+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.
