in US-ASCII). In such a case the 1-3 bytes will have been ignored by <a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a>. If one wishes to locate the non-.lz data reliably, one must ensure that the first byte isn't 0x4C. Actually one should ensure that none of the first four bytes of trailing data are equal to the magic bytes because lzip &gt;= 1.20 requires it by default.</p>

+<p>Convert a string to a filter chain. </p>
+<p>This tries to make it easier to write applications that allow users to set custom compression options. This only handles the filter configuration (including presets) but not the number of threads, block size, check type, or memory limits.</p>
+<p>The input string can be either a preset or a filter chain. Presets begin with a digit 0-9 and may be followed by zero or more flags which are lower-case letters. Currently only "e" is supported, matching LZMA_PRESET_EXTREME. For partial xz command line syntax compatibility, a preset string may start with a single dash "-".</p>
+<p>A filter chain consists of one or more "filtername:opt1=value1,opt2=value2" strings separated by one or more spaces. Leading and trailing spaces are ignored. All names and values must be lower-case. Extra commas in the option list are ignored. The order of filters is significant: when encoding, the uncompressed input data goes to the leftmost filter first. Normally "lzma2" is the last filter in the chain.</p>
+<p>If one wishes to avoid spaces, for example, to avoid shell quoting, it is possible to use two dashes "--" instead of spaces to separate the filters.</p>
+<p>For xz command line compatibility, each filter may be prefixed with two dashes "--" and the colon ":" separating the filter name from the options may be replaced with an equals sign "=".</p>
+<p>By default, only filters that can be used in the .xz format are accepted. To allow all filters (LZMA1) use the flag LZMA_STR_ALL_FILTERS.</p>
+<p>By default, very basic validation is done for the filter chain as a whole, for example, that LZMA2 is only used as the last filter in the chain. The validation isn't perfect though and it's possible that this function succeeds but using the filter chain for encoding or decoding will still result in LZMA_OPTIONS_ERROR. To disable this validation, use the flag LZMA_STR_NO_VALIDATION.</p>
+<p>The available filter names and their options are available via <a class="el" href="filter_8h.html#ab51585b68796ce0270f87e615b923809" title="List available filters and/or their options (for help message)">lzma_str_list_filters()</a>. See the xz man page for the description of filter names and options.</p>
+<p>For command line applications, below is an example how an error message can be displayed. Note the use of an empty string for the field width. If "^" was used there it would create an off-by-one error except at the very beginning of the line.</p>

+<p>Since liblzma can consume a lot of system resources, it also provides ways to limit the resource usage. Applications linking against liblzma need to do the actual decisions how much resources to let liblzma to use. To ease making these decisions, liblzma provides functions to find out the relevant capabilities of the underlying hardware. Currently there is only a function to find out the amount of RAM, but in the future there will be also a function to detect how many concurrent threads the system can run.</p>
+<dl class="section note"><dt>Note</dt><dd>On some operating systems, these function may temporarily load a shared library or open file descriptor(s) to find out the requested hardware information. Unless the application assumes that specific file descriptors are not touched by other threads, this should have no effect on thread safety. Possible operations involving file descriptors will restart the syscalls if they return EINTR. </dd></dl>

+<div class="textblock"><p>liblzma is a public domain general-purpose data compression library with a zlib-like API. The native file format is .xz, but also the old .lzma format and raw (no headers) streams are supported. Multiple compression algorithms (filters) are supported. Currently LZMA2 is the primary filter.</p>
+<p>liblzma is part of XZ Utils <a href="https://tukaani.org/xz/">https://tukaani.org/xz/</a>. XZ Utils includes a gzip-like command line tool named xz and some other tools. XZ Utils is developed and maintained by Lasse Collin and Jia Tan.</p>
+<p>Major parts of liblzma are based on Igor Pavlov's public domain LZMA SDK <a href="https://7-zip.org/sdk.html">https://7-zip.org/sdk.html</a>.</p>
+<p>The SHA-256 implementation is based on the public domain code found from 7-Zip <a href="https://7-zip.org/">https://7-zip.org/</a>, which has a modified version of the public domain SHA-256 code found from Crypto++ <a href="https://www.cryptopp.com/">https://www.cryptopp.com/</a>. The SHA-256 code in Crypto++ was written by Kevin Springle and Wei Dai. </p>

+<p>lzma_index often holds just one .xz Index and possibly the Stream Flags of the same Stream and size of the Stream Padding field.

+<p>On disk, the size of the Index field depends on both the number of Records stored and the size of the Records (due to variable-length integer encoding). When the Index is kept in lzma_index structure, the memory usage depends only on the number of Records/Blocks stored in the Index(es), and in case of concatenated lzma_indexes, the number of Streams.

+<p>Initialize a .xz file information decoder. </p>
+<p>This decoder decodes the Stream Header, Stream Footer, Index, and Stream Padding field(s) from the input .xz file and stores the resulting combined index in *dest_index. This information can be used to get the uncompressed file size with lzma_index_uncompressed_size(*dest_index) or, for example, to implement random access reading by locating the Blocks in the Streams.</p>
+<p>To get the required information from the .xz file, <a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a> may ask the application to seek in the input file by returning LZMA_SEEK_NEEDED and having the target file position specified in <a class="el" href="structlzma__stream.html#af7c43a61f3dfeb0b9c8487b7f275054e" title="New seek input position for LZMA_SEEK_NEEDED.">lzma_stream.seek_pos</a>. The number of seeks required depends on the input file and how big buffers the application provides. When possible, the decoder will seek backward and forward in the given buffer to avoid useless seek requests. Thus, if the application provides the whole file at once, no external seeking will be required (that is, <a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a> won't return LZMA_SEEK_NEEDED).</p>

However, due to seeking and the way total_in is updated, the value of total_in will be somewhat inaccurate (a little too big). Thus, total_in is a good estimate but don't expect to see the same exact value for the same file if you change the input buffer size or switch to a different liblzma version.</p>

+<p>LZMA1 Filter ID with extended options (for raw encoder/decoder) </p>
+<p>This is like LZMA_FILTER_LZMA1 but with this ID a few extra options are supported in the <a class="el" href="structlzma__options__lzma.html" title="Options specific to the LZMA1 and LZMA2 filters.">lzma_options_lzma</a> structure:</p>
+<ul>
+<li>A flag to tell the encoder if the end of payload marker (EOPM) alias end of stream (EOS) marker must be written at the end of the stream. In contrast, LZMA_FILTER_LZMA1 always writes the end marker.</li>
+<li>Decoder needs to be told the uncompressed size of the stream or that it is unknown (using the special value UINT64_MAX). If the size is known, a flag can be set to allow the presence of the end marker anyway. In contrast, LZMA_FILTER_LZMA1 always behaves as if the uncompressed size was unknown.</li>
+</ul>
+<p>This allows handling file formats where LZMA1 streams are used but where the end marker isn't allowed or where it might not (always) be present. This extended LZMA1 functionality is provided as a Filter ID for raw encoder and decoder instead of adding new encoder and decoder initialization functions because this way it is possible to also use extra filters, for example, LZMA_FILTER_X86 in a filter chain with LZMA_FILTER_LZMA1EXT, which might be needed to handle some file formats. </p>

+<div class="textblock"><p>Filter options. </p>
+<p>This structure is used to pass a Filter ID and a pointer to the filter's options to liblzma. A few functions work with a single <a class="el" href="structlzma__filter.html" title="Filter options.">lzma_filter</a> structure, while most functions expect a filter chain.</p>
+<p>A filter chain is indicated with an array of <a class="el" href="structlzma__filter.html" title="Filter options.">lzma_filter</a> structures. The array is terminated with .id = LZMA_VLI_UNKNOWN. Thus, the filter array must have LZMA_FILTERS_MAX + 1 elements (that is, five) to be able to hold any arbitrary filter chain. This is important when using <a class="el" href="block_8h.html#a7f5487c21a7b36a8bd17be36074d43c9" title="Decode Block Header.">lzma_block_header_decode()</a> from <a class="el" href="block_8h.html" title=".xz Block handling">block.h</a>, because a filter array that is too small would make liblzma write past the end of the array. </p>

+<p>With LZMA2, a recommended block size is 2-4 times the LZMA2 dictionary size. With very small dictionaries, it is recommended to use at least 1 MiB block size for good compression ratio, even if this is more than four times the dictionary size.

+<p>Decoder:</p>
+<p>If the number of threads has been set so high that more than memlimit_threading bytes of memory would be needed, the number of threads will be reduced so that the memory usage will not exceed memlimit_threading bytes. However, if memlimit_threading cannot be met even in single-threaded mode, then decoding will continue in single-threaded mode and memlimit_threading may be exceeded even by a large amount. That is, memlimit_threading will never make <a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a> return LZMA_MEMLIMIT_ERROR. To truly cap the memory usage, see memlimit_stop below.</p>
+<p>Setting memlimit_threading to UINT64_MAX or a similar huge value means that liblzma is allowed to keep the whole compressed file and the whole uncompressed file in memory in addition to the memory needed by the decompressor data structures used by each thread! In other words, a reasonable value limit must be set here or it will cause problems sooner or later. If you have no idea what a reasonable value could be, try <a class="el" href="hardware_8h.html#a85363e453b34272a9f26c9fdffb041ee" title="Get the total amount of physical memory (RAM) in bytes.">lzma_physmem()</a> / 4 as a starting point. Setting this limit will never prevent decompression of a file; this will only reduce the number of threads.</p>
+<p>If memlimit_threading is greater than memlimit_stop, then the value of memlimit_stop will be used for both. </p>

+<p>Dictionary size in bytes. </p>
+<p>Dictionary size indicates how many bytes of the recently processed uncompressed data is kept in memory. One method to reduce size of the uncompressed data is to store distance-length pairs, which indicate what data to repeat from the dictionary buffer. Thus, the bigger the dictionary, the better the compression ratio usually is.</p>
+<p>Maximum size of the dictionary depends on multiple things:</p><ul>
+<li>Memory usage limit</li>
+<li>Available address space (not a problem on 64-bit systems)</li>
+<li>Selected match finder (encoder only)</li>
+</ul>
+<p>Currently the maximum dictionary size for encoding is 1.5 GiB (i.e. (UINT32_C(1) &lt;&lt; 30) + (UINT32_C(1) &lt;&lt; 29)) even on 64-bit systems for certain match finder implementation reasons. In the future, there may be match finders that support bigger dictionaries.</p>
+<p>Decoder already supports dictionaries up to 4 GiB - 1 B (i.e. UINT32_MAX), so increasing the maximum dictionary size of the encoder won't cause problems for old decoders.</p>
+<p>Because extremely small dictionaries sizes would have unneeded overhead in the decoder, the minimum dictionary size is 4096 bytes.</p>

+<p>Pointer to an initial dictionary. </p>
+<p>It is possible to initialize the LZ77 history window using a preset dictionary. It is useful when compressing many similar, relatively small chunks of data independently from each other. The preset dictionary should contain typical strings that occur in the files being compressed. The most probable strings should be near the end of the preset dictionary.</p>
+<p>This feature should be used only in special situations. For now, it works correctly only with raw encoding and decoding. Currently none of the container formats supported by liblzma allow preset dictionary when decoding, thus if you create a .xz or .lzma file with preset dictionary, it cannot be decoded with the regular decoder functions. In the future, the .xz format will likely get support for preset dictionary though. </p>

+<p>Number of literal context bits. </p>
+<p>How many of the highest bits of the previous uncompressed eight-bit byte (also known as `literal') are taken into account when predicting the bits of the next literal.</p>
+<p>E.g. in typical English text, an upper-case letter is often followed by a lower-case letter, and a lower-case letter is usually followed by another lower-case letter. In the US-ASCII character set, the highest three bits are 010 for upper-case letters and 011 for lower-case letters. When lc is at least 3, the literal coding can take advantage of this property in the uncompressed data.</p>
+<p>There is a limit that applies to literal context bits and literal position bits together: lc + lp &lt;= 4. Without this limit the decoding could become very slow, which could have security related results in some cases like email servers doing virus scanning. This limit also simplifies the internal implementation in liblzma.</p>

+<p>pb affects what kind of alignment in the uncompressed data is assumed in general. The default means four-byte alignment (2^ pb =2^2=4), which is often a good choice when there's no better guess.</p>
+<p>When the alignment is known, setting pb accordingly may reduce the file size a little. E.g. with text files having one-byte alignment (US-ASCII, ISO-8859-*, UTF-8), setting pb=0 can improve compression slightly. For UTF-16 text, pb=1 is a good choice. If the alignment is an odd number like 3 bytes, pb=0 might be the best choice.</p>
+<p>Even though the assumed alignment can be adjusted with pb and lp, LZMA1 and LZMA2 still slightly favor 16-byte alignment. It might be worth taking into account when designing file formats that are likely to be often compressed with LZMA1 or LZMA2. </p>

+<p>Setting depth to zero tells liblzma to use an automatic default value, that depends on the selected match finder and nice_len. The default is in the range [4, 200] or so (it may vary between liblzma versions).</p>
+<p>Using a bigger depth value than the default can increase compression ratio in some cases. There is no strict maximum value, but high values (thousands or millions) should be used with care: the encoder could remain fast enough with typical input, but malicious input could cause the match finder to slow down dramatically, possibly creating a denial of service attack. </p>

+<ul>
+<li>Encoder: If the flag is set, then end marker is written just like it is with LZMA_FILTER_LZMA1. Without this flag the end marker isn't written and the application has to store the uncompressed size somewhere outside the compressed stream. To decompress streams without the end marker, the application has to set the correct uncompressed size in ext_size_low and ext_size_high.</li>
+<li><p class="startli">Decoder: If the uncompressed size in ext_size_low and ext_size_high is set to the special value UINT64_MAX (indicating unknown uncompressed size) then this flag is ignored and the end marker must always be present, that is, the behavior is identical to LZMA_FILTER_LZMA1.</p>
+<p class="startli">Otherwise, if this flag isn't set, then the input stream must not have the end marker; if the end marker is detected then it will result in LZMA_DATA_ERROR. This is useful when it is known that the stream must not have the end marker and strict validation is wanted.</p>
+<p class="startli">If this flag is set, then it is autodetected if the end marker is present after the specified number of uncompressed bytes has been decompressed (ext_size_low and ext_size_high). The end marker isn't allowed in any other position. This behavior is useful when uncompressed size is known but the end marker may or may not be present. This is the case, for example, in .7z files (valid .7z files that have the end marker in LZMA1 streams are rare but they do exist). </p>

+<p>The 64-bit uncompressed size is needed for decompression with LZMA_FILTER_LZMA1EXT. The size is ignored by the encoder.</p>
+<p>The special value UINT64_MAX indicates that the uncompressed size is unknown and that the end of payload marker (also known as end of stream marker) must be present to indicate the end of the LZMA1 stream. Any other value indicates the expected uncompressed size of the LZMA1 stream. (If LZMA1 was used together with filters that change the size of the data then the uncompressed size of the LZMA1 stream could be different than the final uncompressed size of the filtered stream.)</p>
+<p>ext_size_low holds the least significant 32 bits of the uncompressed size. The most significant 32 bits must be set in ext_size_high. The macro lzma_ext_size_set(opt_lzma, u64size) can be used to set these members.</p>
+<p>The 64-bit uncompressed size is split into two uint32_t variables because there were no reserved uint64_t members and using the same options structure for LZMA_FILTER_LZMA1, LZMA_FILTER_LZMA1EXT, and LZMA_FILTER_LZMA2 was otherwise more convenient than having a new options structure for LZMA_FILTER_LZMA1EXT. (Replacing two uint32_t members with one uint64_t changes the ABI on some systems as the alignment of this struct can increase from 4 bytes to 8.) </p>

+<p>The <a class="el" href="structlzma__stream.html" title="Passing data to and from liblzma.">lzma_stream</a> structure is used for</p><ul>
+<li>passing pointers to input and output buffers to liblzma;</li>
+<li>defining custom memory handler functions; and</li>
+<li>holding a pointer to coder-specific internal data structures.</li>
+</ul>
+<p>Typical usage:</p>
+<ul>
+<li>After allocating <a class="el" href="structlzma__stream.html" title="Passing data to and from liblzma.">lzma_stream</a> (on stack or with malloc()), it must be initialized to LZMA_STREAM_INIT (see LZMA_STREAM_INIT for details).</li>
+<li>Initialize a coder to the <a class="el" href="structlzma__stream.html" title="Passing data to and from liblzma.">lzma_stream</a>, for example by using <a class="el" href="container_8h.html#acbdad999c544872f0f5d242f0d1a4ed4" title="Initialize .xz Stream encoder using a preset number.">lzma_easy_encoder()</a> or <a class="el" href="container_8h.html#a21cbebf2771617bb1e956385cfb353e3" title="Decode .xz, .lzma, and .lz (lzip) files with autodetection.">lzma_auto_decoder()</a>. Some notes:<ul>
+<li>In contrast to zlib, strm-&gt;next_in and strm-&gt;next_out are ignored by all initialization functions, thus it is safe to not initialize them yet.</li>
+<li>The initialization functions always set strm-&gt;total_in and strm-&gt;total_out to zero.</li>
+<li>If the initialization function fails, no memory is left allocated that would require freeing with <a class="el" href="base_8h.html#a854ff37464ae1225febf14db1af43308" title="Free memory allocated for the coder data structures.">lzma_end()</a> even if some memory was associated with the <a class="el" href="structlzma__stream.html" title="Passing data to and from liblzma.">lzma_stream</a> structure when the initialization function was called.</li>
+</ul>
+</li>
+<li>Use <a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a> to do the actual work.</li>
+<li>Once the coding has been finished, the existing <a class="el" href="structlzma__stream.html" title="Passing data to and from liblzma.">lzma_stream</a> can be reused. It is OK to reuse <a class="el" href="structlzma__stream.html" title="Passing data to and from liblzma.">lzma_stream</a> with different initialization function without calling <a class="el" href="base_8h.html#a854ff37464ae1225febf14db1af43308" title="Free memory allocated for the coder data structures.">lzma_end()</a> first. Old allocations are automatically freed.</li>
+<li>Finally, use <a class="el" href="base_8h.html#a854ff37464ae1225febf14db1af43308" title="Free memory allocated for the coder data structures.">lzma_end()</a> to free the allocated memory. <a class="el" href="base_8h.html#a854ff37464ae1225febf14db1af43308" title="Free memory allocated for the coder data structures.">lzma_end()</a> never frees the <a class="el" href="structlzma__stream.html" title="Passing data to and from liblzma.">lzma_stream</a> structure itself.</li>
+</ul>
+<p>Application may modify the values of total_in and total_out as it wants. They are updated by liblzma to match the amount of data read and written but aren't used for anything else except as a possible return values from <a class="el" href="base_8h.html#ab6447cd68eeecbd6b88f21daeb8ce751" title="Get progress information.">lzma_get_progress()</a>. </p>

+<p>In the .xz format, most integers are encoded in a variable-length representation, which is sometimes called little endian base-128 encoding. This saves space when smaller values are more likely than bigger values.</p>
+<p>The encoding scheme encodes seven bits to every byte, using minimum number of bytes required to represent the given value. Encodings that use non-minimum number of bytes are invalid, thus every integer has exactly one encoded representation. The maximum number of bits in a VLI is 63, thus the vli argument must be less than or equal to UINT64_MAX / 2. You should use LZMA_VLI_MAX for clarity. </p>

+liblzma example programs
+========================
+
+Introduction
+
+    The examples are written so that the same comments aren't
+    repeated (much) in later files.
+
+    On POSIX systems, the examples should build by just typing "make".
+
+    The examples that use stdin or stdout don't set stdin and stdout
+    to binary mode. On systems where it matters (e.g. Windows) it is
+    possible that the examples won't work without modification.
+
+
+List of examples
+
+    01_compress_easy.c                  Multi-call compression using
+                                        a compression preset
+
+    02_decompress.c                     Multi-call decompression
+
+    03_compress_custom.c                Like 01_compress_easy.c but using
+                                        a custom filter chain
+                                        (x86 BCJ + LZMA2)
+
+    04_compress_easy_mt.c               Multi-threaded multi-call
+                                        compression using a compression
+                                        preset

+XZ Utils FAQ
+============
+
+Q:  What do the letters XZ mean?
+
+A:  Nothing. They are just two letters, which come from the file format
+    suffix .xz. The .xz suffix was selected, because it seemed to be
+    pretty much unused. It has no deeper meaning.
+
+
+Q:  What are LZMA and LZMA2?
+
+A:  LZMA stands for Lempel-Ziv-Markov chain-Algorithm. It is the name
+    of the compression algorithm designed by Igor Pavlov for 7-Zip.
+    LZMA is based on LZ77 and range encoding.
+
+    LZMA2 is an updated version of the original LZMA to fix a couple of
+    practical issues. In context of XZ Utils, LZMA is called LZMA1 to
+    emphasize that LZMA is not the same thing as LZMA2. LZMA2 is the
+    primary compression algorithm in the .xz file format.
+
+
+Q:  There are many LZMA related projects. How does XZ Utils relate to them?
+
+A:  7-Zip and LZMA SDK are the original projects. LZMA SDK is roughly
+    a subset of the 7-Zip source tree.
+
+    p7zip is 7-Zip's command-line tools ported to POSIX-like systems.
+
+    LZMA Utils provide a gzip-like lzma tool for POSIX-like systems.
+    LZMA Utils are based on LZMA SDK. XZ Utils are the successor to
+    LZMA Utils.
+
+    There are several other projects using LZMA. Most are more or less
+    based on LZMA SDK. See <https://7-zip.org/links.html>.
+
+
+Q:  Why is liblzma named liblzma if its primary file format is .xz?
+    Shouldn't it be e.g. libxz?
+
+A:  When the designing of the .xz format began, the idea was to replace
+    the .lzma format and use the same .lzma suffix. It would have been
+    quite OK to reuse the suffix when there were very few .lzma files
+    around. However, the old .lzma format became popular before the
+    new format was finished. The new format was renamed to .xz but the
+    name of liblzma wasn't changed.
+
+
+Q:  Do XZ Utils support the .7z format?
+
+A:  No. Use 7-Zip (Windows) or p7zip (POSIX-like systems) to handle .7z
+    files.
+
+
+Q:  I have many .tar.7z files. Can I convert them to .tar.xz without
+    spending hours recompressing the data?
+
+A:  In the "extra" directory, there is a script named 7z2lzma.bash which
+    is able to convert some .7z files to the .lzma format (not .xz). It
+    needs the 7za (or 7z) command from p7zip. The script may silently
+    produce corrupt output if certain assumptions are not met, so
+    decompress the resulting .lzma file and compare it against the
+    original before deleting the original file!
+
+
+Q:  I have many .lzma files. Can I quickly convert them to the .xz format?
+
+A:  For now, no. Since XZ Utils supports the .lzma format, it's usually
+    not too bad to keep the old files in the old format. If you want to
+    do the conversion anyway, you need to decompress the .lzma files and
+    then recompress to the .xz format.
+
+    Technically, there is a way to make the conversion relatively fast
+    (roughly twice the time that normal decompression takes). Writing
+    such a tool would take quite a bit of time though, and would probably
+    be useful to only a few people. If you really want such a conversion
+    tool, contact Lasse Collin and offer some money.
+
+
+Q:  I have installed xz, but my tar doesn't recognize .tar.xz files.
+    How can I extract .tar.xz files?
+
+A:  xz -dc foo.tar.xz | tar xf -
+
+
+Q:  Can I recover parts of a broken .xz file (e.g. a corrupted CD-R)?
+
+A:  It may be possible if the file consists of multiple blocks, which
+    typically is not the case if the file was created in single-threaded
+    mode. There is no recovery program yet.
+
+
+Q:  Is (some part of) XZ Utils patented?
+
+A:  Lasse Collin is not aware of any patents that could affect XZ Utils.
+    However, due to the nature of software patents, it's not possible to
+    guarantee that XZ Utils isn't affected by any third party patent(s).
+
+
+Q:  Where can I find documentation about the file format and algorithms?
+
+A:  The .xz format is documented in xz-file-format.txt. It is a container
+    format only, and doesn't include descriptions of any non-trivial
+    filters.
+
+    Documenting LZMA and LZMA2 is planned, but for now, there is no other
+    documentation than the source code. Before you begin, you should know
+    the basics of LZ77 and range-coding algorithms. LZMA is based on LZ77,
+    but LZMA is a lot more complex. Range coding is used to compress
+    the final bitstream like Huffman coding is used in Deflate.
+
+
+Q:  I cannot find BCJ and BCJ2 filters. Don't they exist in liblzma?
+
+A:  BCJ filter is called "x86" in liblzma. BCJ2 is not included,
+    because it requires using more than one encoded output stream.
+
+
+Q:  I need to use a script that runs "xz -9". On a system with 256 MiB
+    of RAM, xz says that it cannot allocate memory. Can I make the
+    script work without modifying it?
+
+A:  Set a default memory usage limit for compression. You can do it e.g.
+    in a shell initialization script such as ~/.bashrc or /etc/profile:
+
+        XZ_DEFAULTS=--memlimit-compress=150MiB
+        export XZ_DEFAULTS
+
+    xz will then scale the compression settings down so that the given
+    memory usage limit is not reached. This way xz shouldn't run out
+    of memory.
+
+    Check also that memory-related resource limits are high enough.
+    On most systems, "ulimit -a" will show the current resource limits.
+
+
+Q:  How do I create files that can be decompressed with XZ Embedded?
+
+A:  See the documentation in XZ Embedded. In short, something like
+    this is a good start:
+
+        xz --check=crc32 --lzma2=preset=6e,dict=64KiB
+
+    Or if a BCJ filter is needed too, e.g. if compressing
+    a kernel image for PowerPC:
+
+        xz --check=crc32 --powerpc --lzma2=preset=6e,dict=64KiB
+
+    Adjust the dictionary size to get a good compromise between
+    compression ratio and decompressor memory usage. Note that
+    in single-call decompression mode of XZ Embedded, a big
+    dictionary doesn't increase memory usage.
+
+
+Q:  How is multi-threaded compression implemented in XZ Utils?
+
+A:  The simplest method is splitting the uncompressed data into blocks
+    and compressing them in parallel independent from each other.
+    This is currently the only threading method supported in XZ Utils.
+    Since the blocks are compressed independently, they can also be
+    decompressed independently. Together with the index feature in .xz,
+    this allows using threads to create .xz files for random-access
+    reading. This also makes threaded decompression possible.
+
+    The independent blocks method has a couple of disadvantages too. It
+    will compress worse than a single-block method. Often the difference
+    is not too big (maybe 1-2 %) but sometimes it can be too big. Also,
+    the memory usage of the compressor increases linearly when adding
+    threads.
+
+    At least two other threading methods are possible but these haven't
+    been implemented in XZ Utils:
+
+    Match finder parallelization has been in 7-Zip for ages. It doesn't
+    affect compression ratio or memory usage significantly. Among the
+    three threading methods, only this is useful when compressing small
+    files (files that are not significantly bigger than the dictionary).
+    Unfortunately this method scales only to about two CPU cores.
+
+    The third method is pigz-style threading (I use that name, because
+    pigz <https://www.zlib.net/pigz/> uses that method). It doesn't
+    affect compression ratio significantly and scales to many cores.
+    The memory usage scales linearly when threads are added. This isn't
+    significant with pigz, because Deflate uses only a 32 KiB dictionary,
+    but with LZMA2 the memory usage will increase dramatically just like
+    with the independent-blocks method. There is also a constant
+    computational overhead, which may make pigz-method a bit dull on
+    dual-core compared to the parallel match finder method, but with more
+    cores the overhead is not a big deal anymore.
+
+    Combining the threading methods will be possible and also useful.
+    For example, combining match finder parallelization with pigz-style
+    threading or independent-blocks-threading can cut the memory usage
+    by 50 %.
+
+
+Q:  I told xz to use many threads but it is using only one or two
+    processor cores. What is wrong?
+
+A:  Since multi-threaded compression is done by splitting the data into
+    blocks that are compressed individually, if the input file is too
+    small for the block size, then many threads cannot be used. The
+    default block size increases when the compression level is
+    increased. For example, xz -6 uses 8 MiB LZMA2 dictionary and
+    24 MiB blocks, and xz -9 uses 64 MiB LZMA dictionary and 192 MiB
+    blocks. If the input file is 100 MiB, xz -6 can use five threads
+    of which one will finish quickly as it has only 4 MiB to compress.
+    However, for the same file, xz -9 can only use one thread.
+
+    One can adjust block size with --block-size=SIZE but making the
+    block size smaller than LZMA2 dictionary is waste of RAM: using
+    xz -9 with 6 MiB blocks isn't any better than using xz -6 with
+    6 MiB blocks. The default settings use a block size bigger than
+    the LZMA2 dictionary size because this was seen as a reasonable
+    compromise between RAM usage and compression ratio.
+
+    When decompressing, the ability to use threads depends on how the
+    file was created. If it was created in multi-threaded mode then
+    it can be decompressed in multi-threaded mode too if there are
+    multiple blocks in the file.
+
+
+Q:  How do I build a program that needs liblzmadec (lzmadec.h)?
+
+A:  liblzmadec is part of LZMA Utils. XZ Utils has liblzma, but no
+    liblzmadec. The code using liblzmadec should be ported to use
+    liblzma instead. If you cannot or don't want to do that, download
+    LZMA Utils from <https://tukaani.org/lzma/>.
+
+
+Q:  The default build of liblzma is too big. How can I make it smaller?
+
+A:  Give --enable-small to the configure script. Use also appropriate
+    --enable or --disable options to include only those filter encoders
+    and decoders and integrity checks that you actually need. Use
+    CFLAGS=-Os (with GCC) or equivalent to tell your compiler to optimize
+    for size. See INSTALL for information about configure options.
+
+    If the result is still too big, take a look at XZ Embedded. It is
+    a separate project, which provides a limited but significantly
+    smaller XZ decoder implementation than XZ Utils. You can find it
+    at <https://tukaani.org/xz/embedded.html>.

+
+History of LZMA Utils and XZ Utils
+==================================
+
+Tukaani distribution
+
+    In 2005, there was a small group working on the Tukaani distribution,
+    which was a Slackware fork. One of the project's goals was to fit the
+    distro on a single 700 MiB ISO-9660 image. Using LZMA instead of gzip
+    helped a lot. Roughly speaking, one could fit data that took 1000 MiB
+    in gzipped form into 700 MiB with LZMA. Naturally, the compression
+    ratio varied across packages, but this was what we got on average.
+
+    Slackware packages have traditionally had .tgz as the filename suffix,
+    which is an abbreviation of .tar.gz. A logical naming for LZMA
+    compressed packages was .tlz, being an abbreviation of .tar.lzma.
+
+    At the end of the year 2007, there was no distribution under the
+    Tukaani project anymore, but development of LZMA Utils was kept going.
+    Still, there were .tlz packages around, because at least Vector Linux
+    (a Slackware based distribution) used LZMA for its packages.
+
+    First versions of the modified pkgtools used the LZMA_Alone tool from
+    Igor Pavlov's LZMA SDK as is. It was fine, because users wouldn't need
+    to interact with LZMA_Alone directly. But people soon wanted to use
+    LZMA for other files too, and the interface of LZMA_Alone wasn't
+    comfortable for those used to gzip and bzip2.
+
+
+First steps of LZMA Utils
+
+    The first version of LZMA Utils (4.22.0) included a shell script called
+    lzmash. It was a wrapper that had a gzip-like command-line interface. It
+    used the LZMA_Alone tool from LZMA SDK to do all the real work. zgrep,
+    zdiff, and related scripts from gzip were adapted to work with LZMA and
+    were part of the first LZMA Utils release too.
+
+    LZMA Utils 4.22.0 included also lzmadec, which was a small (less than
+    10 KiB) decoder-only command-line tool. It was written on top of the
+    decoder-only C code found from the LZMA SDK. lzmadec was convenient in
+    situations where LZMA_Alone (a few hundred KiB) would be too big.
+
+    lzmash and lzmadec were written by Lasse Collin.
+
+
+Second generation
+
+    The lzmash script was an ugly and not very secure hack. The last
+    version of LZMA Utils to use lzmash was 4.27.1.
+
+    LZMA Utils 4.32.0beta1 introduced a new lzma command-line tool written
+    by Ville Koskinen. It was written in C++, and used the encoder and
+    decoder from C++ LZMA SDK with some little modifications. This tool
+    replaced both the lzmash script and the LZMA_Alone command-line tool
+    in LZMA Utils.
+
+    Introducing this new tool caused some temporary incompatibilities,
+    because the LZMA_Alone executable was simply named lzma like the new
+    command-line tool, but they had a completely different command-line
+    interface. The file format was still the same.
+
+    Lasse wrote liblzmadec, which was a small decoder-only library based
+    on the C code found from LZMA SDK. liblzmadec had an API similar to
+    zlib, although there were some significant differences, which made it
+    non-trivial to use it in some applications designed for zlib and
+    libbzip2.
+
+    The lzmadec command-line tool was converted to use liblzmadec.
+
+    Alexandre Sauvé helped converting the build system to use GNU
+    Autotools. This made it easier to test for certain less portable
+    features needed by the new command-line tool.
+
+    Since the new command-line tool never got completely finished (for
+    example, it didn't support the LZMA_OPT environment variable), the
+    intent was to not call 4.32.x stable. Similarly, liblzmadec wasn't
+    polished, but appeared to work well enough, so some people started
+    using it too.
+
+    Because the development of the third generation of LZMA Utils was
+    delayed considerably (3-4 years), the 4.32.x branch had to be kept
+    maintained. It got some bug fixes now and then, and finally it was
+    decided to call it stable, although most of the missing features were
+    never added.
+
+
+File format problems
+
+    The file format used by LZMA_Alone was primitive. It was designed with
+    embedded systems in mind, and thus provided only a minimal set of
+    features. The two biggest problems for non-embedded use were the lack
+    of magic bytes and an integrity check.
+
+    Igor and Lasse started developing a new file format with some help
+    from Ville Koskinen. Also Mark Adler, Mikko Pouru, H. Peter Anvin,
+    and Lars Wirzenius helped with some minor things at some point of the
+    development. Designing the new format took quite a long time (actually,
+    too long a time would be a more appropriate expression). It was mostly
+    because Lasse was quite slow at getting things done due to personal
+    reasons.
+
+    Originally the new format was supposed to use the same .lzma suffix
+    that was already used by the old file format. Switching to the new
+    format wouldn't have caused much trouble when the old format wasn't
+    used by many people. But since the development of the new format took
+    such a long time, the old format got quite popular, and it was decided
+    that the new file format must use a different suffix.
+
+    It was decided to use .xz as the suffix of the new file format. The
+    first stable .xz file format specification was finally released in
+    December 2008. In addition to fixing the most obvious problems of
+    the old .lzma format, the .xz format added some new features like
+    support for multiple filters (compression algorithms), filter chaining
+    (like piping on the command line), and limited random-access reading.
+
+    Currently the primary compression algorithm used in .xz is LZMA2.
+    It is an extension on top of the original LZMA to fix some practical
+    problems: LZMA2 adds support for flushing the encoder, uncompressed
+    chunks, eases stateful decoder implementations, and improves support
+    for multithreading. Since LZMA2 is better than the original LZMA, the
+    original LZMA is not supported in .xz.
+
+
+Transition to XZ Utils
+
+    The early versions of XZ Utils were called LZMA Utils. The first
+    releases were 4.42.0alphas. They dropped the rest of the C++ LZMA SDK.
+    The code was still directly based on LZMA SDK but ported to C and
+    converted from a callback API to a stateful API. Later, Igor Pavlov
+    made a C version of the LZMA encoder too; these ports from C++ to C
+    were independent in LZMA SDK and LZMA Utils.
+
+    The core of the new LZMA Utils was liblzma, a compression library with
+    a zlib-like API. liblzma supported both the old and new file format.
+    The gzip-like lzma command-line tool was rewritten to use liblzma.
+
+    The new LZMA Utils code base was renamed to XZ Utils when the name
+    of the new file format had been decided. The liblzma compression
+    library retained its name though, because changing it would have
+    caused unnecessary breakage in applications already using the early
+    liblzma snapshots.
+
+    The xz command-line tool can emulate the gzip-like lzma tool by
+    creating appropriate symlinks (e.g. lzma -> xz). Thus, practically
+    all scripts using the lzma tool from LZMA Utils will work as is with
+    XZ Utils (and will keep using the old .lzma format). Still, the .lzma
+    format is more or less deprecated. XZ Utils will keep supporting it,
+    but new applications should use the .xz format, and migrating old
+    applications to .xz is often a good idea too.

+0. Preface
+
+        This document describes the .lzma file format, which is
+        sometimes also called LZMA_Alone format. It is a legacy file
+        format, which is being or has been replaced by the .xz format.
+        The MIME type of the .lzma format is `application/x-lzma'.
+
+        The most commonly used software to handle .lzma files are
+        LZMA SDK, LZMA Utils, 7-Zip, and XZ Utils. This document
+        describes some of the differences between these implementations
+        and gives hints what subset of the .lzma format is the most
+        portable.

+
+        The .lzma format file consist of 13-byte Header followed by
+        the LZMA Compressed Data.
+
+        Unlike the .gz, .bz2, and .xz formats, it is not possible to
+        concatenate multiple .lzma files as is and expect the
+        decompression tool to decode the resulting file as if it were
+        a single .lzma file.
+
+        For example, the command line tools from LZMA Utils and
+        LZMA SDK silently ignore all the data after the first .lzma
+        stream. In contrast, the command line tool from XZ Utils
+        considers the .lzma file to be corrupt if there is data after
+        the first .lzma stream.

+        +------------+----+----+----+----+--+--+--+--+--+--+--+--+
+
+
+1.1.1. Properties
+
+        The Properties field contains three properties. An abbreviation
+        is given in parentheses, followed by the value range of the
+        property. The field consists of
+
+            1) the number of literal context bits (lc, [0, 8]);
+            2) the number of literal position bits (lp, [0, 4]); and
+            3) the number of position bits (pb, [0, 4]).
+
+        The properties are encoded using the following formula:
+
+            Properties = (pb * 5 + lp) * 9 + lc
+
+        The following C code illustrates a straightforward way to
+        decode the Properties field:
+
+            uint8_t lc, lp, pb;
+            uint8_t prop = get_lzma_properties();
+            if (prop > (4 * 5 + 4) * 9 + 8)
+                return LZMA_PROPERTIES_ERROR;
+
+            pb = prop / (9 * 5);
+            prop -= pb * 9 * 5;
+            lp = prop / 9;
+            lc = prop - lp * 9;
+
+        XZ Utils has an additional requirement: lc + lp <= 4. Files
+        which don't follow this requirement cannot be decompressed
+        with XZ Utils. Usually this isn't a problem since the most
+        common lc/lp/pb values are 3/0/2. It is the only lc/lp/pb
+        combination that the files created by LZMA Utils can have,
+        but LZMA Utils can decompress files with any lc/lp/pb.
+
+
+1.1.2. Dictionary Size
+
+        Dictionary Size is stored as an unsigned 32-bit little endian
+        integer. Any 32-bit value is possible, but for maximum
+        portability, only sizes of 2^n and 2^n + 2^(n-1) should be
+        used.
+
+        LZMA Utils creates only files with dictionary size 2^n,
+        16 <= n <= 25. LZMA Utils can decompress files with any
+        dictionary size.
+
+        XZ Utils creates and decompresses .lzma files only with
+        dictionary sizes 2^n and 2^n + 2^(n-1). If some other
+        dictionary size is specified when compressing, the value
+        stored in the Dictionary Size field is a rounded up, but the
+        specified value is still used in the actual compression code.
+
+
+1.1.3. Uncompressed Size
+
+        Uncompressed Size is stored as unsigned 64-bit little endian
+        integer. A special value of 0xFFFF_FFFF_FFFF_FFFF indicates
+        that Uncompressed Size is unknown. End of Payload Marker (*)
+        is used if Uncompressed Size is unknown. End of Payload Marker
+        is allowed but rarely used if Uncompressed Size is known.
+        XZ Utils 5.2.5 and older don't support .lzma files that have
+        End of Payload Marker together with a known Uncompressed Size.
+
+        XZ Utils rejects files whose Uncompressed Size field specifies
+        a known size that is 256 GiB or more. This is to reject false
+        positives when trying to guess if the input file is in the
+        .lzma format. When Uncompressed Size is unknown, there is no
+        limit for the uncompressed size of the file.
+
+        (*) Some tools use the term End of Stream (EOS) marker
+            instead of End of Payload Marker.

+NAME
+       lzmainfo - show information stored in the .lzma file header
+
+SYNOPSIS
+       lzmainfo [--help] [--version] [file...]
+
+DESCRIPTION
+       lzmainfo  shows  information stored in the .lzma file header.  It reads
+       the first 13 bytes from the specified file,  decodes  the  header,  and
+       prints it to standard output in human readable format.  If no files are
+       given or file is -, standard input is read.
+
+       Usually the most interesting information is the uncompressed  size  and
+       the  dictionary  size.  Uncompressed size can be shown only if the file
+       is in the non-streamed .lzma format variant.  The amount of memory  re-
+       quired to decompress the file is a few dozen kilobytes plus the dictio-
+       nary size.
+
+       lzmainfo is included in XZ Utils primarily for  backward  compatibility
+       with LZMA Utils.
+
+EXIT STATUS
+       0      All is good.
+
+       1      An error occurred.
+
+BUGS
+       lzmainfo  uses  MB  while the correct suffix would be MiB (2^20 bytes).
+       This is to keep the output compatible with LZMA Utils.

+NAME
+       xz,  unxz,  xzcat, lzma, unlzma, lzcat - Compress or decompress .xz and
+       .lzma files
+
+SYNOPSIS
+       xz [option...]  [file...]
+
+COMMAND ALIASES
+       unxz is equivalent to xz --decompress.
+       xzcat is equivalent to xz --decompress --stdout.
+       lzma is equivalent to xz --format=lzma.
+       unlzma is equivalent to xz --format=lzma --decompress.
+       lzcat is equivalent to xz --format=lzma --decompress --stdout.
+
+       When writing scripts that need to decompress files, it  is  recommended
+       to  always use the name xz with appropriate arguments (xz -d or xz -dc)
+       instead of the names unxz and xzcat.
+
+DESCRIPTION
+       xz is a general-purpose data compression tool with command line  syntax
+       similar  to  gzip(1)  and  bzip2(1).  The native file format is the .xz
+       format, but the legacy .lzma format used by LZMA  Utils  and  raw  com-
+       pressed  streams  with  no container format headers are also supported.
+       In addition, decompression of the .lz format used by lzip is supported.
+
+       xz compresses or decompresses each file according to the selected oper-
+       ation mode.  If no files are given or file is -, xz reads from standard
+       input and writes the processed data to standard output.  xz will refuse
+       (display  an error and skip the file) to write compressed data to stan-
+       dard output if it is a terminal.  Similarly, xz  will  refuse  to  read
+       compressed data from standard input if it is a terminal.
+
+       Unless  --stdout  is specified, files other than - are written to a new
+       file whose name is derived from the source file name:
+
+       o  When compressing, the suffix of  the  target  file  format  (.xz  or
+          .lzma)  is  appended  to the source filename to get the target file-
+          name.
+
+       o  When decompressing, the .xz, .lzma, or .lz suffix  is  removed  from
+          the  filename  to  get  the target filename.  xz also recognizes the
+          suffixes .txz and .tlz, and replaces them with the .tar suffix.
+
+       If the target file already exists, an error is displayed and  the  file
+       is skipped.
+
+       Unless  writing  to standard output, xz will display a warning and skip
+       the file if any of the following applies:
+
+       o  File is not a regular file.  Symbolic links are  not  followed,  and
+          thus they are not considered to be regular files.
+
+       o  File has more than one hard link.
+
+       o  File has setuid, setgid, or sticky bit set.
+
+       o  The  operation  mode  is  set to compress and the file already has a
+          suffix of the target file format (.xz or .txz  when  compressing  to
+          the .xz format, and .lzma or .tlz when compressing to the .lzma for-
+          mat).
+
+       o  The operation mode is set to decompress and the file doesn't have  a
+          suffix of any of the supported file formats (.xz, .txz, .lzma, .tlz,
+          or .lz).
+
+       After successfully compressing or decompressing the file, xz copies the
+       owner,  group, permissions, access time, and modification time from the
+       source file to the target file.  If copying the group fails,  the  per-
+       missions are modified so that the target file doesn't become accessible
+       to users who didn't have permission to  access  the  source  file.   xz
+       doesn't support copying other metadata like access control lists or ex-
+       tended attributes yet.
+
+       Once the target file has been successfully closed, the source  file  is
+       removed  unless --keep was specified.  The source file is never removed
+       if the output is written to standard output or if an error occurs.
+
+       Sending SIGINFO or SIGUSR1 to the xz process makes  it  print  progress
+       information  to  standard  error.  This has only limited use since when
+       standard error is a terminal, using --verbose will display an automati-
+       cally updating progress indicator.
+
+   Memory usage
+       The  memory  usage of xz varies from a few hundred kilobytes to several
+       gigabytes depending on the compression  settings.   The  settings  used
+       when compressing a file determine the memory requirements of the decom-
+       pressor.  Typically the decompressor needs 5 % to 20 % of the amount of
+       memory that the compressor needed when creating the file.  For example,
+       decompressing a file created with xz -9 currently  requires  65 MiB  of
+       memory.   Still,  it is possible to have .xz files that require several
+       gigabytes of memory to decompress.
+
+       Especially users of older systems may  find  the  possibility  of  very
+       large  memory  usage  annoying.  To prevent uncomfortable surprises, xz
+       has a built-in memory usage limiter,  which  is  disabled  by  default.
+       While  some operating systems provide ways to limit the memory usage of
+       processes, relying on it wasn't deemed to be flexible enough (for exam-
+       ple, using ulimit(1) to limit virtual memory tends to cripple mmap(2)).
+
+       The  memory  usage  limiter can be enabled with the command line option
+       --memlimit=limit.  Often it is more convenient to enable the limiter by
+       default  by  setting the environment variable XZ_DEFAULTS, for example,
+       XZ_DEFAULTS=--memlimit=150MiB.  It is possible to set the limits  sepa-
+       rately  for  compression  and  decompression  by  using --memlimit-com-
+       press=limit and --memlimit-decompress=limit.  Using these  two  options
+       outside  XZ_DEFAULTS is rarely useful because a single run of xz cannot
+       do both compression  and  decompression  and  --memlimit=limit  (or  -M
+       limit) is shorter to type on the command line.
+
+       If  the specified memory usage limit is exceeded when decompressing, xz
+       will display an error and decompressing the file  will  fail.   If  the
+       limit  is  exceeded when compressing, xz will try to scale the settings
+       down so that the limit is no longer exceeded (except when using  --for-
+       mat=raw  or --no-adjust).  This way the operation won't fail unless the
+       limit is very small.  The scaling of the settings is done in steps that
+       don't match the compression level presets, for example, if the limit is
+       only slightly less than the amount required for  xz  -9,  the  settings
+       will be scaled down only a little, not all the way down to xz -8.
+
+   Concatenation and padding with .xz files
+       It is possible to concatenate .xz files as is.  xz will decompress such
+       files as if they were a single .xz file.
+
+       It is possible to insert padding between the concatenated parts or  af-
+       ter the last part.  The padding must consist of null bytes and the size
+       of the padding must be a multiple of four bytes.  This can  be  useful,
+       for  example,  if the .xz file is stored on a medium that measures file
+       sizes in 512-byte blocks.
+
+       Concatenation and padding are not  allowed  with  .lzma  files  or  raw
+       streams.
+
+OPTIONS
+   Integer suffixes and special values
+       In  most places where an integer argument is expected, an optional suf-
+       fix is supported to easily indicate large integers.  There must  be  no
+       space between the integer and the suffix.
+
+       KiB    Multiply  the integer by 1,024 (2^10).  Ki, k, kB, K, and KB are
+              accepted as synonyms for KiB.
+
+       MiB    Multiply the integer by 1,048,576 (2^20).  Mi, m, M, and MB  are
+              accepted as synonyms for MiB.
+
+       GiB    Multiply  the integer by 1,073,741,824 (2^30).  Gi, g, G, and GB
+              are accepted as synonyms for GiB.
+
+       The special value max can be used to indicate the maximum integer value
+       supported by the option.
+
+   Operation mode
+       If  multiple  operation  mode options are given, the last one takes ef-
+       fect.
+
+       -z, --compress
+              Compress.  This is the default operation mode when no  operation
+              mode  option is specified and no other operation mode is implied
+              from the command name (for example, unxz implies --decompress).
+
+       -d, --decompress, --uncompress
+              Decompress.
+
+       -t, --test
+              Test the integrity of compressed files.  This option is  equiva-
+              lent  to --decompress --stdout except that the decompressed data
+              is discarded instead of being written to  standard  output.   No
+              files are created or removed.
+
+       -l, --list
+              Print  information about compressed files.  No uncompressed out-
+              put is produced, and no files are created or removed.   In  list
+              mode,  the program cannot read the compressed data from standard
+              input or from other unseekable sources.
+
+              The default listing shows basic  information  about  files,  one
+              file  per  line.  To get more detailed information, use also the
+              --verbose option.  For  even  more  information,  use  --verbose
+              twice,  but  note that this may be slow, because getting all the
+              extra information requires many seeks.   The  width  of  verbose
+              output exceeds 80 characters, so piping the output to, for exam-
+              ple, less -S may  be  convenient  if  the  terminal  isn't  wide
+              enough.
+
+              The  exact output may vary between xz versions and different lo-
+              cales.  For machine-readable output, --robot  --list  should  be
+              used.
+
+   Operation modifiers
+       -k, --keep
+              Don't delete the input files.
+
+              Since xz 5.2.6, this option also makes xz compress or decompress
+              even if the input is a symbolic link to a regular file, has more
+              than  one  hard  link,  or has the setuid, setgid, or sticky bit
+              set.  The setuid, setgid, and sticky bits are not copied to  the
+              target  file.   In  earlier  versions  this  was  only done with
+              --force.
+
+       -f, --force
+              This option has several effects:
+
+              o  If the target file already exists, delete it before compress-
+                 ing or decompressing.
+
+              o  Compress  or  decompress even if the input is a symbolic link
+                 to a regular file, has more than one hard link,  or  has  the
+                 setuid,  setgid,  or sticky bit set.  The setuid, setgid, and
+                 sticky bits are not copied to the target file.
+
+              o  When used with --decompress --stdout and xz cannot  recognize
+                 the  type  of  the source file, copy the source file as is to
+                 standard output.  This allows xzcat --force to be  used  like
+                 cat(1) for files that have not been compressed with xz.  Note
+                 that in future, xz might support new compressed file formats,
+                 which  may  make xz decompress more types of files instead of
+                 copying them as is to standard output.   --format=format  can
+                 be  used to restrict xz to decompress only a single file for-
+                 mat.
+
+       -c, --stdout, --to-stdout
+              Write the compressed or decompressed data to standard output in-
+              stead of a file.  This implies --keep.
+
+       --single-stream
+              Decompress only the first .xz stream, and silently ignore possi-
+              ble remaining input data following the  stream.   Normally  such
+              trailing garbage makes xz display an error.
+
+              xz  never  decompresses more than one stream from .lzma files or
+              raw streams, but this option still makes xz ignore the  possible
+              trailing data after the .lzma file or raw stream.
+
+              This  option has no effect if the operation mode is not --decom-
+              press or --test.
+
+       --no-sparse
+              Disable creation of sparse files.  By default, if  decompressing
+              into a regular file, xz tries to make the file sparse if the de-
+              compressed data contains long sequences  of  binary  zeros.   It
+              also  works  when writing to standard output as long as standard
+              output is connected to a regular  file  and  certain  additional
+              conditions  are  met to make it safe.  Creating sparse files may
+              save disk space and speed up the decompression by  reducing  the
+              amount of disk I/O.
+
+       -S .suf, --suffix=.suf
+              When compressing, use .suf as the suffix for the target file in-
+              stead of .xz or .lzma.  If not writing to  standard  output  and
+              the  source  file already has the suffix .suf, a warning is dis-
+              played and the file is skipped.
+
+              When decompressing, recognize files with the suffix .suf in  ad-
+              dition  to files with the .xz, .txz, .lzma, .tlz, or .lz suffix.
+              If the source file has the suffix .suf, the suffix is removed to
+              get the target filename.
+
+              When  compressing  or  decompressing raw streams (--format=raw),
+              the suffix must always be specified unless writing  to  standard
+              output, because there is no default suffix for raw streams.
+
+       --files[=file]
+              Read  the  filenames  to  process from file; if file is omitted,
+              filenames are read from standard input.  Filenames must be  ter-
+              minated  with  the  newline character.  A dash (-) is taken as a
+              regular filename; it doesn't mean standard input.  If  filenames
+              are given also as command line arguments, they are processed be-
+              fore the filenames read from file.
+
+       --files0[=file]
+              This is identical to --files[=file] except  that  each  filename
+              must be terminated with the null character.
+
+   Basic file format and compression options
+       -F format, --format=format
+              Specify the file format to compress or decompress:
+
+              auto   This  is  the default.  When compressing, auto is equiva-
+                     lent to xz.  When decompressing, the format of the  input
+                     file  is  automatically  detected.  Note that raw streams
+                     (created with --format=raw) cannot be auto-detected.
+
+              xz     Compress to the .xz file format, or accept only .xz files
+                     when decompressing.
+
+              lzma, alone
+                     Compress  to the legacy .lzma file format, or accept only
+                     .lzma files when  decompressing.   The  alternative  name
+                     alone  is  provided for backwards compatibility with LZMA
+                     Utils.
+
+              lzip   Accept only .lz files when decompressing.  Compression is
+                     not supported.
+
+                     The .lz format version 0 and the unextended version 1 are
+                     supported.  Version 0 files were produced by lzip 1.3 and
+                     older.   Such  files  aren't common but may be found from
+                     file archives as a few source packages were  released  in
+                     this  format.   People  might  have old personal files in
+                     this format too.  Decompression support  for  the  format
+                     version 0 was removed in lzip 1.18.
+
+                     lzip  1.4 and later create files in the format version 1.
+                     The sync flush marker extension to the format  version  1
+                     was added in lzip 1.6.  This extension is rarely used and
+                     isn't supported by xz (diagnosed as corrupt input).
+
+              raw    Compress or uncompress a raw stream (no  headers).   This
+                     is meant for advanced users only.  To decode raw streams,
+                     you need use --format=raw and explicitly specify the fil-
+                     ter  chain,  which normally would have been stored in the
+                     container headers.
+
+       -C check, --check=check
+              Specify the type of the integrity check.  The  check  is  calcu-
+              lated  from  the  uncompressed  data and stored in the .xz file.
+              This option has an effect only when  compressing  into  the  .xz
+              format;  the .lzma format doesn't support integrity checks.  The
+              integrity check (if any) is verified when the .xz file is decom-
+              pressed.
+
+              Supported check types:
+
+              none   Don't  calculate an integrity check at all.  This is usu-
+                     ally a bad idea.  This can be useful  when  integrity  of
+                     the data is verified by other means anyway.
+
+              crc32  Calculate  CRC32  using  the  polynomial  from IEEE-802.3
+                     (Ethernet).
+
+              crc64  Calculate CRC64 using the polynomial from ECMA-182.  This
+                     is the default, since it is slightly better than CRC32 at
+                     detecting damaged files and the speed difference is  neg-
+                     ligible.
+
+              sha256 Calculate  SHA-256.   This  is somewhat slower than CRC32
+                     and CRC64.
+
+              Integrity of the .xz headers is always verified with CRC32.   It
+              is not possible to change or disable it.
+
+       --ignore-check
+              Don't verify the integrity check of the compressed data when de-
+              compressing.  The CRC32 values in the .xz headers will still  be
+              verified normally.
+
+              Do not use this option unless you know what you are doing.  Pos-
+              sible reasons to use this option:
+
+              o  Trying to recover data from a corrupt .xz file.
+
+              o  Speeding up decompression.  This matters mostly with  SHA-256
+                 or with files that have compressed extremely well.  It's rec-
+                 ommended to not use this option for this purpose  unless  the
+                 file integrity is verified externally in some other way.
+
+       -0 ... -9
+              Select  a compression preset level.  The default is -6.  If mul-
+              tiple preset levels are specified, the last  one  takes  effect.
+              If  a  custom filter chain was already specified, setting a com-
+              pression preset level clears the custom filter chain.
+
+              The differences between the presets are  more  significant  than
+              with  gzip(1)  and  bzip2(1).  The selected compression settings
+              determine the memory requirements of the decompressor, thus  us-
+              ing  a too high preset level might make it painful to decompress
+              the file on an old system with little RAM.   Specifically,  it's
+              not  a  good idea to blindly use -9 for everything like it often
+              is with gzip(1) and bzip2(1).
+
+              -0 ... -3
+                     These are somewhat fast presets.  -0 is sometimes  faster
+                     than  gzip  -9 while compressing much better.  The higher
+                     ones often have speed comparable to bzip2(1) with  compa-
+                     rable  or  better compression ratio, although the results
+                     depend a lot on the type of data being compressed.
+
+              -4 ... -6
+                     Good to very good compression while keeping  decompressor
+                     memory  usage reasonable even for old systems.  -6 is the
+                     default, which is usually a good choice for  distributing
+                     files that need to be decompressible even on systems with
+                     only 16 MiB RAM.  (-5e or -6e may  be  worth  considering
+                     too.  See --extreme.)
+
+              -7 ... -9
+                     These  are  like -6 but with higher compressor and decom-
+                     pressor memory requirements.  These are useful only  when
+                     compressing  files bigger than 8 MiB, 16 MiB, and 32 MiB,
+                     respectively.
+
+              On the same hardware, the decompression speed is approximately a
+              constant  number  of  bytes  of  compressed data per second.  In
+              other words, the better the compression, the faster  the  decom-
+              pression  will  usually  be.  This also means that the amount of
+              uncompressed output produced per second can vary a lot.
+
+              The following table summarises the features of the presets:
+
+                     Preset   DictSize   CompCPU   CompMem   DecMem

+
+              Column descriptions:
+
+              o  DictSize is the LZMA2 dictionary size.  It is waste of memory
+                 to  use a dictionary bigger than the size of the uncompressed
+                 file.  This is why it is good to avoid using the  presets  -7
+                 ...  -9 when there's no real need for them.  At -6 and lower,
+                 the amount of memory wasted is usually low enough to not mat-
+                 ter.
+
+              o  CompCPU  is a simplified representation of the LZMA2 settings
+                 that affect compression speed.  The dictionary  size  affects
+                 speed too, so while CompCPU is the same for levels -6 ... -9,
+                 higher levels still tend to be a little slower.  To get  even
+                 slower and thus possibly better compression, see --extreme.
+
+              o  CompMem  contains  the  compressor memory requirements in the
+                 single-threaded mode.  It may vary slightly between  xz  ver-
+                 sions.   Memory  requirements  of  some  of the future multi-
+                 threaded modes may be dramatically higher than  that  of  the
+                 single-threaded mode.
+
+              o  DecMem  contains  the decompressor memory requirements.  That
+                 is, the compression settings determine  the  memory  require-
+                 ments of the decompressor.  The exact decompressor memory us-
+                 age is slightly more than the LZMA2 dictionary size, but  the
+                 values  in  the  table  have been rounded up to the next full
+                 MiB.
+
+       -e, --extreme
+              Use a slower variant of the selected  compression  preset  level
+              (-0 ... -9) to hopefully get a little bit better compression ra-
+              tio, but with bad luck this can also make it worse.   Decompres-
+              sor  memory  usage  is not affected, but compressor memory usage
+              increases a little at preset levels -0 ... -3.
+
+              Since there are two presets  with  dictionary  sizes  4 MiB  and
+              8 MiB,  the  presets  -3e  and  -5e use slightly faster settings
+              (lower CompCPU) than -4e and -6e, respectively.  That way no two
+              presets are identical.
+
+                     Preset   DictSize   CompCPU   CompMem   DecMem
+                      -0e     256 KiB       8        4 MiB    1 MiB
+                      -1e       1 MiB       8       13 MiB    2 MiB
+                      -2e       2 MiB       8       25 MiB    3 MiB
+                      -3e       4 MiB       7       48 MiB    5 MiB
+                      -4e       4 MiB       8       48 MiB    5 MiB
+                      -5e       8 MiB       7       94 MiB    9 MiB
+                      -6e       8 MiB       8       94 MiB    9 MiB
+                      -7e      16 MiB       8      186 MiB   17 MiB
+                      -8e      32 MiB       8      370 MiB   33 MiB
+                      -9e      64 MiB       8      674 MiB   65 MiB
+
+              For  example,  there  are a total of four presets that use 8 MiB
+              dictionary, whose order from the fastest to the slowest  is  -5,
+              -6, -5e, and -6e.
+
+       --fast
+       --best These  are  somewhat  misleading  aliases for -0 and -9, respec-
+              tively.  These are provided  only  for  backwards  compatibility
+              with LZMA Utils.  Avoid using these options.
+
+       --block-size=size
+              When  compressing  to  the .xz format, split the input data into
+              blocks of size bytes.  The blocks are  compressed  independently
+              from each other, which helps with multi-threading and makes lim-
+              ited random-access decompression possible.  This option is typi-
+              cally  used to override the default block size in multi-threaded
+              mode, but this option can be used in single-threaded mode too.
+
+              In multi-threaded mode about three times size bytes will be  al-
+              located  in each thread for buffering input and output.  The de-
+              fault size is three times the LZMA2 dictionary size  or  1  MiB,
+              whichever is more.  Typically a good value is 2-4 times the size
+              of the LZMA2 dictionary or at least 1 MiB.  Using size less than
+              the LZMA2 dictionary size is waste of RAM because then the LZMA2
+              dictionary buffer will never get fully used.  The sizes  of  the
+              blocks  are  stored in the block headers, which a future version
+              of xz will use for multi-threaded decompression.
+
+              In single-threaded mode no block splitting is done  by  default.
+              Setting this option doesn't affect memory usage.  No size infor-
+              mation is stored in block headers, thus files created in single-
+              threaded  mode  won't  be  identical  to files created in multi-
+              threaded mode.  The lack of size information also means  that  a
+              future  version  of  xz  won't  be  able decompress the files in
+              multi-threaded mode.
+
+       --block-list=sizes
+              When compressing to the .xz format, start a new block after  the
+              given intervals of uncompressed data.
+
+              The  uncompressed  sizes of the blocks are specified as a comma-
+              separated list.  Omitting a size (two or more  consecutive  com-
+              mas) is a shorthand to use the size of the previous block.
+
+              If  the  input  file  is  bigger than the sum of sizes, the last
+              value in sizes is repeated until the end of the file.  A special
+              value  of  0  may be used as the last value to indicate that the
+              rest of the file should be encoded as a single block.
+
+              If one specifies sizes that exceed the encoder's block size (ei-
+              ther  the  default value in threaded mode or the value specified
+              with --block-size=size),  the  encoder  will  create  additional
+              blocks while keeping the boundaries specified in sizes.  For ex-
+              ample,      if      one       specifies       --block-size=10MiB
+              --block-list=5MiB,10MiB,8MiB,12MiB,24MiB  and  the input file is
+              80 MiB, one will get 11 blocks: 5, 10, 8, 10, 2, 10, 10, 4,  10,
+              10, and 1 MiB.
+
+              In multi-threaded mode the sizes of the blocks are stored in the
+              block headers.  This isn't done in single-threaded mode, so  the
+              encoded  output won't be identical to that of the multi-threaded
+              mode.
+
+       --flush-timeout=timeout
+              When compressing, if more than timeout milliseconds (a  positive
+              integer)  has  passed  since the previous flush and reading more
+              input would block, all the pending input data  is  flushed  from
+              the  encoder  and made available in the output stream.  This can
+              be useful if xz is used to compress data that is streamed over a
+              network.   Small  timeout  values make the data available at the
+              receiving end with a small delay, but large timeout values  give
+              better compression ratio.
+
+              This  feature  is disabled by default.  If this option is speci-
+              fied more than once, the last one  takes  effect.   The  special
+              timeout  value  of 0 can be used to explicitly disable this fea-
+              ture.
+
+              This feature is not available on non-POSIX systems.

+              This feature is still experimental.  Currently xz is  unsuitable
+              for  decompressing  the  stream  in real time due to how xz does
+              buffering.
+
+       --memlimit-compress=limit
+              Set a memory usage limit for compression.   If  this  option  is
+              specified multiple times, the last one takes effect.
+
+              If the compression settings exceed the limit, xz will attempt to
+              adjust the settings downwards so that the limit is no longer ex-
+              ceeded  and display a notice that automatic adjustment was done.
+              The adjustments are done in this order: reducing the  number  of
+              threads, switching to single-threaded mode if even one thread in
+              multi-threaded mode exceeds the limit, and finally reducing  the
+              LZMA2 dictionary size.
+
+              When  compressing  with  --format=raw or if --no-adjust has been
+              specified, only the number of threads may be  reduced  since  it
+              can be done without affecting the compressed output.
+
+              If  the  limit cannot be met even with the adjustments described
+              above, an error is displayed and xz will exit with  exit  status
+              1.
+
+              The limit can be specified in multiple ways:
+
+              o  The  limit can be an absolute value in bytes.  Using an inte-
+                 ger suffix like MiB can be useful.  Example:  --memlimit-com-
+                 press=80MiB
+
+              o  The  limit can be specified as a percentage of total physical
+                 memory (RAM).  This can be useful especially when setting the
+                 XZ_DEFAULTS  environment  variable  in a shell initialization
+                 script that is shared between different computers.  That  way
+                 the  limit  is automatically bigger on systems with more mem-
+                 ory.  Example: --memlimit-compress=70%
+
+              o  The limit can be reset back to its default value  by  setting
+                 it  to  0.  This is currently equivalent to setting the limit
+                 to max (no memory usage limit).
+
+              For 32-bit xz there is a special case: if  the  limit  would  be
+              over 4020 MiB, the limit is set to 4020 MiB.  On MIPS32 2000 MiB
+              is used instead.  (The values 0 and max aren't affected by this.
+              A similar feature doesn't exist for decompression.)  This can be
+              helpful when a 32-bit executable has  access  to  4 GiB  address
+              space  (2  GiB on MIPS32) while hopefully doing no harm in other
+              situations.
+
+              See also the section Memory usage.
+
+       --memlimit-decompress=limit
+              Set a memory usage limit for decompression.  This  also  affects
+              the  --list  mode.  If the operation is not possible without ex-
+              ceeding the limit, xz will display an  error  and  decompressing
+              the  file will fail.  See --memlimit-compress=limit for possible
+              ways to specify the limit.
+
+       --memlimit-mt-decompress=limit
+              Set a memory usage limit for multi-threaded decompression.  This
+              can  only  affect the number of threads; this will never make xz
+              refuse to decompress a file.  If limit is too low to  allow  any
+              multi-threading,  the  limit  is ignored and xz will continue in
+              single-threaded mode.  Note that if  also  --memlimit-decompress
+              is used, it will always apply to both single-threaded and multi-
+              threaded modes, and so the effective limit  for  multi-threading
+              will  never  be higher than the limit set with --memlimit-decom-
+              press.
+
+              In contrast to the other  memory  usage  limit  options,  --mem-
+              limit-mt-decompress=limit  has  a system-specific default limit.
+              xz --info-memory can be used to see the current value.
+
+              This option and its default  value  exist  because  without  any
+              limit  the  threaded decompressor could end up allocating an in-
+              sane amount of memory with some input  files.   If  the  default
+              limit is too low on your system, feel free to increase the limit
+              but never set it to a value larger than the amount of usable RAM
+              as  with  appropriate  input  files  xz will attempt to use that
+              amount of memory even with a low number of threads.  Running out
+              of  memory  or  swapping  will not improve decompression perfor-
+              mance.
+
+              See --memlimit-compress=limit for possible ways to  specify  the
+              limit.   Setting limit to 0 resets the limit to the default sys-
+              tem-specific value.
+
+       -M limit, --memlimit=limit, --memory=limit
+              This  is  equivalent  to  specifying   --memlimit-compress=limit
+              --memlimit-decompress=limit --memlimit-mt-decompress=limit.
+
+       --no-adjust
+              Display  an  error  and exit if the memory usage limit cannot be
+              met without adjusting settings that affect the  compressed  out-
+              put.   That is, this prevents xz from switching the encoder from
+              multi-threaded mode to single-threaded mode  and  from  reducing
+              the  LZMA2  dictionary  size.  Even when this option is used the
+              number of threads may be reduced to meet the memory usage  limit
+              as that won't affect the compressed output.
+
+              Automatic adjusting is always disabled when creating raw streams
+              (--format=raw).
+
+       -T threads, --threads=threads
+              Specify the number of worker threads to use.  Setting threads to
+              a special value 0 makes xz use up to as many threads as the pro-
+              cessor(s) on the system support.  The actual number  of  threads
+              can  be  fewer  than threads if the input file is not big enough
+              for threading with the given settings or if using  more  threads
+              would exceed the memory usage limit.
+
+              The  single-threaded and multi-threaded compressors produce dif-
+              ferent output.  Single-threaded compressor will give the  small-
+              est  file  size but only the output from the multi-threaded com-
+              pressor can be decompressed  using  multiple  threads.   Setting
+              threads to 1 will use the single-threaded mode.  Setting threads
+              to any other value, including 0,  will  use  the  multi-threaded
+              compressor even if the system supports only one hardware thread.
+              (xz 5.2.x used single-threaded mode in this situation.)
+
+              To use multi-threaded mode with only one thread, set threads  to
+              +1.   The  +  prefix  has no effect with values other than 1.  A
+              memory usage limit can still make xz switch  to  single-threaded
+              mode  unless  --no-adjust is used.  Support for the + prefix was
+              added in xz 5.4.0.
+
+              If an automatic number of threads has been requested and no mem-
+              ory  usage  limit has been specified, then a system-specific de-
+              fault soft limit will be used to possibly limit  the  number  of
+              threads.   It is a soft limit in sense that it is ignored if the
+              number of threads becomes one, thus a soft limit will never stop
+              xz  from  compressing or decompressing.  This default soft limit
+              will not make xz switch  from  multi-threaded  mode  to  single-
+              threaded   mode.    The  active  limits  can  be  seen  with  xz
+              --info-memory.
+
+              Currently the only threading method is to split the  input  into
+              blocks and compress them independently from each other.  The de-
+              fault block size depends on the compression  level  and  can  be
+              overridden with the --block-size=size option.
+
+              Threaded decompression only works on files that contain multiple
+              blocks with size information in block headers.  All large enough
+              files compressed in multi-threaded mode meet this condition, but
+              files  compressed  in  single-threaded  mode   don't   even   if
+              --block-size=size has been used.
+
+   Custom compressor filter chains
+       A custom filter chain allows specifying the compression settings in de-
+       tail instead of relying on the  settings  associated  to  the  presets.
+       When  a custom filter chain is specified, preset options (-0 ... -9 and
+       --extreme) earlier on the command line are forgotten.  If a preset  op-
+       tion  is  specified  after one or more custom filter chain options, the
+       new preset takes effect and the custom filter chain  options  specified
+       earlier are forgotten.
+
+       A  filter chain is comparable to piping on the command line.  When com-
+       pressing, the uncompressed input goes to the first filter, whose output
+       goes  to  the next filter (if any).  The output of the last filter gets
+       written to the compressed file.  The maximum number of filters  in  the
+       chain  is  four,  but typically a filter chain has only one or two fil-
+       ters.
+
+       Many filters have limitations on where they can be in the filter chain:
+       some  filters  can work only as the last filter in the chain, some only
+       as a non-last filter, and some work in any position in the chain.   De-
+       pending on the filter, this limitation is either inherent to the filter
+       design or exists to prevent security issues.
+
+       A custom filter chain is specified by using one or more filter  options
+       in  the  order they are wanted in the filter chain.  That is, the order
+       of filter options is significant!  When decoding  raw  streams  (--for-
+       mat=raw),  the  filter  chain  is specified in the same order as it was
+       specified when compressing.
+
+       Filters take filter-specific options as a comma-separated list.   Extra
+       commas  in  options  are ignored.  Every option has a default value, so
+       you need to specify only those you want to change.
+
+       To see the whole filter chain and options, use xz  -vv  (that  is,  use
+       --verbose twice).  This works also for viewing the filter chain options
+       used by presets.
+
+       --lzma1[=options]
+       --lzma2[=options]
+              Add LZMA1 or LZMA2 filter to the filter  chain.   These  filters
+              can be used only as the last filter in the chain.
+
+              LZMA1  is  a legacy filter, which is supported almost solely due
+              to the legacy .lzma file  format,  which  supports  only  LZMA1.
+              LZMA2  is  an updated version of LZMA1 to fix some practical is-
+              sues of LZMA1.  The .xz format uses LZMA2  and  doesn't  support
+              LZMA1  at  all.  Compression speed and ratios of LZMA1 and LZMA2
+              are practically the same.
+
+              LZMA1 and LZMA2 share the same set of options:
+
+              preset=preset
+                     Reset all LZMA1 or LZMA2 options to preset.  Preset  con-
+                     sist  of an integer, which may be followed by single-let-
+                     ter preset modifiers.  The integer can be from  0  to  9,
+                     matching  the  command  line options -0 ... -9.  The only
+                     supported modifier is currently e,  which  matches  --ex-
+                     treme.   If no preset is specified, the default values of
+                     LZMA1 or LZMA2 options are taken from the preset 6.
+
+              dict=size
+                     Dictionary (history buffer) size indicates how many bytes
+                     of  the  recently  processed uncompressed data is kept in
+                     memory.  The algorithm tries to find repeating  byte  se-
+                     quences  (matches)  in the uncompressed data, and replace
+                     them with references to the data currently in the dictio-
+                     nary.   The  bigger  the  dictionary,  the  higher is the
+                     chance to find a match.  Thus, increasing dictionary size
+                     usually improves compression ratio, but a dictionary big-
+                     ger than the uncompressed file is waste of memory.
+
+                     Typical dictionary size is from 64 KiB  to  64 MiB.   The
+                     minimum  is  4 KiB.   The maximum for compression is cur-
+                     rently 1.5 GiB (1536 MiB).  The decompressor already sup-
+                     ports  dictionaries up to one byte less than 4 GiB, which
+                     is the maximum for the LZMA1 and LZMA2 stream formats.
+
+                     Dictionary size and match finder (mf) together  determine
+                     the memory usage of the LZMA1 or LZMA2 encoder.  The same
+                     (or bigger) dictionary size is required for decompressing
+                     that  was used when compressing, thus the memory usage of
+                     the decoder is determined by  the  dictionary  size  used
+                     when  compressing.   The .xz headers store the dictionary
+                     size either as 2^n or 2^n + 2^(n-1), so these  sizes  are
+                     somewhat preferred for compression.  Other sizes will get
+                     rounded up when stored in the .xz headers.
+
+              lc=lc  Specify the number of literal context bits.  The  minimum
+                     is  0  and  the maximum is 4; the default is 3.  In addi-
+                     tion, the sum of lc and lp must not exceed 4.
+
+                     All bytes that cannot be encoded as matches  are  encoded
+                     as  literals.   That  is, literals are simply 8-bit bytes
+                     that are encoded one at a time.
+
+                     The literal coding makes an assumption that  the  highest
+                     lc  bits of the previous uncompressed byte correlate with
+                     the next byte.  For example, in typical English text,  an
+                     upper-case  letter is often followed by a lower-case let-
+                     ter, and a lower-case letter is usually followed  by  an-
+                     other  lower-case letter.  In the US-ASCII character set,
+                     the highest three bits are 010 for upper-case letters and
+                     011  for  lower-case letters.  When lc is at least 3, the
+                     literal coding can take advantage of this property in the
+                     uncompressed data.
+
+                     The default value (3) is usually good.  If you want maxi-
+                     mum compression, test lc=4.  Sometimes it helps a little,
+                     and sometimes it makes compression worse.  If it makes it
+                     worse, test lc=2 too.
+
+              lp=lp  Specify the number of literal position bits.  The minimum
+                     is 0 and the maximum is 4; the default is 0.
+
+                     Lp  affects  what  kind  of alignment in the uncompressed
+                     data is assumed when encoding literals.  See pb below for
+                     more information about alignment.
+
+              pb=pb  Specify  the  number  of position bits.  The minimum is 0
+                     and the maximum is 4; the default is 2.
+
+                     Pb affects what kind of  alignment  in  the  uncompressed
+                     data  is assumed in general.  The default means four-byte
+                     alignment (2^pb=2^2=4), which is often a good choice when
+                     there's no better guess.
+
+                     When  the  alignment is known, setting pb accordingly may
+                     reduce the file size a little.  For  example,  with  text
+                     files  having  one-byte  alignment (US-ASCII, ISO-8859-*,
+                     UTF-8), setting pb=0 can  improve  compression  slightly.
+                     For UTF-16 text, pb=1 is a good choice.  If the alignment
+                     is an odd number like 3 bytes, pb=0  might  be  the  best
+                     choice.
+
+                     Even though the assumed alignment can be adjusted with pb
+                     and lp, LZMA1 and  LZMA2  still  slightly  favor  16-byte
+                     alignment.   It  might  be worth taking into account when
+                     designing file formats that are likely to be  often  com-
+                     pressed with LZMA1 or LZMA2.
+
+              mf=mf  Match  finder has a major effect on encoder speed, memory
+                     usage, and compression ratio.  Usually Hash  Chain  match
+                     finders  are  faster than Binary Tree match finders.  The
+                     default depends on the preset: 0 uses hc3, 1-3  use  hc4,
+                     and the rest use bt4.
+
+                     The  following  match  finders are supported.  The memory
+                     usage formulas below are rough approximations, which  are
+                     closest to the reality when dict is a power of two.
+
+                     hc3    Hash Chain with 2- and 3-byte hashing
+                            Minimum value for nice: 3
+                            Memory usage:
+                            dict * 7.5 (if dict <= 16 MiB);
+                            dict * 5.5 + 64 MiB (if dict > 16 MiB)
+
+                     hc4    Hash Chain with 2-, 3-, and 4-byte hashing

+                            Memory usage:

+
+              mode=mode
+                     Compression mode specifies the method to analyze the data
+                     produced by the match finder.  Supported modes  are  fast
+                     and normal.  The default is fast for presets 0-3 and nor-
+                     mal for presets 4-9.
+
+                     Usually fast is used with Hash Chain  match  finders  and
+                     normal with Binary Tree match finders.  This is also what
+                     the presets do.
+
+              nice=nice
+                     Specify what is considered to be  a  nice  length  for  a
+                     match.  Once a match of at least nice bytes is found, the
+                     algorithm stops looking for possibly better matches.
+
+                     Nice can be 2-273 bytes.  Higher values tend to give bet-
+                     ter  compression  ratio at the expense of speed.  The de-
+                     fault depends on the preset.
+
+              depth=depth
+                     Specify the maximum search depth  in  the  match  finder.
+                     The  default  is  the special value of 0, which makes the
+                     compressor determine a reasonable depth from mf and nice.
+
+                     Reasonable depth for Hash Chains is 4-100 and 16-1000 for
+                     Binary  Trees.  Using very high values for depth can make
+                     the encoder extremely slow with some files.   Avoid  set-
+                     ting  the  depth over 1000 unless you are prepared to in-
+                     terrupt the compression in case  it  is  taking  far  too
+                     long.
+
+              When  decoding  raw streams (--format=raw), LZMA2 needs only the
+              dictionary size.  LZMA1 needs also lc, lp, and pb.

+              Add a branch/call/jump (BCJ) filter to the filter chain.   These
+              filters  can  be  used  only  as a non-last filter in the filter
+              chain.
+
+              A BCJ filter converts relative addresses in the machine code  to
+              their  absolute  counterparts.   This doesn't change the size of
+              the data but it increases redundancy, which can  help  LZMA2  to
+              produce 0-15 % smaller .xz file.  The BCJ filters are always re-
+              versible, so using a BCJ filter for wrong type of  data  doesn't
+              cause  any data loss, although it may make the compression ratio
+              slightly worse.  The BCJ filters are very fast and  use  an  in-
+              significant amount of memory.
+
+              These BCJ filters have known problems related to the compression
+              ratio:
+
+              o  Some types of files containing executable code (for  example,
+                 object  files,  static  libraries,  and Linux kernel modules)
+                 have the addresses in the  instructions  filled  with  filler
+                 values.   These BCJ filters will still do the address conver-
+                 sion, which will make the compression worse with these files.
+
+              o  If a BCJ filter is applied on an archive, it is possible that
+                 it  makes  the  compression  ratio worse than not using a BCJ
+                 filter.  For example, if there are similar or even  identical
+                 executables  then  filtering  will likely make the files less
+                 similar and thus compression is worse.  The contents of  non-
+                 executable  files  in  the  same  archive can matter too.  In
+                 practice one has to try with and without a BCJ filter to  see
+                 which is better in each situation.
+
+              Different  instruction  sets  have different alignment: the exe-
+              cutable file must be aligned to a multiple of this value in  the
+              input data to make the filter work.
+
+                     Filter      Alignment   Notes
+                     x86             1       32-bit or 64-bit x86
+                     ARM             4
+                     ARM-Thumb       2

+                     SPARC           4
+
+              Since  the  BCJ-filtered  data is usually compressed with LZMA2,
+              the compression ratio may be improved slightly if the LZMA2  op-
+              tions are set to match the alignment of the selected BCJ filter.
+              For example, with the IA-64 filter, it's good  to  set  pb=4  or
+              even  pb=4,lp=4,lc=0  with LZMA2 (2^4=16).  The x86 filter is an
+              exception; it's usually good to stick to LZMA2's  default  four-
+              byte alignment when compressing x86 executables.
+
+              All BCJ filters support the same options:
+
+              start=offset
+                     Specify the start offset that is used when converting be-
+                     tween relative and absolute addresses.  The  offset  must
+                     be a multiple of the alignment of the filter (see the ta-
+                     ble above).  The default is zero.  In practice,  the  de-
+                     fault is good; specifying a custom offset is almost never
+                     useful.
+
+       --delta[=options]
+              Add the Delta filter to the filter chain.  The Delta filter  can
+              be only used as a non-last filter in the filter chain.
+
+              Currently  only simple byte-wise delta calculation is supported.
+              It can be useful when  compressing,  for  example,  uncompressed
+              bitmap  images or uncompressed PCM audio.  However, special pur-
+              pose algorithms may give significantly better results than Delta
+              +  LZMA2.   This is true especially with audio, which compresses
+              faster and better, for example, with flac(1).
+
+              Supported options:
+
+              dist=distance
+                     Specify the distance of the delta calculation  in  bytes.
+                     distance must be 1-256.  The default is 1.
+
+                     For example, with dist=2 and eight-byte input A1 B1 A2 B3
+                     A3 B5 A4 B7, the output will be A1 B1 01 02 01 02 01 02.
+
+   Other options
+       -q, --quiet
+              Suppress warnings and notices.  Specify this twice  to  suppress
+              errors too.  This option has no effect on the exit status.  That
+              is, even if a warning was suppressed, the exit status  to  indi-
+              cate a warning is still used.
+
+       -v, --verbose
+              Be  verbose.   If  standard error is connected to a terminal, xz
+              will display a progress indicator.  Specifying  --verbose  twice
+              will give even more verbose output.
+
+              The progress indicator shows the following information:
+
+              o  Completion  percentage is shown if the size of the input file
+                 is known.  That is, the percentage cannot be shown in pipes.
+
+              o  Amount of compressed data produced (compressing) or  consumed
+                 (decompressing).
+
+              o  Amount  of  uncompressed  data consumed (compressing) or pro-
+                 duced (decompressing).
+
+              o  Compression ratio, which is calculated by dividing the amount
+                 of  compressed  data processed so far by the amount of uncom-
+                 pressed data processed so far.
+
+              o  Compression or decompression speed.  This is measured as  the
+                 amount  of  uncompressed  data consumed (compression) or pro-
+                 duced (decompression) per second.  It is shown  after  a  few
+                 seconds have passed since xz started processing the file.
+
+              o  Elapsed time in the format M:SS or H:MM:SS.
+
+              o  Estimated  remaining  time is shown only when the size of the
+                 input file is known and a  couple  of  seconds  have  already
+                 passed  since  xz  started  processing the file.  The time is
+                 shown in a less precise format which never  has  any  colons,
+                 for example, 2 min 30 s.
+
+              When  standard  error  is not a terminal, --verbose will make xz
+              print the filename, compressed size, uncompressed size, compres-
+              sion  ratio,  and  possibly also the speed and elapsed time on a
+              single line to standard error after compressing or decompressing
+              the file.  The speed and elapsed time are included only when the
+              operation took at least a few seconds.  If the operation  didn't
+              finish,  for example, due to user interruption, also the comple-
+              tion percentage is printed if the size  of  the  input  file  is
+              known.
+
+       -Q, --no-warn
+              Don't set the exit status to 2 even if a condition worth a warn-
+              ing was detected.  This  option  doesn't  affect  the  verbosity
+              level,  thus  both  --quiet and --no-warn have to be used to not
+              display warnings and to not alter the exit status.
+
+       --robot
+              Print messages in a machine-parsable format.  This  is  intended
+              to  ease  writing  frontends  that want to use xz instead of li-
+              blzma, which may be the case with various scripts.   The  output
+              with  this  option  enabled  is meant to be stable across xz re-
+              leases.  See the section ROBOT MODE for details.
+
+       --info-memory
+              Display, in human-readable  format,  how  much  physical  memory
+              (RAM)  and  how  many processor threads xz thinks the system has
+              and the memory usage limits for compression  and  decompression,
+              and exit successfully.
+
+       -h, --help
+              Display  a  help  message  describing the most commonly used op-
+              tions, and exit successfully.
+
+       -H, --long-help
+              Display a help message describing all features of xz,  and  exit
+              successfully
+
+       -V, --version
+              Display  the  version number of xz and liblzma in human readable
+              format.  To get machine-parsable output, specify --robot  before
+              --version.
+
+ROBOT MODE
+       The robot mode is activated with the --robot option.  It makes the out-
+       put of xz easier to parse by other programs.  Currently --robot is sup-
+       ported  only  together  with  --version, --info-memory, and --list.  It
+       will be supported for compression and decompression in the future.
+
+   Version
+       xz --robot --version prints the version number of xz and liblzma in the
+       following format:
+
+       XZ_VERSION=XYYYZZZS
+       LIBLZMA_VERSION=XYYYZZZS
+
+       X      Major version.
+
+       YYY    Minor  version.  Even numbers are stable.  Odd numbers are alpha
+              or beta versions.
+
+       ZZZ    Patch level for stable releases or just a counter  for  develop-
+              ment releases.
+
+       S      Stability.  0 is alpha, 1 is beta, and 2 is stable.  S should be
+              always 2 when YYY is even.
+
+       XYYYZZZS are the same on both lines if xz and liblzma are from the same
+       XZ Utils release.
+
+       Examples: 4.999.9beta is 49990091 and 5.0.0 is 50000002.
+
+   Memory limit information
+       xz  --robot  --info-memory prints a single line with multiple tab-sepa-
+       rated columns:
+
+       1.  Total amount of physical memory (RAM) in bytes.
+
+       2.  Memory usage limit for compression in bytes  (--memlimit-compress).
+           A  special  value of 0 indicates the default setting which for sin-
+           gle-threaded mode is the same as no limit.
+
+       3.  Memory usage limit for decompression  in  bytes  (--memlimit-decom-
+           press).   A  special value of 0 indicates the default setting which
+           for single-threaded mode is the same as no limit.
+
+       4.  Since xz 5.3.4alpha: Memory usage for multi-threaded  decompression
+           in  bytes (--memlimit-mt-decompress).  This is never zero because a
+           system-specific default value shown in the column 5 is used  if  no
+           limit  has  been  specified explicitly.  This is also never greater
+           than the value in the column 3 even if  a  larger  value  has  been
+           specified with --memlimit-mt-decompress.
+
+       5.  Since  xz  5.3.4alpha: A system-specific default memory usage limit
+           that is used to limit the number of threads when  compressing  with
+           an  automatic  number  of threads (--threads=0) and no memory usage
+           limit has been specified (--memlimit-compress).  This is also  used
+           as the default value for --memlimit-mt-decompress.
+
+       6.  Since xz 5.3.4alpha: Number of available processor threads.
+
+       In  the  future,  the  output of xz --robot --info-memory may have more
+       columns, but never more than a single line.
+
+   List mode
+       xz --robot --list uses tab-separated output.  The first column of every
+       line  has  a string that indicates the type of the information found on
+       that line:
+
+       name   This is always the first line when starting to list a file.  The
+              second column on the line is the filename.
+
+       file   This line contains overall information about the .xz file.  This
+              line is always printed after the name line.
+
+       stream This line type is used only when --verbose was specified.  There
+              are as many stream lines as there are streams in the .xz file.
+
+       block  This line type is used only when --verbose was specified.  There
+              are as many block lines as there are blocks  in  the  .xz  file.
+              The  block lines are shown after all the stream lines; different
+              line types are not interleaved.
+
+       summary
+              This line type is used only when --verbose was specified  twice.
+              This line is printed after all block lines.  Like the file line,
+              the summary line contains  overall  information  about  the  .xz
+              file.
+
+       totals This  line  is always the very last line of the list output.  It
+              shows the total counts and sizes.
+
+       The columns of the file lines:
+              2.  Number of streams in the file
+              3.  Total number of blocks in the stream(s)
+              4.  Compressed size of the file
+              5.  Uncompressed size of the file
+              6.  Compression ratio, for example, 0.123.   If  ratio  is  over
+                  9.999,  three  dashes (---) are displayed instead of the ra-
+                  tio.
+              7.  Comma-separated list of integrity check names.  The  follow-
+                  ing strings are used for the known check types: None, CRC32,
+                  CRC64, and SHA-256.  For unknown check types,  Unknown-N  is
+                  used,  where  N  is the Check ID as a decimal number (one or
+                  two digits).
+              8.  Total size of stream padding in the file
+
+       The columns of the stream lines:
+              2.  Stream number (the first stream is 1)
+              3.  Number of blocks in the stream
+              4.  Compressed start offset
+              5.  Uncompressed start offset
+              6.  Compressed size (does not include stream padding)
+              7.  Uncompressed size

+
+       If  --verbose  was  specified twice, additional columns are included on
+       the block lines.  These are not displayed with a single --verbose,  be-
+       cause  getting  this  information  requires  many seeks and can thus be

+                  lier columns the same as on file lines.
+
+       If --verbose was specified twice, additional columns  are  included  on

+              10. Maximum  amount  of memory (in bytes) required to decompress
+                  the files with this xz version
+              11. yes or no indicating if all block  headers  have  both  com-

+              Since xz 5.1.2alpha:
+              12. Minimum xz version required to decompress the file
+
+       Future  versions may add new line types and new columns can be added to
+       the existing line types, but the existing columns won't be changed.
+
+EXIT STATUS
+       0      All is good.
+
+       1      An error occurred.
+
+       2      Something worth a warning occurred, but  no  actual  errors  oc-
+              curred.
+
+       Notices (not warnings or errors) printed on standard error don't affect
+       the exit status.
+
+ENVIRONMENT
+       xz parses space-separated lists of options from the  environment  vari-
+       ables XZ_DEFAULTS and XZ_OPT, in this order, before parsing the options
+       from the command line.  Note that only options are parsed from the  en-
+       vironment  variables; all non-options are silently ignored.  Parsing is
+       done with getopt_long(3) which is used also for the command line  argu-
+       ments.
+
+       XZ_DEFAULTS
+              User-specific or system-wide default options.  Typically this is
+              set in a shell initialization script to enable xz's memory usage
+              limiter  by default.  Excluding shell initialization scripts and
+              similar special cases, scripts must never set  or  unset  XZ_DE-
+              FAULTS.
+
+       XZ_OPT This is for passing options to xz when it is not possible to set
+              the options directly on the xz command line.  This is  the  case
+              when xz is run by a script or tool, for example, GNU tar(1):
+
+                     XZ_OPT=-2v tar caf foo.tar.xz foo
+
+              Scripts  may use XZ_OPT, for example, to set script-specific de-
+              fault compression options.  It is  still  recommended  to  allow
+              users to override XZ_OPT if that is reasonable.  For example, in
+              sh(1) scripts one may use something like this:
+
+                     XZ_OPT=${XZ_OPT-"-7e"}
+                     export XZ_OPT
+
+LZMA UTILS COMPATIBILITY
+       The command line syntax of xz is practically a superset  of  lzma,  un-
+       lzma,  and lzcat as found from LZMA Utils 4.32.x.  In most cases, it is
+       possible to replace LZMA Utils with XZ Utils without breaking  existing
+       scripts.   There are some incompatibilities though, which may sometimes
+       cause problems.
+
+   Compression preset levels
+       The numbering of the compression level presets is not identical  in  xz
+       and  LZMA Utils.  The most important difference is how dictionary sizes
+       are mapped to different presets.  Dictionary size is roughly  equal  to
+       the decompressor memory usage.
+
+              Level     xz      LZMA Utils
+               -0     256 KiB      N/A
+               -1       1 MiB     64 KiB
+               -2       2 MiB      1 MiB
+               -3       4 MiB    512 KiB
+               -4       4 MiB      1 MiB
+               -5       8 MiB      2 MiB
+               -6       8 MiB      4 MiB
+               -7      16 MiB      8 MiB
+               -8      32 MiB     16 MiB
+               -9      64 MiB     32 MiB
+
+       The dictionary size differences affect the compressor memory usage too,
+       but there are some other differences between LZMA Utils and  XZ  Utils,
+       which make the difference even bigger:
+
+              Level     xz      LZMA Utils 4.32.x
+               -0       3 MiB          N/A
+               -1       9 MiB          2 MiB
+               -2      17 MiB         12 MiB
+               -3      32 MiB         12 MiB
+               -4      48 MiB         16 MiB
+               -5      94 MiB         26 MiB
+               -6      94 MiB         45 MiB
+               -7     186 MiB         83 MiB
+               -8     370 MiB        159 MiB
+               -9     674 MiB        311 MiB
+
+       The  default  preset  level in LZMA Utils is -7 while in XZ Utils it is
+       -6, so both use an 8 MiB dictionary by default.
+
+   Streamed vs. non-streamed .lzma files
+       The uncompressed size of the file can be stored in  the  .lzma  header.
+       LZMA  Utils  does that when compressing regular files.  The alternative
+       is to mark that uncompressed size is  unknown  and  use  end-of-payload
+       marker to indicate where the decompressor should stop.  LZMA Utils uses
+       this method when uncompressed size isn't known, which is the case,  for
+       example, in pipes.
+
+       xz  supports  decompressing  .lzma files with or without end-of-payload
+       marker, but all .lzma files  created  by  xz  will  use  end-of-payload
+       marker  and  have  uncompressed  size  marked  as  unknown in the .lzma
+       header.  This may be a problem in some uncommon situations.  For  exam-
+       ple,  a  .lzma  decompressor in an embedded device might work only with
+       files that have known uncompressed size.  If you hit this problem,  you
+       need to use LZMA Utils or LZMA SDK to create .lzma files with known un-
+       compressed size.
+
+   Unsupported .lzma files
+       The .lzma format allows lc values up to 8, and lp values up to 4.  LZMA
+       Utils can decompress files with any lc and lp, but always creates files
+       with lc=3 and lp=0.  Creating files with other lc and  lp  is  possible
+       with xz and with LZMA SDK.
+
+       The implementation of the LZMA1 filter in liblzma requires that the sum
+       of lc and lp must not exceed 4.  Thus, .lzma files, which  exceed  this
+       limitation, cannot be decompressed with xz.
+
+       LZMA Utils creates only .lzma files which have a dictionary size of 2^n
+       (a power of 2) but accepts files with any dictionary size.  liblzma ac-
+       cepts  only  .lzma  files  which have a dictionary size of 2^n or 2^n +
+       2^(n-1).  This is to decrease  false  positives  when  detecting  .lzma
+       files.
+
+       These limitations shouldn't be a problem in practice, since practically
+       all .lzma files have been compressed with settings  that  liblzma  will
+       accept.
+
+   Trailing garbage
+       When  decompressing,  LZMA  Utils  silently ignore everything after the
+       first .lzma stream.  In most situations, this  is  a  bug.   This  also
+       means  that  LZMA  Utils don't support decompressing concatenated .lzma
+       files.
+
+       If there is data left after the first .lzma stream,  xz  considers  the
+       file to be corrupt unless --single-stream was used.  This may break ob-
+       scure scripts which have assumed that trailing garbage is ignored.
+
+NOTES
+   Compressed output may vary
+       The exact compressed output produced from the same  uncompressed  input
+       file may vary between XZ Utils versions even if compression options are
+       identical.  This is because the encoder can be improved (faster or bet-
+       ter  compression)  without  affecting  the file format.  The output can
+       vary even between different builds of the same  XZ  Utils  version,  if
+       different build options are used.
+
+       The above means that once --rsyncable has been implemented, the result-
+       ing files won't necessarily be rsyncable unless both old and new  files
+       have  been  compressed  with  the same xz version.  This problem can be
+       fixed if a part of the encoder implementation is frozen to keep rsynca-
+       ble output stable across xz versions.
+
+   Embedded .xz decompressors
+       Embedded .xz decompressor implementations like XZ Embedded don't neces-
+       sarily support files created with integrity check types other than none
+       and   crc32.    Since  the  default  is  --check=crc64,  you  must  use
+       --check=none or --check=crc32 when creating files for embedded systems.
+
+       Outside embedded systems, all .xz format decompressors support all  the
+       check  types, or at least are able to decompress the file without veri-
+       fying the integrity check if the particular check is not supported.
+
+       XZ Embedded supports BCJ filters, but only with the default start  off-
+       set.
+
+EXAMPLES
+   Basics
+       Compress  the  file foo into foo.xz using the default compression level
+       (-6), and remove foo if compression is successful:
+
+              xz foo
+
+       Decompress bar.xz into bar and don't remove bar.xz even  if  decompres-
+       sion is successful:
+
+              xz -dk bar.xz
+
+       Create  baz.tar.xz  with the preset -4e (-4 --extreme), which is slower
+       than the default -6, but needs less memory for compression  and  decom-
+       pression (48 MiB and 5 MiB, respectively):
+
+              tar cf - baz | xz -4e > baz.tar.xz
+
+       A mix of compressed and uncompressed files can be decompressed to stan-
+       dard output with a single command:
+
+              xz -dcf a.txt b.txt.xz c.txt d.txt.lzma > abcd.txt
+
+   Parallel compression of many files
+       On GNU and *BSD, find(1) and xargs(1) can be used to  parallelize  com-
+       pression of many files:
+
+              find . -type f \! -name '*.xz' -print0 \
+                  | xargs -0r -P4 -n16 xz -T1
+
+       The  -P  option  to  xargs(1) sets the number of parallel xz processes.
+       The best value for the -n option depends on how many files there are to
+       be  compressed.   If there are only a couple of files, the value should
+       probably be 1; with tens of thousands of files, 100 or even more may be
+       appropriate  to  reduce  the  number of xz processes that xargs(1) will
+       eventually create.
+
+       The option -T1 for xz is there to force it to single-threaded mode, be-
+       cause xargs(1) is used to control the amount of parallelization.
+
+   Robot mode
+       Calculate  how  many  bytes  have been saved in total after compressing
+       multiple files:
+
+              xz --robot --list *.xz | awk '/^totals/{print $5-$4}'
+
+       A script may want to know that it is using new enough xz.  The  follow-
+       ing  sh(1)  script  checks that the version number of the xz tool is at
+       least 5.0.0.  This method is compatible with old beta  versions,  which
+       didn't support the --robot option:
+
+              if ! eval "$(xz --robot --version 2> /dev/null)" ||
+                      [ "$XZ_VERSION" -lt 50000002 ]; then
+                  echo "Your xz is too old."
+              fi
+              unset XZ_VERSION LIBLZMA_VERSION
+
+       Set a memory usage limit for decompression using XZ_OPT, but if a limit
+       has already been set, don't increase it:
+
+              NEWLIM=$((123 << 20))  # 123 MiB
+              OLDLIM=$(xz --robot --info-memory | cut -f3)
+              if [ $OLDLIM -eq 0 -o $OLDLIM -gt $NEWLIM ]; then
+                  XZ_OPT="$XZ_OPT --memlimit-decompress=$NEWLIM"
+                  export XZ_OPT
+              fi
+
+   Custom compressor filter chains
+       The simplest use for custom filter chains is customizing a  LZMA2  pre-
+       set.   This  can  be useful, because the presets cover only a subset of
+       the potentially useful combinations of compression settings.
+
+       The CompCPU columns of the tables from the descriptions of the  options
+       -0  ...  -9  and  --extreme  are useful when customizing LZMA2 presets.
+       Here are the relevant parts collected from those two tables:
+
+              Preset   CompCPU
+               -0         0
+               -1         1
+               -2         2
+               -3         3
+               -4         4
+               -5         5
+               -6         6
+               -5e        7
+               -6e        8
+
+       If you know that a file requires somewhat big dictionary (for  example,
+       32 MiB)  to  compress well, but you want to compress it quicker than xz
+       -8 would do, a preset with a low CompCPU value (for example, 1) can  be
+       modified to use a bigger dictionary:
+
+              xz --lzma2=preset=1,dict=32MiB foo.tar
+
+       With  certain  files,  the above command may be faster than xz -6 while
+       compressing significantly better.  However, it must be emphasized  that
+       only some files benefit from a big dictionary while keeping the CompCPU
+       value low.  The most obvious situation, where a big dictionary can help
+       a  lot,  is  an archive containing very similar files of at least a few
+       megabytes each.  The dictionary size has  to  be  significantly  bigger
+       than  any  individual file to allow LZMA2 to take full advantage of the
+       similarities between consecutive files.
+
+       If very high compressor and decompressor memory usage is fine, and  the
+       file  being compressed is at least several hundred megabytes, it may be
+       useful to use an even bigger dictionary than the  64  MiB  that  xz  -9
+       would use:
+
+              xz -vv --lzma2=dict=192MiB big_foo.tar
+
+       Using -vv (--verbose --verbose) like in the above example can be useful
+       to see the memory requirements of the compressor and decompressor.  Re-
+       member that using a dictionary bigger than the size of the uncompressed
+       file is waste of memory, so the above command isn't  useful  for  small
+       files.
+
+       Sometimes  the  compression  time  doesn't matter, but the decompressor
+       memory usage has to be kept low, for example, to make  it  possible  to
+       decompress  the file on an embedded system.  The following command uses
+       -6e (-6 --extreme) as a base and sets the dictionary  to  only  64 KiB.
+       The  resulting  file  can  be decompressed with XZ Embedded (that's why
+       there is --check=crc32) using about 100 KiB of memory.
+
+              xz --check=crc32 --lzma2=preset=6e,dict=64KiB foo
+
+       If you want to squeeze out as many bytes  as  possible,  adjusting  the
+       number  of  literal  context bits (lc) and number of position bits (pb)
+       can sometimes help.  Adjusting the number of literal position bits (lp)
+       might help too, but usually lc and pb are more important.  For example,
+       a source code archive contains mostly US-ASCII text, so something  like
+       the following might give slightly (like 0.1 %) smaller file than xz -6e
+       (try also without lc=4):
+
+              xz --lzma2=preset=6e,pb=0,lc=4 source_code.tar
+
+       Using another filter together with LZMA2 can improve  compression  with
+       certain file types.  For example, to compress a x86-32 or x86-64 shared
+       library using the x86 BCJ filter:
+
+              xz --x86 --lzma2 libfoo.so
+
+       Note that the order of the filter options is significant.  If --x86  is
+       specified after --lzma2, xz will give an error, because there cannot be
+       any filter after LZMA2, and also because the x86 BCJ filter  cannot  be
+       used as the last filter in the chain.
+
+       The  Delta filter together with LZMA2 can give good results with bitmap
+       images.  It should usually beat PNG, which has a few more advanced fil-
+       ters than simple delta but uses Deflate for the actual compression.
+
+       The  image  has to be saved in uncompressed format, for example, as un-
+       compressed TIFF.  The distance parameter of the Delta filter is set  to
+       match  the number of bytes per pixel in the image.  For example, 24-bit
+       RGB bitmap needs dist=3, and it is also good to pass pb=0 to  LZMA2  to
+       accommodate the three-byte alignment:
+
+              xz --delta=dist=3 --lzma2=pb=0 foo.tiff
+
+       If  multiple  images  have been put into a single archive (for example,
+       .tar), the Delta filter will work on that too as  long  as  all  images
+       have the same number of bytes per pixel.

+XZDEC(1)                           XZ Utils                           XZDEC(1)
+
+
+
+NAME
+       xzdec, lzmadec - Small .xz and .lzma decompressors
+
+SYNOPSIS
+       xzdec [option...]  [file...]
+       lzmadec [option...]  [file...]
+
+DESCRIPTION
+       xzdec is a liblzma-based decompression-only tool for .xz (and only .xz)
+       files.  xzdec is intended to work as a drop-in replacement for xz(1) in
+       the  most  common  situations where a script has been written to use xz
+       --decompress --stdout (and possibly a few other commonly used  options)
+       to decompress .xz files.  lzmadec is identical to xzdec except that lz-
+       madec supports .lzma files instead of .xz files.
+
+       To reduce the size of the  executable,  xzdec  doesn't  support  multi-
+       threading  or  localization,  and doesn't read options from XZ_DEFAULTS
+       and XZ_OPT environment variables.  xzdec doesn't support displaying in-
+       termediate progress information: sending SIGINFO to xzdec does nothing,
+       but sending  SIGUSR1  terminates  the  process  instead  of  displaying
+       progress information.
+
+OPTIONS
+       -d, --decompress, --uncompress
+              Ignored for xz(1) compatibility.  xzdec supports only decompres-
+              sion.
+
+       -k, --keep
+              Ignored for xz(1) compatibility.  xzdec never creates or removes
+              any files.
+
+       -c, --stdout, --to-stdout
+              Ignored for xz(1) compatibility.  xzdec always writes the decom-
+              pressed data to standard output.
+
+       -q, --quiet
+              Specifying this once does nothing since xzdec never displays any
+              warnings or notices.  Specify this twice to suppress errors.
+
+       -Q, --no-warn
+              Ignored for xz(1) compatibility.  xzdec never uses the exit sta-
+              tus 2.
+
+       -h, --help
+              Display a help message and exit successfully.
+
+       -V, --version
+              Display the version number of xzdec and liblzma.
+
+EXIT STATUS
+       0      All was good.
+
+       1      An error occurred.
+
+       xzdec doesn't have any warning messages like xz(1) has, thus  the  exit
+       status 2 is not used by xzdec.
+
+NOTES
+       Use  xz(1)  instead of xzdec or lzmadec for normal everyday use.  xzdec
+       or lzmadec are meant only for situations where it is important to  have
+       a smaller decompressor than the full-featured xz(1).
+
+       xzdec  and  lzmadec are not really that small.  The size can be reduced
+       further by dropping features from liblzma at  compile  time,  but  that
+       shouldn't  usually  be done for executables distributed in typical non-
+       embedded operating system distributions.  If you need a truly small .xz
+       decompressor, consider using XZ Embedded.

+NAME
+       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files
+
+SYNOPSIS

+       lzcmp [cmp_options] file1 [file2]
+       lzdiff [diff_options] file1 [file2]
+
+DESCRIPTION
+       xzcmp  and  xzdiff  invoke  cmp(1)  or diff(1) on files compressed with
+       xz(1), lzma(1), gzip(1), bzip2(1), lzop(1), or  zstd(1).   All  options
+       specified  are  passed directly to cmp(1) or diff(1).  If only one file
+       is specified, then the files compared are file1 (which must have a suf-
+       fix  of  a  supported compression format) and file1 from which the com-
+       pression format suffix has been stripped.  If two files are  specified,
+       then  they  are uncompressed if necessary and fed to cmp(1) or diff(1).
+       The exit status from cmp(1) or diff(1) is preserved unless a decompres-
+       sion error occurs; then exit status is 2.
+
+       The names lzcmp and lzdiff are provided for backward compatibility with
+       LZMA Utils.

+
+NAME
+       xzgrep - search compressed files for a regular expression
+
+SYNOPSIS
+       xzgrep [grep_options] [-e] pattern [file...]
+       xzegrep ...
+       xzfgrep ...
+       lzgrep ...
+       lzegrep ...
+       lzfgrep ...
+
+DESCRIPTION
+       xzgrep  invokes  grep(1)  on  files which may be either uncompressed or
+       compressed with xz(1), lzma(1), gzip(1), bzip2(1), lzop(1), or zstd(1).
+       All options specified are passed directly to grep(1).
+
+       If  no file is specified, then standard input is decompressed if neces-
+       sary and fed to grep(1).  When reading from  standard  input,  gzip(1),
+       bzip2(1), lzop(1), and zstd(1) compressed files are not supported.
+
+       If  xzgrep  is invoked as xzegrep or xzfgrep then grep -E or grep -F is
+       used instead of grep(1).  The same applies to  names  lzgrep,  lzegrep,
+       and  lzfgrep,  which  are provided for backward compatibility with LZMA
+       Utils.
+
+EXIT STATUS
+       0      At least one match was found from at  least  one  of  the  input
+              files.  No errors occurred.
+
+       1      No  matches  were  found from any of the input files.  No errors

+XZLESS(1)                          XZ Utils                          XZLESS(1)
+
+
+
+NAME
+       xzless, lzless - view xz or lzma compressed (text) files
+
+SYNOPSIS
+       xzless [file...]
+       lzless [file...]
+
+DESCRIPTION
+       xzless is a filter that displays text from compressed files to a termi-
+       nal.  It works on files compressed with xz(1) or lzma(1).  If no  files
+       are given, xzless reads from standard input.
+
+       xzless  uses  less(1) to present its output.  Unlike xzmore, its choice
+       of pager cannot be altered by setting an  environment  variable.   Com-
+       mands  are  based  on  both  more(1) and vi(1) and allow back and forth
+       movement and searching.  See the less(1) manual for more information.
+
+       The command named lzless is provided for  backward  compatibility  with
+       LZMA Utils.
+
+ENVIRONMENT
+       LESSMETACHARS
+              A list of characters special to the shell.  Set by xzless unless
+              it is already set in the environment.
+
+       LESSOPEN
+              Set to a command line to invoke the xz(1) decompressor for  pre-
+              processing the input files to less(1).

+
+SYNOPSIS
+       xzmore [file...]
+       lzmore [file...]
+
+DESCRIPTION
+       xzmore  is  a  filter which allows examination of xz(1) or lzma(1) com-
+       pressed text files one screenful at a time on a soft-copy terminal.
+
+       To use a pager other than the default more,  set  environment  variable
+       PAGER  to the name of the desired program.  The name lzmore is provided
+       for backward compatibility with LZMA Utils.
+
+       e or q When the prompt --More--(Next file: file) is printed, this  com-
+              mand causes xzmore to exit.
+
+       s      When  the prompt --More--(Next file: file) is printed, this com-
+              mand causes xzmore to skip the next file and continue.
+
+       For list of keyboard commands supported while actually viewing the con-
+       tent of a file, refer to manual of the pager you use, usually more(1).

+0. Preface
+
+        This document describes the .xz file format (filename suffix
+        ".xz", MIME type "application/x-xz"). It is intended that this
+        this format replace the old .lzma format used by LZMA SDK and
+        LZMA Utils.
+
+

+
+1. Conventions
+
+        The key words "MUST", "MUST NOT", "REQUIRED", "SHOULD",
+        "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
+        document are to be interpreted as described in [RFC-2119].
+
+        Indicating a warning means displaying a message, returning
+        appropriate exit status, or doing something else to let the
+        user know that something worth warning occurred. The operation
+        SHOULD still finish if a warning is indicated.
+
+        Indicating an error means displaying a message, returning
+        appropriate exit status, or doing something else to let the
+        user know that something prevented successfully finishing the
+        operation. The operation MUST be aborted once an error has
+        been indicated.
+
+
+1.1. Byte and Its Representation
+
+        In this document, byte is always 8 bits.
+
+        A "null byte" has all bits unset. That is, the value of a null
+        byte is 0x00.
+
+        To represent byte blocks, this document uses notation that
+        is similar to the notation used in [RFC-1952]:
+
+            +-------+
+            |  Foo  |   One byte.
+            +-------+
+
+            +---+---+
+            |  Foo  |   Two bytes; that is, some of the vertical bars
+            +---+---+   can be missing.

+            |  Foo  |   Zero or more bytes.
+            +=======+
+
+        In this document, a boxed byte or a byte sequence declared
+        using this notation is called "a field". The example field
+        above would be called "the Foo field" or plain "Foo".
+
+        If there are many fields, they may be split to multiple lines.
+        This is indicated with an arrow ("--->"):
+
+            +=====+
+            | Foo |
+            +=====+
+
+                 +=====+
+            ---> | Bar |
+                 +=====+
+
+        The above is equivalent to this:
+
+            +=====+=====+
+            | Foo | Bar |
+            +=====+=====+
+
+
+1.2. Multibyte Integers
+
+        Multibyte integers of static length, such as CRC values,
+        are stored in little endian byte order (least significant
+        byte first).
+
+        When smaller values are more likely than bigger values (for
+        example file sizes), multibyte integers are encoded in a
+        variable-length representation:
+          - Numbers in the range [0, 127] are copied as is, and take
+            one byte of space.
+          - Bigger numbers will occupy two or more bytes. All but the
+            last byte of the multibyte representation have the highest
+            (eighth) bit set.
+
+        For now, the value of the variable-length integers is limited
+        to 63 bits, which limits the encoded size of the integer to
+        nine bytes. These limits may be increased in the future if
+        needed.
+
+        The following C code illustrates encoding and decoding of
+        variable-length integers. The functions return the number of
+        bytes occupied by the integer (1-9), or zero on error.
+
+            #include <stddef.h>
+            #include <inttypes.h>
+
+            size_t
+            encode(uint8_t buf[static 9], uint64_t num)
+            {
+                if (num > UINT64_MAX / 2)
+                    return 0;
+
+                size_t i = 0;
+
+                while (num >= 0x80) {
+                    buf[i++] = (uint8_t)(num) | 0x80;
+                    num >>= 7;
+                }
+
+                buf[i++] = (uint8_t)(num);
+
+                return i;
+            }
+
+            size_t
+            decode(const uint8_t buf[], size_t size_max, uint64_t *num)
+            {
+                if (size_max == 0)
+                    return 0;
+
+                if (size_max > 9)
+                    size_max = 9;
+
+                *num = buf[0] & 0x7F;
+                size_t i = 0;
+
+                while (buf[i++] & 0x80) {
+                    if (i >= size_max || buf[i] == 0x00)
+                        return 0;
+
+                    *num |= (uint64_t)(buf[i] & 0x7F) << (i * 7);
+                }
+
+                return i;
+            }
+
+
+2. Overall Structure of .xz File
+
+        A standalone .xz files consist of one or more Streams which may
+        have Stream Padding between or after them:
+
+            +========+================+========+================+
+            | Stream | Stream Padding | Stream | Stream Padding | ...
+            +========+================+========+================+
+
+        The sizes of Stream and Stream Padding are always multiples
+        of four bytes, thus the size of every valid .xz file MUST be
+        a multiple of four bytes.
+
+        While a typical file contains only one Stream and no Stream
+        Padding, a decoder handling standalone .xz files SHOULD support
+        files that have more than one Stream or Stream Padding.
+
+        In contrast to standalone .xz files, when the .xz file format
+        is used as an internal part of some other file format or
+        communication protocol, it usually is expected that the decoder
+        stops after the first Stream, and doesn't look for Stream
+        Padding or possibly other Streams.
+
+
+2.1. Stream
+
+        +-+-+-+-+-+-+-+-+-+-+-+-+=======+=======+     +=======+
+        |     Stream Header     | Block | Block | ... | Block |
+        +-+-+-+-+-+-+-+-+-+-+-+-+=======+=======+     +=======+
+
+             +=======+-+-+-+-+-+-+-+-+-+-+-+-+
+        ---> | Index |     Stream Footer     |
+             +=======+-+-+-+-+-+-+-+-+-+-+-+-+
+
+        All the above fields have a size that is a multiple of four. If
+        Stream is used as an internal part of another file format, it
+        is RECOMMENDED to make the Stream start at an offset that is
+        a multiple of four bytes.
+
+        Stream Header, Index, and Stream Footer are always present in
+        a Stream. The maximum size of the Index field is 16 GiB (2^34).
+
+        There are zero or more Blocks. The maximum number of Blocks is
+        limited only by the maximum size of the Index field.
+
+        Total size of a Stream MUST be less than 8 EiB (2^63 bytes).
+        The same limit applies to the total amount of uncompressed
+        data stored in a Stream.
+
+        If an implementation supports handling .xz files with multiple
+        concatenated Streams, it MAY apply the above limits to the file
+        as a whole instead of limiting per Stream basis.
+
+
+2.1.1. Stream Header
+
+        +---+---+---+---+---+---+-------+------+--+--+--+--+
+        |  Header Magic Bytes   | Stream Flags |   CRC32   |
+        +---+---+---+---+---+---+-------+------+--+--+--+--+
+
+
+2.1.1.1. Header Magic Bytes
+
+        The first six (6) bytes of the Stream are so called Header
+        Magic Bytes. They can be used to identify the file type.
+
+            Using a C array and ASCII:
+            const uint8_t HEADER_MAGIC[6]
+                    = { 0xFD, '7', 'z', 'X', 'Z', 0x00 };
+
+            In plain hexadecimal:
+            FD 37 7A 58 5A 00
+
+        Notes:
+          - The first byte (0xFD) was chosen so that the files cannot
+            be erroneously detected as being in .lzma format, in which
+            the first byte is in the range [0x00, 0xE0].
+          - The sixth byte (0x00) was chosen to prevent applications
+            from misdetecting the file as a text file.
+
+        If the Header Magic Bytes don't match, the decoder MUST
+        indicate an error.
+
+
+2.1.1.2. Stream Flags
+
+        The first byte of Stream Flags is always a null byte. In the
+        future, this byte may be used to indicate a new Stream version
+        or other Stream properties.
+
+        The second byte of Stream Flags is a bit field:
+
+            Bit(s)  Mask  Description
+             0-3    0x0F  Type of Check (see Section 3.4):
+                              ID    Size      Check name
+                              0x00   0 bytes  None
+                              0x01   4 bytes  CRC32
+                              0x02   4 bytes  (Reserved)
+                              0x03   4 bytes  (Reserved)
+                              0x04   8 bytes  CRC64
+                              0x05   8 bytes  (Reserved)
+                              0x06   8 bytes  (Reserved)
+                              0x07  16 bytes  (Reserved)
+                              0x08  16 bytes  (Reserved)
+                              0x09  16 bytes  (Reserved)
+                              0x0A  32 bytes  SHA-256
+                              0x0B  32 bytes  (Reserved)
+                              0x0C  32 bytes  (Reserved)
+                              0x0D  64 bytes  (Reserved)
+                              0x0E  64 bytes  (Reserved)
+                              0x0F  64 bytes  (Reserved)
+             4-7    0xF0  Reserved for future use; MUST be zero for now.
+
+        Implementations SHOULD support at least the Check IDs 0x00
+        (None) and 0x01 (CRC32). Supporting other Check IDs is
+        OPTIONAL. If an unsupported Check is used, the decoder SHOULD
+        indicate a warning or error.
+
+        If any reserved bit is set, the decoder MUST indicate an error.
+        It is possible that there is a new field present which the
+        decoder is not aware of, and can thus parse the Stream Header
+        incorrectly.
+
+
+2.1.1.3. CRC32
+
+        The CRC32 is calculated from the Stream Flags field. It is
+        stored as an unsigned 32-bit little endian integer. If the
+        calculated value does not match the stored one, the decoder
+        MUST indicate an error.
+
+        The idea is that Stream Flags would always be two bytes, even
+        if new features are needed. This way old decoders will be able
+        to verify the CRC32 calculated from Stream Flags, and thus
+        distinguish between corrupt files (CRC32 doesn't match) and
+        files that the decoder doesn't support (CRC32 matches but
+        Stream Flags has reserved bits set).
+
+
+2.1.2. Stream Footer
+
+        +-+-+-+-+---+---+---+---+-------+------+----------+---------+
+        | CRC32 | Backward Size | Stream Flags | Footer Magic Bytes |
+        +-+-+-+-+---+---+---+---+-------+------+----------+---------+
+
+
+2.1.2.1. CRC32
+
+        The CRC32 is calculated from the Backward Size and Stream Flags
+        fields. It is stored as an unsigned 32-bit little endian
+        integer. If the calculated value does not match the stored one,
+        the decoder MUST indicate an error.
+
+        The reason to have the CRC32 field before the Backward Size and
+        Stream Flags fields is to keep the four-byte fields aligned to
+        a multiple of four bytes.
+
+
+2.1.2.2. Backward Size
+
+        Backward Size is stored as a 32-bit little endian integer,
+        which indicates the size of the Index field as multiple of
+        four bytes, minimum value being four bytes:
+
+            real_backward_size = (stored_backward_size + 1) * 4;
+
+        If the stored value does not match the real size of the Index
+        field, the decoder MUST indicate an error.
+
+        Using a fixed-size integer to store Backward Size makes
+        it slightly simpler to parse the Stream Footer when the
+        application needs to parse the Stream backwards.
+
+
+2.1.2.3. Stream Flags
+
+        This is a copy of the Stream Flags field from the Stream
+        Header. The information stored to Stream Flags is needed
+        when parsing the Stream backwards. The decoder MUST compare
+        the Stream Flags fields in both Stream Header and Stream
+        Footer, and indicate an error if they are not identical.
+
+
+2.1.2.4. Footer Magic Bytes
+
+        As the last step of the decoding process, the decoder MUST
+        verify the existence of Footer Magic Bytes. If they don't
+        match, an error MUST be indicated.
+
+            Using a C array and ASCII:
+            const uint8_t FOOTER_MAGIC[2] = { 'Y', 'Z' };
+
+            In hexadecimal:
+            59 5A
+
+        The primary reason to have Footer Magic Bytes is to make
+        it easier to detect incomplete files quickly, without
+        uncompressing. If the file does not end with Footer Magic Bytes
+        (excluding Stream Padding described in Section 2.2), it cannot
+        be undamaged, unless someone has intentionally appended garbage
+        after the end of the Stream.
+
+
+2.2. Stream Padding
+
+        Only the decoders that support decoding of concatenated Streams
+        MUST support Stream Padding.
+
+        Stream Padding MUST contain only null bytes. To preserve the
+        four-byte alignment of consecutive Streams, the size of Stream
+        Padding MUST be a multiple of four bytes. Empty Stream Padding
+        is allowed. If these requirements are not met, the decoder MUST
+        indicate an error.
+
+        Note that non-empty Stream Padding is allowed at the end of the
+        file; there doesn't need to be a new Stream after non-empty
+        Stream Padding. This can be convenient in certain situations
+        [GNU-tar].
+
+        The possibility of Stream Padding MUST be taken into account
+        when designing an application that parses Streams backwards,
+        and the application supports concatenated Streams.

+        ---> | Header Padding |   CRC32   |
+             +================+--+--+--+--+
+
+
+3.1.1. Block Header Size
+
+        This field overlaps with the Index Indicator field (see
+        Section 4.1).
+
+        This field contains the size of the Block Header field,
+        including the Block Header Size field itself. Valid values are
+        in the range [0x01, 0xFF], which indicate the size of the Block
+        Header as multiples of four bytes, minimum size being eight
+        bytes:
+
+            real_header_size = (encoded_header_size + 1) * 4;
+
+        If a Block Header bigger than 1024 bytes is needed in the
+        future, a new field can be added between the Block Header and
+        Compressed Data fields. The presence of this new field would
+        be indicated in the Block Header field.
+
+
+3.1.2. Block Flags
+
+        The Block Flags field is a bit field:
+
+            Bit(s)  Mask  Description
+             0-1    0x03  Number of filters (1-4)
+             2-5    0x3C  Reserved for future use; MUST be zero for now.
+              6     0x40  The Compressed Size field is present.
+              7     0x80  The Uncompressed Size field is present.
+
+        If any reserved bit is set, the decoder MUST indicate an error.
+        It is possible that there is a new field present which the
+        decoder is not aware of, and can thus parse the Block Header
+        incorrectly.
+
+
+3.1.3. Compressed Size
+
+        This field is present only if the appropriate bit is set in
+        the Block Flags field (see Section 3.1.2).
+
+        The Compressed Size field contains the size of the Compressed
+        Data field, which MUST be non-zero. Compressed Size is stored
+        using the encoding described in Section 1.2. If the Compressed
+        Size doesn't match the size of the Compressed Data field, the
+        decoder MUST indicate an error.
+
+
+3.1.4. Uncompressed Size
+
+        This field is present only if the appropriate bit is set in
+        the Block Flags field (see Section 3.1.2).
+
+        The Uncompressed Size field contains the size of the Block
+        after uncompressing. Uncompressed Size is stored using the
+        encoding described in Section 1.2. If the Uncompressed Size
+        does not match the real uncompressed size, the decoder MUST
+        indicate an error.
+
+        Storing the Compressed Size and Uncompressed Size fields serves
+        several purposes:
+          - The decoder knows how much memory it needs to allocate
+            for a temporary buffer in multithreaded mode.
+          - Simple error detection: wrong size indicates a broken file.
+          - Seeking forwards to a specific location in streamed mode.
+
+        It should be noted that the only reliable way to determine
+        the real uncompressed size is to uncompress the Block,
+        because the Block Header and Index fields may contain
+        (intentionally or unintentionally) invalid information.
+
+
+3.1.5. List of Filter Flags
+
+        +================+================+     +================+
+        | Filter 0 Flags | Filter 1 Flags | ... | Filter n Flags |
+        +================+================+     +================+
+
+        The number of Filter Flags fields is stored in the Block Flags
+        field (see Section 3.1.2).
+
+        The format of each Filter Flags field is as follows:
+
+            +===========+====================+===================+
+            | Filter ID | Size of Properties | Filter Properties |
+            +===========+====================+===================+
+
+        Both Filter ID and Size of Properties are stored using the
+        encoding described in Section 1.2. Size of Properties indicates
+        the size of the Filter Properties field as bytes. The list of
+        officially defined Filter IDs and the formats of their Filter
+        Properties are described in Section 5.3.
+
+        Filter IDs greater than or equal to 0x4000_0000_0000_0000
+        (2^62) are reserved for implementation-specific internal use.
+        These Filter IDs MUST never be used in List of Filter Flags.
+
+
+3.1.6. Header Padding
+
+        This field contains as many null byte as it is needed to make
+        the Block Header have the size specified in Block Header Size.
+        If any of the bytes are not null bytes, the decoder MUST
+        indicate an error. It is possible that there is a new field
+        present which the decoder is not aware of, and can thus parse
+        the Block Header incorrectly.
+
+
+3.1.7. CRC32
+
+        The CRC32 is calculated over everything in the Block Header
+        field except the CRC32 field itself. It is stored as an
+        unsigned 32-bit little endian integer. If the calculated
+        value does not match the stored one, the decoder MUST indicate
+        an error.
+
+        By verifying the CRC32 of the Block Header before parsing the
+        actual contents allows the decoder to distinguish between
+        corrupt and unsupported files.
+
+
+3.2. Compressed Data
+
+        The format of Compressed Data depends on Block Flags and List
+        of Filter Flags. Excluding the descriptions of the simplest
+        filters in Section 5.3, the format of the filter-specific
+        encoded data is out of scope of this document.
+
+
+3.3. Block Padding
+
+        Block Padding MUST contain 0-3 null bytes to make the size of
+        the Block a multiple of four bytes. This can be needed when
+        the size of Compressed Data is not a multiple of four. If any
+        of the bytes in Block Padding are not null bytes, the decoder
+        MUST indicate an error.
+
+
+3.4. Check
+
+        The type and size of the Check field depends on which bits
+        are set in the Stream Flags field (see Section 2.1.1.2).
+
+        The Check, when used, is calculated from the original
+        uncompressed data. If the calculated Check does not match the
+        stored one, the decoder MUST indicate an error. If the selected
+        type of Check is not supported by the decoder, it SHOULD
+        indicate a warning or error.
+
+
+4. Index
+
+        +-----------------+===================+
+        | Index Indicator | Number of Records |
+        +-----------------+===================+
+
+             +=================+===============+-+-+-+-+
+        ---> | List of Records | Index Padding | CRC32 |
+             +=================+===============+-+-+-+-+
+
+        Index serves several purposes. Using it, one can
+          - verify that all Blocks in a Stream have been processed;
+          - find out the uncompressed size of a Stream; and
+          - quickly access the beginning of any Block (random access).
+
+
+4.1. Index Indicator
+
+        This field overlaps with the Block Header Size field (see
+        Section 3.1.1). The value of Index Indicator is always 0x00.
+
+
+4.2. Number of Records
+
+        This field indicates how many Records there are in the List
+        of Records field, and thus how many Blocks there are in the
+        Stream. The value is stored using the encoding described in
+        Section 1.2. If the decoder has decoded all the Blocks of the
+        Stream, and then notices that the Number of Records doesn't
+        match the real number of Blocks, the decoder MUST indicate an
+        error.
+
+
+4.3. List of Records
+
+        List of Records consists of as many Records as indicated by the
+        Number of Records field:
+
+            +========+========+
+            | Record | Record | ...
+            +========+========+
+
+        Each Record contains information about one Block:
+
+            +===============+===================+
+            | Unpadded Size | Uncompressed Size |
+            +===============+===================+
+
+        If the decoder has decoded all the Blocks of the Stream, it
+        MUST verify that the contents of the Records match the real
+        Unpadded Size and Uncompressed Size of the respective Blocks.
+
+        Implementation hint: It is possible to verify the Index with
+        constant memory usage by calculating for example SHA-256 of
+        both the real size values and the List of Records, then
+        comparing the hash values. Implementing this using
+        non-cryptographic hash like CRC32 SHOULD be avoided unless
+        small code size is important.
+
+        If the decoder supports random-access reading, it MUST verify
+        that Unpadded Size and Uncompressed Size of every completely
+        decoded Block match the sizes stored in the Index. If only
+        partial Block is decoded, the decoder MUST verify that the
+        processed sizes don't exceed the sizes stored in the Index.
+
+
+4.3.1. Unpadded Size
+
+        This field indicates the size of the Block excluding the Block
+        Padding field. That is, Unpadded Size is the size of the Block
+        Header, Compressed Data, and Check fields. Unpadded Size is
+        stored using the encoding described in Section 1.2. The value
+        MUST never be zero; with the current structure of Blocks, the
+        actual minimum value for Unpadded Size is five.
+
+        Implementation note: Because the size of the Block Padding
+        field is not included in Unpadded Size, calculating the total
+        size of a Stream or doing random-access reading requires
+        calculating the actual size of the Blocks by rounding Unpadded
+        Sizes up to the next multiple of four.
+
+        The reason to exclude Block Padding from Unpadded Size is to
+        ease making a raw copy of Compressed Data without Block
+        Padding. This can be useful, for example, if someone wants
+        to convert Streams to some other file format quickly.
+
+
+4.3.2. Uncompressed Size
+
+        This field indicates the Uncompressed Size of the respective
+        Block as bytes. The value is stored using the encoding
+        described in Section 1.2.
+
+
+4.4. Index Padding
+
+        This field MUST contain 0-3 null bytes to pad the Index to
+        a multiple of four bytes. If any of the bytes are not null
+        bytes, the decoder MUST indicate an error.
+
+
+4.5. CRC32
+
+        The CRC32 is calculated over everything in the Index field
+        except the CRC32 field itself. The CRC32 is stored as an
+        unsigned 32-bit little endian integer. If the calculated
+        value does not match the stored one, the decoder MUST indicate
+        an error.
+
+
+5. Filter Chains
+
+        The Block Flags field defines how many filters are used. When
+        more than one filter is used, the filters are chained; that is,
+        the output of one filter is the input of another filter. The
+        following figure illustrates the direction of data flow.
+
+                    v   Uncompressed Data   ^
+                    |       Filter 0        |
+            Encoder |       Filter 1        | Decoder
+                    |       Filter n        |
+                    v    Compressed Data    ^
+
+
+5.1. Alignment
+
+        Alignment of uncompressed input data is usually the job of
+        the application producing the data. For example, to get the
+        best results, an archiver tool should make sure that all
+        PowerPC executable files in the archive stream start at
+        offsets that are multiples of four bytes.
+
+        Some filters, for example LZMA2, can be configured to take
+        advantage of specified alignment of input data. Note that
+        taking advantage of aligned input can be beneficial also when
+        a filter is not the first filter in the chain. For example,
+        if you compress PowerPC executables, you may want to use the
+        PowerPC filter and chain that with the LZMA2 filter. Because
+        not only the input but also the output alignment of the PowerPC
+        filter is four bytes, it is now beneficial to set LZMA2
+        settings so that the LZMA2 encoder can take advantage of its
+        four-byte-aligned input data.
+
+        The output of the last filter in the chain is stored to the
+        Compressed Data field, which is is guaranteed to be aligned
+        to a multiple of four bytes relative to the beginning of the
+        Stream. This can increase
+          - speed, if the filtered data is handled multiple bytes at
+            a time by the filter-specific encoder and decoder,
+            because accessing aligned data in computer memory is
+            usually faster; and
+          - compression ratio, if the output data is later compressed
+            with an external compression tool.
+
+
+5.2. Security
+
+        If filters would be allowed to be chained freely, it would be
+        possible to create malicious files, that would be very slow to
+        decode. Such files could be used to create denial of service
+        attacks.
+
+        Slow files could occur when multiple filters are chained:
+
+            v   Compressed input data
+            |   Filter 1 decoder (last filter)
+            |   Filter 0 decoder (non-last filter)
+            v   Uncompressed output data
+
+        The decoder of the last filter in the chain produces a lot of
+        output from little input. Another filter in the chain takes the
+        output of the last filter, and produces very little output
+        while consuming a lot of input. As a result, a lot of data is
+        moved inside the filter chain, but the filter chain as a whole
+        gets very little work done.
+
+        To prevent this kind of slow files, there are restrictions on
+        how the filters can be chained. These restrictions MUST be
+        taken into account when designing new filters.
+
+        The maximum number of filters in the chain has been limited to
+        four, thus there can be at maximum of three non-last filters.
+        Of these three non-last filters, only two are allowed to change
+        the size of the data.
+
+        The non-last filters, that change the size of the data, MUST
+        have a limit how much the decoder can compress the data: the
+        decoder SHOULD produce at least n bytes of output when the
+        filter is given 2n bytes of input. This  limit is not
+        absolute, but significant deviations MUST be avoided.
+
+        The above limitations guarantee that if the last filter in the
+        chain produces 4n bytes of output, the chain as a whole will
+        produce at least n bytes of output.
+
+
+5.3. Filters
+
+5.3.1. LZMA2
+
+        LZMA (Lempel-Ziv-Markov chain-Algorithm) is a general-purpose
+        compression algorithm with high compression ratio and fast
+        decompression. LZMA is based on LZ77 and range coding
+        algorithms.
+
+        LZMA2 is an extension on top of the original LZMA. LZMA2 uses
+        LZMA internally, but adds support for flushing the encoder,
+        uncompressed chunks, eases stateful decoder implementations,
+        and improves support for multithreading. Thus, the plain LZMA
+        will not be supported in this file format.
+
+            Filter ID:                  0x21
+            Size of Filter Properties:  1 byte
+            Changes size of data:       Yes
+            Allow as a non-last filter: No
+            Allow as the last filter:   Yes
+
+            Preferred alignment:
+                Input data:             Adjustable to 1/2/4/8/16 byte(s)
+                Output data:            1 byte
+
+        The format of the one-byte Filter Properties field is as
+        follows:
+
+            Bits   Mask   Description
+            0-5    0x3F   Dictionary Size
+            6-7    0xC0   Reserved for future use; MUST be zero for now.
+
+        Dictionary Size is encoded with one-bit mantissa and five-bit
+        exponent. The smallest dictionary size is 4 KiB and the biggest
+        is 4 GiB.
+
+            Raw value   Mantissa   Exponent   Dictionary size
+                0           2         11         4 KiB
+                1           3         11         6 KiB
+                2           2         12         8 KiB
+                3           3         12        12 KiB
+                4           2         13        16 KiB
+                5           3         13        24 KiB
+                6           2         14        32 KiB
+              ...         ...        ...      ...
+               35           3         27       768 MiB
+               36           2         28      1024 MiB
+               37           3         29      1536 MiB
+               38           2         30      2048 MiB
+               39           3         30      3072 MiB
+               40           2         31      4096 MiB - 1 B
+
+        Instead of having a table in the decoder, the dictionary size
+        can be decoded using the following C code:
+
+            const uint8_t bits = get_dictionary_flags() & 0x3F;
+            if (bits > 40)
+                return DICTIONARY_TOO_BIG; // Bigger than 4 GiB
+
+            uint32_t dictionary_size;
+            if (bits == 40) {
+                dictionary_size = UINT32_MAX;
+            } else {
+                dictionary_size = 2 | (bits & 1);
+                dictionary_size <<= bits / 2 + 11;
+            }
+
+
+5.3.2. Branch/Call/Jump Filters for Executables
+
+        These filters convert relative branch, call, and jump
+        instructions to their absolute counterparts in executable
+        files. This conversion increases redundancy and thus
+        compression ratio.
+
+            Size of Filter Properties:  0 or 4 bytes
+            Changes size of data:       No
+            Allow as a non-last filter: Yes
+            Allow as the last filter:   No
+
+        Below is the list of filters in this category. The alignment
+        is the same for both input and output data.
+
+            Filter ID   Alignment   Description
+              0x04       1 byte     x86 filter (BCJ)
+              0x05       4 bytes    PowerPC (big endian) filter
+              0x06      16 bytes    IA64 filter
+              0x07       4 bytes    ARM filter [1]
+              0x08       2 bytes    ARM Thumb filter [1]
+              0x09       4 bytes    SPARC filter
+              0x0A       4 bytes    ARM64 filter [2]
+
+              [1] These are for little endian instruction encoding.
+                  This must not be confused with data endianness.
+                  A processor configured for big endian data access
+                  may still use little endian instruction encoding.
+                  The filters don't care about the data endianness.
+
+              [2] 4096-byte alignment gives the best results
+                  because the address in the ADRP instruction
+                  is a multiple of 4096 bytes.
+
+        If the size of Filter Properties is four bytes, the Filter
+        Properties field contains the start offset used for address
+        conversions. It is stored as an unsigned 32-bit little endian
+        integer. The start offset MUST be a multiple of the alignment
+        of the filter as listed in the table above; if it isn't, the
+        decoder MUST indicate an error. If the size of Filter
+        Properties is zero, the start offset is zero.
+
+        Setting the start offset may be useful if an executable has
+        multiple sections, and there are many cross-section calls.
+        Taking advantage of this feature usually requires usage of
+        the Subblock filter, whose design is not complete yet.
+
+
+5.3.3. Delta
+
+        The Delta filter may increase compression ratio when the value
+        of the next byte correlates with the value of an earlier byte
+        at specified distance.
+
+            Filter ID:                  0x03
+            Size of Filter Properties:  1 byte
+            Changes size of data:       No
+            Allow as a non-last filter: Yes
+            Allow as the last filter:   No
+
+            Preferred alignment:
+                Input data:             1 byte
+                Output data:            Same as the original input data
+
+        The Properties byte indicates the delta distance, which can be
+        1-256 bytes backwards from the current byte: 0x00 indicates
+        distance of 1 byte and 0xFF distance of 256 bytes.
+
+
+5.3.3.1. Format of the Encoded Output
+
+        The code below illustrates both encoding and decoding with
+        the Delta filter.
+
+            // Distance is in the range [1, 256].
+            const unsigned int distance = get_properties_byte() + 1;
+            uint8_t pos = 0;
+            uint8_t delta[256];
+
+            memset(delta, 0, sizeof(delta));
+
+            while (1) {
+                const int byte = read_byte();
+                if (byte == EOF)
+                    break;
+
+                uint8_t tmp = delta[(uint8_t)(distance + pos)];
+                if (is_encoder) {
+                    tmp = (uint8_t)(byte) - tmp;
+                    delta[pos] = (uint8_t)(byte);
+                } else {
+                    tmp = (uint8_t)(byte) + tmp;
+                    delta[pos] = tmp;
+                }
+
+                write_byte(tmp);
+                --pos;
+            }
+
+
+5.4. Custom Filter IDs
+
+        If a developer wants to use custom Filter IDs, there are two
+        choices. The first choice is to contact Lasse Collin and ask
+        him to allocate a range of IDs for the developer.
+
+        The second choice is to generate a 40-bit random integer
+        which the developer can use as a personal Developer ID.
+        To minimize the risk of collisions, Developer ID has to be
+        a randomly generated integer, not manually selected "hex word".
+        The following command, which works on many free operating
+        systems, can be used to generate Developer ID:
+
+            dd if=/dev/urandom bs=5 count=1 | hexdump
+
+        The developer can then use the Developer ID to create unique
+        (well, hopefully unique) Filter IDs.
+
+            Bits    Mask                    Description
+             0-15   0x0000_0000_0000_FFFF   Filter ID
+            16-55   0x00FF_FFFF_FFFF_0000   Developer ID
+            56-62   0x3F00_0000_0000_0000   Static prefix: 0x3F
+
+        The resulting 63-bit integer will use 9 bytes of space when
+        stored using the encoding described in Section 1.2. To get
+        a shorter ID, see the beginning of this Section how to
+        request a custom ID range.
+
+
+5.4.1. Reserved Custom Filter ID Ranges
+
+        Range                       Description
+        0x0000_0300 - 0x0000_04FF   Reserved to ease .7z compatibility
+        0x0002_0000 - 0x0007_FFFF   Reserved to ease .7z compatibility
+        0x0200_0000 - 0x07FF_FFFF   Reserved to ease .7z compatibility
+
+
+6. Cyclic Redundancy Checks
+
+        There are several incompatible variations to calculate CRC32
+        and CRC64. For simplicity and clarity, complete examples are
+        provided to calculate the checks as they are used in this file
+        format. Implementations MAY use different code as long as it
+        gives identical results.
+
+        The program below reads data from standard input, calculates
+        the CRC32 and CRC64 values, and prints the calculated values
+        as big endian hexadecimal strings to standard output.
+
+            #include <stddef.h>
+            #include <inttypes.h>
+            #include <stdio.h>
+
+            uint32_t crc32_table[256];
+            uint64_t crc64_table[256];
+

+Building XZ Utils for DOS
+=========================
+
+Introduction
+
+    This document explains how to build XZ Utils for DOS using DJGPP.
+    The resulting binaries should run at least on various DOS versions
+    and under Windows 95/98/98SE/ME.
+
+    This is somewhat experimental and has got very little testing.
+
+    Note: Makefile and config.h are updated only now and then. This
+    means that if you checked out a development version, building for
+    DOS might not work without updating Makefile and config.h first.
+
+
+Getting and Installing DJGPP
+
+    You may use <https://www.delorie.com/djgpp/zip-picker.html> to help
+    deciding what to download. If you are only interested in building
+    XZ Utils, the zip-picker may list files that you don't strictly
+    need. However, using the zip-picker can still be worth it to get a
+    nice short summary of installation instructions (they can be found
+    from readme.1st too).
+
+    For a more manual method, first select a mirror from
+    <https://www.delorie.com/djgpp/getting.html> and go the
+    subdirectory named "current". You need the following files:
+
+        unzip32.exe  (if you don't already have a LFN-capable unzipper)
+        v2/djdev205.zip
+        v2gnu/bnu234b.zip
+        v2gnu/gcc920b.zip
+        v2gnu/mak43b.zip
+        v2misc/csdpmi7b.zip
+
+    If newer versions are available, probably you should try them first.
+    Note that versions older than djdev205.zip aren't supported. Also
+    note that you want csdpmi7b.zip even if you run under Windows or
+    DOSEMU because the XZ Utils Makefile will embed cwsdstub.exe to
+    the resulting xz.exe.
+
+    See the instructions in readme.1st found from djdev205.zip. Here's
+    a short summary, but you should still read readme.1st.
+
+        C:\> mkdir DJGPP
+        C:\> cd DJGPP
+        C:\DJGPP> c:\download\unzip32 c:\download\djdev205.zip
+        C:\DJGPP> c:\download\unzip32 c:\download\bnu234b.zip
+        C:\DJGPP> c:\download\unzip32 c:\download\gcc920b.zip
+        C:\DJGPP> c:\download\unzip32 c:\download\mak43b.zip
+        C:\DJGPP> c:\download\unzip32 c:\download\csdpmi7b.zip
+
+        C:\DJGPP> set PATH=C:\DJGPP\BIN;%PATH%
+        C:\DJGPP> set DJGPP=C:\DJGPP\DJGPP.ENV
+
+    You may want to add the last two lines into AUTOEXEC.BAT or have,
+    for example, DJGPP.BAT which you can run before using DJGPP.
+
+    Make sure you use completely upper case path in the DJGPP environment
+    variable. This is not required by DJGPP, but the XZ Utils Makefile is
+    a bit stupid and expects that everything in DJGPP environment variable
+    is uppercase.
+
+
+Building
+
+    You need to have an environment that supports long filenames (LFN).
+    Once you have built XZ Utils, the resulting binaries can be run
+    without long filename support.
+
+    Run "make" in this directory (the directory containing this
+    INSTALL.txt). You should get xz.exe (and a bunch of temporary files).
+    Other tools are not built. Having e.g. xzdec.exe doesn't save much
+    space compared to xz.exe because the DJGPP runtime makes the .exe
+    quite big anyway.

+XZ Utils on DOS
+===============
+
+DOS-specific filename handling
+
+    xz detects at runtime if long filename (LFN) support is
+    available and will use it by default. It can be disabled by
+    setting an environment variable:
+
+        set lfn=n
+
+    When xz is in LFN mode, it behaves pretty much the same as it
+    does on other operating systems. Examples:
+
+        xz foo.tar          -> foo.tar.xz
+        xz -d foo.tar.xz    -> foo.tar
+
+        xz -F lzma foo.tar  -> foo.tar.lzma
+        xz -d foo.tar.lzma  -> foo.tar
+
+    When LFN support isn't available or it is disabled with LFN=n
+    environment setting, xz works in short filename (SFN) mode. This
+    affects filename suffix handling when compressing.
+
+    When compressing to the .xz format in SFN mode:
+
+      - Files without an extension get .xz just like on LFN systems.
+
+      - *.tar files become *.txz (shorthand for *.tar.xz). *.txz
+        is recognized by xz on all supported operating systems.
+        (Try to avoid confusing this with gzipped .txt files.)
+
+      - Files with 1-3 character extension have their extension modified
+        so that the last character is a dash ("-"). If the extension
+        is already three characters, the last character is lost. The
+        resulting *.?- or *.??- filename is recognized in LFN mode, but
+        it isn't recognized by xz on other operating systems.
+
+    Examples:
+
+        xz foo              -> foo.xz     |   xz -d foo.xz    -> foo
+        xz foo.tar          -> foo.txz    |   xz -d foo.txz   -> foo.tar
+        xz foo.c            -> foo.c-     |   xz -d foo.c-    -> foo.c
+        xz read.me          -> read.me-   |   xz -d read.me-  -> read.me
+        xz foo.txt          -> foo.tx-    |   xz -d foo.tx-   -> foo.tx   !
+
+    Note that in the last example above, the third character of the
+    filename extension is lost.
+
+    When compressing to the legacy .lzma format in SFN mode:
+
+      - *.tar files become *.tlz (shorthand for *.tar.lzma). *.tlz
+        is recognized by xz on all supported operating systems.
+
+      - Other files become *.lzm. The original filename extension
+        is lost. *.lzm is recognized also in LFN mode, but it is not
+        recognized by xz on other operating systems.
+
+    Examples:
+
+        xz -F lzma foo      -> foo.lzm    |   xz -d foo.lzm   -> foo
+        xz -F lzma foo.tar  -> foo.tlz    |   xz -d foo.tlz   -> foo.tar
+        xz -F lzma foo.c    -> foo.lzm    |   xz -d foo.lzm   -> foo      !
+        xz -F lzma read.me  -> read.lzm   |   xz -d read.lzm  -> read     !
+        xz -F lzma foo.txt  -> foo.lzm    |   xz -d foo.lzm   -> foo      !
+
+    When compressing with a custom suffix (-S .SUF, --suffix=.SUF) to
+    any file format:
+
+      - If the suffix begins with a dot, the filename extension is
+        replaced with the new suffix. The original extension is lost.
+
+      - If the suffix doesn't begin with a dot and the filename has no
+        extension and the filename given on the command line doesn't
+        have a dot at the end, the custom suffix is appended just like
+        on LFN systems.
+
+      - If the suffix doesn't begin with a dot and the filename has
+        an extension (or an extension-less filename is given with a dot
+        at the end), the last 1-3 characters of the filename extension
+        may get overwritten to fit the given custom suffix.
+
+    Examples:
+
+        xz -S x foo        -> foox      |  xz -dS x foox      -> foo
+        xz -S x foo.       -> foo.x     |  xz -dS x foo.x     -> foo
+        xz -S .x foo       -> foo.x     |  xz -dS .x foo.x    -> foo
+        xz -S .x foo.      -> foo.x     |  xz -dS .x foo.x    -> foo
+        xz -S x.y foo      -> foox.y    |  xz -dS x.y foox.y  -> foo
+        xz -S .a foo.c     -> foo.a     |  xz -dS .a foo.a    -> foo      !
+        xz -S a  foo.c     -> foo.ca    |  xz -dS a foo.ca    -> foo.c
+        xz -S ab foo.c     -> foo.cab   |  xz -dS ab foo.cab  -> foo.c
+        xz -S ab read.me   -> read.mab  |  xz -dS ab read.mab -> read.m   !
+        xz -S ab foo.txt   -> foo.tab   |  xz -dS ab foo.tab  -> foo.t    !
+        xz -S abc foo.txt  -> foo.abc   |  xz -dS abc foo.abc -> foo      !
+
+    When decompressing, the suffix handling in SFN mode is the same as
+    in LFN mode. The DOS-specific filenames *.lzm, *.?-, and *.??- are
+    recognized also in LFN mode.
+
+    xz handles certain uncommon situations safely:
+
+      - If the generated output filename refers to the same file as
+        the input file, xz detects this and refuses to compress or
+        decompress the input file even if --force is used. This can
+        happen when giving an overlong filename in SFN mode. E.g.
+        "xz -S x foo.texinfo" would try to write to foo.tex which on
+        SFN system is the same file as foo.texinfo.
+
+      - If the generated output filename is a special file like "con"
+        or "prn", xz detects this and refuses to compress or decompress
+        the input file even if --force is used.
+
+
+Bugs
+
+    xz doesn't necessarily work in Dosbox. It should work in DOSEMU.
+
+    Pressing Ctrl-c or Ctrl-Break won't remove the incomplete target file
+    when running under Windows XP Command Prompt (something goes wrong
+    with SIGINT handling). It works correctly under Windows 95/98/98SE/ME.

+# 7z2lzma.bash is very primitive .7z to .lzma converter. The input file must
+# have exactly one LZMA compressed stream, which has been created with the
+# default lc, lp, and pb values. The CRC32 in the .7z archive is not checked,
+# and the script may seem to succeed while it actually created a corrupt .lzma
+# file. You should always try uncompressing both the original .7z and the
+# created .lzma and compare that the output is identical.
+#
+# This script requires basic GNU tools and 7z or 7za tool from p7zip.

+/* Scan elements of ARGV (whose length is ARGC) for option characters
+   given in OPTSTRING.
+
+   If an element of ARGV starts with '-', and is not exactly "-" or "--",
+   then it is an option element.  The characters of this element
+   (aside from the initial '-') are option characters.  If `getopt'
+   is called repeatedly, it returns successively each of the option characters
+   from each of the option elements.
+
+   If `getopt' finds another option character, it returns that character,
+   updating `optind' and `nextchar' so that the next call to `getopt' can
+   resume the scan with the following option character or ARGV-element.
+
+   If there are no more option characters, `getopt' returns -1.
+   Then `optind' is the index in ARGV of the first ARGV-element
+   that is not an option.  (The ARGV-elements have been permuted
+   so that those that are not options now come last.)
+
+   OPTSTRING is a string containing the legitimate option characters.
+   If an option character is seen that is not listed in OPTSTRING,
+   return '?' after printing an error message.  If you set `opterr' to
+   zero, the error message is suppressed but we still return '?'.
+
+   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+   so the following text in the same ARGV-element, or the text of the following
+   ARGV-element, is returned in `optarg'.  Two colons mean an option that
+   wants an optional arg; if there is text in the current ARGV-element,
+   it is returned in `optarg', otherwise `optarg' is set to zero.
+
+   If OPTSTRING starts with `-' or `+', it requests different methods of
+   handling the non-option ARGV-elements.
+   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+   Long-named options begin with `--' instead of `-'.
+   Their names may be abbreviated as long as the abbreviation is unique
+   or is an exact match for some defined option.  If they have an
+   argument, it follows the option name in the same ARGV-element, separated
+   from the option name by a `=', or else the in next ARGV-element.
+   When `getopt' finds a long-named option, it returns 0 if that option's
+   `flag' field is nonzero, the value of the option's `val' field
+   if the `flag' field is zero.
+
+   LONGOPTS is a vector of `struct option' terminated by an
+   element containing a name which is zero.
+
+   LONGIND returns the index in LONGOPT of the long-named option found.
+   It is only valid when a long-named option has been found by the most
+   recent call.
+
+   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+   long-named options.
+
+   If POSIXLY_CORRECT is nonzero, behave as if the POSIXLY_CORRECT
+   environment variable were set.  */

+#
+# DESCRIPTION
+#
+#   This macro searches for an installed Capsicum header and library,
+#   and if found:
+#     - AC_DEFINE([HAVE_CAPSICUM]) is called.
+#     - AC_DEFINE([HAVE_SYS_CAPSICUM_H]) is called if <sys/capsicum.h>
+#       is present (otherwise <sys/capability.h> must be used).
+#     - CAPSICUM_LIB is set to the -l option needed to link Capsicum support,
+#       and AC_SUBST([CAPSICUM_LIB]) is called.
+#     - The shell commands in ACTION-IF-FOUND are run. The default
+#       ACTION-IF-FOUND prepends ${CAPSICUM_LIB} into LIBS. If you don't
+#       want to modify LIBS and don't need to run any other commands either,
+#       use a colon as ACTION-IF-FOUND.
+#
+#   If Capsicum support isn't found:
+#     - The shell commands in ACTION-IF-NOT-FOUND are run. The default
+#       ACTION-IF-NOT-FOUND calls AC_MSG_WARN to print a warning that
+#       Capsicum support wasn't found.
+#
+#   You should use autoheader to include a definition for the symbols above
+#   in a config.h file.
+#
+#   Sample usage in a C/C++ source is as follows:
+#
+#     #ifdef HAVE_CAPSICUM
+#     # ifdef HAVE_SYS_CAPSICUM_H

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC and PTHREAD_CXX to any special C compiler that is
+#   needed for multi-threaded programs (defaults to the value of CC
+#   respectively CXX otherwise). (This is necessary on e.g. AIX to use the
+#   special cc_r/CC_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also to link with them as well. For example, you might link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#   $PTHREAD_CXX $CXXFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threaded programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#     CXX="$PTHREAD_CXX"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
+#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+dnl INTLSYMBOL must be one of 'external', 'use-libtool'.
+dnl    INTLSYMBOL should be 'external' for packages other than GNU gettext, and
+dnl    'use-libtool' for the packages 'gettext-runtime' and 'gettext-tools'.
+dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl    depending on --{enable,disable}-{shared,static} and on the presence of
+dnl    AM-DISABLE-SHARED).
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function
+dnl    will be ignored.  If NEEDSYMBOL is specified and is
+dnl    'need-formatstring-macros', then GNU gettext implementations that don't
+dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries.  If empty,
+dnl    the value '$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl    and used.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl    Catalog format: none
+dnl    Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+
+dnl Sets the HOST_CPU variable to the canonical name of the CPU.
+dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
+dnl C language ABI (application binary interface).
+dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
+dnl config.h.
+dnl
+dnl This canonical name can be used to select a particular assembly language
+dnl source file that will interoperate with C code on the given host.
+dnl
+dnl For example:
+dnl * 'i386' and 'sparc' are different canonical names, because code for i386
+dnl   will not run on SPARC CPUs and vice versa. They have different
+dnl   instruction sets.
+dnl * 'sparc' and 'sparc64' are different canonical names, because code for
+dnl   'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
+dnl   contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
+dnl   instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
+dnl   mode, but not both.
+dnl * 'mips' and 'mipsn32' are different canonical names, because they use
+dnl   different argument passing and return conventions for C functions, and
+dnl   although the instruction set of 'mips' is a large subset of the
+dnl   instruction set of 'mipsn32'.
+dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
+dnl   different sizes for the C types like 'int' and 'void *', and although
+dnl   the instruction sets of 'mipsn32' and 'mips64' are the same.
+dnl * The same canonical name is used for different endiannesses. You can
+dnl   determine the endianness through preprocessor symbols:
+dnl   - 'arm': test __ARMEL__.
+dnl   - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
+dnl   - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN.
+dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
+dnl   (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
+dnl   - Instructions that do not exist on all of these CPUs (cmpxchg,
+dnl     MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
+dnl     assembly language source files use such instructions, you will
+dnl     need to make the distinction.
+dnl   - Speed of execution of the common instruction set is reasonable across
+dnl     the entire family of CPUs. If you have assembly language source files
+dnl     that are optimized for particular CPU types (like GNU gmp has), you
+dnl     will need to make the distinction.

+# DESCRIPTION
+#
+#   Check how to get the amount of physical memory.
+#   This information is used in tuklib_physmem.c.
+#
+#   Supported methods:
+#
+#     - Windows (including Cygwin), OS/2, DJGPP (DOS), OpenVMS, AROS,
+#       and QNX have operating-system specific functions.
+#
+#     - AIX has _system_configuration.physmem.
+#
+#     - sysconf() works on GNU/Linux and Solaris, and possibly on
+#       some BSDs.
+#
+#     - BSDs use sysctl().
+#
+#     - Tru64 uses getsysinfo().
+#
+#     - HP-UX uses pstat_getstatic().
+#
+#     - IRIX has setinvent_r(), getinvent_r(), and endinvent_r().
+#
+#     - sysinfo() works on Linux/dietlibc and probably on other Linux
+#       systems whose libc may lack sysconf().

+anstelle der Namen \fBunxz\fP und \fBxzcat\fP verwenden.
+.
+.SH BESCHREIBUNG
+\fBxz\fP ist ein Allzweckwerkzeug zur Datenkompression, dessen
+Befehlszeilensyntax denen von \fBgzip\fP(1) und \fBbzip2\fP(1) ähnelt. Das native
+Dateiformat ist das \fB.xz\fP\-Format, aber das veraltete, von den
+LZMA\-Dienstprogrammen verwendete Format sowie komprimierte Rohdatenströme
+ohne Containerformat\-Header werden ebenfalls unterstützt. Außerdem wird die
+Dekompression des von \fBlzip\fP verwendeten \fB.lz\fP\-Formats unterstützt.
+.PP
+\fBxz\fP komprimiert oder dekomprimiert jede \fIDatei\fP entsprechend des
+gewählten Vorgangsmodus. Falls entweder \fB\-\fP oder keine Datei angegeben ist,
+liest \fBxz\fP aus der Standardeingabe und leitet die verarbeiteten Dateien in
+die Standardausgabe. Wenn die Standardausgabe kein Terminal ist, verweigert
+\fBxz\fP das Schreiben komprimierter Daten in die Standardausgabe. Dabei wird
+eine Fehlermeldung angezeigt und die \fIDatei\fP übersprungen. Ebenso
+verweigert \fBxz\fP das Lesen komprimierter Daten aus der Standardeingabe, wenn
+diese ein Terminal ist.
+.PP
+\fIDateien\fP, die nicht als \fB\-\fP angegeben sind, werden in eine neue Datei
+geschrieben, deren Name aus dem Namen der Quell\-\fIDatei\fP abgeleitet wird
+(außer wenn \fB\-\-stdout\fP angegeben ist):
+.IP \(bu 3
+Bei der Kompression wird das Suffix des Formats der Zieldatei (\fB.xz\fP oder
+\&\fB.lzma\fP) an den Namen der Quelldatei angehängt und so der Name der
+Zieldatei gebildet.
+.IP \(bu 3
+Bei der Dekompression wird das Suffix \fB.xz\fP, \fB.lzma\fP oder \fB.lz\fP vom
+Dateinamen entfernt und so der Name der Zieldatei gebildet. Außerdem erkennt
+\fBxz\fP die Suffixe \fB.txz\fP und \fB.tlz\fP und ersetzt diese durch \fB.tar\fP.
+.PP
+Wenn die Zieldatei bereits existiert, wird eine Fehlermeldung angezeigt und
+die \fIDatei\fP übersprungen.
+.PP
+Außer beim Schreiben in die Standardausgabe zeigt \fBxz\fP eine Warnung an und
+überspringt die \fIDatei\fP, wenn eine der folgenden Bedingungen zutreffend
+ist:
+.IP \(bu 3
+Die \fIDatei\fP ist keine reguläre Datei. Symbolischen Verknüpfungen wird nicht
+gefolgt und diese daher nicht zu den regulären Dateien gezählt.
+.IP \(bu 3
+Die \fIDatei\fP hat mehr als eine harte Verknüpfung.
+.IP \(bu 3
+Für die \fIDatei\fP ist das »setuid«\-, »setgid«\- oder »sticky«\-Bit gesetzt.
+.IP \(bu 3
+Der Aktionsmodus wird auf Kompression gesetzt und die \fIDatei\fP hat bereits
+das Suffix des Zieldateiformats (\fB.xz\fP oder \fB.txz\fP beim Komprimieren in
+das \fB.xz\fP\-Format und \fB.lzma\fP oder \fB.tlz\fP beim Komprimieren in das
+\&\fB.lzma\fP\-Format).
+.IP \(bu 3
+Der Aktionsmodus wird auf Dekompression gesetzt und die \fIDatei\fP hat nicht
+das Suffix eines der unterstützten Zieldateiformate (\fB.xz\fP, \fB.txz\fP,
+\&\fB.lzma\fP, \fB.tlz\fP oder \fB.lz\fP).
+.PP
+Nach erfolgreicher Kompression oder Dekompression der \fIDatei\fP kopiert \fBxz\fP
+Eigentümer, Gruppe, Zugriffsrechte, Zugriffszeit und Änderungszeit aus der
+Ursprungs\-\fIDatei\fP in die Zieldatei. Sollte das Kopieren der Gruppe
+fehlschlagen, werden die Zugriffsrechte so angepasst, dass jenen Benutzern
+der Zugriff auf die Zieldatei verwehrt bleibt, die auch keinen Zugriff auf
+die Ursprungs\-\fIDatei\fP hatten. Das Kopieren anderer Metadaten wie
+Zugriffssteuerlisten oder erweiterter Attribute wird von \fBxz\fP noch nicht
+unterstützt.
+.PP
+Sobald die Zieldatei erfolgreich geschlossen wurde, wird die
+Ursprungs\-\fIDatei\fP entfernt. Dies wird durch die Option \fB\-\-keep\fP
+verhindert. Die Ursprungs\-\fIDatei\fP wird niemals entfernt, wenn die Ausgabe
+in die Standardausgabe geschrieben wird oder falls ein Fehler auftritt.
+.PP
+Durch Senden der Signale \fBSIGINFO\fP oder \fBSIGUSR1\fP an den \fBxz\fP\-Prozess
+werden Fortschrittsinformationen in den Fehlerkanal der Standardausgabe
+geleitet. Dies ist nur eingeschränkt hilfreich, wenn die
+Standardfehlerausgabe ein Terminal ist. Mittels \fB\-\-verbose\fP wird ein
+automatisch aktualisierter Fortschrittsanzeiger angezeigt.
+.
+.SS Speicherbedarf
+In Abhängigkeit von den gewählten Kompressionseinstellungen bewegt sich der
+Speicherverbrauch zwischen wenigen hundert Kilobyte und mehreren
+Gigabyte. Die Einstellungen bei der Kompression einer Datei bestimmen dabei
+den Speicherbedarf bei der Dekompression. Die Dekompression benötigt
+üblicherweise zwischen 5\ % und 20\ % des Speichers, der bei der Kompression
+der Datei erforderlich war. Beispielsweise benötigt die Dekompression einer
+Datei, die mit \fBxz \-9\fP komprimiert wurde, gegenwärtig etwa 65\ MiB
+Speicher. Es ist jedoch auch möglich, dass \fB.xz\fP\-Dateien mehrere Gigabyte
+an Speicher zur Dekompression erfordern.
+.PP
+Insbesondere für Benutzer älterer Systeme wird eventuell ein sehr großer
+Speicherbedarf ärgerlich sein. Um unangenehme Überraschungen zu vermeiden,
+verfügt \fBxz\fP über eine eingebaute Begrenzung des Speicherbedarfs, die
+allerdings in der Voreinstellung deaktiviert ist. Zwar verfügen einige
+Betriebssysteme über eingebaute Möglichkeiten zur prozessabhängigen
+Speicherbegrenzung, doch diese sind zu unflexibel (zum Beispiel kann
+\fBulimit\fP(1) beim Begrenzen des virtuellen Speichers \fBmmap\fP(2)
+beeinträchtigen).
+.PP
+Die Begrenzung des Speicherbedarfs kann mit der Befehlszeilenoption
+\fB\-\-memlimit=\fP\fIBegrenzung\fP aktiviert werden. Oft ist es jedoch bequemer,
+die Begrenzung durch Setzen der Umgebungsvariable \fBXZ_DEFAULTS\fP
+standardmäßig zu aktivieren, zum Beispiel
+\fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP. Die Begrenzungen können getrennt für
+Kompression und Dekompression mittels \fB\-\-memlimit\-compress=\fP\fIBegrenzung\fP
+und \fB\-\-memlimit\-decompress=\fP\fIBegrenzung\fP festgelegt werden. Die Verwendung
+einer solchen Option außerhalb der Variable \fBXZ_DEFAULTS\fP ist kaum
+sinnvoll, da \fBxz\fP in einer einzelnen Aktion nicht gleichzeitig Kompression
+und Dekompression ausführen kann und \fB\-\-memlimit=\fP\fIBegrenzung\fP (oder \fB\-M\fP
+\fIBegrenzung\fP) lässt sich einfacher in der Befehlszeile eingeben.
+.PP
+Wenn die angegebene Speicherbegrenzung bei der Dekompression überschritten
+wird, schlägt der Vorgang fehl und \fBxz\fP zeigt eine Fehlermeldung an. Wird
+die Begrenzung bei der Kompression überschritten, dann versucht \fBxz\fP die
+Einstellungen entsprechend anzupassen, außer wenn \fB\-\-format=raw\fP oder
+\fB\-\-no\-adjust\fP angegeben ist. Auf diese Weise schlägt die Aktion nicht fehl,
+es sei denn, die Begrenzung wurde sehr niedrig angesetzt. Die Anpassung der
+Einstellungen wird schrittweise vorgenommen, allerdings entsprechen die
+Schritte nicht den Voreinstellungen der Kompressionsstufen. Das bedeutet,
+wenn beispielsweise die Begrenzung nur geringfügig unter den Anforderungen
+für \fBxz \-9\fP liegt, werden auch die Einstellungen nur wenig angepasst und
+nicht vollständig herunter zu den Werten für \fBxz \-8\fP
+.
+.SS "Verkettung und Auffüllung von .xz\-Dateien"
+Es ist möglich, \fB.xz\fP\-Dateien direkt zu verketten. Solche Dateien werden
+von \fBxz\fP genauso dekomprimiert wie eine einzelne \fB.xz\fP\-Datei.
+.PP
+Es ist weiterhin möglich, eine Auffüllung zwischen den verketteten Teilen
+oder nach dem letzten Teil einzufügen. Die Auffüllung muss aus Null\-Bytes
+bestehen und deren Größe muss ein Vielfaches von vier Byte sein. Dies kann
+zum Beispiel dann vorteilhaft sein, wenn die \fB.xz\fP\-Datei auf einem
+Datenträger gespeichert wird, dessen Dateisystem die Dateigrößen in
+512\-Byte\-Blöcken speichert.
+.PP
+Verkettung und Auffüllung sind für \fB.lzma\fP\-Dateien oder Rohdatenströme
+nicht erlaubt.
+.
+.SH OPTIONEN
+.
+.SS "Ganzzahlige Suffixe und spezielle Werte"
+An den meisten Stellen, wo ein ganzzahliges Argument akzeptiert wird, kann
+ein optionales Suffix große Ganzzahlwerte einfacher darstellen. Zwischen
+Ganzzahl und dem Suffix dürfen sich keine Leerzeichen befinden.
+.TP 
+\fBKiB\fP
+multipliziert die Ganzzahl mit 1.024 (2^10). \fBKi\fP, \fBk\fP, \fBkB\fP, \fBK\fP und
+\fBKB\fP werden als Synonyme für \fBKiB\fP akzeptiert.
+.TP 
+\fBMiB\fP
+multipliziert die Ganzzahl mit 1.048.576 (2^20). \fBMi\fP, \fBm\fP, \fBM\fP und \fBMB\fP
+werden als Synonyme für \fBMiB\fP akzeptiert.
+.TP 
+\fBGiB\fP
+multipliziert die Ganzzahl mit 1.073.741.824 (2^30). \fBGi\fP, \fBg\fP, \fBG\fP und
+\fBGB\fP werden als Synonyme für \fBGiB\fP akzeptiert.
+.PP
+Der spezielle Wert \fBmax\fP kann dazu verwendet werden, um den von der
+jeweiligen Option akzeptierten maximalen Ganzzahlwert anzugeben.
+.
+.SS Aktionsmodus
+Falls mehrere Aktionsmodi angegeben sind, wird der zuletzt angegebene
+verwendet.
+.TP 
+\fB\-z\fP, \fB\-\-compress\fP
+Kompression. Dies ist der voreingestellte Aktionsmodus, sofern keiner

+werden keine Dateien erstellt oder entfernt.
+.TP 
+\fB\-l\fP, \fB\-\-list\fP
+gibt Informationen zu den komprimierten \fIDateien\fP aus. Es werden keine

+Standardeingabe oder anderen nicht durchsuchbaren Quellen lesen.
+.IP ""
+Die Liste zeigt in der Standardeinstellung grundlegende Informationen zu den
+\fIDateien\fP an, zeilenweise pro Datei. Detailliertere Informationen erhalten
+Sie mit der Option \fB\-\-verbose\fP. Wenn Sie diese Option zweimal angeben,
+werden noch ausführlichere Informationen ausgegeben. Das kann den Vorgang
+allerdings deutlich verlangsamen, da die Ermittlung der zusätzlichen
+Informationen zahlreiche Suchvorgänge erfordert. Die Breite der
+ausführlichen Ausgabe übersteigt 80 Zeichen, daher könnte die Weiterleitung
+in beispielsweise\& \fBless\ \-S\fP sinnvoll sein, falls das Terminal nicht
+breit genug ist.
+.IP ""
+Die exakte Ausgabe kann in verschiedenen \fBxz\fP\-Versionen und
+Spracheinstellungen unterschiedlich sein. Wenn eine maschinell auswertbare
+Ausgabe gewünscht ist, dann sollten Sie \fB\-\-robot \-\-list\fP verwenden.

+.SS Aktionsattribute
+.TP 
+\fB\-k\fP, \fB\-\-keep\fP
+verhindert das Löschen der Eingabedateien.
+.IP ""
+Seit der \fBxz\fP\-Version 5.2.6 wird die Kompression oder Dekompression auch
+dann ausgeführt, wenn die Eingabe ein symbolischer Link zu einer regulären
+Datei ist, mehr als einen harten Link hat oder das »setuid«\-, »setgid«\- oder
+»sticky«\-Bit gesetzt ist. Die genannten Bits werden nicht in die Zieldatei
+kopiert. In früheren Versionen geschah dies nur mit \fB\-\-force\fP.
+.TP 
+\fB\-f\fP, \fB\-\-force\fP
+Diese Option hat verschiedene Auswirkungen:

+.IP \(bu 3
+Wenn es zusammen mit \fB\-\-decompress\fP und \fB\-\-stdout\fP verwendet wird und
+\fBxz\fP den Typ der Quelldatei nicht ermitteln kann, wird die Quelldatei

+für Dateien, die nicht mit \fBxz\fP komprimiert wurden, wie \fBcat\fP(1) verwendet
+werden. Zukünftig könnte \fBxz\fP neue Dateikompressionsformate unterstützen,
+wodurch \fBxz\fP mehr Dateitypen dekomprimieren kann, anstatt sie unverändert
+in die Standardausgabe zu kopieren. Mit der Option \fB\-\-format=\fP\fIFormat\fP
+können Sie \fBxz\fP anweisen, nur ein einzelnes Dateiformat zu dekomprimieren.

+.TP 
+\fB\-c\fP, \fB\-\-stdout\fP, \fB\-\-to\-stdout\fP
+schreibt die komprimierten oder dekomprimierten Daten in die Standardausgabe

+.TP 
+\fB\-\-single\-stream\fP
+dekomprimiert nur den ersten \fB.xz\fP\-Datenstrom und ignoriert stillschweigend
+weitere Eingabedaten, die möglicherweise dem Datenstrom
+folgen. Normalerweise führt solcher anhängender Datenmüll dazu, dass \fBxz\fP
+eine Fehlermeldung ausgibt.
+.IP ""
+\fBxz\fP dekomprimiert niemals mehr als einen Datenstrom aus \fB.lzma\fP\-Dateien
+oder Rohdatenströmen, aber dennoch wird durch diese Option möglicherweise
+vorhandener Datenmüll nach der \fB.lzma\fP\-Datei oder dem Rohdatenstrom
+ignoriert.
+.IP ""
+Diese Option ist wirkungslos, wenn der Aktionsmodus nicht \fB\-\-decompress\fP
+oder \fB\-\-test\fP ist.
+.TP 
+\fB\-\-no\-sparse\fP
+verhindert die Erzeugung von Sparse\-Dateien. In der Voreinstellung versucht
+\fBxz\fP, bei der Dekompression in eine reguläre Datei eine Sparse\-Datei zu
+erzeugen, wenn die dekomprimierten Daten lange Abfolgen von binären Nullen
+enthalten. Dies funktioniert auch beim Schreiben in die Standardausgabe,
+sofern diese in eine reguläre Datei weitergeleitet wird und bestimmte
+Zusatzbedingungen erfüllt sind, die die Aktion absichern. Die Erzeugung von
+Sparse\-Dateien kann Plattenplatz sparen und beschleunigt die Dekompression
+durch Verringerung der Ein\-/Ausgaben der Platte.
+.TP 
+\fB\-S\fP \fI.suf\fP, \fB\-\-suffix=\fP\fI.suf\fP
+verwendet \fI.suf\fP bei der Dekompression anstelle von \fB.xz\fP oder \fB.lzma\fP
+als Suffix für die Zieldatei. Falls nicht in die Standardausgabe geschrieben
+wird und die Quelldatei bereits das Suffix \fI.suf\fP hat, wird eine Warnung

+\&\fI.suf\fP. Falls die Quelldatei das Suffix \fI.suf\fP hat, wird dieses entfernt
+und so der Name der Zieldatei abgeleitet.
+.IP ""
+Beim Komprimieren oder Dekomprimieren von Rohdatenströmen mit
+\fB\-\-format=raw\fP muss das Suffix stets angegeben werden, außer wenn die

+gelesen. Dateinamen müssen mit einem Zeilenumbruch beendet werden. Ein
+Bindestrich (\fB\-\fP) wird als regulärer Dateiname angesehen und nicht als

+dass beim Auswerten der Umgebungsvariablen nur Optionen berücksichtigt
+werden; alle Einträge, die keine Optionen sind, werden stillschweigend

+\fBXZ_DEFAULTS\fP
+Benutzerspezifische oder systemweite Standardoptionen. Typischerweise werden

+Variable \fBXZ_DEFAULTS\fP in Skripten niemals gesetzt oder außer Kraft gesetzt
+werden.
+.TP 
+\fBXZ_OPT\fP
+Dies dient der Übergabe von Optionen an \fBxz\fP, wenn es nicht möglich ist,

+.SH "KOMPATIBILITÄT ZU DEN LZMA\-UTILS"
+Die Befehlszeilensyntax von \fBxz\fP ist praktisch eine Obermenge der von
+\fBlzma\fP, \fBunlzma\fP und \fBlzcat\fP in den LZMA\-Utils der Versionen 4.32.x. In

+zu ersetzen, ohne vorhandene Skripte ändern zu müssen. Dennoch gibt es
+einige Inkompatibilitäten, die manchmal Probleme verursachen können.
+.
+.SS "Voreinstellungsstufen zur Kompression"
+Die Nummerierung der Voreinstellungsstufen der Kompression ist in \fBxz\fP und
+den LZMA\-Utils unterschiedlich. Der wichtigste Unterschied ist die Zuweisung
+der Wörterbuchgrößen zu den verschiedenen Voreinstellungsstufen. Die
+Wörterbuchgröße ist etwa gleich dem Speicherbedarf bei der Dekompression.

+.PP
+Die standardmäßige Voreinstellungsstufe in den LZMA\-Utils ist \fB\-7\fP, während

+MiB großes Wörterbuch.
+.
+.SS "Vor\- und Nachteile von .lzma\-Dateien als Datenströme"
+Die unkomprimierte Größe der Datei kann in den \fB.lzma\fP\-Headern gespeichert
+werden. Die LZMA\-Utils tun das beim Komprimieren gewöhnlicher Dateien. Als
+Alternative kann die unkomprimierte Größe als unbekannt markiert und eine
+Nutzdatenende\-Markierung (end\-of\-payload) verwendet werden, um anzugeben, wo
+der Dekompressor stoppen soll. Die LZMA\-Utils verwenden diese Methode, wenn
+die unkomprimierte Größe unbekannt ist, was beispielsweise in Pipes
+(Befehlsverkettungen) der Fall ist.
+.PP
+\fBxz\fP unterstützt die Dekompression von \fB.lzma\fP\-Dateien mit oder ohne
+Nutzdatenende\-Markierung, aber alle von \fBxz\fP erstellten \fB.lzma\fP\-Dateien
+verwenden diesen Nutzdatenende\-Markierung, wobei die unkomprimierte Größe in
+den \fB.lzma\fP\-Headern als unbekannt markiert wird. Das könnte in einigen
+unüblichen Situationen ein Problem sein. Zum Beispiel könnte ein
+\&\fB.lzma\fP\-Dekompressor in einem Gerät mit eingebettetem System nur mit
+Dateien funktionieren, deren unkomprimierte Größe bekannt ist. Falls Sie auf
+dieses Problem stoßen, müssen Sie die LZMA\-Utils oder das LZMA\-SDK
+verwenden, um \fB.lzma\fP\-Dateien mit bekannter unkomprimierter Größe zu
+erzeugen.
+.
+.SS "Nicht unterstützte .lzma\-Dateien"
+Das \fB.lzma\fP\-Format erlaubt \fIlc\fP\-Werte bis zu 8 und \fIlp\fP\-Werte bis zu
+4. Die LZMA\-Utils können Dateien mit beliebigem \fIlc\fP und \fIlp\fP
+dekomprimieren, aber erzeugen immer Dateien mit \fBlc=3\fP und \fBlp=0\fP. Das
+Erzeugen von Dateien mit anderem \fIlc\fP und \fIlp\fP ist mit \fBxz\fP und mit dem
+LZMA\-SDK möglich.
+.PP
+Die Implementation des LZMA\-Filters in liblzma setzt voraus, dass die Summe
+von \fIlc\fP und \fIlp\fP nicht größer als 4 ist. Daher können \fB.lzma\fP\-Dateien,
+welche diese Begrenzung überschreiten, mit \fBxz\fP nicht dekomprimiert werden.
+.PP
+Die LZMA\-Utils erzeugen nur \fB.lzma\fP\-Dateien mit einer Wörterbuchgröße von
+2^\fIn\fP (einer Zweierpotenz), aber akzeptieren Dateien mit einer beliebigen
+Wörterbuchgröße. Liblzma akzeptiert nur \fB.lzma\fP\-Dateien mit einer
+Wörterbuchgröße von 2^\fIn\fP oder 2^\fIn\fP + 2^(\fIn\fP\-1). Dies dient zum
+Verringern von Fehlalarmen beim Erkennen von \fB.lzma\fP\-Dateien.
+.PP
+Diese Einschränkungen sollten in der Praxis kein Problem sein, da praktisch
+alle \fB.lzma\fP\-Dateien mit Einstellungen komprimiert wurden, die Liblzma
+akzeptieren wird.
+.
+.SS "Angehängter Datenmüll"
+Bei der Dekompression ignorieren die LZMA\-Utils stillschweigend alles nach
+dem ersten \fB.lzma\fP\-Datenstrom. In den meisten Situationen ist das ein
+Fehler. Das bedeutet auch, dass die LZMA\-Utils die Dekompression verketteter
+\&\fB.lzma\fP\-Dateien nicht unterstützen.
+.PP
+Wenn nach dem ersten \fB.lzma\fP\-Datenstrom Daten verbleiben, erachtet \fBxz\fP
+die Datei als beschädigt, es sei denn, die Option \fB\-\-single\-stream\fP wurde
+verwendet. Dies könnte die Ausführung von Skripten beeinflussen, die davon
+ausgehen, dass angehängter Datenmüll ignoriert wird.
+.
+.SH ANMERKUNGEN
+.
+.SS "Die komprimierte Ausgabe kann variieren"
+Die exakte komprimierte Ausgabe, die aus der gleichen unkomprimierten
+Eingabedatei erzeugt wird, kann zwischen den Versionen der XZ\-Utils
+unterschiedlich sein, selbst wenn die Kompressionsoptionen identisch
+sind. Das kommt daher, weil der Kodierer verbessert worden sein könnte
+(hinsichtlich schnellerer oder besserer Kompression), ohne das Dateiformat
+zu beeinflussen. Die Ausgabe kann sogar zwischen verschiedenen Programmen
+der gleichen Version der XZ\-Utils variieren, wenn bei der Erstellung des
+Binärprogramms unterschiedliche Optionen verwendet wurden.
+.PP
+Sobald \fB\-\-rsyncable\fP implementiert wurde, bedeutet das, dass die sich
+ergebenden Dateien nicht notwendigerweise mit Rsync abgeglichen werden
+können, außer wenn die alte und neue Datei mit der gleichen \fBxz\fP\-Version
+erzeugt wurden. Das Problem kann beseitigt werden, wenn ein Teil der
+Encoder\-Implementierung eingefroren wird, um die mit Rsync abgleichbare
+Ausgabe über \fBxz\fP\-Versionsgrenzen hinweg stabil zu halten.
+.
+.SS "Eingebettete .xz\-Dekompressoren"
+Eingebettete \fB.xz\fP\-Dekompressor\-Implementierungen wie XZ Embedded
+unterstützen nicht unbedingt Dateien, die mit anderen Integritätsprüfungen
+(\fIPrüfung\fP\-Typen) als \fBnone\fP und \fBcrc32\fP erzeugt wurden. Da
+\fB\-\-check=crc64\fP die Voreinstellung ist, müssen Sie \fB\-\-check=none\fP oder
+\fB\-\-check=crc32\fP verwenden, wenn Sie Dateien für eingebettete Systeme
+erstellen.
+.PP
+Außerhalb eingebetteter Systeme unterstützen die Dekompressoren des
+\&\fB.xz\fP\-Formats alle \fIPrüfung\fP\-Typen oder sind mindestens in der Lage, die
+Datei zu dekomprimieren, ohne deren Integrität zu prüfen, wenn die bestimmte
+\fIPrüfung\fP nicht verfügbar ist.

+Wenn Sie wissen, dass eine Datei für eine gute Kompression ein etwas

+nur wenige Dateien von einem größeren Wörterbuch profitieren, wenn der
+KompCPU\-Wert niedrig bleibt. Der offensichtlichste Fall, in dem ein größeres
+Wörterbuch  sehr hilfreich sein kann, ist ein Archiv, das einander sehr
+ähnliche Dateien enthält, die jeweils wenigstens einige Megabyte groß
+sind. Das Wörterbuch muss dann deutlich größer sein als die einzelne Datei,
+damit LZMA2 den größtmöglichen Vorteil aus den Ähnlichkeiten der aufeinander
+folgenden Dateien zieht.
+.PP
+Wenn hoher Speicherbedarf für Kompression und Dekompression kein Problem ist
+und die zu komprimierende Datei mindestens einige Hundert Megabyte groß ist,

+Die Verwendung von \fB\-vv\fP (\fB\-\-verbose \-\-verbose\fP) wie im obigen Beispiel
+kann nützlich sein, um den Speicherbedarf für Kompressor und Dekompressor zu
+sehen. Denken Sie daran, dass ein Wörterbuch, das größer als die
+unkomprimierte Datei ist, Speicherverschwendung wäre. Daher ist der obige
+Befehl für kleine Dateien nicht sinnvoll.
+.PP
+Manchmal spielt die Kompressionszeit keine Rolle, aber der Speicherbedarf
+bei der Dekompression muss gering gehalten werden, zum Beispiel um die Datei
+auf eingebetteten Systemen dekomprimieren zu können. Der folgende Befehl
+verwendet \fB\-6e\fP (\fB\-6 \-\-extreme\fP) als Basis und setzt die Wörterbuchgröße
+auf nur 64\ KiB. Die sich ergebende Datei kann mit XZ Embedded (aus diesem

+BCJ\-Filter für x86 nicht als letzter Filter in der Filterkette gesetzt
+werden darf.

+Der Delta\-Filter zusammen mit LZMA2 kann bei Bitmap\-Bildern gute Ergebnisse
+liefern. Er sollte üblicherweise besser sein als PNG, welches zwar einige
+fortgeschrittene Filter als ein simples delta bietet, aber für die
+eigentliche Kompression »Deflate« verwendet.
+.PP
+Das Bild muss in einem unkomprimierten Format gespeichert werden, zum
+Beispiel als unkomprimiertes TIFF. Der Abstandsparameter des Delta\-Filters
+muss so gesetzt werden, dass er der Anzahl der Bytes pro Pixel im Bild
+entspricht. Zum Beispiel erfordert ein 24\-Bit\-RGB\-Bitmap \fBdist=3\fP, außerdem

+.SH BESCHREIBUNG
+\fBxzdec\fP ist ein auf Liblzma basierendes Nur\-Dekompressionswerkzeug für
+\&\fB.xz\fP\-Dateien (und \fBnur\fP für \fB.xz\fP\-Dateien). \fBxzdec\fP ist als direkter
+Ersatz für \fBxz\fP(1) in jenen Situationen konzipiert, wo ein Skript \fBxz \-\-decompress \-\-stdout\fP (und eventuelle einige andere höufig genutzte
+Optionen) zum Dekomprimieren von \fB.xz\fP\-Dateien. \fBlzmadec\fP ist weitgehend
+identisch zu \fBxzdec\fP, mit der Ausnahme, dass \fBlzmadec\fP \fB.lzma\fP\-Dateien
+anstelle von \fB.xz\fP\-Dateien unterstützt.
+.PP
+Um die Größe der ausführbaren Datei zu reduzieren, unterstützt \fBxzdec\fP
+weder Multithreading noch Lokalisierung. Außerdem liest es keine Optionen
+aus den Umgebungsvariablen \fBXZ_DEFAULTS\fP und \fBXZ_OPT\fP. \fBxzdec\fP
+unterstützt keine zwischenzeitlichen Fortschrittsinformationen: Das Senden
+von \fBSIGINFO\fP an \fBxzdec\fP hat keine Auswirkungen, jedoch beendet \fBSIGUSR1\fP
+den Prozess, anstatt Fortschrittsinformationen anzuzeigen.
+.SH OPTIONEN

+täglichen Gebrauch. \fBxzdec\fP oder \fBlzmadec\fP sind nur für Situationen
+gedacht, in denen ein kleinerer Dekompressor statt des voll ausgestatteten
+\fBxz\fP(1) wichtig ist.
+.PP
+\fBxzdec\fP und \fBlzmadec\fP sind nicht wirklich extrem klein. Die Größe kann
+durch Deaktivieren von Funktionen bei der Kompilierung von Liblzma weiter
+verringert werden, aber das sollte nicht für ausführbare Dateien getan
+werden, die in typischen Betriebssystemen ausgeliefert werden, außer in den
+Distributionen für eingebettete Systeme. Wenn Sie einen wirklich winzigen
+Dekompressor für \fB.xz\fP\-Dateien brauchen, sollten Sie stattdessen XZ
+Embedded in Erwägung ziehen.

+.PP
+Lors de l'écriture de scripts qui nécessitent de décompresser des fichiers,
+il est recommandé de toujours utiliser la commande \fBxz\fP avec les arguments
+appropriés (\fBxz \-d\fP ou \fBxz \-dc\fP) au lieu des commandes \fBunxz\fP et
+\fBxzcat\fP.
+.
+.SH DESCRIPTION
+\fBxz\fP is a general\-purpose data compression tool with command line syntax
+similar to \fBgzip\fP(1)  and \fBbzip2\fP(1).  The native file format is the
+\&\fB.xz\fP format, but the legacy \fB.lzma\fP format used by LZMA Utils and raw
+compressed streams with no container format headers are also supported.  In
+addition, decompression of the \fB.lz\fP format used by \fBlzip\fP is supported.
+.PP
+\fBxz\fP compresse ou décompresse chaque \fIfichier\fP en fonction du mode
+d'opération choisi. Si aucun \fIfichier\fP n'est donné ou \fIfichier\fP est \fB\-\fP,
+\fBxz\fP lit depuis l'entrée standard et écrit les données traitées sur la
+sortie standard. \fBxz\fP refusera (affichera une erreur et ignorera le
+\fIfichier\fP) d'écrire les données compressées sur la sortie standard si c'est
+un terminal. De même, \fBxz\fP refusera de lire des données compressées depuis
+l'entrée standard si c'est un terminal.
+.PP
+A moins que \fB\-\-sdout\fP ne soit indiqué, les \fIfichiers\fP autres que \fB\-\fP sont
+écrits dans un nouveau fichier dont le nom est dérivé du nom de \fIfichier\fP
+source\ :
+.IP \(bu 3
+Lors de la compression, le suffixe du format de fichier cible (\fB.xz\fP ou
+\&\fB.lzma\fP) est ajouté au nom de fichier source pour obtenir le nom de fichier
+cible.
+.IP \(bu 3
+When decompressing, the \fB.xz\fP, \fB.lzma\fP, or \fB.lz\fP suffix is removed from
+the filename to get the target filename.  \fBxz\fP also recognizes the suffixes
+\&\fB.txz\fP and \fB.tlz\fP, and replaces them with the \fB.tar\fP suffix.
+.PP
+Si le fichier cible existe déjà, une erreur est affichée et le \fIfichier\fP
+est ignoré.
+.PP
+Sauf s'il écrit dans la sortie standard, \fBxz\fP affichera un avertissement et
+ignorera le \fIfichier\fP dans les cas suivants\ :
+.IP \(bu 3
+\fIfichier\fP n'est pas un fichier normal. Les liens symboliques ne sont pas
+suivis et donc ne sont pas considérés comme des fichiers normaux.
+.IP \(bu 3
+\fIfichier\fP a plusieurs liens physiques.
+.IP \(bu 3
+\fIfichier\fP a un setuid, setgid ou sticky bit positionné.
+.IP \(bu 3
+Le mode d'opération est défini pour compresser et le \fIfichier\fP a déjà un
+suffixe du format de fichier cible (\fB.xz\fP ou \fB.txz\fP lors d'une compression
+en format \fB.xz\fP, et \fB.lzma\fP ou \fB.tlz\fP lors d'une compression en format
+\&\fB.lzma\fP).
+.IP \(bu 3
+The operation mode is set to decompress and the \fIfile\fP doesn't have a
+suffix of any of the supported file formats (\fB.xz\fP, \fB.txz\fP, \fB.lzma\fP,
+\&\fB.tlz\fP, or \fB.lz\fP).
+.PP
+Après la compression ou la décompression réussie du \fIfichier\fP, \fBxz\fP copie
+les permissions du propriétaire, du groupe, la date d'accès, et les
+modifications d'heure depuis le \fIfichier\fP source du fichier cible. Si la
+copie du groupe échoue, les permissions sont modifiées pour que le fichier
+cible ne soit pas accessible aux utilisateurs qui n'ont pas les droits
+d'accès au \fIfichier\fP source. \fBxz\fP ne prend actuellement pas en charge la
+copie d'autres métadonnées telles que les listes de contrôle d'accès ou les
+attributs étendus.
+.PP
+Once the target file has been successfully closed, the source \fIfile\fP is
+removed unless \fB\-\-keep\fP was specified.  The source \fIfile\fP is never removed
+if the output is written to standard output or if an error occurs.
+.PP
+Envoyer \fBSIGINFO\fP ou \fBSIGURSR1\fP au processus \fBxz\fP, lui fait afficher
+l'information de progression sur l'erreur standard. Cela a un intérêt limité
+car lorsque l'erreur standard est un terminal, utiliser \fB\-\-verbose\fP
+affichera automatiquement un indicateur de progression du processus.
+.
+.SS "Utilisation de la mémoire"
+L'utilisation de la mémoire par \fBxz\fP varie de quelques centaines de
+kilo\-octets à plusieurs gigaoctects en fonction des paramètres de
+compression. Les réglages utilisés lors de la compression d'un fichier
+déterminent les besoins en mémoire pour la décompression. Habituellement la
+décompression nécessite 5\% à 20\% de la quantité de mémoire utilisée pour
+la compression du fichier. Par exemple, décompresser un fichier créé avec
+\fBxz\-9\fP recquiert habituellement 65\ Mio de mémoire. Bien qu'il soit
+possible d'avoir des fichiers \fB.xz\fP nécessitant plusieurs gigaoctets de
+mémoire pour être décompressés.
+.PP
+Especially users of older systems may find the possibility of very large
+memory usage annoying.  To prevent uncomfortable surprises, \fBxz\fP has a
+built\-in memory usage limiter, which is disabled by default.  While some
+operating systems provide ways to limit the memory usage of processes,
+relying on it wasn't deemed to be flexible enough (for example, using
+\fBulimit\fP(1)  to limit virtual memory tends to cripple \fBmmap\fP(2)).
+.PP
+The memory usage limiter can be enabled with the command line option
+\fB\-\-memlimit=\fP\fIlimit\fP.  Often it is more convenient to enable the limiter
+by default by setting the environment variable \fBXZ_DEFAULTS\fP, for example,
+\fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP.  It is possible to set the limits
+separately for compression and decompression by using
+\fB\-\-memlimit\-compress=\fP\fIlimit\fP and \fB\-\-memlimit\-decompress=\fP\fIlimit\fP.
+Using these two options outside \fBXZ_DEFAULTS\fP is rarely useful because a
+single run of \fBxz\fP cannot do both compression and decompression and
+\fB\-\-memlimit=\fP\fIlimit\fP (or \fB\-M\fP \fIlimit\fP)  is shorter to type on the
+command line.
+.PP
+If the specified memory usage limit is exceeded when decompressing, \fBxz\fP
+will display an error and decompressing the file will fail.  If the limit is
+exceeded when compressing, \fBxz\fP will try to scale the settings down so that
+the limit is no longer exceeded (except when using \fB\-\-format=raw\fP or
+\fB\-\-no\-adjust\fP).  This way the operation won't fail unless the limit is very
+small.  The scaling of the settings is done in steps that don't match the
+compression level presets, for example, if the limit is only slightly less
+than the amount required for \fBxz \-9\fP, the settings will be scaled down only
+a little, not all the way down to \fBxz \-8\fP.
+.
+.SS "Concaténation et remplissage avec des fichiers .xz"
+Il est possible de concaténer les fichiers \fB.xz\fP tels quel. \fBxz\fP
+décompressera de tels fichiers comme s'ils étaient un unique fichier \fB.xz\fP.
+.PP
+It is possible to insert padding between the concatenated parts or after the
+last part.  The padding must consist of null bytes and the size of the
+padding must be a multiple of four bytes.  This can be useful, for example,
+if the \fB.xz\fP file is stored on a medium that measures file sizes in
+512\-byte blocks.
+.PP
+La concaténation et le remplissage ne sont pas autorisés avec les fichiers
+\&\fB.lzma\fP ou les flux bruts.
+.
+.SH OPTIONS
+.
+.SS "Suffixes entiers et valeurs spéciales."

+optionel permet d'indiquer facilement les grands entiers. Il ne doit pas y

+.SS "Fichiers .lzma en flux ou non"
+The uncompressed size of the file can be stored in the \fB.lzma\fP header.
+LZMA Utils does that when compressing regular files.  The alternative is to
+mark that uncompressed size is unknown and use end\-of\-payload marker to
+indicate where the decompressor should stop.  LZMA Utils uses this method
+when uncompressed size isn't known, which is the case, for example, in
+pipes.
+.PP
+\fBxz\fP prend en charge la décompression des fichiers \fB.lzma\fP avec ou sans
+marqueur de fin de charge utile, mais tous les fichiers \fB.lzma\fP créés par
+\fBxz\fP utiliseront un marqueur de fin de charge utile et ont la taille non
+compréssée marquée comme inconnue dans l'en\-tête \fB.lzma\fP. Cela peut être un
+problème dans quelques situations inhabituelles. Par exemple, un
+décompresseur \fB.lzma\fP dans un périphérique embarqué pourrait ne fonctionner
+qu'avec des fichiers dont la taille non comprimée est connue. Si vous vous
+heurtez à ce problème, vous devez utiliser les utilitaires LZMA ou LZMA SDK
+pour créer des fichiers \fB.lzma\fP avec une taille non compressée connue.
+.
+.SS "Fichiers .lzma non pris en charge"
+Le format \fB.lzma\fP autorise des valeurs \fIlc\fP jusqu'à\ 8, et des valeurs
+\fIlp\fP jusqu'à\ 4. Les outils LZMA peuvent décompresser des fichiers avec tous
+les \fIlc\fP et \fIlp\fP, mais créez toujours les fichiers avec \fBlc=3\fP et
+\fBlp=0\fP. Créer des fichiers avec d'autres valeurs \fIlc\fP et \fIlp\fP est
+possible avec \fBxz\fP et avec LZMA SDK.
+.PP
+L'implémentation du filtre LZMA1 dans liblzma nécessite que la somme de
+\fIlc\fP et \fIlp\fP soit inférieure ou égale à\ 4. Ainsi, les fichiers \fB.lzma\fP
+qui excèdent cette limitation ne peuvent pas être décompressés avec \fBxz\fP.
+.PP
+Les outils LZMA créent seulement des fichiers \fB.lzma\fP qui ont une taille de
+dictionnaire de 2^\fIn\fP (une puissance de\ 2) mais acceptent les fichiers avec
+toutes les tailles de dictionnaire. Libzlma n'accepte que les fichiers
+\&\fB.lzma\fP qui ont une taille dictionnaire de 2^\fIn\fP ou
+2^\fIn\fP\ +\ 2^(\fIn\fP\-1). Cela afin de diminuer les faux positifs lors de la
+détection des fichiers \fB.lzma\fP.
+.PP
+Ces limitations ne devraient pas poser problème en pratique, car
+pratiquement tous les fichiers \fB.lzma\fP ont été compressés avec des réglages
+que liblzma accepte.
+.
+.SS "Déchets excédentaires"
+Lors de la décompession, l'utilitaire LZMA ignore silencieusement tout ce
+qui est après le premier flux \fB.lzma\fP. Dans la majorité des situations,
+c'est un bogue. Cela veut dire aussi que les outils LZMA ne gèrent pas la
+décompression de fichiers \fB.lzma\fP concaténés.
+.PP
+S'il reste des données après le premier flux \fB.lzma\fP, \fBxz\fP considère que
+le fichier est corrompu sauf si \fB\-\-single\-stream\fP a été utilisé. Cela peut
+casser des scripts obscurs qui ont supposé que les déchets de fin de ligne
+sont ignorés.
+.
+.SH NOTES
+.
+.SS "La sortie compressée peut varier"
+La sortie compressée exacte produite par les même fichiers non compressés en
+entrée peut varier en fonction des différentes versions de l'utilitaire XZ,
+même si les options de compression sont identiques. En effet, il est
+possible d'améliorer l'encodeur (compression plus rapide ou meilleure) sans
+affecter le format du fichier. La sortie peut même varier entre différentes
+compilations de la même version d'utilitaire XZ, si des options de
+construction différentes sont utilisées.
+.PP
+Cela signifie qu'une fois que \fB\-\-rsyncable\fP a été implémenté, les fichiers
+résultants ne seront pas nécessairement synchronisables avec rsync à moins
+que les nouveaux et anciens fichiers n'aient été compressés avec la même
+version de xz. Ce problème peut être résolu si une partie de
+l'implémentation est gelée pour garantir la stabilité de la sortie rsyncable
+à travers les versions de xz.
+.
+.SS "Décompresseurs .xz embarqués"
+Les implémentations de décompresseur embarqué comme XZ\ Embedded ne gèrent
+pas nécessairement les fichiers créés avec d'autres types de \fIvérification\fP
+d'intégrité que \fBnone\fP et \fBCRC32\fP. Comme la valeur par défaut est

+.SH SYNOPSIS
+\fBxzdec\fP [\fIoption...\fP] [\fIfichier...\fP]
+.br
+\fBlzmadec\fP [\fIoption...\fP] [\fIfichier...\fP]
+.SH DESCRIPTION
+\fBxzdec\fP est un outil uniquement de décompression, basé sur liblzma pour les
+fichiers \fB.xz\fP (et seulement \fB.xz\fP). \fBxzdec\fP est destiné à remplacer
+\fBxz\fP(1) dans les situations les plus courantes où un script a été écrit
+pour utiliser \fBxz \-\-decompress \-\-stdout\fP (et possiblement quelques autres
+options courantes) pour décompresser des fichiers \fB.xz\fP. \fBlzmadec\fP est
+identique à \fBxzdec\fP, sauf que \fBlzmadec\fP prend en charge les fichiers
+\&\fB.lzma\fP au lieu des fichiers \fB.xz\fP.
+.PP
+Pour réduire la taille de l'exécutable, \fBxzdec\fP ne prend en charge ni le
+multithreading ni la localisation et ne lit pas les options des variables
+d'environnement \fBXZ_DEFAULTS\fP et \fBXZ_OPT\fP. \fBxzdec\fP ne gère pas
+l'affichage d'information sur la progression du traitement\ : envoyer
+\fBSIGINFO\fP à \fBxzdec\fP ne fait rien, mais envoyer \fBSIGUSR1\fP termine le
+processus au lieu d'afficher de l'information sur la progression.

+.SH NOTES
+Utilisez \fBxz\fP(1) au lieu de \fBxzdec\fP ou \fBlzmadec\fP pour un usage normal de
+tous les jours. \fBxzdec\fP ou \fBlzmadec\fP ne sont utiles que pour les
+situations où il est important d'avoir un plus petit décompresseur que le
+\fBxz\fP(1) complet.
+.PP
+\fBxzdec\fP et \fBlzmadec\fP ne sont en fait pas vraiment si petits. La taille
+peut être encore réduite en abandonnant des fonctionnalités de liblzma au
+moment de la compilation, mais cela ne devrait pas être fait pour des

+.
+.SH 설명
+\fBxz\fP는 \fBgzip\fP(1)  과 \fBbzip2\fP(1)  과 비슷한 명령행 문법을 지닌 범용 데이터 압축 도구입니다.  자체 파일
+형식은 \fB.xz\fP 형식이나, LZMA 유틸리티에서 사용하는 예전 \fB.lzma\fP 형식과 형식 헤더가 없는 RAW 압축 스트림도
+지원합니다.  게다가, \fBlzip\fP에서 활용하는 \fB.lz\fP 형식 압축 해제도 지원합니다.
+.PP
+각 \fI파일\fP 에 대한 \fBxz\fP 압축 또는 압축 해제는 선택 동작 모드에 따릅니다.  \fI<파일>\fP 값이 주어졌거나
+\fI<파일>\fP 값이 \fB\-\fP이면, \fBxz\fP 명령에서 표준 입력을 읽고 처리한 데이터를 표준 출력에 기록합니다.
+\fBxz\fP 에서는 터미널에서 활용할 경우 압축 데이터를 표준 압축으로 기록하는 동작을 거절(오류를 출력하고 \fI<파일>\fP을
+건너뜀)합니다.  이와 비슷하게, \fBxz\fP 유틸리티를 터미널에서 실행하면 표준 입력의 압축 데이터 읽기를 거절합니다.
+.PP
+\fB\-\-stdout\fP 을 지정하지 않는 한, \fB\-\fP가 아닌 \fI<파일>\fP을 원본 \fI<파일>\fP 이름에서
+가져온 새 파일 이름으로 기록합니다:
+.IP \(bu 3
+압축할 때, 대상 파일 형식의 접미사(\fB.xz\fP or \fB.lzma\fP)  는 원본 파일 이름 뒤에 붙어 대상 파일이름이 됩니다.
+.IP \(bu 3
+압축 해제할 때, \fB.xz\fP, \fB.lzma\fP, \fB.lz\fP 접미사를 파일 이름에서 제거하고 대상 파일 이름을 알아냅니다.
+\fBxz\fP에서는 \fB.txz\fP, \fB.tlz\fP 접미사도 인식하며, \fB.tar\fP 접미사로 치환합니다.
+.PP
+대상 파일이 이미 있으면, 오류를 나타내고 \fI<파일>\fP을 건너뜁니다.
+.PP
+표준 출력으로 기록하기 전에는, \fBxz\fP는 경고를 나타내며, 다음 조건에 만족할 경우 \fI<파일>\fP을 건너뜁니다:
+.IP \(bu 3
+\fI<파일>\fP이 일반 파일이 아닐 때.  심볼릭 링크는 따라가지 않기에, 일반 파일로 간주하지 않습니다.
+.IP \(bu 3
+\fI<파일>\fP이 하나 이상의 하드 링크일 떄.

+\fI<파일>\fP에 setuid, setgid, 끈적이 비트 집합이 붙어있을 떄.
+.IP \(bu 3
+동작 모드를 압축으로 설정하고, \fI<파일>\fP은 대상 파일 형식의 접미사를 이미 붙였을 때(\fB.xz\fP 형식으로 압축하면
+\&\fB.xz\fP 또는 \fB.txz\fP, \fB.lzma\fP 형식으로 압축하면 \fB.lzma\fP 또는 \fB.tlz\fP).

+동작 모드를 압축 해제로 설정하고, \fI<파일>\fP에 지원 파일 형식 접미사(\fB.xz\fP, \fB.txz\fP, \fB.lzma\fP,
+\&\fB.tlz\fP, \fB.lz\fP)를 붙이지 않았을 때.
+.PP
+\fI<파일>\fP 의 압축 또는 압축 해제를 성공하고 나면, \fBxz\fP는 소유자, 소유그룹, 권한, 접근 시각, 수정 시각
+정보를 원본 \fI<파일>\fP에서 대상 파일로 그대로 복사합니다.  그룹 정보 복사에 실패하면, 권한을 수정하여 원본
+\fI<파일>\fP에 접근 권한이 없는 사용자가 대상 파일로 접근하지 못하게 합니다.  \fBxz\fP는 아직 접근 제어 목록이나
+확장 속성 등의 기타 메타데이터를 복사하는 기능은 지원하지 않습니다.
+.PP
+대상 파일을 온전히 닫고 나면, \fB\-\-keep\fP 옵션을 지원하지 않았을 경우 원본 \fI<파일>\fP을 제거합니다.  원본
+\fI<파일>\fP은 출력을 표준 출력으로 기록했거나 오류가 발생했을 경우 제거하지 않습니다.
+.PP
+\fBxz\fP 프로세스에 \fBSIGINFO\fP 시그널 또는 \fBSIGUSR1\fP 시그널을 보내면 표준 출력으로 진행 정보를 출력합니다.  표준
+오류가 터미널일 경우일 경우에만 제한하며 \fB\-\-verbose\fP 옵션을 지정하면 진행 표시줄을 자동으로 나타냅니다.
+.
+.SS "메모리 사용"
+\fBxz\fP 메모리 사용은 수백 킬로바이트로 시작하여 수 기가바이트까지 압축 설정에 따라 다릅니다.  압축 해제 프로그램이 필요로 하는
+메모리 공간을 결정하는 파일 압축시에 설정 값을 활용합니다.  보통 압축 해제 프로그램은 파일을 만들 때, 압축 프로그램 메모리 사용량의
+5% 에서 20% 정도 필요합니다.  예를 들면, \fBxz \-9\fP로 압축한 파일 압축 해제시 현재 65MiB 메모리 용량이 필요합니다.
+여전하게도, 압축 해제시 수 기가 바이트의 메모리가 필요한 \fB.xz\fP 파일에도 가능한 이야기입니다.
+.PP
+특히 이전 시스템 사용자의 경우 메모리 사용량이 엄청나게 늘어나는 점에 짜증이 날 수 있습니다.  이런 불편한 상황을 피하기 위해,
+\fBxz\fP에 기본적으로 비활성 상태인 내장 메모리 사용 제한 기능을 넣었습니다.  일부 운영체제에서 처리 중 메모리 사용을 제한하는
+수단을 제공하긴 하지만, 여기에 의지하기에는 충분히 유연하지 않습니다(예를 들면, \fBulimit\fP(1)을 사용하면 가상 메모리를
+제한하여  \fBmmap\fP(2)을 먹통으로 만듭니다).
+.PP
+메모리 사용 제한 기능은 \fB\-\-memlimit=\fP\fI<제한용량>\fP 명령행 옵션으로 사용할 수 있습니다.  종종
+\fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP와 같이 \fBXZ_DEFAULTS\fP 환경 변수를 설정하여 제한 기능을 켜는게 더
+편합니다.  \fB\-\-memlimit\-compress=\fP\fI<제한용량>\fP 옵션과
+\fB\-\-memlimit\-decompress=\fP\fI<제한용량>\fP 옵션을 활용하여 압축 및 압축 해제시 별도로 한계 값을
+설정할 수 있습니다.  이 두 가지 옵션의 \fBXZ_DEFAULTS\fP 환경 변수 밖에서의 사용은, \fBxz\fP를 단일 실행할 때 압축 및
+압축 해제 동작을 동시에 수행하지 않으며, 앞서 언급한 두가지 옵션을 명령행에 입력하기에는
+\fB\-\-memlimit=\fP\fI<제한용량>\fP(또는 \fB\-M\fP \fI<제한용량>\fP)이 더 짧기 때문에 별로 쓸모가
+없습니다.
+.PP
+압축 해제시 메모리 사용 제한 지정 한계를 초과하면, \fBxz\fP 유틸리티에서 오류를 나타내며 파일 압축 해제는 실패합니다.  압축을
+실행할 때 사용 제한 지정 한계를 넘어서면 \fBxz\fP에서는 설정 값을 줄여서 어쨌든 한계를 넘지 못하게
+합니다(\fB\-\-format=raw\fP 옵션 또는 \fB\-\-no\-adjust\fP 옵션 사용시 제외).  설정 한계 값이 엄청 작지 않은 이상 이
+방식대로 처리하면 어쨌든 실패하지 않습니다.  설정 값조정은 압축 래벨 사전 설정과 일치하지 않을 때 단계적으로 진행하는데, 이를테면,
+\fBxz \-9\fP 명령 수행에 필요한 양보다 한계 값이 약간 작으면, 설정 값을 \fBxz \-8\fP에 못미치게 약간 줄여서 진행합니다.
+.
+.SS ".xz 파일 결합 및 패딩"

+있습니다.  파일 형식에 영향을 주지 않고 인코더 그 자체를 개선(더 빠르게 하거나 더 나은 압축율로)하기 때문입니다.  XZ 유틸리티

+.PP
+Ao escrever scripts que precisam descompactar arquivos, é recomendável
+sempre usar o nome \fBxz\fP com os argumentos apropriados (\fBxz \-d\fP ou \fBxz \-dc\fP) em vez dos nomes \fBunxz\fP e \fBxzcat\fP.
+.
+.SH DESCRIÇÃO
+\fBxz\fP é uma ferramenta de compactação de dados de uso geral com sintaxe de
+linha de comando semelhante ao \fBgzip\fP(1) e ao \fBbzip2\fP(1). O formato de
+arquivo nativo é o formato \fB.xz\fP, mas o formato legado \fB.lzma\fP usado por
+LZMA Utils e fluxos compactados brutos sem cabeçalhos de formato de
+contêiner também são suportados. Além disso, a descompactação do formato
+\&\fB.lz\fP usado por \fBlzip\fP é suportada.
+.PP
+\fBxz\fP compacta ou descompacta cada \fIarquivo\fP de acordo com o modo de
+operação selecionado. Se nenhum \fIarquivo\fP for fornecido ou \fIarquivo\fP for
+\fB\-\fP, \fBxz\fP lê da entrada padrão e grava os dados processados na saída
+padrão. \fBxz\fP recusará (exibirá um erro e ignorará o \fIarquivo\fP) para gravar
+dados compactados na saída padrão se for um terminal. Da mesma forma, \fBxz\fP
+se recusará a ler dados compactados da entrada padrão se for um terminal.
+.PP
+A menos que \fB\-\-stdout\fP seja especificado, \fIarquivos\fP diferentes de \fB\-\fP
+são gravados em um novo arquivo cujo nome é derivado do nome \fIarquivo\fP de
+origem:
+.IP \(bu 3
+Ao compactar, o sufixo do formato de arquivo de destino (\fB.xz\fP ou \fB.lzma\fP)
+é anexado ao nome do arquivo de origem para obter o nome do arquivo de
+destino.
+.IP \(bu 3
+Ao descompactar, o sufixo \fB.xz\fP, \fB.lzma\fP ou \fB.lz\fP é removido do nome do
+arquivo para obter o nome do arquivo de destino. \fBxz\fP também reconhece os
+sufixos \fB.txz\fP e \fB.tlz\fP e os substitui pelo sufixo \fB.tar\fP.
+.PP
+Se o arquivo de destino já existir, um erro será exibido e \fIarquivo\fP será
+ignorado.
+.PP
+A menos que grave na saída padrão, \fBxz\fP exibirá um aviso e pulará o
+\fIarquivo\fP se qualquer um dos seguintes se aplicar:
+.IP \(bu 3
+\fIArquivo\fP não é um arquivo normal. Links simbólicos não são seguidos e,
+portanto, não são considerados arquivos comuns.
+.IP \(bu 3
+\fIArquivo\fP tem mais de um link físico.
+.IP \(bu 3
+\fIFile\fP tem setuid, setgid ou sticky bit definido.
+.IP \(bu 3
+O modo de operação está definido para compactar e o \fIarquivo\fP já possui um
+sufixo do formato de arquivo de destino (\fB.xz\fP ou \fB.txz\fP ao compactar para
+o formato \fB.xz\fP e \fB.lzma \fP ou \fB.tlz\fP ao compactar para o formato
+\&\fB.lzma\fP).
+.IP \(bu 3
+O modo de operação está definido para descompactar e o \fIarquivo\fP não possui
+um sufixo de nenhum dos formatos de arquivo suportados (\fB.xz\fP, \fB.txz\fP,
+\&\fB.lzma\fP, \fB.tlz\fP , ou \fB.lz\fP).
+.PP
+Depois de compactar ou descompactar com êxito o \fIarquivo\fP, o \fBxz\fP copia o
+dono, grupo, permissões, horário de acesso e horário de modificação do
+\fIarquivo\fP de origem para o arquivo de destino. Se a cópia do grupo falhar,
+as permissões serão modificadas para que o arquivo de destino não se torne
+acessível a usuários que não têm permissão para acessar o \fIarquivo\fP de
+origem. \fBxz\fP ainda não oferece suporte à cópia de outros metadados, como
+listas de controle de acesso ou atributos estendidos.
+.PP
+Depois que o arquivo de destino for fechado com êxito, o \fIarquivo\fP de
+origem será removido, a menos que \fB\-\-keep\fP tenha sido especificado. O
+\fIarquivo\fP de origem nunca é removido se a saída for gravada na saída padrão
+ou se ocorrer um erro.
+.PP
+O envio de \fBSIGINFO\fP ou \fBSIGUSR1\fP para o processo do \fBxz\fP faz com que ele
+imprima informações de andamento para erro padrão. Isso tem uso limitado,
+pois quando o erro padrão é um terminal, usar \fB\-\-verbose\fP exibirá um
+indicador de progresso de atualização automática.
+.
+.SS "Uso de memória"
+O uso de memória de \fBxz\fP varia de algumas centenas de kilobytes a vários
+gigabytes, dependendo das configurações de compactação. As configurações
+usadas ao compactar um arquivo determinam os requisitos de memória do
+descompactador. Normalmente, o descompactador precisa de 5\ % a 20\ % da
+quantidade de memória que o compactador precisou ao criar o arquivo. Por
+exemplo, descompactar um arquivo criado com \fBxz \-9\fP atualmente requer 65\ MiB de memória. Ainda assim, é possível ter arquivos \fB.xz\fP que requerem
+vários gigabytes de memória para descompactar.
+.PP
+Especialmente os usuários de sistemas mais antigos podem achar irritante a
+possibilidade de uso de memória muito grande. Para evitar surpresas
+desconfortáveis, o \fBxz\fP possui um limitador de uso de memória embutido, que
+está desabilitado por padrão. Embora alguns sistemas operacionais forneçam
+maneiras de limitar o uso de memória dos processos, confiar nele não foi
+considerado flexível o suficiente (por exemplo, usar \fBulimit\fP(1) para
+limitar a memória virtual tende a prejudicar \fBmmap\fP(2)).
+.PP
+O limitador de uso de memória pode ser ativado com a opção de linha de
+comando \fB\-\-memlimit=\fP\fIlimite\fP. Geralmente é mais conveniente habilitar o
+limitador por padrão definindo a variável de ambiente \fBXZ_DEFAULTS\fP, por
+exemplo, \fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP. É possível definir os limites
+separadamente para compactação e descompactação usando
+\fB\-\-memlimit\-compress=\fP\fIlimite\fP e \fB\-\-memlimit\-decompress=\fP\fIlimite\fP. Usar
+essas duas opções fora de \fBXZ_DEFAULTS\fP raramente é útil porque uma única
+execução de \fBxz\fP não pode fazer compactação e descompactação e
+\fB\-\-memlimit=\fP\fIlimite\fP (ou \fB\-M\fP \fIlimite\fP ) é mais curto para digitar na
+linha de comando.
+.PP
+Se o limite de uso de memória especificado for excedido durante a
+descompactação, \fBxz\fP exibirá um erro e a descompactação do arquivo
+falhará. Se o limite for excedido durante a compactação, \fBxz\fP tentará
+reduzir as configurações para que o limite não seja mais excedido (exceto ao
+usar \fB\-\-format=raw\fP ou \fB\-\-no\-adjust\fP). Dessa forma, a operação não
+falhará, a menos que o limite seja muito pequeno. A escala das configurações
+é feita em etapas que não correspondem às predefinições do nível de
+compactação, por exemplo, se o limite for apenas um pouco menor que o valor
+necessário para \fBxz \-9\fP, as configurações serão reduzidas apenas um pouco ,
+não até \fBxz \-8\fP.
+.
+.SS "Concatenação e preenchimento com arquivos .xz"
+É possível concatenar arquivos \fB.xz\fP como estão. \fBxz\fP irá descompactar
+tais arquivos como se fossem um único arquivo \fB.xz\fP.
+.PP
+É possível inserir preenchimento entre as partes concatenadas ou após a
+última parte. O preenchimento deve consistir em bytes nulos e o tamanho do
+preenchimento deve ser um múltiplo de quatro bytes. Isso pode ser útil, por
+exemplo, se o arquivo \fB.xz\fP for armazenado em uma mídia que mede tamanhos
+de arquivo em blocos de 512 bytes.
+.PP
+Concatenação e preenchimento não são permitidos com arquivos \fB.lzma\fP ou
+fluxos brutos.
+.
+.SH OPÇÕES
+.
+.SS "Sufixos inteiros e valores especiais"
+Na maioria dos lugares onde um argumento inteiro é esperado, um sufixo
+opcional é suportado para indicar facilmente números inteiros grandes. Não
+deve haver espaço entre o número inteiro e o sufixo.
+.TP 
+\fBKiB\fP
+Multiplica o inteiro por 1.024 (2^10). \fBKi\fP, \fBk\fP, \fBkB\fP, \fBK\fP e \fBKB\fP são
+aceitos como sinônimos de \fBKiB\fP.
+.TP 
+\fBMiB\fP
+Multiplica o número inteiro por 1.048.576 (2^20). \fBMi\fP, \fBm\fP, \fBM\fP e \fBMB\fP
+são aceitos como sinônimos de \fBMiB\fP.
+.TP 
+\fBGiB\fP
+Multiplica o número inteiro por 1.073.741.824 (2^30). \fBGi\fP, \fBg\fP, \fBG\fP e
+\fBGB\fP são aceitos como sinônimos de \fBGiB\fP.
+.PP
+O valor especial \fBmax\fP pode ser usado para indicar o valor inteiro máximo
+suportado pela opção.

+.SS "Modo de operação"
+Se várias opções de modo de operação forem dadas, a última entrará em vigor.
+.TP 
+\fB\-z\fP, \fB\-\-compress\fP
+Compacta. Este é o modo de operação padrão quando nenhuma opção de modo de

+.IP ""
+A listagem padrão mostra informações básicas sobre \fIarquivos\fP, um arquivo

+\fB\-\-verbose\fP. Para obter ainda mais informações, use \fB\-\-verbose\fP duas
+vezes, mas observe que isso pode ser lento, porque obter todas as
+informações extras requer muitas buscas. A largura da saída detalhada excede
+80 caracteres, portanto, canalizar a saída para, por exemplo, \fBless\ \-S\fP
+pode ser conveniente se o terminal não tiver largura o suficiente.
+.IP ""
+A saída exata pode variar entre versões \fBxz\fP e localidades diferentes. Para
+saída legível por máquina, \fB\-\-robot \-\-list\fP deve ser usado.

+.SS "Modificadores de operação"
+.TP 
+\fB\-k\fP, \fB\-\-keep\fP
+Não exclui os arquivos de entrada.
+.IP ""
+Desde \fBxz\fP 5.2.6, esta opção também faz \fBxz\fP compactar ou descompactar

+.IP \(bu 3
+Quando usado com \fB\-\-decompress\fP \fB\-\-stdout\fP e \fBxz\fP não consegue reconhecer
+o tipo do arquivo de origem, copia o arquivo de origem como está na saída

+arquivos que não foram compactados com \fBxz\fP. Observe que, no futuro, o
+\fBxz\fP pode oferecer suporte a novos formatos de arquivo compactado, o que
+pode fazer com que o \fBxz\fP descompacte mais tipos de arquivos em vez de
+copiá\-los como na saída padrão. \fB\-\-format=\fP\fIformato\fP pode ser usado para
+restringir \fBxz\fP para descompactar apenas um único formato de arquivo.
+.RE
+.TP 
+\fB\-c\fP, \fB\-\-stdout\fP, \fB\-\-to\-stdout\fP

+restante posterior sem uso faz com que \fBxz\fP exiba um erro.
+.IP ""
+\fBxz\fP nunca descompacta mais de um fluxo de arquivos \fB.lzma\fP ou fluxos

+.TP 
+\fB\-\-no\-sparse\fP
+Desativa a criação de arquivos esparsos. Por padrão, ao descompactar em um
+arquivo normal, \fBxz\fP tenta tornar o arquivo esparso se os dados
+descompactados contiverem longas sequências de zeros binários. Ele também
+funciona ao gravar na saída padrão, desde que a saída padrão esteja
+conectada a um arquivo normal e certas condições adicionais sejam atendidas
+para torná\-la segura. A criação de arquivos esparsos pode economizar espaço
+em disco e acelerar a descompactação, reduzindo a quantidade de E/S do

+.
+.SS "Arquivos .lzma em um fluxo versus sem ser em um fluxo"
+O tamanho descompactado do arquivo pode ser armazenado no cabeçalho de
+\&\fB.lzma\fP. O LZMA Utils faz isso ao compactar arquivos comuns. A alternativa
+é marcar que o tamanho não compactado é desconhecido e usar o marcador de
+fim de carga útil para indicar onde o descompactador deve parar. O LZMA
+Utils usa este método quando o tamanho não compactado não é conhecido, como
+é o caso, por exemplo, de encadeamentos (pipes).
+.PP
+\fBxz\fP oferece suporte à descompactação de arquivos \fB.lzma\fP com ou sem
+marcador de fim de carga útil, mas todos os arquivos \fB.lzma\fP criados por
+\fBxz\fP usarão marcador de fim de carga útil e terão o tamanho descompactado
+marcado como desconhecido no cabeçalho de \fB.lzma\fP. Isso pode ser um
+problema em algumas situações incomuns. Por exemplo, um descompactador de
+\&\fB.lzma\fP em um dispositivo embarcado pode funcionar apenas com arquivos que
+tenham tamanho descompactado conhecido. Se você encontrar esse problema,
+precisará usar o LZMA Utils ou o LZMA SDK para criar arquivos \fB.lzma\fP com
+tamanho descompactado conhecido.
+.
+.SS "Arquivos .lzma não suportados"
+O formato \fB.lzma\fP permite valores \fIlc\fP até 8 e valores \fIlp\fP até 4. LZMA
+Utils pode descompactar arquivos com qualquer \fIlc\fP e \fIlp\fP, mas sempre cria
+arquivos com \fBlc=3\fP e \fBlp=0\fP. Criar arquivos com outros \fIlc\fP e \fIlp\fP é
+possível com \fBxz\fP e com LZMA SDK.
+.PP
+A implementação do filtro LZMA1 em liblzma requer que a soma de \fIlc\fP e
+\fIlp\fP não exceda 4. Assim, arquivos \fB.lzma\fP, que excedam esta limitação,
+não podem ser descompactados com \fBxz\fP.
+.PP
+LZMA Utils cria apenas arquivos \fB.lzma\fP que possuem um tamanho de
+dicionário de 2^\fIn\fP (uma potência de 2), mas aceita arquivos com qualquer
+tamanho de dicionário. liblzma aceita apenas arquivos \fB.lzma\fP que tenham um
+tamanho de dicionário de 2^\fIn\fP ou 2^\fIn\fP + 2^(\fIn\fP\-1). Isso é para diminuir
+os falsos positivos ao detectar arquivos \fB.lzma\fP.
+.PP
+Essas limitações não devem ser um problema na prática, já que praticamente
+todos os arquivos \fB.lzma\fP foram compactados com configurações que o liblzma
+aceitará.
+.
+.SS "Lixo à direita"
+Ao descompactar, o LZMA Utils silenciosamente ignora tudo após o primeiro
+fluxo \fB.lzma\fP. Na maioria das situações, isso é um bug. Isso também
+significa que o LZMA Utils não oferece suporte a descompactação de arquivos
+\&\fB.lzma\fP concatenados.
+.PP
+Se houver dados restantes após o primeiro fluxo de \fB.lzma\fP, \fBxz\fP considera
+o arquivo corrompido, a menos que \fB\-\-single\-stream\fP tenha sido usado. Isso
+pode quebrar scripts obscuros que presumiram que o lixo à direita é
+ignorado.
+.
+.SH NOTAS
+.
+.SS "A saída compactada pode variar"
+A saída compactada exata produzida a partir do mesmo arquivo de entrada não
+compactado pode variar entre as versões do XZ Utils, mesmo se as opções de
+compactação forem idênticas. Isso ocorre porque o codificador pode ser
+aprimorado (compactação mais rápida ou melhor) sem afetar o formato do
+arquivo. A saída pode variar mesmo entre diferentes compilações da mesma
+versão do XZ Utils, se diferentes opções de compilação forem usadas.
+.PP
+A informação acima significa que, uma vez que \fB\-\-rsyncable\fP tenha sido
+implementado, os arquivos resultantes não serão necessariamente
+"rsyncáveis", a menos que os arquivos antigos e novos tenham sido
+compactados com a mesma versão xz. Esse problema pode ser corrigido se uma
+parte da implementação do codificador for congelada para manter a saída de
+rsyncable estável nas versões do xz.
+.
+.SS "Descompactadores .xz embarcados"
+As implementações do descompactador \fB.xz\fP embarcados, como o XZ Embedded,
+não oferecem necessariamente suporte a arquivos criados com tipos de
+\fIverificações\fP de integridade diferentes de \fBnone\fP e \fBcrc32\fP. Como o
+padrão é \fB\-\-check=crc64\fP, você deve usar \fB\-\-check=none\fP ou
+\fB\-\-check=crc32\fP ao criar arquivos para sistemas embarcados.
+.PP
+Fora dos sistemas embarcados, todos os descompactadores de formato \fB.xz\fP
+oferecem suporte a todos os tipos de \fIverificação\fP ou, pelo menos, são
+capazes de descompactar o arquivo sem verificar a verificação de integridade

+.
+.SH DESCRIERE
+\fBxz\fP este un instrument de comprimare a datelor de uz general cu sintaxă de
+linie de comandă similară cu \fBgzip\fP(1) și \fBbzip2\fP(1).  Formatul de fișier
+nativ este formatul \fB.xz\fP, dar formatul vechi \fB.lzma\fP folosit de LZMA
+Utils și fluxurile comprimate brute fără anteturi de format container sunt
+de asemenea acceptate.  În plus, este acceptată decomprimarea formatului
+\&\fB.lz\fP folosit de \fBlzip\fP.
+.PP
+\fBxz\fP comprimă sau decomprimă fiecare \fIfișier\fP în funcție de modul de
+operare selectat.  Dacă nu sunt date \fIfișiere\fP sau \fIfișier\fP este \fB\-\fP,
+\fBxz\fP citește de la intrarea standard și scrie datele procesate la ieșirea
+standard.  \fBxz\fP va refuza (afișează o eroare și omite \fIfișier\fP) să scrie
+date comprimate la ieșirea standard dacă este un terminal.  În mod similar,
+\fBxz\fP va refuza să citească datele comprimate de la intrarea standard dacă
+este un terminal.
+.PP
+Cu excepția cazului în care este specificată opțiunea \fB\-\-stdout\fP,
+\fIfișierele\fP altele decât \fB\-\fP sunt scrise într\-un fișier nou al cărui nume
+este derivat din numele \fIfișierului\fP sursă:
+.IP \(bu 3
+La comprimare, sufixul formatului de fișier țintă (\fB.xz\fP sau \fB.lzma\fP)
+este atașat la numele fișierului sursă pentru a se obține numele fișierului
+țintă.
+.IP \(bu 3
+La decomprimare, sufixul \fB.xz\fP, \fB.lzma\fP sau \fB.lz\fP este eliminat din
+numele fișierului pentru a se obține numele fișierului țintă.  \fBxz\fP
+recunoaște și sufixele \fB.txz\fP și \fB.tlz\fP și le înlocuiește cu sufixul
+\&\fB.tar\fP.
+.PP
+Dacă fișierul țintă există deja, este afișată o eroare și \fIfișier\fP este
+omis.
+.PP
+Cu excepția cazului în care scrie la ieșirea standard, \fBxz\fP va afișa un
+avertisment și va omite \fIfișier\fPul dacă se aplică oricare dintre
+următoarele:
+.IP \(bu 3
+\fIFișierul\fP nu este un fișier obișnuit.  Legăturile simbolice nu sunt urmate
+și, prin urmare, nu sunt considerate fișiere obișnuite.
+.IP \(bu 3
+\fIFișierul\fP are mai mult de o legătură dură.
+.IP \(bu 3
+\fIFișierul\fP are activat bitul «setuid», «setgid» sau cel lipicios(sticky).
+.IP \(bu 3
+Modul de operare este stabilit la comprimare și \fIfișier\fP are deja un sufix
+al formatului de fișier țintă (\fB.xz\fP sau \fB.txz\fP când se comprimă în
+formatul \fB.xz\fP și \fB.lzma\fP sau \fB.tlz\fP când se comprimă în formatul
+\&\fB.lzma\fP).
+.IP \(bu 3
+Modul de operare este stabilit la decomprimare și \fIfișierul\fP nu are un
+sufix al niciunui format de fișier acceptat (\fB.xz\fP, \fB.txz\fP, \fB.lzma\fP,
+\&\fB.tlz\fP, sau \fB.lz\fP).
+.PP
+După comprimarea sau decomprimarea cu succes a \fIfișierului\fP, \fBxz\fP copiază
+proprietarul, grupul, permisiunile, timpul de acces și timpul de modificare
+din \fIfișierul\fP sursă în fișierul țintă.  Dacă copierea grupului eșuează,
+permisiunile sunt modificate astfel încât fișierul țintă să nu devină
+accesibil utilizatorilor care nu aveau permisiunea de a accesa \fIfișierul\fP
+sursă.  \fBxz\fP nu acceptă încă copierea altor metadate, cum ar fi listele de
+control al accesului sau atributele extinse.
+.PP
+Odată ce fișierul țintă a fost închis cu succes, \fIfișierul\fP sursă este
+eliminat dacă nu a fost specificată opțiunea \fB\-\-keep\fP.  \fIFișierul\fP sursă
+nu este niciodată eliminat dacă rezultatul este scris la ieșirea standard
+sau dacă apare o eroare.
+.PP
+Trimiterea unui semnal \fBSIGINFO\fP sau \fBSIGUSR1\fP către procesul \fBxz\fP face
+ca acesta să imprime informații despre progres la ieșirea de eroare
+standard.  Acest lucru are o utilizare limitată, deoarece atunci când
+ieșirea de eroare standard este un terminal, folosind opțiunea \fB\-\-verbose\fP
+va afișa un indicator de progres de actualizare automată.
+.
+.SS "Utilizarea memoriei"
+Cantitatea de memorie utilizată de \fBxz\fP variază de la câteva sute de
+kiloocteți la câțiva gigaocteți, în funcție de opțiunile de comprimare.
+Opțiunile utilizate la comprimarea unui fișier determină cerințele de
+memorie ale instrumentului de decomprimare.  De obicei, instrumentul de
+decomprimare are nevoie de 5% până la 20% din cantitatea de memorie de care
+a avut nevoie instrumentul de comprimare la crearea fișierului.  De exemplu,
+decomprimarea unui fișier creat cu \fBxz \-9\fP necesită în prezent 65Mio de
+memorie.  Totuși, este posibil să aveți fișiere \fB.xz\fP care necesită câțiva
+gigaocteți de memorie pentru decomprimare.
+.PP
+În special utilizatorii de sisteme mai vechi pot considera deranjantă
+posibilitatea unei utilizări foarte mari a memoriei.  Pentru a preveni
+surprizele neplăcute, \fBxz\fP are încorporat un limitator de utilizare a
+memoriei, care este dezactivat implicit.  În timp ce unele sisteme de
+operare oferă modalități de a limita utilizarea memoriei proceselor, bazarea
+pe aceasta nu a fost considerată a fi suficient de flexibilă (de exemplu,
+utilizarea \fBulimit\fP(1) pentru a limita memoria virtuală tinde să paralizeze
+\fBmmap\fP(2)).
+.PP
+Limitatorul de utilizare a memoriei poate fi activat cu opțiunea din linia
+de comandă \fB\-\-memlimit=\fP\fIlimita\fP.  Adesea este mai convenabil să activați
+limitatorul în mod implicit prin definirea variabilei de mediu
+\fBXZ_DEFAULTS\fP, de exemplu, \fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP.  Este posibil
+să stabiliți limitele separat pentru comprimare și decomprimare folosind
+\fB\-\-memlimit\-compress=\fP\fIlimita\fP și \fB\-\-memlimit\-decompress=\fP\fIlimita\fP.
+Utilizarea acestor două opțiuni în afara \fBXZ_DEFAULTS\fP este foarte rar
+utilă, deoarece o singură rulare a \fBxz\fP nu poate face atât comprimarea, cât
+și decomprimarea și \fB\-\-memlimit=\fP\fIlimita\fP (sau \fB\-M\fP \fIlimita\fP ) este mai
+scurt de tastat pe linia de comandă.
+.PP
+Dacă limita de utilizare a memoriei specificată este depășită la
+decomprimare, \fBxz\fP va afișa o eroare și decomprimarea fișierului va eșua.
+Dacă limita este depășită la comprimare, \fBxz\fP va încerca să reducă valorile
+stabilite astfel încât limita să nu mai fie depășită (cu excepția cazului în
+care se utilizează opțiunea \fB\-\-format=raw\fP sau \fB\-\-no\-adjust\fP).  În acest
+fel, operațiunea nu va eșua decât dacă limita stabilită este foarte mică.
+Scalarea valorilor stabilite se face în pași care nu se potrivesc cu
+valorile prestabilite ale nivelului de comprimare, de exemplu, dacă limita
+este doar puțin mai mică decât cantitatea necesară pentru \fBxz \-9\fP, valorile
+stabilite vor fi reduse doar puțin , nu până la valoarea prestabilită a lui
+\fBxz \-8\fP.
+.
+.SS "Concatenare și completare (prin umplere cu octeți nuli) cu fișiere .xz"
+Este posibil să concatenați fișierele \fB.xz\fP așa cum sunt.  \fBxz\fP va
+decomprima astfel de fișiere ca și cum ar fi un singur fișier \fB.xz\fP.
+.PP
+Este posibil să se introducă umplutură între părțile concatenate sau după
+ultima parte.  Umplutura trebuie să fie compusă din octeți nuli, iar
+dimensiunea umpluturii trebuie să fie un multiplu de patru octeți.  Acest
+lucru poate fi util, de exemplu, dacă fișierul \fB.xz\fP este stocat pe un
+mediu care măsoară dimensiunile fișierelor în blocuri de 512 de octeți.
+.PP
+Concatenarea și completarea nu sunt permise cu fișierele \fB.lzma\fP sau
+fluxurile brute.

+Dimensiunea necomprimată a fișierului poate fi stocată în antetul \fB.lzma\fP.
+LZMA Utils face asta atunci când comprimă fișiere obișnuite.  Alternativa
+este să marcați că dimensiunea necomprimată este necunoscută și să folosiți
+marcajul de sfârșit de încărcare pentru a indica unde ar trebui să se
+oprească decomprimarea.  LZMA Utils folosește această metodă atunci când
+dimensiunea necomprimată nu este cunoscută, ceea ce este cazul, de exemplu,
+când se folosesc conducte.
+.PP
+\fBxz\fP acceptă decomprimarea fișierelor \fB.lzma\fP cu sau fără marcaj de
+sfârșit de încărcare, dar toate fișierele \fB.lzma\fP create de \fBxz\fP vor
+folosi marcajul de sfârșit de încărcare și vor avea dimensiunea necomprimată
+marcată ca necunoscută în antetul \fB.lzma\fP.  Aceasta poate fi o problemă în
+unele situații mai puțin frecvente.  De exemplu, un instrument de
+decomprimare \fB.lzma\fP încorporat într\-un dispozitiv poate funcționa numai cu
+fișiere care au dimensiunea necomprimată cunoscută.  Dacă întâmpinați
+această problemă, trebuie să utilizați LZMA Utils sau LZMA SDK pentru a crea
+fișiere \fB.lzma\fP cu dimensiunea necomprimată cunoscută.
+.
+.SS "Fișiere .lzma neacceptate"
+Formatul \fB.lzma\fP permite valori \fIlc\fP de până la 8 și valori \fIlp\fP de până
+la 4.  LZMA Utils poate decomprima fișiere cu orice \fIlc\fP și \fIlp\fP, dar
+creează întotdeauna fișiere cu \fBlc=3\fP și \fBlp=0\fP.  Crearea de fișiere cu
+alte \fIlc\fP și \fIlp\fP este posibilă cu \fBxz\fP și cu LZMA SDK.
+.PP
+Implementarea filtrului LZMA1 în liblzma necesită ca suma \fIlc\fP și \fIlp\fP să
+nu depășească 4.  Altfel, fișierele \fB.lzma\fP, care depășesc această
+limitare, nu pot fi decomprimate cu \fBxz\fP.
+.PP
+LZMA Utils creează numai fișiere \fB.lzma\fP care au o dimensiune de dicționar
+de 2^\fIn\fP (o putere de 2), dar acceptă fișiere cu orice dimensiune de
+dicționar.  liblzma acceptă numai fișierele \fB.lzma\fP care au dimensiunea de
+dicționar de 2^\fIn\fP sau 2^\fIn\fP + 2^(\fIn\fP\-1).  Acest lucru este pentru a
+reduce numărul de „fals pozitiv” atunci când se detectează fișiere \fB.lzma\fP.
+.PP
+Aceste limitări nu ar trebui să fie o problemă în practică, deoarece practic
+toate fișierele \fB.lzma\fP au fost comprimate cu opțiuni pe care liblzma le va
+accepta.
+.
+.SS "Resturi rămase"
+Când decomprimă, LZMA Utils ignoră în tăcere totul după primul flux
+\&\fB.lzma\fP.  În majoritatea situațiilor, aceasta este o eroare.  Aceasta
+înseamnă, de asemenea, că LZMA Utils nu acceptă decomprimarea fișierelor
+\&\fB.lzma\fP concatenate.
+.PP
+Dacă au rămas date după primul flux \fB.lzma\fP, \fBxz\fP consideră că fișierul
+este corupt, cu excepția cazului în care a fost utilizată opțiunea
+\fB\-\-single\-stream\fP.  Acest lucru poate rupe scripturile obscure(scrise
+deficitar) care presupun că resturile rămase sunt ignorate.
+.
+.SH NOTE
+.
+.SS "Rezultatul comprimării poate varia"
+Ieșirea exactă comprimată produsă din același fișier de intrare necomprimat
+poate varia între versiunile XZ Utils, chiar dacă opțiunile de comprimare
+sunt identice.  Acest lucru se datorează faptului că instrumentul
+codificator poate fi îmbunătățit (comprimare mai rapidă sau mai bună) fără a
+afecta formatul fișierului.  Ieșirea poate varia chiar și între compilările
+diferite ale aceleiași versiuni XZ Utils, dacă sunt utilizate opțiuni
+diferite de compilare.
+.PP
+Cele de mai sus înseamnă că odată ce opțiunea \fB\-\-rsyncable\fP a fost
+utilizată, fișierele rezultate nu vor fi neapărat sincronizate cu rsync
+decât dacă atât fișierele vechi, cât și cele noi au fost comprimate cu
+aceeași versiune xz.  Această problemă poate fi remediată dacă o parte a
+implementării codificatorului este înghețată pentru a menține stabilă
+ieșirea „rsyncabilă” între versiunile xz.
+.
+.SS "Instrumente de decomprimare .xz încorporate"

+\fBlzmadec\fP [\fIopțiune...\fP] [\fIfișier...\fP]
+.SH DESCRIERE
+\fBxzdec\fP este un instrument de decomprimare bazat pe liblzma pentru
+fișierele \fB.xz\fP (și numai \fB.xz\fP).  \fBxzdec\fP este destinat să funcționeze
+ca un înlocuitor pentru \fBxz\fP(1) în cele mai frecvente situații în care un
+script a fost scris pentru a utiliza \fBxz \-\-decompress \-\-stdout\fP (și posibil
+câteva alte opțiuni frecvent utilizate) pentru a decomprima fișierele
+\&\fB.xz\fP.  \fBlzmadec\fP este identic cu \fBxzdec\fP cu excepția faptului că
+\fBlzmadec\fP acceptă fișierele \fB.lzma\fP în loc de fișierele \fB.xz\fP.
+.PP
+Pentru a reduce dimensiunea executabilului, \fBxzdec\fP nu acceptă modul cu mai
+multe fire de execuție sau localizarea(afișarea mesajelor în limba stabilită
+de configurările regionale) și nu citește opțiunile din variabilele de mediu
+\fBXZ_DEFAULTS\fP și \fBXZ_OPT\fP.  \fBxzdec\fP nu acceptă afișarea informațiilor
+intermediare de progres: trimiterea semnalului \fBSIGINFO\fP la \fBxzdec\fP nu
+face nimic, iar trimiterea semnalului \fBSIGUSR1\fP încheie procesul în loc să

+.PP
+\fBxzdec\fP nu are niciun mesaj de avertizare precum \fBxz\fP(1), astfel că starea

+.SH NOTE
+Utilizați \fBxz\fP(1) în loc de \fBxzdec\fP sau \fBlzmadec\fP pentru utilizarea
+normală de zi cu zi.  \fBxzdec\fP sau \fBlzmadec\fP sunt destinate numai
+situațiilor în care este important să aveți un instrument de decomprimare
+mai mic decât \fBxz\fP(1), cu funcții complete.
+.PP
+\fBxzdec\fP și \fBlzmadec\fP nu sunt chiar atât de mici.  Dimensiunea poate fi
+redusă și mai mult prin eliminarea caracteristicilor din liblzma în timpul
+compilării, dar acest lucru nu ar trebui să se facă de obicei pentru
+executabilele distribuite în distribuții tipice de sisteme de operare
+neîncorporate.  Dacă aveți nevoie de un instrument de decomprimare \fB.xz\fP cu

+.SH ОПИС
+\fBxz\fP інструмент загального призначення для стискання даних із синтаксисом
+командного рядка, подібним для \fBgzip\fP(1) і \fBbzip2\fP(1). Власним форматом
+файлів є \fB.xz\fP, але передбачено підтримку застарілого формату \fB.lzma\fP,
+який було використано у LZMA Utils, та необроблених потоків стиснених даних
+без заголовків формату контейнера. Крім того, передбачено підтримку
+розпаковування формату \fB.lz\fP, який використано у \fBlzip\fP.
+.PP
+\fBxz\fP стискає або розпаковує кожен \fIфайл\fP відповідно до вибраного режиму
+дій. Якщо \fIфайли\fP не задано або якщо \fIфайлом\fP є \fB\-\fP, \fBxz\fP читатиме дані
+зі стандартного джерела вхідних даних і записуватиме оброблені дані до
+стандартного виведення. \fBxz\fP відмовить (покаже повідомлення про помилку і
+пропустить \fIфайл\fP) у записів стиснених даних до стандартного виведення,
+якщо це термінал. Так само, \fBxz\fP відмовить у читанні стиснених даних зі
+стандартного джерела вхідних даних, якщо це термінал.
+.PP
+Якщо не вказано \fB\-\-stdout\fP, \fIфайли\fP, відмінні від \fB\-\fP, буде записано до
+нового файла, чию назву буде визначено з назви початкового \fIфайла\fP:

+При стисканні суфікс формату файла призначення (\fB.xz\fP або \fB.lzma\fP) буде
+дописано до назви початкового файла для отримання назви файла призначення.
+.IP \(bu 3
+При розпаковуванні суфікс \fB.xz\fP, \fB.lzma\fP або \fB.lz\fP буде вилучено з назви
+файла для отримання назви файла призначення. Крім того, \fBxz\fP розпізнає
+суфікси \fB.txz\fP і \fB.tlz\fP і замінює їх на суфікс \fB.tar\fP.
+.PP
+Якщо файл призначення вже існує, буде показано повідомлення про помилку, а
+\fIфайл\fP буде пропущено.
+.PP
+Окрім випадку запису до стандартного виведення, \fBxz\fP покаже попередження і
+пропустить обробку \fIфайла\fP, якщо буде виконано будь\-яку з таких умов:
+.IP \(bu 3
+\fIФайл\fP не є звичайним файлом. Програма не переходитиме за символічними
+посиланнями, а отже, не вважатиме їх звичайними файлами.
+.IP \(bu 3
+На \fIфайл\fP існує декілька жорстких посилань.
+.IP \(bu 3
+Для \fIфайла\fP встановлено setuid, setgid або «липкий» біт.
+.IP \(bu 3
+Режим дій встановлено у значення «стискання», і \fIфайл\fP вже має суфікс назви
+формату файла призначення (\fB.xz\fP або \fB.txz\fP при стисканні до формату
+\&\fB.xz\fP, і \fB.lzma\fP або \fB.tlz\fP при стисканні до формату \fB.lzma\fP).
+.IP \(bu 3
+Режим дій встановлено у значення «розпаковування», і \fIфайл\fP не має суфікса
+назви жодного з підтримуваних форматів (\fB.xz\fP, \fB.txz\fP, \fB.lzma\fP, \fB.tlz\fP
+або \fB.lz\fP).
+.PP
+Після успішного стискання або розпаковування \fIфайла\fP, \fBxz\fP копіює дані
+щодо власника, групи, прав доступу, часу доступу та моменту внесення змін з
+початкового \fIфайла\fP до файла призначення. Якщо копіювання даних щодо групи
+зазнає невдачі, права доступу буде змінено так, що файл призначення стане
+недоступним для користувачів, які не мають права доступу до початкового
+\fIфайла\fP. В \fBxz\fP ще не передбачено підтримки копіювання інших метаданих,
+зокрема списків керування доступом або розширених атрибутів.
+.PP
+Щойно файл призначення буде успішно закрито, початковий \fIфайл\fP буде
+вилучено, якщо не вказано параметра \fB\-\-keep\fP. Початковий \fIфайл\fP ніколи не
+буде вилучено, якщо виведені дані буде записано до стандартного виведення
+або якщо станеться помилка.
+.PP
+Надсилання \fBSIGINFO\fP або \fBSIGUSR1\fP до процесу \fBxz\fP призводить до
+виведення даних щодо поступу до стандартного виведення помилок. Це має лише
+обмежене використання, оскільки якщо стандартним виведенням помилок є
+термінал, використання \fB\-\-verbose\fP призведе до показу автоматично
+оновлюваного індикатора поступу.
+.
+.SS "Використання пам'яті"
+Використання \fBxz\fP пам'яті може бути різним: від декількох сотень кілобайтів
+до декількох гігабайтів, залежно від параметрів стискання. Параметри, які
+використано при стисканні файла, визначають вимоги до об'єму пам'яті при
+розпакуванні. Типово, засобу розпаковування потрібно від 5\ % до 20\ %
+об'єму пам'яті, якого засіб стискання потребує при створенні
+файла. Наприклад, розпаковування файла, який створено з використанням \fBxz \-9\fP, у поточній версії потребує 65\ МіБ пам'яті. Втім, можливе створення
+файлів \fB.xz\fP, які потребуватимуть для розпаковування декількох гігабайтів
+пам'яті.
+.PP
+Ймовірність високого рівня використання пам'яті може бути особливо
+дошкульною для користувачів застарілих комп'ютерів. Щоб запобігти прикрим
+несподіванкам, у \fBxz\fP передбачено вбудований обмежувач пам'яті, який типово
+вимкнено. Хоча у деяких операційних системах передбачено спосіб обмежити
+використання пам'яті процесами, сподівання на його ефективність не є аж
+надто гнучким (наприклад, використання \fBulimit\fP(1) для обмеження
+віртуальної пам'яті призводить до викривлення даних \fBmmap\fP(2)).
+.PP
+Обмежувач пам'яті можна увімкнути за допомогою параметра командного рядка
+\fB\-\-memlimit=\fP\fIобмеження\fP. Часто, зручніше увімкнути обмежувач на типовому
+рівні, встановивши значення для змінної середовища \fBXZ_DEFAULTS\fP,
+наприклад, \fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP. Можна встановити обмеження
+окремо для стискання і розпакування за допомогою
+\fB\-\-memlimit\-compress=\fP\fIlimit\fP and
+\fB\-\-memlimit\-decompress=\fP\fIобмеження\fP. Використання цих двох параметрів поза
+\fBXZ_DEFAULTS\fP не таке вже і корисне, оскільки одноразовий запуск \fBxz\fP не
+може одночасно призводити до стискання та розпаковування, а набрати у
+командному рядку \fB\-\-memlimit=\fP\fIобмеження\fP (або \fB\-M\fP \fIобмеження\fP)
+набагато швидше.
+.PP
+Якщо під час розпаковування вказане обмеження буде перевищено, \fBxz\fP покаже
+повідомлення про помилку, а розпаковування файла зазнає невдачі. Якщо
+обмеження буде перевищено при стисканні, \fBxz\fP спробує масштабувати
+параметри так, щоб не перевищувати обмеження (окрім випадків використання
+\fB\-\-format=raw\fP або \fB\-\-no\-adjust\fP). Отже, дію буде виконано, якщо обмеження
+не є надто жорстким. Масштабування параметрів буде виконано кроками, які не
+збігаються із рівнями шаблонів стискання. Наприклад, якщо обмеження лише
+трохи не вкладається у об'єм потрібний для \fBxz \-9\fP, параметри буде змінено
+лише трохи, не до рівня \fBxz \-8\fP.
+.
+.SS "Поєднання і заповнення з файлами .xz"
+Можна поєднати файли \fB.xz\fP без додаткової обробки. \fBxz\fP розпакує такі
+файли так, наче вони є єдиним файлом \fB.xz\fP.
+.PP
+Можна додати доповнення між з'єднаними частинами або після останньої
+частини. Доповнення має складатися із нульових байтів і мати розмір, який є
+кратним до чотирьох байтів. Це може бути корисним, наприклад, якщо файл
+\&\fB.xz\fP зберігається на носії даних, де розміри файла вимірюються у
+512\-байтових блоках.
+.PP
+Поєднання та заповнення не можна використовувати для файлів \fB.lzma\fP або
+потоків необроблених даних.

+.SS "Нетипові ланцюжки фільтрів засобу стискання"
+Нетиповий ланцюжок фільтрування уможливлює докладне визначення параметрів
+стискання замість використання параметрів, які пов'язано із наперед
+визначеними рівнями стискання. Якщо вказано нетиповий ланцюжок фільтрів,
+параметри рівнів стискання (\fB\-0\fP \&...\& \fB\-9\fP і \fB\-\-extreme\fP), які
+передують їм у рядку команди, буде знехтувано. Якщо параметр рівня стискання
+вказано після одного або декількох параметрів нетипового ланцюжка фільтрів,
+буде використано рівень стискання, а попередніми параметрами ланцюжка
+фільтрування буде знехтувано.
+.PP
+Ланцюжок фільтрів можна порівняти із конвеєром у командному рядку. При
+стисканні нестиснені вхідні дані потрапляють до першого фільтра, виведені
+ним дані йдуть до наступного фільтра (якщо такий є). Виведені останнім
+фільтром дані буде записано до стисненого файла. Максимальна кількість
+фільтрів у ланцюжку дорівнює чотирьом, але у типовому ланцюжку фільтрів
+використовують один або два фільтри.
+.PP
+У багатьох фільтрів є обмеження на місце перебування у ланцюжку фільтрів:
+деякі фільтри можуть працювати, лише якщо вони є останніми у ланцюжку,
+деякі, лише якщо не останніми, а деякі працюють у будь\-якій позиції
+ланцюжка. Залежно від фільтра, це обмеження є наслідком структури фільтра
+або існує для запобігання проблем із захистом.
+.PP
+Нетиповий ланцюжок фільтрів визначають за допомогою одного або декількох
+параметрів фільтрування у бажаному для ланцюжка фільтрування порядку. Тобто
+порядок параметрів фільтрування впливає на результат! При декодуванні
+необробленого потоку даних (\fB\-\-format=raw\fP) ланцюжок фільтрів визначають у
+тому самому порядку, який використовують для стискання даних.
+.PP
+Фільтри приймають специфічні для фільтрів \fIпараметри\fP у форматі списку
+значень, які відокремлено комами. Зайві коми у \fIпараметрах\fP буде

+.SS "Потокові і непотокові файл .lzma"
+Розмір нестисненого файла може бути збережено у заголовку \fB.lzma\fP. LZMA
+Utils зберігають дані при стисканні звичайних файлів. Альтернативним
+підходом є позначення нестисненого розміру як невідомого і використання
+позначки кінця вмісту для позначення місця, де засіб розпаковування має
+зупинитися. У LZMA Utils цей спосіб використовують, якщо нестиснений розмір
+є невідомим, що трапляється, наприклад, для конвеєрів обробки даних.
+.PP
+У \fBxz\fP передбачено підтримку розпаковування файлів \fB.lzma\fP з позначкою
+кінця вмісту та без неї, але усі файли \fB.lzma\fP, які створено за допомогою
+\fBxz\fP, використовують позначку кінця вмісту, а нестиснений розмір у
+заголовку \fB.lzma\fP позначають як невідомий. Це може призвести до проблем у
+деяких нетипових ситуаціях. Наприклад, розпакувальник \fB.lzma\fP у вбудованому
+пристрої може працювати лише з файлами, для яких відомий нестиснений
+розмір. Якщо ви зіткнулися з цією проблемою, вам слід скористатися LZMA

+перевищувала 4. Отже, файли \fB.lzma\fP, у яких перевищено обмеження, не може
+бути розпаковано за допомогою \fBxz\fP.
+.PP
+LZMA Utils створюють лише файли \fB.lzma\fP, які мають розмір словника у 2^\fIn\fP

+приймає лише файли \fB.lzma\fP, які мають розмір словника 2^\fIn\fP або 2^\fIn\fP +
+2^(\fIn\fP\-1). Так зроблено для зменшення помилок при виявленні файлів
+\&\fB.lzma\fP.

+Якщо після першого потоку \fB.lzma\fP лишилися дані, \fBxz\fP вважатиме файл

+Зображення слід берегти у нестисненому форматі, наприклад, як нестиснений

+.SH ОПИС
+\fBxzdec\fP є інструментом на основі liblzma, який призначено лише для
+розпаковування файлів \fB.xz\fP (і лише файлів \fB.xz\fP). \fBxzdec\fP призначено для
+того, щоб працювати як повноцінний замінник \fBxz\fP(1) у більшості типових
+ситуацій, де скрипт було написано для використання \fBxz \-\-decompress \-\-stdout\fP (і, можливо, декількох інших типових параметрів), для
+розпаковування файлів \fB.xz\fP. \fBlzmadec\fP є тотожним до \fBxzdec\fP, але у
+\fBlzmadec\fP передбачено підтримку файлів \fB.lzma\fP, замість файлів \fB.xz\fP.
+.PP
+Щоб зменшити розмір виконуваного файла, у \fBxzdec\fP не передбачено підтримки
+багатопотокової обробки та локалізації, а також читання параметрів зі
+змінних середовища \fBXZ_DEFAULTS\fP і \fBXZ_OPT\fP. У \fBxzdec\fP не передбачено
+підтримки показу проміжних даних щодо поступу: надсилання \fBSIGINFO\fP до

+\fBxzdec\fP не має жодних повідомлень із попередженнями, на відміну від

+\fBxzdec\fP і \fBlzmadec\fP не такі вже і малі програми. Їхній розмір можна

+// Unaligned reads and writes //
+////////////////////////////////
+
+// No-strict-align archs like x86-64
+// ---------------------------------
+//
+// The traditional way of casting e.g. *(const uint16_t *)uint8_pointer
+// is bad even if the uint8_pointer is properly aligned because this kind
+// of casts break strict aliasing rules and result in undefined behavior.
+// With unaligned pointers it's even worse: compilers may emit vector
+// instructions that require aligned pointers even if non-vector
+// instructions work with unaligned pointers.
+//
+// Using memcpy() is the standard compliant way to do unaligned access.
+// Many modern compilers inline it so there is no function call overhead.
+// For those compilers that don't handle the memcpy() method well, the
+// old casting method (that violates strict aliasing) can be requested at
+// build time. A third method, casting to a packed struct, would also be
+// an option but isn't provided to keep things simpler (it's already a mess).
+// Hopefully this is flexible enough in practice.
+//
+// Some compilers on x86-64 like Clang >= 10 and GCC >= 5.1 detect that
+//
+//     buf[0] | (buf[1] << 8)
+//
+// reads a 16-bit value and can emit a single 16-bit load and produce
+// identical code than with the memcpy() method. In other cases Clang and GCC
+// produce either the same or better code with memcpy(). For example, Clang 9
+// on x86-64 can detect 32-bit load but not 16-bit load.
+//
+// MSVC uses unaligned access with the memcpy() method but emits byte-by-byte
+// code for "buf[0] | (buf[1] << 8)".
+//
+// Conclusion: The memcpy() method is the best choice when unaligned access
+// is supported.
+//
+// Strict-align archs like SPARC
+// -----------------------------
+//
+// GCC versions from around 4.x to to at least 13.2.0 produce worse code
+// from the memcpy() method than from simple byte-by-byte shift-or code
+// when reading a 32-bit integer:
+//
+//     (1) It may be constructed on stack using using four 8-bit loads,
+//         four 8-bit stores to stack, and finally one 32-bit load from stack.
+//
+//     (2) Especially with -Os, an actual memcpy() call may be emitted.
+//
+// This is true on at least on ARM, ARM64, SPARC, SPARC64, MIPS64EL, and
+// RISC-V. Of these, ARM, ARM64, and RISC-V support unaligned access in
+// some processors but not all so this is relevant only in the case when
+// GCC assumes that unaligned is not supported or -mstrict-align or
+// -mno-unaligned-access is used.
+//
+// For Clang it makes little difference. ARM64 with -O2 -mstrict-align
+// was one the very few with a minor difference: the memcpy() version
+// was one instruction longer.
+//
+// Conclusion: At least in case of GCC and Clang, byte-by-byte code is
+// the best choise for strict-align archs to do unaligned access.
+//
+// See also: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111502

+// Aligned reads and writes //
+//////////////////////////////
+
+// Separate functions for aligned reads and writes are provided since on
+// strict-align archs aligned access is much faster than unaligned access.
+//
+// Just like in the unaligned case, memcpy() is needed to avoid
+// strict aliasing violations. However, on archs that don't support
+// unaligned access the compiler cannot know that the pointers given
+// to memcpy() are aligned which results in slow code. As of C11 there is
+// no standard way to tell the compiler that we know that the address is
+// aligned but some compilers have language extensions to do that. With
+// such language extensions the memcpy() method gives excellent results.
+//
+// What to do on a strict-align system when no known language extentensions
+// are available? Falling back to byte-by-byte access would be safe but ruin
+// optimizations that have been made specifically with aligned access in mind.
+// As a compromise, aligned reads will fall back to non-compliant type punning
+// but aligned writes will be byte-by-byte, that is, fast reads are preferred
+// over fast writes. This obviously isn't great but hopefully it's a working
+// compromise for now.

+ * \file        api/lzma.h
+ * \brief       The public API of liblzma data compression library
+ * \mainpage
+ *
+ * liblzma is a public domain general-purpose data compression library with
+ * a zlib-like API. The native file format is .xz, but also the old .lzma
+ * format and raw (no headers) streams are supported. Multiple compression
+ * algorithms (filters) are supported. Currently LZMA2 is the primary filter.
+ *
+ * liblzma is part of XZ Utils <https://tukaani.org/xz/>. XZ Utils includes
+ * a gzip-like command line tool named xz and some other tools. XZ Utils
+ * is developed and maintained by Lasse Collin and Jia Tan.
+ *
+ * Major parts of liblzma are based on Igor Pavlov's public domain LZMA SDK
+ * <https://7-zip.org/sdk.html>.
+ *
+ * The SHA-256 implementation is based on the public domain code found from
+ * 7-Zip <https://7-zip.org/>, which has a modified version of the public
+ * domain SHA-256 code found from Crypto++ <https://www.cryptopp.com/>.
+ * The SHA-256 code in Crypto++ was written by Kevin Springle and Wei Dai.

+/*****************************
+ * Required standard headers *
+ *****************************/
+
+/*
+ * liblzma API headers need some standard types and macros. To allow
+ * including lzma.h without requiring the application to include other
+ * headers first, lzma.h includes the required standard headers unless
+ * they already seem to be included already or if LZMA_MANUAL_HEADERS
+ * has been defined.
+ *
+ * Here's what types and macros are needed and from which headers:
+ *  - stddef.h: size_t, NULL
+ *  - stdint.h: uint8_t, uint32_t, uint64_t, UINT32_C(n), uint64_C(n),
+ *    UINT32_MAX, UINT64_MAX
+ *
+ * However, inttypes.h is a little more portable than stdint.h, although
+ * inttypes.h declares some unneeded things compared to plain stdint.h.
+ *
+ * The hacks below aren't perfect, specifically they assume that inttypes.h
+ * exists and that it typedefs at least uint8_t, uint32_t, and uint64_t,
+ * and that, in case of incomplete inttypes.h, unsigned int is 32-bit.
+ * If the application already takes care of setting up all the types and
+ * macros properly (for example by using gnulib's stdint.h or inttypes.h),
+ * we try to detect that the macros are already defined and don't include
+ * inttypes.h here again. However, you may define LZMA_MANUAL_HEADERS to
+ * force this file to never include any system headers.
+ *
+ * Some could argue that liblzma API should provide all the required types,
+ * for example lzma_uint64, LZMA_UINT64_C(n), and LZMA_UINT64_MAX. This was
+ * seen as an unnecessary mess, since most systems already provide all the
+ * necessary types and macros in the standard headers.
+ *
+ * Note that liblzma API still has lzma_bool, because using stdbool.h would
+ * break C89 and C++ programs on many systems. sizeof(bool) in C99 isn't
+ * necessarily the same as sizeof(bool) in C++.

+ * \brief       MicroLZMA encoder
+ *
+ * The MicroLZMA format is a raw LZMA stream whose first byte (always 0x00)
+ * has been replaced with bitwise-negation of the LZMA properties (lc/lp/pb).
+ * This encoding ensures that the first byte of MicroLZMA stream is never
+ * 0x00. There is no end of payload marker and thus the uncompressed size
+ * must be stored separately. For the best error detection the dictionary
+ * size should be stored separately as well but alternatively one may use
+ * the uncompressed size as the dictionary size when decoding.
+ *
+ * With the MicroLZMA encoder, lzma_code() behaves slightly unusually.
+ * The action argument must be LZMA_FINISH and the return value will never be
+ * LZMA_OK. Thus the encoding is always done with a single lzma_code() after
+ * the initialization. The benefit of the combination of initialization
+ * function and lzma_code() is that memory allocations can be re-used for
+ * better performance.
+ *
+ * lzma_code() will try to encode as much input as is possible to fit into
+ * the given output buffer. If not all input can be encoded, the stream will
+ * be finished without encoding all the input. The caller must check both
+ * input and output buffer usage after lzma_code() (total_in and total_out
+ * in lzma_stream can be convenient). Often lzma_code() can fill the output
+ * buffer completely if there is a lot of input, but sometimes a few bytes
+ * may remain unused because the next LZMA symbol would require more space.
+ *
+ * lzma_stream.avail_out must be at least 6. Otherwise LZMA_PROG_ERROR
+ * will be returned.
+ *
+ * The LZMA dictionary should be reasonably low to speed up the encoder
+ * re-initialization. A good value is bigger than the resulting
+ * uncompressed size of most of the output chunks. For example, if output
+ * size is 4 KiB, dictionary size of 32 KiB or 64 KiB is good. If the
+ * data compresses extremely well, even 128 KiB may be useful.
+ *
+ * The MicroLZMA format and this encoder variant were made with the EROFS
+ * file system in mind. This format may be convenient in other embedded
+ * uses too where many small streams are needed. XZ Embedded includes a
+ * decoder for this format.

+ *   - Files in the format version 0 were produced by lzip 1.3 and older.
+ *     Such files aren't common but may be found from file archives
+ *     as a few source packages were released in this format. People
+ *     might have old personal files in this format too. Decompression
+ *     support for the format version 0 was removed in lzip 1.18.
+ *
+ *   - lzip 1.3 added decompression support for .lz format version 1 files.
+ *     Compression support was added in lzip 1.4. In lzip 1.6 the .lz format
+ *     version 1 was extended to support the Sync Flush marker. This extension
+ *     is not supported by liblzma. lzma_code() will return LZMA_DATA_ERROR
+ *     at the location of the Sync Flush marker. In practice files with
+ *     the Sync Flush marker are very rare and thus liblzma can decompress
+ *     almost all .lz files.
+ *
+ * Just like with lzma_stream_decoder() for .xz files, LZMA_CONCATENATED
+ * should be used when decompressing normal standalone .lz files.
+ *
+ * The .lz format allows putting non-.lz data at the end of a file after at
+ * least one valid .lz member. That is, one can append custom data at the end
+ * of a .lz file and the decoder is required to ignore it. In liblzma this
+ * is relevant only when LZMA_CONCATENATED is used. In that case lzma_code()
+ * will return LZMA_STREAM_END and leave lzma_stream.next_in pointing to
+ * the first byte of the non-.lz data. An exception to this is if the first
+ * 1-3 bytes of the non-.lz data are identical to the .lz magic bytes
+ * (0x4C, 0x5A, 0x49, 0x50; "LZIP" in US-ASCII). In such a case the 1-3 bytes
+ * will have been ignored by lzma_code(). If one wishes to locate the non-.lz
+ * data reliably, one must ensure that the first byte isn't 0x4C. Actually
+ * one should ensure that none of the first four bytes of trailing data are

+ * This tries to make it easier to write applications that allow users
+ * to set custom compression options. This only handles the filter
+ * configuration (including presets) but not the number of threads,
+ * block size, check type, or memory limits.
+ *
+ * The input string can be either a preset or a filter chain. Presets
+ * begin with a digit 0-9 and may be followed by zero or more flags
+ * which are lower-case letters. Currently only "e" is supported, matching
+ * LZMA_PRESET_EXTREME. For partial xz command line syntax compatibility,
+ * a preset string may start with a single dash "-".
+ *
+ * A filter chain consists of one or more "filtername:opt1=value1,opt2=value2"
+ * strings separated by one or more spaces. Leading and trailing spaces are
+ * ignored. All names and values must be lower-case. Extra commas in the
+ * option list are ignored. The order of filters is significant: when
+ * encoding, the uncompressed input data goes to the leftmost filter first.
+ * Normally "lzma2" is the last filter in the chain.
+ *
+ * If one wishes to avoid spaces, for example, to avoid shell quoting,
+ * it is possible to use two dashes "--" instead of spaces to separate
+ * the filters.
+ *
+ * For xz command line compatibility, each filter may be prefixed with
+ * two dashes "--" and the colon ":" separating the filter name from
+ * the options may be replaced with an equals sign "=".
+ *
+ * By default, only filters that can be used in the .xz format are accepted.
+ * To allow all filters (LZMA1) use the flag LZMA_STR_ALL_FILTERS.
+ *
+ * By default, very basic validation is done for the filter chain as a whole,
+ * for example, that LZMA2 is only used as the last filter in the chain.
+ * The validation isn't perfect though and it's possible that this function
+ * succeeds but using the filter chain for encoding or decoding will still
+ * result in LZMA_OPTIONS_ERROR. To disable this validation, use the flag
+ * LZMA_STR_NO_VALIDATION.

+ *
+ * To get the required information from the .xz file, lzma_code() may ask

+/// and the public domain code from https://github.com/rawrunprotected/crc
+/// (URLs were checked on 2022-11-07).

+/// FIXME: Builds for 32-bit x86 use crc64_x86.S by default instead
+/// of this file and thus CLMUL version isn't available on 32-bit x86
+/// unless configured with --disable-assembler. Even then the lookup table
+/// isn't omitted in crc64_table.c since it doesn't know that assembly

+/// \file       sha256.c
+/// \brief      SHA-256
+///
+/// \todo       Crypto++ has x86 ASM optimizations. They use SSE so if they
+///             are imported to liblzma, SSE instructions need to be used
+///             conditionally to keep the code working on older boxes.
+//
+//  This code is based on the code found from 7-Zip, which has a modified
+//  version of the SHA-256 found from Crypto++ <https://www.cryptopp.com/>.
+//  The code was modified a little to fit into liblzma.

+/// \brief      Biggest Compressed Size value that the Block encoder supports
+///
+/// The maximum size of a single Block is limited by the maximum size of
+/// a Stream, which in theory is 2^63 - 3 bytes (i.e. LZMA_VLI_MAX - 3).
+/// While the size is really big and no one should hit it in practice, we
+/// take it into account in some places anyway to catch some errors e.g. if
+/// application passes insanely big value to some function.
+///
+/// We could take into account the headers etc. to determine the exact
+/// maximum size of the Compressed Data field, but the complexity would give
+/// us nothing useful. Instead, limit the size of Compressed Data so that
+/// even with biggest possible Block Header and Check fields the total
+/// encoded size of the Block stays as a valid VLI. This doesn't guarantee
+/// that the size of the Stream doesn't grow too big, but that problem is
+/// taken care outside the Block handling code.
+///
+/// ~LZMA_VLI_C(3) is to guarantee that if we need padding at the end of
+/// the Compressed Data field, it will still stay in the proper limit.
+///
+/// This constant is in this file because it is needed in both
+/// block_encoder.c and block_buffer_encoder.c.

+/// When converting a string to filter options structure, option values
+/// will be handled in a few different ways:
+///
+/// (1) If .type equals OPTMAP_TYPE_LZMA_PRESET then LZMA1/2 preset string
+///     is handled specially.

+/// (3) Otherwise the string is treated as a non-negative unsigned decimal
+///     integer which must be in the range set in .u.range. If .flags has
+///     OPTMAP_USE_BYTE_SUFFIX then KiB, MiB, and GiB suffixes are allowed.
+///
+/// The integer value from (2) or (3) is then stored to filter_options

+/// (default is uint32_t).
+///
+/// Stringifying a filter is done by processing a given number of options
+/// in order from the beginning of an option_map array. The integer is
+/// read from filter_options at .offset using the type from .type.
+///
+/// If the integer is zero and .flags has OPTMAP_NO_STRFY_ZERO then the
+/// option is skipped.
+///
+/// If .flags has OPTMAP_USE_NAME_VALUE_MAP set then .u.map will be used
+/// to convert the option to a string. If the map doesn't contain a string
+/// for the integer value then "UNKNOWN" is used.
+///
+/// If .flags doesn't have OPTMAP_USE_NAME_VALUE_MAP set then the integer is

+// LZMA encodes match distances by storing the highest two bits using
+// a six-bit value [0, 63], and then the missing lower bits.
+// Dictionary size is also stored using this encoding in the .xz
+// file format header.
+//
+// fastpos.h provides a way to quickly find out the correct six-bit
+// values. The following table gives some examples of this encoding:
+//
+//     dist   return
+//       0       0
+//       1       1
+//       2       2
+//       3       3
+//       4       4
+//       5       4
+//       6       5
+//       7       5
+//       8       6
+//      11       6
+//      12       7
+//     ...      ...
+//      15       7

+//     ...      ...
+//
+//
+// Provided functions or macros
+// ----------------------------
+//
+// get_dist_slot(dist) is the basic version. get_dist_slot_2(dist)
+// assumes that dist >= FULL_DISTANCES, thus the result is at least
+// FULL_DISTANCES_BITS * 2. Using get_dist_slot(dist) instead of
+// get_dist_slot_2(dist) would give the same result, but get_dist_slot_2(dist)
+// should be tiny bit faster due to the assumption being made.
+//
+//
+// Size vs. speed
+// --------------
+//
+// With some CPUs that have fast BSR (bit scan reverse) instruction, the
+// size optimized version is slightly faster than the bigger table based
+// approach. Such CPUs include Intel Pentium Pro, Pentium II, Pentium III
+// and Core 2 (possibly others). AMD K7 seems to have slower BSR, but that
+// would still have speed roughly comparable to the table version. Older
+// x86 CPUs like the original Pentium have very slow BSR; on those systems
+// the table version is a lot faster.
+//
+// On some CPUs, the table version is a lot faster when using position
+// dependent code, but with position independent code the size optimized
+// version is slightly faster. This occurs at least on 32-bit SPARC (no
+// ASM optimizations).
+//
+// I'm making the table version the default, because that has good speed
+// on all systems I have tried. The size optimized version is sometimes
+// slightly faster, but sometimes it is a lot slower.

+/// This needs to be at least 12-bit integer, so uint16_t is a logical choice.
+/// However, on some architecture and compiler combinations, a bigger type
+/// may give better speed, because the probability variables are accessed
+/// a lot. On the other hand, bigger probability type increases cache
+/// footprint, since there are 2 to 14 thousand probability variables in
+/// LZMA (assuming the limit of lc + lp <= 4; with lc + lp <= 12 there
+/// would be about 1.5 million variables).
+///
+/// With malicious files, the initialization speed of the LZMA decoder can
+/// become important. In that case, smaller probability variables mean that
+/// there is less bytes to write to RAM, which makes initialization faster.
+/// With big probability type, the initialization can become so slow that it
+/// can be a problem e.g. for email servers doing virus scanning.
+///
+/// I will be sticking to uint16_t unless some specific architectures
+/// are *much* faster (20-50 %) with uint32_t.

+###############################################################################
+#
+# Check liblzma_*.map for certain types of errors.
+#
+# liblzma_generic.map is for FreeBSD and Solaris and possibly others
+# except GNU/Linux.
+#
+# liblzma_linux.map is for GNU/Linux only. This and the matching extra code
+# in the .c files make liblzma >= 5.2.7 compatible with binaries that were
+# linked against ill-patched liblzma in RHEL/CentOS 7. By providing the
+# compatibility in official XZ Utils release will hopefully prevent people
+# from further copying the broken patch to other places when they want
+# compatibility with binaries linked on RHEL/CentOS 7. The long version
+# of the story:
+#
+#     RHEL/CentOS 7 shipped with 5.1.2alpha, including the threaded
+#     encoder that is behind #ifdef LZMA_UNSTABLE in the API headers.
+#     In 5.1.2alpha these symbols are under XZ_5.1.2alpha in liblzma.map.
+#     API/ABI compatibility tracking isn't done between development
+#     releases so newer releases didn't have XZ_5.1.2alpha anymore.
+#
+#     Later RHEL/CentOS 7 updated xz to 5.2.2 but they wanted to keep
+#     the exported symbols compatible with 5.1.2alpha. After checking
+#     the ABI changes it turned out that >= 5.2.0 ABI is backward
+#     compatible with the threaded encoder functions from 5.1.2alpha
+#     (but not vice versa as fixes and extensions to these functions
+#     were made between 5.1.2alpha and 5.2.0).
+#
+#     In RHEL/CentOS 7, XZ Utils 5.2.2 was patched with
+#     xz-5.2.2-compat-libs.patch to modify liblzma.map:
+#
+#       - XZ_5.1.2alpha was added with lzma_stream_encoder_mt and
+#         lzma_stream_encoder_mt_memusage. This matched XZ Utils 5.1.2alpha.
+#
+#       - XZ_5.2 was replaced with XZ_5.2.2. It is clear that this was
+#         an error; the intention was to keep using XZ_5.2 (XZ_5.2.2
+#         has never been used in XZ Utils). So XZ_5.2.2 lists all
+#         symbols that were listed under XZ_5.2 before the patch.
+#         lzma_stream_encoder_mt and _mt_memusage are included too so
+#         they are listed both here and under XZ_5.1.2alpha.
+#
+#     The patch didn't add any __asm__(".symver ...") lines to the .c
+#     files. Thus the resulting liblzma.so exports the threaded encoder
+#     functions under XZ_5.1.2alpha only. Listing the two functions
+#     also under XZ_5.2.2 in liblzma.map has no effect without
+#     matching .symver lines.
+#
+#     The lack of XZ_5.2 in RHEL/CentOS 7 means that binaries linked
+#     against unpatched XZ Utils 5.2.x won't run on RHEL/CentOS 7.
+#     This is unfortunate but this alone isn't too bad as the problem
+#     is contained within RHEL/CentOS 7 and doesn't affect users
+#     of other distributions. It could also be fixed internally in
+#     RHEL/CentOS 7.
+#
+#     The second problem is more serious: In XZ Utils 5.2.2 the API
+#     headers don't have #ifdef LZMA_UNSTABLE for obvious reasons.
+#     This is true in RHEL/CentOS 7 version too. Thus now programs
+#     using new APIs can be compiled without an extra #define. However,
+#     the programs end up depending on symbol version XZ_5.1.2alpha
+#     (and possibly also XZ_5.2.2) instead of XZ_5.2 as they would
+#     with an unpatched XZ Utils 5.2.2. This means that such binaries
+#     won't run on other distributions shipping XZ Utils >= 5.2.0 as
+#     they don't provide XZ_5.1.2alpha or XZ_5.2.2; they only provide
+#     XZ_5.2 (and XZ_5.0). (This includes RHEL/CentOS 8 as the patch
+#     luckily isn't included there anymore with XZ Utils 5.2.4.)
+#
+#     Binaries built by RHEL/CentOS 7 users get distributed and then
+#     people wonder why they don't run on some other distribution.
+#     Seems that people have found out about the patch and been copying
+#     it to some build scripts, seemingly curing the symptoms but
+#     actually spreading the illness further and outside RHEL/CentOS 7.
+#     Adding compatibility in an official XZ Utils release should work
+#     as a vaccine against this ill patch and stop it from spreading.
+#     The vaccine is kept GNU/Linux-only as other OSes should be immune
+#     (hopefully it hasn't spread via some build script to other OSes).

+.TH LZMAINFO 1 "2013-06-30" "Tukaani" "XZ Utils"
+.SH NAME
+lzmainfo \- show information stored in the .lzma file header
+.SH SYNOPSIS
+.B lzmainfo
+.RB [ \-\-help ]
+.RB [ \-\-version ]
+.RI [ file... ]
+.SH DESCRIPTION
+.B lzmainfo
+shows information stored in the
+.B .lzma
+file header.
+It reads the first 13 bytes from the specified
+.IR file ,
+decodes the header, and prints it to standard output in human
+readable format.
+If no
+.I files
+are given or
+.I file
+is
+.BR \- ,
+standard input is read.
+.PP
+Usually the most interesting information is
+the uncompressed size and the dictionary size.
+Uncompressed size can be shown only if
+the file is in the non-streamed
+.B .lzma
+format variant.
+The amount of memory required to decompress the file is
+a few dozen kilobytes plus the dictionary size.
+.PP
+.B lzmainfo
+is included in XZ Utils primarily for
+backward compatibility with LZMA Utils.
+.SH "EXIT STATUS"
+.TP
+.B 0
+All is good.
+.TP
+.B 1
+An error occurred.
+.SH BUGS
+.B lzmainfo
+uses
+.B MB
+while the correct suffix would be
+.B MiB
+(2^20 bytes).
+This is to keep the output compatible with LZMA Utils.
+.SH "SEE ALSO"
+.BR xz (1)

+.RI [ cmp_options "] " file1 " [" file2 ]
+.br
+.B xzdiff
+.RI [ diff_options "] " file1 " [" file2 ]
+.br
+.B lzcmp
+.RI [ cmp_options "] " file1 " [" file2 ]
+.br
+.B lzdiff
+.RI [ diff_options "] " file1 " [" file2 ]
+.SH DESCRIPTION
+.B xzcmp
+and
+.B xzdiff
+invoke
+.BR cmp (1)
+or
+.BR diff (1)
+on files compressed with
+.BR xz (1),
+.BR lzma (1),
+.BR gzip (1),
+.BR bzip2 (1),
+.BR lzop (1),
+or
+.BR zstd (1).
+All options specified are passed directly to
+.BR cmp (1)
+or
+.BR diff (1).
+If only one file is specified, then the files compared are
+.I file1
+(which must have a suffix of a supported compression format) and
+.I file1
+from which the compression format suffix has been stripped.
+If two files are specified,
+then they are uncompressed if necessary and fed to
+.BR cmp (1)
+or
+.BR diff (1).
+The exit status from
+.BR cmp (1)
+or
+.BR diff (1)
+is preserved unless a decompression error occurs; then exit status is 2.
+.PP
+The names
+.B lzcmp
+and
+.B lzdiff
+are provided for backward compatibility with LZMA Utils.
+.SH "SEE ALSO"

+.BR zdiff (1)
+.SH BUGS
+Messages from the
+.BR cmp (1)
+or
+.BR diff (1)
+programs refer to temporary filenames instead of those specified.

+.SH NAME
+xzless, lzless \- view xz or lzma compressed (text) files
+.SH SYNOPSIS
+.B xzless
+.RI [ file ...]
+.br
+.B lzless
+.RI [ file ...]
+.SH DESCRIPTION
+.B xzless
+is a filter that displays text from compressed files to a terminal.
+It works on files compressed with
+.BR xz (1)
+or
+.BR lzma (1).
+If no
+.I files
+are given,
+.B xzless
+reads from standard input.
+.PP
+.B xzless
+uses
+.BR less (1)
+to present its output.
+Unlike
+.BR xzmore ,
+its choice of pager cannot be altered by
+setting an environment variable.
+Commands are based on both
+.BR more (1)
+and
+.BR vi (1)
+and allow back and forth movement and searching.
+See the
+.BR less (1)
+manual for more information.
+.PP
+The command named
+.B lzless
+is provided for backward compatibility with LZMA Utils.
+.SH ENVIRONMENT
+.TP
+.B LESSMETACHARS
+A list of characters special to the shell.
+Set by
+.B xzless
+unless it is already set in the environment.
+.TP
+.B LESSOPEN
+Set to a command line to invoke the
+.BR xz (1)
+decompressor for preprocessing the input files to
+.BR less (1).

+.PP
+When writing scripts that need to decompress files,
+it is recommended to always use the name
+.B xz
+with appropriate arguments
+.RB ( "xz \-d"
+or
+.BR "xz \-dc" )
+instead of the names
+.B unxz
+and
+.BR xzcat .
+.
+.SH DESCRIPTION
+.B xz
+is a general-purpose data compression tool with
+command line syntax similar to
+.BR gzip (1)
+and
+.BR bzip2 (1).
+The native file format is the
+.B .xz
+format, but the legacy
+.B .lzma
+format used by LZMA Utils and
+raw compressed streams with no container format headers
+are also supported.
+In addition, decompression of the
+.B .lz
+format used by
+.B lzip
+is supported.
+.PP
+.B xz
+compresses or decompresses each
+.I file
+according to the selected operation mode.
+If no
+.I files
+are given or
+.I file
+is
+.BR \- ,
+.B xz
+reads from standard input and writes the processed data
+to standard output.
+.B xz
+will refuse (display an error and skip the
+.IR file )
+to write compressed data to standard output if it is a terminal.
+Similarly,
+.B xz
+will refuse to read compressed data
+from standard input if it is a terminal.
+.PP
+Unless
+.B \-\-stdout
+is specified,
+.I files
+other than
+.B \-
+are written to a new file whose name is derived from the source
+.I file
+name:
+.IP \(bu 3
+When compressing, the suffix of the target file format
+.RB ( .xz
+or
+.BR .lzma )
+is appended to the source filename to get the target filename.
+.IP \(bu 3
+When decompressing, the
+.BR .xz ,
+.BR .lzma ,
+or
+.B .lz
+suffix is removed from the filename to get the target filename.
+.B xz
+also recognizes the suffixes
+.B .txz
+and
+.BR .tlz ,
+and replaces them with the
+.B .tar
+suffix.
+.PP
+If the target file already exists, an error is displayed and the
+.I file
+is skipped.
+.PP
+Unless writing to standard output,
+.B xz
+will display a warning and skip the
+.I file
+if any of the following applies:
+.IP \(bu 3
+.I File
+is not a regular file.
+Symbolic links are not followed,
+and thus they are not considered to be regular files.
+.IP \(bu 3
+.I File
+has more than one hard link.
+.IP \(bu 3
+.I File
+has setuid, setgid, or sticky bit set.
+.IP \(bu 3
+The operation mode is set to compress and the
+.I file
+already has a suffix of the target file format
+.RB ( .xz
+or
+.B .txz
+when compressing to the
+.B .xz
+format, and
+.B .lzma
+or
+.B .tlz
+when compressing to the
+.B .lzma
+format).
+.IP \(bu 3
+The operation mode is set to decompress and the
+.I file
+doesn't have a suffix of any of the supported file formats
+.RB ( .xz ,
+.BR .txz ,
+.BR .lzma ,
+.BR .tlz ,
+or
+.BR .lz ).
+.PP
+After successfully compressing or decompressing the
+.IR file ,
+.B xz
+copies the owner, group, permissions, access time,
+and modification time from the source
+.I file
+to the target file.
+If copying the group fails, the permissions are modified
+so that the target file doesn't become accessible to users
+who didn't have permission to access the source
+.IR file .
+.B xz
+doesn't support copying other metadata like access control lists
+or extended attributes yet.
+.PP
+Once the target file has been successfully closed, the source
+.I file
+is removed unless
+.B \-\-keep
+was specified.
+The source
+.I file
+is never removed if the output is written to standard output
+or if an error occurs.
+.PP
+Sending
+.B SIGINFO
+or
+.B SIGUSR1
+to the
+.B xz
+process makes it print progress information to standard error.
+This has only limited use since when standard error
+is a terminal, using
+.B \-\-verbose
+will display an automatically updating progress indicator.
+.
+.SS "Memory usage"
+The memory usage of
+.B xz
+varies from a few hundred kilobytes to several gigabytes
+depending on the compression settings.
+The settings used when compressing a file determine
+the memory requirements of the decompressor.
+Typically the decompressor needs 5\ % to 20\ % of
+the amount of memory that the compressor needed when
+creating the file.
+For example, decompressing a file created with
+.B xz \-9
+currently requires 65\ MiB of memory.
+Still, it is possible to have
+.B .xz
+files that require several gigabytes of memory to decompress.
+.PP
+Especially users of older systems may find
+the possibility of very large memory usage annoying.
+To prevent uncomfortable surprises,
+.B xz
+has a built-in memory usage limiter, which is disabled by default.
+While some operating systems provide ways to limit
+the memory usage of processes, relying on it
+wasn't deemed to be flexible enough (for example, using
+.BR ulimit (1)
+to limit virtual memory tends to cripple
+.BR mmap (2)).
+.PP
+The memory usage limiter can be enabled with
+the command line option \fB\-\-memlimit=\fIlimit\fR.
+Often it is more convenient to enable the limiter
+by default by setting the environment variable
+.BR XZ_DEFAULTS ,
+for example,
+.BR XZ_DEFAULTS=\-\-memlimit=150MiB .
+It is possible to set the limits separately
+for compression and decompression by using
+.BI \-\-memlimit\-compress= limit
+and \fB\-\-memlimit\-decompress=\fIlimit\fR.
+Using these two options outside
+.B XZ_DEFAULTS
+is rarely useful because a single run of
+.B xz
+cannot do both compression and decompression and
+.BI \-\-memlimit= limit
+(or
+.B \-M
+.IR limit )
+is shorter to type on the command line.
+.PP
+If the specified memory usage limit is exceeded when decompressing,
+.B xz
+will display an error and decompressing the file will fail.
+If the limit is exceeded when compressing,
+.B xz
+will try to scale the settings down so that the limit
+is no longer exceeded (except when using
+.B \-\-format=raw
+or
+.BR \-\-no\-adjust ).
+This way the operation won't fail unless the limit is very small.
+The scaling of the settings is done in steps that don't
+match the compression level presets, for example, if the limit is
+only slightly less than the amount required for
+.BR "xz \-9" ,
+the settings will be scaled down only a little,
+not all the way down to
+.BR "xz \-8" .
+.
+.SS "Concatenation and padding with .xz files"
+It is possible to concatenate
+.B .xz
+files as is.
+.B xz
+will decompress such files as if they were a single
+.B .xz
+file.
+.PP
+It is possible to insert padding between the concatenated parts
+or after the last part.
+The padding must consist of null bytes and the size
+of the padding must be a multiple of four bytes.
+This can be useful, for example, if the
+.B .xz
+file is stored on a medium that measures file sizes
+in 512-byte blocks.
+.PP
+Concatenation and padding are not allowed with
+.B .lzma
+files or raw streams.
+.
+.SH OPTIONS
+.
+.SS "Integer suffixes and special values"
+In most places where an integer argument is expected,
+an optional suffix is supported to easily indicate large integers.
+There must be no space between the integer and the suffix.

+The default preset level in LZMA Utils is
+.B \-7
+while in XZ Utils it is
+.BR \-6 ,
+so both use an 8 MiB dictionary by default.
+.
+.SS "Streamed vs. non-streamed .lzma files"
+The uncompressed size of the file can be stored in the
+.B .lzma
+header.
+LZMA Utils does that when compressing regular files.
+The alternative is to mark that uncompressed size is unknown
+and use end-of-payload marker to indicate
+where the decompressor should stop.
+LZMA Utils uses this method when uncompressed size isn't known,
+which is the case, for example, in pipes.
+.PP
+.B xz
+supports decompressing
+.B .lzma
+files with or without end-of-payload marker, but all
+.B .lzma
+files created by
+.B xz
+will use end-of-payload marker and have uncompressed size
+marked as unknown in the
+.B .lzma
+header.
+This may be a problem in some uncommon situations.
+For example, a
+.B .lzma
+decompressor in an embedded device might work
+only with files that have known uncompressed size.
+If you hit this problem, you need to use LZMA Utils
+or LZMA SDK to create
+.B .lzma
+files with known uncompressed size.
+.
+.SS "Unsupported .lzma files"
+The
+.B .lzma
+format allows
+.I lc
+values up to 8, and
+.I lp
+values up to 4.
+LZMA Utils can decompress files with any
+.I lc
+and
+.IR lp ,
+but always creates files with
+.B lc=3
+and
+.BR lp=0 .
+Creating files with other
+.I lc
+and
+.I lp
+is possible with
+.B xz
+and with LZMA SDK.
+.PP
+The implementation of the LZMA1 filter in liblzma
+requires that the sum of
+.I lc
+and
+.I lp
+must not exceed 4.
+Thus,
+.B .lzma
+files, which exceed this limitation, cannot be decompressed with
+.BR xz .
+.PP
+LZMA Utils creates only
+.B .lzma
+files which have a dictionary size of
+.RI "2^" n
+(a power of 2) but accepts files with any dictionary size.
+liblzma accepts only
+.B .lzma
+files which have a dictionary size of
+.RI "2^" n
+or
+.RI "2^" n " + 2^(" n "\-1)."
+This is to decrease false positives when detecting
+.B .lzma
+files.
+.PP
+These limitations shouldn't be a problem in practice,
+since practically all
+.B .lzma
+files have been compressed with settings that liblzma will accept.
+.
+.SS "Trailing garbage"
+When decompressing,
+LZMA Utils silently ignore everything after the first
+.B .lzma
+stream.
+In most situations, this is a bug.
+This also means that LZMA Utils
+don't support decompressing concatenated
+.B .lzma
+files.
+.PP
+If there is data left after the first
+.B .lzma
+stream,
+.B xz
+considers the file to be corrupt unless
+.B \-\-single\-stream
+was used.
+This may break obscure scripts which have
+assumed that trailing garbage is ignored.
+.
+.SH NOTES
+.
+.SS "Compressed output may vary"
+The exact compressed output produced from
+the same uncompressed input file
+may vary between XZ Utils versions even if
+compression options are identical.
+This is because the encoder can be improved
+(faster or better compression)
+without affecting the file format.
+The output can vary even between different
+builds of the same XZ Utils version,
+if different build options are used.
+.PP
+The above means that once
+.B \-\-rsyncable
+has been implemented,
+the resulting files won't necessarily be rsyncable
+unless both old and new files have been compressed
+with the same xz version.
+This problem can be fixed if a part of the encoder
+implementation is frozen to keep rsyncable output
+stable across xz versions.
+.
+.SS "Embedded .xz decompressors"
+Embedded
+.B .xz
+decompressor implementations like XZ Embedded don't necessarily
+support files created with integrity
+.I check
+types other than
+.B none
+and
+.BR crc32 .
+Since the default is
+.BR \-\-check=crc64 ,
+you must use
+.B \-\-check=none
+or
+.B \-\-check=crc32
+when creating files for embedded systems.
+.PP
+Outside embedded systems, all
+.B .xz
+format decompressors support all the
+.I check
+types, or at least are able to decompress
+the file without verifying the
+integrity check if the particular
+.I check
+is not supported.
+.PP
+XZ Embedded supports BCJ filters,
+but only with the default start offset.

+.RE
+.PP
+If you know that a file requires
+somewhat big dictionary (for example, 32\ MiB) to compress well,
+but you want to compress it quicker than
+.B "xz \-8"
+would do, a preset with a low CompCPU value (for example, 1)
+can be modified to use a bigger dictionary:
+.RS
+.PP
+.nf
+.ft CW
+xz \-\-lzma2=preset=1,dict=32MiB foo.tar
+.ft R
+.fi
+.RE
+.PP
+With certain files, the above command may be faster than
+.B "xz \-6"
+while compressing significantly better.
+However, it must be emphasized that only some files benefit from
+a big dictionary while keeping the CompCPU value low.
+The most obvious situation,
+where a big dictionary can help a lot,
+is an archive containing very similar files
+of at least a few megabytes each.
+The dictionary size has to be significantly bigger
+than any individual file to allow LZMA2 to take
+full advantage of the similarities between consecutive files.
+.PP
+If very high compressor and decompressor memory usage is fine,
+and the file being compressed is
+at least several hundred megabytes, it may be useful
+to use an even bigger dictionary than the 64 MiB that
+.B "xz \-9"
+would use:
+.RS
+.PP
+.nf
+.ft CW
+xz \-vv \-\-lzma2=dict=192MiB big_foo.tar
+.ft R
+.fi
+.RE
+.PP
+Using
+.B \-vv
+.RB ( "\-\-verbose \-\-verbose" )
+like in the above example can be useful
+to see the memory requirements
+of the compressor and decompressor.
+Remember that using a dictionary bigger than
+the size of the uncompressed file is waste of memory,
+so the above command isn't useful for small files.
+.PP
+Sometimes the compression time doesn't matter,
+but the decompressor memory usage has to be kept low, for example,
+to make it possible to decompress the file on an embedded system.
+The following command uses
+.B \-6e
+.RB ( "\-6 \-\-extreme" )
+as a base and sets the dictionary to only 64\ KiB.
+The resulting file can be decompressed with XZ Embedded
+(that's why there is
+.BR \-\-check=crc32 )

+If you want to squeeze out as many bytes as possible,

+.RI ( pb )
+can sometimes help.
+Adjusting the number of literal position bits
+.RI ( lp )
+might help too, but usually
+.I lc
+and
+.I pb
+are more important.
+For example, a source code archive contains mostly US-ASCII text,

+Using another filter together with LZMA2 can improve

+using the x86 BCJ filter:
+.RS
+.PP
+.nf
+.ft CW
+xz \-\-x86 \-\-lzma2 libfoo.so
+.ft R
+.fi
+.RE
+.PP
+Note that the order of the filter options is significant.
+If
+.B \-\-x86
+is specified after
+.BR \-\-lzma2 ,
+.B xz
+will give an error,
+because there cannot be any filter after LZMA2,
+and also because the x86 BCJ filter cannot be used
+as the last filter in the chain.
+.PP
+The Delta filter together with LZMA2
+can give good results with bitmap images.
+It should usually beat PNG,
+which has a few more advanced filters than simple
+delta but uses Deflate for the actual compression.
+.PP
+The image has to be saved in uncompressed format,
+for example, as uncompressed TIFF.
+The distance parameter of the Delta filter is set
+to match the number of bytes per pixel in the image.
+For example, 24-bit RGB bitmap needs
+.BR dist=3 ,
+and it is also good to pass
+.B pb=0
+to LZMA2 to accommodate the three-byte alignment:
+.RS
+.PP
+.nf
+.ft CW
+xz \-\-delta=dist=3 \-\-lzma2=pb=0 foo.tiff
+.ft R
+.fi
+.RE
+.PP
+If multiple images have been put into a single archive (for example,

+the Delta filter will work on that too as long as all images
+have the same number of bytes per pixel.

+.SH NAME
+xzdec, lzmadec \- Small .xz and .lzma decompressors
+.SH SYNOPSIS
+.B xzdec
+.RI [ option... ]
+.RI [ file... ]
+.br
+.B lzmadec
+.RI [ option... ]
+.RI [ file... ]
+.SH DESCRIPTION
+.B xzdec
+is a liblzma-based decompression-only tool for
+.B .xz
+(and only
+.BR .xz )
+files.
+.B xzdec
+is intended to work as a drop-in replacement for
+.BR xz (1)
+in the most common situations where a script
+has been written to use
+.B "xz \-\-decompress \-\-stdout"
+(and possibly a few other commonly used options) to decompress
+.B .xz
+files.
+.B lzmadec
+is identical to
+.B xzdec
+except that
+.B lzmadec
+supports
+.B .lzma
+files instead of
+.B .xz
+files.
+.PP
+To reduce the size of the executable,
+.B xzdec
+doesn't support multithreading or localization,
+and doesn't read options from
+.B XZ_DEFAULTS
+and
+.B XZ_OPT
+environment variables.
+.B xzdec
+doesn't support displaying intermediate progress information: sending
+.B SIGINFO
+to
+.B xzdec
+does nothing, but sending
+.B SIGUSR1
+terminates the process instead of displaying progress information.
+.SH OPTIONS
+.TP
+.BR \-d ", " \-\-decompress ", " \-\-uncompress
+Ignored for
+.BR xz (1)
+compatibility.
+.B xzdec
+supports only decompression.
+.TP
+.BR \-k ", " \-\-keep
+Ignored for
+.BR xz (1)
+compatibility.
+.B xzdec
+never creates or removes any files.
+.TP
+.BR \-c ", " \-\-stdout ", " \-\-to-stdout
+Ignored for
+.BR xz (1)
+compatibility.
+.B xzdec
+always writes the decompressed data to standard output.
+.TP
+.BR \-q ", " \-\-quiet
+Specifying this once does nothing since
+.B xzdec
+never displays any warnings or notices.
+Specify this twice to suppress errors.
+.TP
+.BR \-Q ", " \-\-no-warn
+Ignored for
+.BR xz (1)
+compatibility.
+.B xzdec
+never uses the exit status 2.
+.TP
+.BR \-h ", " \-\-help
+Display a help message and exit successfully.
+.TP
+.BR \-V ", " \-\-version
+Display the version number of
+.B xzdec
+and liblzma.
+.SH "EXIT STATUS"
+.TP
+.B 0
+All was good.
+.TP
+.B 1
+An error occurred.
+.PP
+.B xzdec
+doesn't have any warning messages like
+.BR xz (1)
+has, thus the exit status 2 is not used by
+.BR xzdec .
+.SH NOTES
+Use
+.BR xz (1)
+instead of
+.B xzdec
+or
+.B lzmadec
+for normal everyday use.
+.B xzdec
+or
+.B lzmadec
+are meant only for situations where it is important to have
+a smaller decompressor than the full-featured
+.BR xz (1).
+.PP
+.B xzdec
+and
+.B lzmadec
+are not really that small.
+The size can be reduced further by dropping
+features from liblzma at compile time,
+but that shouldn't usually be done for executables distributed
+in typical non-embedded operating system distributions.
+If you need a truly small
+.B .xz
+decompressor, consider using XZ Embedded.
+.SH "SEE ALSO"

+.xz and .lzma Test Files
+------------------------
+
+0. Introduction
+
+    This directory contains bunch of files to test handling of .xz,
+    .lzma (LZMA_Alone), and .lz (lzip) files in decoder implementations.
+    Many of the files have been created by hand with a hex editor, thus
+    there is no better "source code" than the files themselves. All the
+    test files and this README have been put into the public domain.
+
+
+1. File Types
+
+    Good files (good-*) must decode successfully without requiring
+    a lot of CPU time or RAM.
+
+    Unsupported files (unsupported-*) are good files, but headers
+    indicate features not supported by the current file format
+    specification.
+
+    Bad files (bad-*) must cause the decoder to give an error. Like
+    with the good files, these files must not require a lot of CPU
+    time or RAM before they get detected to be broken.
+
+
+2. Descriptions of Individual .xz Files
+
+2.1. Good Files
+
+    good-0-empty.xz has one Stream with no Blocks.
+
+    good-0pad-empty.xz has one Stream with no Blocks followed by
+    four-byte Stream Padding.
+
+    good-0cat-empty.xz has two zero-Block Streams concatenated without
+    Stream Padding.
+
+    good-0catpad-empty.xz has two zero-Block Streams concatenated with
+    four-byte Stream Padding between the Streams.
+
+    good-1-check-none.xz has one Stream with one Block with two
+    uncompressed LZMA2 chunks and no integrity check.
+
+    good-1-check-crc32.xz has one Stream with one Block with two
+    uncompressed LZMA2 chunks and CRC32 check.
+
+    good-1-check-crc64.xz is like good-1-check-crc32.xz but with CRC64.
+
+    good-1-check-sha256.xz is like good-1-check-crc32.xz but with
+    SHA256.
+
+    good-2-lzma2.xz has one Stream with two Blocks with one uncompressed
+    LZMA2 chunk in each Block.
+
+    good-1-block_header-1.xz has both Compressed Size and Uncompressed
+    Size in the Block Header. This has also four extra bytes of Header
+    Padding.
+
+    good-1-block_header-2.xz has known Compressed Size.
+
+    good-1-block_header-3.xz has known Uncompressed Size.
+
+    good-1-delta-lzma2.tiff.xz is an image file that compresses
+    better with Delta+LZMA2 than with plain LZMA2.
+
+    good-1-x86-lzma2.xz uses the x86 filter (BCJ) and LZMA2. The
+    uncompressed file is compress_prepared_bcj_x86 found from the tests
+    directory.
+
+    good-1-sparc-lzma2.xz uses the SPARC filter and LZMA2. The
+    uncompressed file is compress_prepared_bcj_sparc found from the tests
+    directory.
+
+    good-1-arm64-lzma2-1.xz uses the ARM64 filter and LZMA2. The
+    uncompressed data is constructed so that it tests integer
+    wrap around and sign extension.
+
+    good-1-arm64-lzma2-2.xz is like good-1-arm64-lzma2-1.xz but with
+    non-zero start offset. XZ Embedded doesn't support this file.
+
+    good-1-lzma2-1.xz has two LZMA2 chunks, of which the second sets
+    new properties.
+
+    good-1-lzma2-2.xz has two LZMA2 chunks, of which the second resets
+    the state without specifying new properties.
+
+    good-1-lzma2-3.xz has two LZMA2 chunks, of which the first is
+    uncompressed and the second is LZMA. The first chunk resets dictionary
+    and the second sets new properties.
+
+    good-1-lzma2-4.xz has three LZMA2 chunks: First is LZMA, second is
+    uncompressed with dictionary reset, and third is LZMA with new
+    properties but without dictionary reset.
+
+    good-1-lzma2-5.xz has an empty LZMA2 stream with only the end of
+    payload marker. XZ Utils 5.0.1 and older incorrectly see this file
+    as corrupt.
+
+    good-1-3delta-lzma2.xz has three Delta filters and LZMA2.
+
+    good-1-empty-bcj-lzma2.xz has an empty Block that uses PowerPC BCJ
+    and LZMA2. liblzma from XZ Utils 5.0.1 and older may incorrectly
+    return LZMA_BUF_ERROR in some cases. See commit message
+    d8db706acb8316f9861abd432cfbe001dd6d0c5c for the details.
+
+
+2.2. Unsupported Files
+
+    unsupported-check.xz uses Check ID 0x02 which isn't supported by
+    the current version of the file format. It is implementation-defined
+    how this file handled (it may reject it, or decode it possibly with
+    a warning).
+
+    unsupported-block_header.xz has a non-null byte in Header Padding,
+    which may indicate presence of a new unsupported field.
+
+    unsupported-filter_flags-1.xz has unsupported Filter ID 0x7F.
+
+    unsupported-filter_flags-2.xz specifies only Delta filter in the
+    List of Filter Flags, but Delta isn't allowed as the last filter in
+    the chain. It could be a little more correct to detect this file as
+    corrupt instead of unsupported, but saying it is unsupported is
+    simpler in case of liblzma.
+
+    unsupported-filter_flags-3.xz specifies two LZMA2 filters in the
+    List of Filter Flags. LZMA2 is allowed only as the last filter in the
+    chain. It could be a little more correct to detect this file as
+    corrupt instead of unsupported, but saying it is unsupported is
+    simpler in case of liblzma.
+
+
+2.3. Bad Files
+
+    bad-0pad-empty.xz has one Stream with no Blocks followed by
+    five-byte Stream Padding. Stream Padding must be a multiple of four
+    bytes, thus this file is corrupt.
+
+    bad-0catpad-empty.xz has two zero-Block Streams concatenated with
+    five-byte Stream Padding between the Streams.
+
+    bad-0cat-alone.xz is good-0-empty.xz concatenated with an empty
+    LZMA_Alone file.
+
+    bad-0cat-header_magic.xz is good-0cat-empty.xz but with one byte
+    wrong in the Header Magic Bytes field of the second Stream. liblzma
+    gives LZMA_DATA_ERROR for this. (LZMA_FORMAT_ERROR is used only if
+    the first Stream of a file has invalid Header Magic Bytes.)
+
+    bad-0-header_magic.xz is good-0-empty.xz but with one byte wrong
+    in the Header Magic Bytes field. liblzma gives LZMA_FORMAT_ERROR for
+    this.
+
+    bad-0-footer_magic.xz is good-0-empty.xz but with one byte wrong
+    in the Footer Magic Bytes field. liblzma gives LZMA_DATA_ERROR for
+    this.
+
+    bad-0-empty-truncated.xz is good-0-empty.xz without the last byte
+    of the file.
+
+    bad-0-nonempty_index.xz has no Blocks but Index claims that there is
+    one Block.
+
+    bad-0-backward_size.xz has wrong Backward Size in Stream Footer.
+
+    bad-1-stream_flags-1.xz has different Stream Flags in Stream Header
+    and Stream Footer.
+
+    bad-1-stream_flags-2.xz has wrong CRC32 in Stream Header.
+
+    bad-1-stream_flags-3.xz has wrong CRC32 in Stream Footer.
+
+    bad-1-vli-1.xz has two-byte variable-length integer in the
+    Uncompressed Size field in Block Header while one-byte would be enough
+    for that value. It's important that the file gets rejected due to too
+    big integer encoding instead of due to Uncompressed Size not matching
+    the value stored in the Block Header. That is, the decoder must not
+    try to decode the Compressed Data field.
+
+    bad-1-vli-2.xz has ten-byte variable-length integer as Uncompressed
+    Size in Block Header. It's important that the file gets rejected due
+    to too big integer encoding instead of due to Uncompressed Size not
+    matching the value stored in the Block Header. That is, the decoder
+    must not try to decode the Compressed Data field.
+
+    bad-1-block_header-1.xz has Block Header that ends in the middle of
+    the Filter Flags field.
+
+    bad-1-block_header-2.xz has Block Header that has Compressed Size and
+    Uncompressed Size but no List of Filter Flags field.
+
+    bad-1-block_header-3.xz has wrong CRC32 in Block Header.
+
+    bad-1-block_header-4.xz has too big Compressed Size in Block Header
+    (2^63 - 1 bytes while maximum is a little less, because the whole
+    Block must stay smaller than 2^63). It's important that the file
+    gets rejected due to invalid Compressed Size value; the decoder
+    must not try decoding the Compressed Data field.
+
+    bad-1-block_header-5.xz has zero as Compressed Size in Block Header.
+
+    bad-1-block_header-6.xz has corrupt Block Header which may crash
+    xz -lvv in XZ Utils 5.0.3 and earlier. It was fixed in the commit
+    c0297445064951807803457dca1611b3c47e7f0f.
+
+    bad-2-index-1.xz has wrong Unpadded Sizes in Index.
+
+    bad-2-index-2.xz has wrong Uncompressed Sizes in Index.
+
+    bad-2-index-3.xz has non-null byte in Index Padding.
+
+    bad-2-index-4.xz wrong CRC32 in Index.
+
+    bad-2-index-5.xz has zero as Unpadded Size. It is important that the
+    file gets rejected specifically due to Unpadded Size having an invalid
+    value.
+
+    bad-3-index-uncomp-overflow.xz has Index whose Uncompressed Size
+    fields have huge values whose sum exceeds the maximum allowed size
+    of 2^63 - 1 bytes. In this file the sum is exactly 2^64.
+    lzma_index_append() in liblzma <= 5.2.6 lacks the integer overflow
+    check for the uncompressed size and thus doesn't catch the error
+    when decoding the Index field in this file. This makes "xz -l"
+    not detect the error and will display 0 as the uncompressed size.
+    Note that regular decompression isn't affected by this bug because
+    it uses lzma_index_hash_append() instead.
+
+    bad-2-compressed_data_padding.xz has non-null byte in the padding of
+    the Compressed Data field of the first Block.
+
+    bad-1-check-crc32.xz has wrong Check (CRC32).
+
+    bad-1-check-crc32-2.xz has Compressed Size and Uncompressed Size in
+    Block Header but wrong Check (CRC32) in the actual data. This file
+    differs by one byte from good-1-block_header-1.xz: the last byte of
+    the Check field is wrong. This file is useful for testing error
+    detection in the threaded decoder when a worker thread is configured
+    to pass input one byte at a time to the Block decoder.
+
+    bad-1-check-crc64.xz has wrong Check (CRC64).
+
+    bad-1-check-sha256.xz has wrong Check (SHA-256).
+
+    bad-1-lzma2-1.xz has LZMA2 stream whose first chunk (uncompressed)
+    doesn't reset the dictionary.
+
+    bad-1-lzma2-2.xz has two LZMA2 chunks, of which the second chunk
+    indicates dictionary reset, but the LZMA compressed data tries to
+    repeat data from the previous chunk.
+
+    bad-1-lzma2-3.xz sets new invalid properties (lc=8, lp=0, pb=0) in
+    the middle of Block.
+
+    bad-1-lzma2-4.xz has two LZMA2 chunks, of which the first is
+    uncompressed and the second is LZMA. The first chunk resets dictionary
+    as it should, but the second chunk tries to reset state without
+    specifying properties for LZMA.
+
+    bad-1-lzma2-5.xz is like bad-1-lzma2-4.xz but doesn't try to reset
+    anything in the header of the second chunk.
+
+    bad-1-lzma2-6.xz has reserved LZMA2 control byte value (0x03).
+
+    bad-1-lzma2-7.xz has EOPM at LZMA level.
+
+    bad-1-lzma2-8.xz is like good-1-lzma2-4.xz but doesn't set new
+    properties in the third LZMA2 chunk.
+
+    bad-1-lzma2-9.xz has LZMA2 stream that is truncated at the end of
+    a LZMA2 chunk (no end marker). The uncompressed size of the partial
+    LZMA2 stream exceeds the value stored in the Block Header.
+
+    bad-1-lzma2-10.xz has LZMA2 stream that, from point of view of a
+    LZMA2 decoder, extends past the end of Block (and even the end of
+    the file). Uncompressed Size in Block Header is bigger than the
+    invalid LZMA2 stream may produce (even if a decoder reads until
+    the end of the file). The Check type is None to nullify certain
+    simple size-based sanity checks in a Block decoder.
+
+    bad-1-lzma2-11.xz has LZMA2 stream that lacks the end of
+    payload marker. When Compressed Size bytes have been decoded,
+    Uncompressed Size bytes of output will have been produced but
+    the LZMA2 decoder doesn't indicate end of stream.
+
+
+3. Descriptions of Individual .lzma Files
+
+3.1. Good Files
+
+    good-unknown_size-with_eopm.lzma has unknown size in the header
+    and end of payload marker at the end.
+
+    good-known_size-without_eopm.lzma has a known size in the header
+    and no end of payload marker at the end.
+
+    good-known_size-with_eopm.lzma has a known size in the header
+    and end of payload marker at the end. XZ Utils 5.2.5 and older
+    will give an error at the end of the file after producing the
+    correct uncompressed output.
+
+
+3.2. Bad Files
+
+    bad-unknown_size-without_eopm.lzma has unknown size in the header
+    but no end of payload marker at the end. This file might be seen
+    by a decoder as if it were truncated.
+
+    bad-too_big_size-with_eopm.lzma has too big uncompressed size in
+    the header and the end of payload marker will be detected before
+    the specified number of bytes have been decoded.
+
+    bad-too_small_size-without_eopm-1.lzma has too small uncompressed
+    size in the header. The decoder will look for end of payload marker
+    but instead find a literal that would produce more output.
+
+    bad-too_small_size-without_eopm-2.lzma is like -1 above but instead
+    of a literal the problem occurs with a short repeated match.
+
+    bad-too_small_size-without_eopm-3.lzma is like -1 above but instead
+    of a literal the problem occurs in the middle of a match.
+
+
+4. Descriptions of Individual .lz (lzip) Files
+
+4.1. Good Files
+
+    good-1-v0.lz contains a single version 0 member. lzip 1.17 and
+    *older* can decompress this; support for version 0 was removed
+    in lzip 1.18.
+
+    good-1-v0-trailing-1.lz is like good-1-v0.lz but contains
+    trailing data that the decompressor must ignore.
+
+    good-1-v1.lz contains a single version 1 member. lzip 1.3 and
+    newer can decompress this.
+
+    good-1-v1-trailing-1.lz is like good-1-v1.lz but contains
+    trailing data that the decompressor must ignore.
+
+    good-1-v1-trailing-2.lz is like good-1-v1.lz but contains
+    trailing data whose first three bytes match the .lz magic bytes.
+    With lzip >= 1.20 this file results in an error unless one uses
+    the command line option --loose-trailing. lzip 1.3 to 1.19 decode
+    this file successfully by default. XZ Utils uses the old behavior
+    because it allows lzma_code() to stop at the first byte of the
+    trailing data as long as the first byte isn't 0x4C (L in US-ASCII);
+    otherwise the first 1-3 bytes that equal to the magic bytes are
+    consumed and lost in lzma_code(), and this is visible in xz too:
+
+        $ ( xz -dc ; cat ) < good-1-v1-trailing-2.lz
+        Hello
+        World!
+        Trailing garbage
+
+        $ ( xz -dc --single-stream ; cat ) < good-1-v1-trailing-2.lz
+        Hello
+        World!
+        LZITrailing garbage
+
+    good-2-v0-v1.lz contains two members of which the first is
+    version 0 and the second version 1. lzip versions 1.3 to 1.17
+    (inclusive) can decompress this.
+
+    good-2-v1-v0.lz contains two members of which the first is
+    version 1 and the second version 0. lzip versions 1.3 to 1.17
+    (inclusive) can decompress this.
+
+    good-2-v1-v1.lz contains two version 1 members. lzip versions 1.3
+    and newer can decompress this.
+
+
+4.2. Unsupported Files
+
+    unsupported-1-v234.lz is like good-1-v1.lz except the version
+    field has been set to 234 (0xEA) which, as of writing, isn't
+    defined or supported by any .lz implementation.
+
+
+4.3. Bad Files
+
+    bad-1-v1-magic-1.lz is like good-1-v1.lz but the first magic byte
+    is wrong.
+
+    bad-1-v1-magic-2.lz is like good-1-v1.lz but the last (fourth)
+    magic byte is wrong.
+
+    bad-1-v1-dict-1.lz has too low value in the dictionary size field.
+
+    bad-1-v1-dict-2.lz has too high value in the dictionary size field.
+
+    bad-1-v1-crc32.lz has wrong CRC32 value.
+
+    bad-1-v0-uncomp-size.lz is version 0 format with incorrect value
+    in the uncompressed size field.
+
+    bad-1-v1-uncomp-size.lz is version 1 format with incorrect value
+    in the uncompressed size field.
+
+    bad-1-v1-member-size.lz has incorrect value in the member size
+    field.
+
+    bad-1-v1-trailing-magic.lz has the four .lz magic bytes as trailing
+    data. This should be detected as a truncated file and thus result
+    in an error. That is, the last four bytes of the file should not be
+    ignored as trailing garbage. lzip >= 1.18 matches this behavior
+    while older versions ignore the last four bytes and don't indicate
+    an error.

+///////////////////////////////////////////////////////////////////////////////
+//
+/// \file       tuktest.h
+/// \brief      Helper macros for writing simple test programs
+/// \version    2023-01-08
+///
+/// Some inspiration was taken from STest by Keith Nicholas.
+///
+/// This is standard C99/C11 only and thus should be fairly portable
+/// outside POSIX systems too.
+///
+/// This supports putting multiple tests in a single test program
+/// although it is perfectly fine to have only one test per program.
+/// Each test can produce one of these results:
+///   - Pass
+///   - Fail
+///   - Skip
+///   - Hard error (the remaining tests, if any, are not run)
+///
+/// By default this produces an exit status that is compatible with
+/// Automake and Meson, and mostly compatible with CMake.[1]
+/// If a test program contains multiple tests, only one exit code can
+/// be returned. Of the following, the first match is used:
+///   - 99 if any test returned a hard error
+///   - stdlib.h's EXIT_FAILURE if at least one test failed
+///   - 77 if at least one test was skipped or no tests were run at all
+///   - stdlib.h's EXIT_SUCCESS (0 on POSIX); that is, if none of the above
+///     are true then there was at least one test to run and none of them
+///     failed, was skipped, or returned a hard error.
+///
+/// A summary of tests being run and their results are printed to stdout.
+/// If you want ANSI coloring for the output, #define TUKTEST_COLOR.
+/// If you only want output when something goes wrong, #define TUKTEST_QUIET.
+///
+/// The downside of the above mapping is that it cannot indicate if
+/// some tests were skipped and some passed. If that is likely to
+/// happen it may be better to split into multiple test programs (one
+/// test per program) or use the TAP mode described below.
+///
+/// By using #define TUKTEST_TAP before #including this file the
+/// output will be Test Anything Protocol (TAP) version 12 compatible
+/// and the exit status will always be EXIT_SUCCESS. This can be easily
+/// used with Automake via its tap-driver.sh. Meson supports TAP natively.
+/// TAP's todo-directive isn't supported for now, mostly because it's not
+/// trivially convertible to the exit-status reporting method.
+///
+/// If TUKTEST_TAP is used, TUKTEST_QUIET and TUKTEST_COLOR are ignored.
+///
+/// The main() function may look like this (remember to include config.h
+/// or such files too if needed!):
+///
+///     #include "tuktest.h"
+///
+///     int main(int argc, char **argv)
+///     {
+///         tuktest_start(argc, argv);
+///
+///         if (!is_package_foo_available())
+///             tuktest_early_skip("Optional package foo is not available");
+///
+///         if (!do_common_initializations())
+///             tuktest_error("Error during common initializations");
+///
+///         tuktest_run(testfunc1);
+///         tuktest_run(testfunc2);
+///
+///         return tuktest_end();
+///     }
+///
+/// Using exit(tuktest_end()) as a pair to tuktest_start() is OK too.
+///
+/// Each test function called via tuktest_run() should be of type
+/// "void testfunc1(void)". The test functions should use the
+/// various assert_CONDITION() macros. The current test stops if
+/// an assertion fails (this is implemented with setjmp/longjmp).
+/// Execution continues from the next test unless the failure was
+/// due to assert_error() (indicating a hard error) which makes
+/// the program exit() without running any remaining tests.
+///
+/// Search for "define assert" in this file to find the explanations
+/// of the available assertion macros.
+///
+/// IMPORTANT:
+///
+///   - The assert_CONDITION() macros may only be used by code that is
+///     called via tuktest_run()! This includes the function named in
+///     the tuktest_run() call and functions called further from there.
+///     (The assert_CONDITION() macros depend on setup code in tuktest_run()
+///     and other use results in undefined behavior.)
+///
+///   - tuktest_start(), tuktest_early_skip, tuktest_run(), and tuktest_end()
+///     must not be used in the tests called via tuktest_run()! (tuktest_end()
+///     is called more freely internally by this file but such use isn't part
+///     of the API.)
+///
+///   - tuktest_error(), tuktest_malloc(), tuktest_free(),
+///     tuktest_file_from_srcdir(), and tuktest_file_from_builddir()
+///     can be used everywhere after tuktest_start() has been called.
+///     (In tests running under tuktest_run(), assert_error() can be used
+///     instead of tuktest_error() when a hard error occurs.)
+///
+///   - Everything else is for internal use only.
+///

+Building XZ Utils with Microsoft Visual Studio
+==============================================
+
+Introduction
+------------
+
+    MSVC 2013 update 2 and later have enough C99 support to build
+    liblzma from XZ Utils 5.2.0 and later without modifications.
+    Older MSVC versions would require a large number of changes to
+    the XZ Utils code and thus the old MSVC versions aren't supported.
+
+    As of 2015-06-19, some work has been done to get xz.exe and other
+    command line tools built with MSVC, but it's not complete enough
+    to be included in XZ Utils.
+
+
+Building
+--------
+
+    It is recommended to use CMake to generate build files for MSVC.
+    The project files in vs201x directories will be removed in the
+    future (5.4.x releases will include them still).
+
+    Descriptions of the files in the vs201x directories:
+
+        config.h              liblzma configuration #defines for MSVC.
+        liblzma.vcxproj       This builds static liblzma.
+        liblzma_dll.vcxproj   This builds liblzma.dll.
+        xz_win.sln            Solution using the above project files.
+
+    The projects have x86 and x86-64 platform configurations, as well
+    as a Debug, Release, and ReleaseMT configuration -- MT is the
+    compiler switch to link to the CRT statically, so it will not
+    have any other DLL dependencies.
+
+    The VS2017 project files don't set <WindowsTargetPlatformVersion>.
+    This means that you may need to either install Windows SDK 8.1 or
+    you may need to set the target platform version before building.
+
+    Currently no test programs are built or run under MSVC from the
+    project files. CMake-based builds include tests too.
+
+
+Notes
+-----
+
+    liblzma API headers declare the functions with __declspec(dllimport)
+    by default. To avoid this when using static liblzma from your code,
+    #define LZMA_API_STATIC before #including <lzma.h>.
+
+    MSVC gives a bunch of compiler warnings. Some warnings are specific
+    to 32-bit or 64-bit build and some appear for both builds. These
+    are known and shouldn't be a problem. Some of them will probably
+    be fixed in the future.

+
+Building XZ Utils on Windows
+============================
+
+Introduction
+------------
+
+    This document explains shortly where to get and how to install the
+    build tools that are needed to build XZ Utils on Windows. The final
+    binary package will be standalone in sense that it will depend only
+    on DLLs that are included in all Windows installations.
+
+    These instructions don't apply to Cygwin. XZ Utils can be built under
+    Cygwin in the same way as many other packages.
+
+    These instructions don't apply to MinGW and MSYS developers either,
+    who may want to package XZ Utils for MinGW or MSYS distributions.
+    You know who you are, and will probably use quite different configure
+    options etc. than what is described here.
+
+
+Installing the toolchain(s)
+---------------------------
+
+    Some of the following is needed:
+      - MSYS is always needed to use the GNU Autotools based build system.
+      - MinGW builds 32-bit x86 binaries.
+      - 32-bit MinGW-w64 (I call it MingW-w32 here) builds 32-bit x86
+        executables too.
+      - MinGW-w64 builds 64-bit x86-64 binaries.
+
+    So you need to pick between MinGW and MinGW-w32 when building
+    32-bit version. You don't need both.
+
+    You might find 7-Zip <https://7-zip.org/> handy when extracting
+    some files. The ready-made build script build.bash will also use
+    7-Zip to create the distributable .zip and .7z files.
+
+    I used the following directory structure but you can use whatever
+    you want. Just note that I will use these in my examples. Each of
+    these should have a subdirectory "bin":
+
+        C:\devel\tools\msys
+        C:\devel\tools\mingw
+        C:\devel\tools\mingw-w32
+        C:\devel\tools\mingw-w64
+
+
+Installing MSYS
+
+    You can download MSYS from MinGW's Sourceforge page:
+
+        https://sourceforge.net/projects/mingw/files/MSYS/Base/msys-core/
+
+    I recommend using MSYS 1.0.11 (MSYS-1.0.11.exe or
+    msysCORE-1.0.11-bin.tar.gz) because that package includes all the
+    required tools. At least some of the later versions include only
+    a subset and thus you would need to download the rest separately.
+    The old version will work fine for building XZ Utils.
+
+    You can use either the .exe or .tar.gz package. I prefer .tar.gz,
+    because it can be extracted into any directory and later removed
+    without worrying about uninstallers.
+
+
+Installing MinGW
+
+    NOTE: This section may be outdated. I haven't tried MinGW recently.
+
+    You can download the required packages from MinGW's Sourceforge page:
+
+        https://sourceforge.net/projects/mingw/files/
+
+    These version numbers were the latest when I wrote this document, but
+    you probably should pick the latest versions:
+
+        MinGW Runtime -> mingwrt-3.17-mingw32-dev.tar.gz
+        MinGW API for MS-Windows -> w32api-3.14-mingw32-dev.tar.gz
+        GNU Binutils -> binutils-2.20-1-bin.tar.gz
+        GCC Version 4 -> gcc-full-4.4.0-mingw32-bin-2.tar.lzma
+
+    The full GCC package is quite big, but if you want a smaller
+    download, you will need to download more than one file, so I'm
+    using the full package in this document for simplicity.
+
+    Extract the packages in the above order, possibly overwriting files
+    from packages that were extracted earlier.
+
+
+Installing MinGW-w32 or MinGW-w64
+
+    I used the packages from Mingw-builds project. With that it is
+    enough to pick one .7z file for 32-bit and another for 64-bit
+    toolchain. For XZ Utils 5.2.0 I used the packages from these
+    directories:
+
+        https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/mingw-builds/4.9.2/threads-win32/sjlj/
+
+        https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/4.9.2/threads-win32/sjlj/
+
+    If you install both MinGW-w32 and MinGW-w64, remember to extract
+    them into different directories. build.bash looks at
+    C:\devel\tools\mingw-w32 and C:\devel\tools\mingw-w64 by default.
+
+
+Building XZ Utils
+-----------------
+
+    Start MSYS by going to the directory C:\devel\tools\msys and running
+    msys.bat there (double-click or use command prompt). It will start
+    at "home" directory, which is C:\devel\tools\msys\home\YourUserName.
+
+    If you have xz-5.x.x.tar.gz in C:\devel, you should be able to build
+    it now with the following commands:
+
+        cd /c/devel
+        tar xzf xz-5.x.x.tar.gz
+        cd xz-5.x.x
+        bash windows/build.bash
+
+    If you used some other directory than C:\devel\tools for the build
+    tools, edit the variables near the beginning of build.bash first.
+
+    If you want to build manually, read the buildit() function in
+    build.bash. Look especially at the latter configure invocation.
+
+    Be patient. Running configure and other scripts used by the build
+    system is (very) slow under Windows.
+
+
+Using a snapshot from the Git repository
+
+    To use a snapshot, the build system files need to be generated with
+    autogen.sh or "autoreconf -fi" before trying to build using the
+    above build instructions. You can install the relevant extra packages
+    from MinGW or use Cygwin or use e.g. a GNU/Linux system to create a
+    source package with the required build system files.
+

+XZ Utils for Windows
+====================
+
+Introduction
+------------
+
+    This package includes command line tools (xz.exe and a few others)
+    and the liblzma compression library from XZ Utils. You can find the
+    latest version and full source code from <https://tukaani.org/xz/>.
+
+    The parts of the XZ Utils source code, that are relevant to this
+    binary package, are in the public domain. XZ Utils have been built
+    for this package with MinGW-w64 and linked statically against its
+    runtime libraries. See COPYING-Windows.txt for the copyright and
+    license information that applies to the MinGW-w64 runtime. You must
+    include it when redistributing these XZ Utils binaries.
+
+
+Package contents
+----------------
+
+    All executables and libraries in this package require msvcrt.dll.
+    It's included in all recent Windows versions. (On Windows 95 it
+    might be missing, but once you get it somewhere, the i686 binaries
+    should run even on Windows 95 if the processor is new enough.)
+
+    There is a SSE2 optimization in the compression code but this
+    version of XZ Utils doesn't include run-time processor detection.
+    This is why there is a separate i686-SSE2 version.
+
+    There is one directory for each type of executable and library files:
+
+        bin_i686        32-bit x86 (i686 and newer), Windows 95 and later
+        bin_i686-sse2   32-bit x86 (i686 with SSE2), Windows 98 and later
+        bin_x86-64      64-bit x86-64, Windows Vista and later
+
+    Each of the above directories have the following files:
+
+        *.exe       Command line tools. (It's useless to double-click
+                    these; use the command prompt instead.) These have
+                    been linked statically against liblzma, so they
+                    don't require liblzma.dll. Thus, you can copy e.g.
+                    xz.exe to a directory that is in PATH without copying
+                    any other files from this package.
+
+        liblzma.dll Shared version of the liblzma compression library.
+                    This file is mostly useful to developers, although
+                    some non-developers might use it to upgrade their
+                    copy of liblzma.
+
+        liblzma.a   Static version of the liblzma compression library.
+                    This file is useful only for developers.
+
+    The rest of the directories contain architecture-independent files:
+
+        doc         Documentation in the plain text (TXT) format. The
+                    manuals of the command line tools are provided also
+                    in the PDF format. liblzma.def is in this directory
+                    too.
+
+        include     C header files for liblzma. These should be
+                    compatible with most C and C++ compilers. If you
+                    have problems, try to fix it and send your fixes
+                    upstream, or at least report a bug, thanks.
+
+
+Linking against liblzma
+-----------------------
+
+MinGW
+
+    If you use MinGW, linking against liblzma.dll or liblzma.a should
+    be straightforward. You don't need an import library to link
+    against liblzma.dll, and for static linking, you don't need to
+    worry about the LZMA_API_STATIC macro.
+
+    Note that the MinGW distribution includes liblzma. If you are
+    building packages that will be part of the MinGW distribution, you
+    probably should use the version of liblzma shipped in MinGW instead
+    of this package.
+
+
+Microsoft Visual C++
+
+    To link against liblzma.dll, you need to create an import library
+    first. You need the "lib" command from MSVC and liblzma.def from
+    the "doc" directory of this package. Here is the command that works
+    on 32-bit x86:
+
+        lib /def:liblzma.def /out:liblzma.lib /machine:ix86
+
+    On x86-64, the /machine argument has to naturally be changed:
+
+        lib /def:liblzma.def /out:liblzma.lib /machine:x64
+
+    If you need to link statically against liblzma, you should build
+    liblzma with MSVC 2013 update 2 or later. Alternatively, if having
+    a decompressor is enough, consider using XZ Embedded or LZMA SDK.
+
+    When you plan to link against static liblzma, you need to tell
+    lzma.h to not use __declspec(dllimport) by defining the macro
+    LZMA_API_STATIC. You can do it either in the C/C++ code
+
+        #define LZMA_API_STATIC
+        #include <lzma.h>
+
+    or by adding it to compiler options.
+
+
+Other compilers
+
+    If you are using some other compiler, see its documentation how to
+    create an import library (if it is needed). If it is simple, I
+    might consider including the instructions here.
