+1 Notes on the Free Translation Project
+***************************************
+
+Free software is going international!  The Free Translation Project is
+a way to get maintainers of free software, translators, and users all
+together, so that free software will gradually become able to speak many
+languages.  A few packages already provide translations for their
+messages.
+
+   If you found this `ABOUT-NLS' file inside a distribution, you may
+assume that the distributed package does use GNU `gettext' internally,
+itself available at your nearest GNU archive site.  But you do _not_
+need to install GNU `gettext' prior to configuring, installing or using
+this package with messages translated.
+
+   Installers will find here some useful hints.  These notes also
+explain how users should proceed for getting the programs to use the
+available translations.  They tell how people wanting to contribute and
+work on translations can contact the appropriate team.
+
+   When reporting bugs in the `intl/' directory or bugs which may be
+related to internationalization, you should tell about the version of
+`gettext' which is used.  The information can be found in the
+`intl/VERSION' file, in internationalized packages.
+
+1.1 Quick configuration advice
+==============================
+
+If you want to exploit the full power of internationalization, you
+should configure it using
+
+     ./configure --with-included-gettext
+
+to force usage of internationalizing routines provided within this
+package, despite the existence of internationalizing capabilities in the
+operating system where this package is being installed.  So far, only
+the `gettext' implementation in the GNU C library version 2 provides as
+many features (such as locale alias, message inheritance, automatic
+charset conversion or plural form handling) as the implementation here.
+It is also not possible to offer this additional functionality on top
+of a `catgets' implementation.  Future versions of GNU `gettext' will
+very likely convey even more functionality.  So it might be a good idea
+to change to GNU `gettext' as soon as possible.
+
+   So you need _not_ provide this option if you are using GNU libc 2 or
+you have installed a recent copy of the GNU gettext package with the
+included `libintl'.
+
+1.2 INSTALL Matters
+===================
+
+Some packages are "localizable" when properly installed; the programs
+they contain can be made to speak your own native language.  Most such
+packages use GNU `gettext'.  Other packages have their own ways to
+internationalization, predating GNU `gettext'.
+
+   By default, this package will be installed to allow translation of
+messages.  It will automatically detect whether the system already
+provides the GNU `gettext' functions.  If not, the included GNU
+`gettext' library will be used.  This library is wholly contained
+within this package, usually in the `intl/' subdirectory, so prior
+installation of the GNU `gettext' package is _not_ required.
+Installers may use special options at configuration time for changing
+the default behaviour.  The commands:
+
+     ./configure --with-included-gettext
+     ./configure --disable-nls
+
+will, respectively, bypass any pre-existing `gettext' to use the
+internationalizing routines provided within this package, or else,
+_totally_ disable translation of messages.
+
+   When you already have GNU `gettext' installed on your system and run
+configure without an option for your new package, `configure' will
+probably detect the previously built and installed `libintl.a' file and
+will decide to use this.  This might not be desirable.  You should use
+the more recent version of the GNU `gettext' library.  I.e. if the file
+`intl/VERSION' shows that the library which comes with this package is
+more recent, you should use
+
+     ./configure --with-included-gettext
+
+to prevent auto-detection.
+
+   The configuration process will not test for the `catgets' function
+and therefore it will not be used.  The reason is that even an
+emulation of `gettext' on top of `catgets' could not provide all the
+extensions of the GNU `gettext' library.
+
+   Internationalized packages usually have many `po/LL.po' files, where
+LL gives an ISO 639 two-letter code identifying the language.  Unless
+translations have been forbidden at `configure' time by using the
+`--disable-nls' switch, all available translations are installed
+together with the package.  However, the environment variable `LINGUAS'
+may be set, prior to configuration, to limit the installed set.
+`LINGUAS' should then contain a space separated list of two-letter
+codes, stating which languages are allowed.
+
+1.3 Using This Package
+======================
+
+As a user, if your language has been installed for this package, you
+only have to set the `LANG' environment variable to the appropriate
+`LL_CC' combination.  Here `LL' is an ISO 639 two-letter language code,
+and `CC' is an ISO 3166 two-letter country code.  For example, let's
+suppose that you speak German and live in Germany.  At the shell
+prompt, merely execute `setenv LANG de_DE' (in `csh'),
+`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
+This can be done from your `.login' or `.profile' file, once and for
+all.
+
+   You might think that the country code specification is redundant.
+But in fact, some languages have dialects in different countries.  For
+example, `de_AT' is used for Austria, and `pt_BR' for Brazil.  The
+country code serves to distinguish the dialects.
+
+   The locale naming convention of `LL_CC', with `LL' denoting the
+language and `CC' denoting the country, is the one use on systems based
+on GNU libc.  On other systems, some variations of this scheme are
+used, such as `LL' or `LL_CC.ENCODING'.  You can get the list of
+locales supported by your system for your language by running the
+command `locale -a | grep '^LL''.
+
+   Not all programs have translations for all languages.  By default, an
+English message is shown in place of a nonexistent translation.  If you
+understand other languages, you can set up a priority list of languages.
+This is done through a different environment variable, called
+`LANGUAGE'.  GNU `gettext' gives preference to `LANGUAGE' over `LANG'
+for the purpose of message handling, but you still need to have `LANG'
+set to the primary language; this is required by other parts of the
+system libraries.  For example, some Swedish users who would rather
+read translations in German than English for when Swedish is not
+available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
+
+   Special advice for Norwegian users: The language code for Norwegian
+bokma*l changed from `no' to `nb' recently (in 2003).  During the
+transition period, while some message catalogs for this language are
+installed under `nb' and some older ones under `no', it's recommended
+for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and
+older translations are used.
+
+   In the `LANGUAGE' environment variable, but not in the `LANG'
+environment variable, `LL_CC' combinations can be abbreviated as `LL'
+to denote the language's main dialect.  For example, `de' is equivalent
+to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
+(Portuguese as spoken in Portugal) in this context.
+
+1.4 Translating Teams
+=====================
+
+For the Free Translation Project to be a success, we need interested
+people who like their own language and write it well, and who are also
+able to synergize with other translators speaking the same language.
+Each translation team has its own mailing list.  The up-to-date list of
+teams can be found at the Free Translation Project's homepage,
+`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams"
+area.
+
+   If you'd like to volunteer to _work_ at translating messages, you
+should become a member of the translating team for your own language.
+The subscribing address is _not_ the same as the list itself, it has
+`-request' appended.  For example, speakers of Swedish can send a
+message to `sv-request@li.org', having this message body:
+
+     subscribe
+
+   Keep in mind that team members are expected to participate
+_actively_ in translations, or at solving translational difficulties,
+rather than merely lurking around.  If your team does not exist yet and
+you want to start one, or if you are unsure about what to do or how to
+get started, please write to `translation@iro.umontreal.ca' to reach the
+coordinator for all translator teams.
+
+   The English team is special.  It works at improving and uniformizing
+the terminology in use.  Proven linguistic skill are praised more than
+programming skill, here.
+
+1.5 Available Packages
+======================
+
+Languages are not equally supported in all packages.  The following
+matrix shows the current state of internationalization, as of July
+2006.  The matrix shows, in regard of each package, for which languages
+PO files have been submitted to translation coordination, with a
+translation percentage of at least 50%.

+   Some counters in the preceding matrix are higher than the number of
+visible blocks let us expect.  This is because a few extra PO files are
+used for implementing regional variants of languages, or language
+dialects.
+
+   For a PO file in the matrix above to be effective, the package to
+which it applies should also have been internationalized and
+distributed as such by its maintainer.  There might be an observable
+lag between the mere existence a PO file and its wide availability in a
+distribution.
+
+   If July 2006 seems to be old, you may fetch a more recent copy of
+this `ABOUT-NLS' file on most GNU archive sites.  The most up-to-date
+matrix with full percentage details can be found at
+`http://www.iro.umontreal.ca/contrib/po/HTML/matrix.html'.
+
+1.6 Using `gettext' in new packages
+===================================
+
+If you are writing a freely available program and want to
+internationalize it you are welcome to use GNU `gettext' in your
+package.  Of course you have to respect the GNU Library General Public
+License which covers the use of the GNU `gettext' library.  This means
+in particular that even non-free programs can use `libintl' as a shared
+library, whereas only free software can use `libintl' as a static
+library or use modified versions of `libintl'.
+
+   Once the sources are changed appropriately and the setup can handle
+the use of `gettext' the only thing missing are the translations.  The
+Free Translation Project is also available for packages which are not
+developed inside the GNU project.  Therefore the information given above
+applies also for every other Free Software Project.  Contact
+`translation@iro.umontreal.ca' to make the `.pot' files available to
+the translation teams.

+The following guidelines are intended to aid programmers in creating
+code that is consistent with the existing core plugins.
+
+The primary goals of these standards are internal consistency, and
+readability in a wide range of environments.
+
+
+1. C Language Programming
+
+All code should comply with the requirements of the Free Software
+Foundation Coding standards (which are currently available at
+http://www.gnu.org/prep/standards_toc.html). We also follow most of
+the FSF guidelines. Developers may suggest deviations from the FSF
+style recommendations, which will be considered by open discussion on
+the Monitoring Plugins devel mailing list. Any such deviations will
+apply to the entire code base to ensure consistency.
+
+Currently, the exceptions to FSF recommendations are roughly equivalent
+to GNU indent with invoked as 'indent -ts 2 -br'. Specifically, the
+exceptions are as follows:
+
+a) leading white space for a statement should be formatted as tabs,
+with one tab for each code indentation level.
+
+b) in statement continuation lines, format whitespace up to the column
+starting the statement as tabs, format the rest as spaces (this
+results in code that is legible regardless of tab-width setting).
+
+c) with the exception of the above, tabs should generally be avoided
+
+d) when tab width is 2 spaces, line-length should not exceed 80
+characters
+
+e) The opening brace of an if or while block is on the same line as
+the end of the conditional expression (the '-br' option).
+
+
+2. Perl Language Programming
+
+Taken from the O'Reilly book "Programming Perl" (3rd edition, pages 604-606) with
+modifications for clarity and to cohere with C coding standards.
+
+*) Always check the return code of system calls.
+
+a) Use tab indentation.
+
+b) Put space before the opening brace of a multiline block.
+
+c) A short block may be put on one line, including braces.
+
+d) Never omit the semicolon.
+
+e)  Surround most operators with space.
+
+	$x = 5;    # do this
+	$y=5;      # don't do this
+
+f) Surround a "complex" subscript (inside brackets) with space.
+
+g) Put empty lines between chunks of code that do different things.
+
+*) Always check the return code of system calls.
+
+h) Put a newline between closing brace and else or elsif.
+
+i) Do not put space between a function name and its opening parenthesis.

+j) Do not put space before a semicolon.
+
+k) Put space after each comma.
+
+l) Break long lines after an operator (but before 'and' and 'or', even when
+spelled as && and ||)).
+
+*) Always check the return code of system calls.
+
+m) Line up corresponding items vertically.
+
+n) Use redundant parentheses only where it increases readability.
+
+o) An opening brace should be put on the same line as its preceding keyword,
+if  possible; otherwise, line them up vertically.
+
+	while ($condition) {
+		# do something
+	}
+
+	while ($this_condition and $that_condition and $some_other_condition
+	       and $this_really_really_really_long_condition)
+	{
+		# do something
+	}
+
+p) Do things the most readable way. For instance:
+
+	open(FOO, $foo) or die "Can't open $foo: $!";
+
+is  better than
+
+	die "Can't open $foo: $!" unless open(FOO, $foo);
+
+because the second way hides the main point of the statement in a modifier.
+
+q) Just because an operator lets you assume default arguments doesn't mean
+that you should always use them. The defaults are there for lazy programmers
+writing one-shot, non-shared programs. If you want your program to be readable,
+consider supplying the argument.
+
+r) Choose mnemonic identifiers. That is, don't name your variables $h, $c
+and $w. Try $hostaddress, $critical and $warning instead ($host, $crit and
+$warn is OK too).
+
+s) Use underscore to split words in long identifiers. That is, use
+$service_port instead of $ServicePort as the former is much more readable.
+
+*) Always check the return code of system calls.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://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,

+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

+
+                     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.>

+    along with this program.  If not, see <http://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

+Frequently Asked Questions
+**************************
+
+Q: Where can I find documentation for <insert name> plugin?
+
+A: All plugins that comply with minimal development guideline for
+   this project include internal documentation.  The documentation
+   can be read executing plugin with the -h or --help option. If 
+   the '-h' option does not work, that is a bug.
+
+
+Q: What version of <insert name> plugin am I running?
+
+A: All plugins that comply with minimal development guideline for
+   this project include detailed version information.  When executed
+   with the '-V' option, a version string will be printed:
+
+   check_radius v1.4.16 (monitoring-plugins 1.4.16)
+
+   All bug reports and help requests should reference this
+   information.
+
+
+Q: What information do I need to include when asking for help or
+   submitting a bug report?
+
+A: At a minimum, the output from 'uname -a' and the version string
+   from '<plugin_name> -V' and, of course, a description of the
+   problem and any solution/patch.
+
+
+Q: I get an error like
+
+   Warning: Return code of 127 for check of service 'PING' on host 'anyhost' was out of bounds.
+
+   when I run Nagios. (Often check_ping runs just fine on the
+   command line).
+
+A: Commonly, system administrators will make security as tight as
+   possible on the monitoring system. Sometimes this includes OS
+   options or hardening scripts that prevent unprivileged users from
+   running the ping command. Nagios runs with no more privileges
+   than 'nobody' -- check to be sure that the nagios user can
+   actually run check ping.  (This can also happen with other binaries
+   executed by nagios, but ping seems to be far and away the biggest
+   offender.)
+
+
+Q: I have a plugin to offer. What can I do?
+
+A: You can make it available on MonitoringExchange (http://monitoringexchange.org)
+   where other people can find it for use.
+
+   You can also get feedback on improving the plugin via the 
+   devel@monitoring-plugins.org mailing list.

+Installation Instructions
+*************************
+
+   Copyright (C) 1994-1996, 1999-2002, 2004-2016 Free Software
+Foundation, Inc.
+
+   Copying and distribution of this file, with or without modification,
+are permitted in any medium without royalty provided the copyright
+notice and this notice are preserved.  This file is offered as-is,
+without warranty of any kind.
+
+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.

+
+	WARNINGS
+	New default installation prefix: /usr/local instead of /usr/local/nagios
+	check_snmp now evaluates negative values properly, which means it might return CRITICAL
+	  in cases where it used to return OK. If this is undesired, the warning/critical
+	  threshold(s) must be fixed by specifying e.g. ~:100 instead of 100
+	check_procs now ignores its parent process to avoid unexpected results when invoked via
+	  certain shells
+	utils.sh no longer defines ECH
+	check_ide_smart -q/--quiet and -n/--nagios (Nagios-compatible output) are now deprecated
+	  but accepted for backward-compatibility
+	check_ide_smart -0/--auto-off, -1/--auto-on and -i/--immediate: options have
+	  been disabled because they were broken
+	State retention: the NAGIOS_PLUGIN_STATE_DIRECTORY environment variable has been
+	  renamed MP_STATE_PATH. The old variable will continue to work in v2.0.x
+	Add the UID of the invoking user to the state retention file path. This helps solving
+	  permission issues when different users run the same plugin
+	check_swap used to allow returning OK on a system without swap when only percent thresholds
+	  were used. This is no longer the case and one must now use -n/--no-swap=<state>
+	The Perl and Shell plugins now use the PATH specified via ./configure's --trusted-path

+=head1 NAME
+
+NPTest - Simplify the testing of Monitoring Plugins
+
+=head1 DESCRIPTION
+
+This modules provides convenience functions to assist in the testing
+of Monitoring Plugins, making the testing code easier to read and write;
+hopefully encouraging the development of a more complete test suite for
+the Monitoring Plugins. It is based on the patterns of testing seen in the
+1.4.0 release, and continues to use the L<Test> module as the basis of
+testing.
+
+=head1 FUNCTIONS
+
+This module defines four public functions, C<getTestParameter(...)>,
+C<checkCmd(...)>, C<skipMissingCmd(...)> and C<skipMsg(...)>.  These are exported by
+default via the C<use NPTest;> statement.
+
+=over
+
+=item getTestParameter( "ENV_VARIABLE", $brief_description, $default )
+
+$default is optional.
+
+This function allows the test harness
+developer to interactively request test parameter information from the
+user. The user can accept the developer's default value or reply "none"
+which will then be returned as "" for the test to skip if appropriate.
+
+If a parameter needs to be entered and the test is run without a tty
+attached (such as a cronjob), the parameter will be assigned as if it
+was "none". Tests can check for the parameter and skip if not set.
+
+Responses are stored in an external, file-based cache so subsequent test
+runs will use these values. The user is able to change the values by
+amending the values in the file /var/tmp/NPTest.cache, or by setting
+the appropriate environment variable before running the test.
+
+To facilitate quick testing setup, it is possible to accept all the
+developer provided defaults by setting the environment variable
+"NPTEST_ACCEPTDEFAULT" to "1" (or any other perl truth value). Note
+that, such defaults are not stored in the cache, as there is currently
+no mechanism to edit existing cache entries, save the use of text
+editor or removing the cache file completely.
+
+=item C<testCmd($command)>
+
+Call with NPTest->testCmd("./check_disk ...."). This returns a NPTest object
+which you can then run $object->return_code or $object->output against.
+
+Testing of results would be done in your test script, not in this module.
+
+=item C<checkCmd(...)>
+
+This function is obsolete. Use C<testCmd()> instead.
+
+This function attempts to encompass the majority of test styles used
+in testing Monitoring Plugins. As each plug-in is a separate command, the
+typical tests we wish to perform are against the exit status of the
+command and the output (if any) it generated. Simplifying these tests
+into a single function call, makes the test harness easier to read and
+maintain and allows additional functionality (such as debugging) to be
+provided without additional effort on the part of the test harness
+developer.
+
+It is possible to enable debugging via the environment variable
+C<NPTEST_DEBUG>. If this environment variable exists and its value in PERL's
+boolean context evaluates to true, debugging is enabled.
+
+The function prototype can be expressed as follows:
+
+  Parameter 1 : command => DEFINED SCALAR(string)
+  Parameter 2 : desiredExitStatus => ONE OF
+                  SCALAR(integer)
+                  ARRAYREF(integer)
+                  HASHREF(integer,string)
+                  UNDEFINED
+  Parameter 3 : desiredOutput => SCALAR(string) OR UNDEFINED
+  Parameter 4 : exceptions => HASH(integer,string) OR UNDEFINED
+  Returns     : SCALAR(integer) as defined by Test::ok(...)
+
+The function treats the first parameter C<$command> as a command line
+to execute as part of the test, it is executed only once and its exit
+status (C<$?E<gt>E<gt>8>) and output are captured.
+
+At this point if debugging is enabled the command, its exit status and
+output are displayed to the tester.
+
+C<checkCmd(...)> allows the testing of either the exit status or the
+generated output or both, not testing either will result in neither
+the C<Test::ok(...)> or C<Test::skip(...)> functions being called,
+something you probably don't want. Note that each defined test
+(C<$desiredExitStatus> and C<$desiredOutput>) results in a invocation
+of either C<Test::ok(...)> or C<Test::skip(...)>, so remember this
+when counting the number of tests to place in the C<Test::plan(...)>
+call.
+
+Many Monitoring Plugins test network services, some of which may not be
+present on all systems. To cater for this, C<checkCmd(...)> allows the
+tester to define exceptions based on the command's exit status. These
+exceptions are provided to skip tests if the test case developer
+believes the service is not being provided. For example, if a site
+does not have a POP3 server, the test harness could map the
+appropriate exit status to a useful message the person running the
+tests, telling the reason the test is being skipped.
+
+Example:
+
+my %exceptions = ( 2 =E<gt> "No POP Server present?" );
+
+$t += checkCmd( "./check_pop I<some args>", 0, undef, %exceptions );
+
+Thus, in the above example, an exit status of 2 does not result in a
+failed test case (as the exit status is not the desired value of 0),
+but a skipped test case with the message "No POP Server present?"
+given as the reason.
+
+Sometimes the exit status of a command should be tested against a set
+of possible values, rather than a single value, this could especially
+be the case in failure testing. C<checkCmd(...)> support two methods
+of testing against a set of desired exit status values.
+
+=over
+
+=item *
+
+Firstly, if C<$desiredExitStatus> is a reference to an array of exit
+statuses, if the actual exit status of the command is present in the
+array, it is used in the call to C<Test::ok(...)> when testing the
+exit status.
+
+=item *
+
+Alternatively, if C<$desiredExitStatus> is a reference to a hash of
+exit  statuses(mapped to the strings "continue" or "skip"), similar
+processing to the above occurs with the side affect of determining if
+any generated output testing should proceed. Note: only the string
+"skip" will result in generated output testing being skipped.
+
+=back
+
+=item C<skipMissingCmd(...)>
+
+If a command is missing and the test harness must C<Test::skip()> some
+or all of the tests in a given test harness this function provides a
+simple iterator to issue an appropriate message the requested number
+of times.
+
+=back
+
+=item C<skipMsg(...)>
+
+If for any reason the test harness must C<Test::skip()> some
+or all of the tests in a given test harness this function provides a
+simple iterator to issue an appropriate message the requested number
+of times.

+Monitoring Plugins
+==================
+
+* For instructions on installing these plugins for use with your monitoring
+  system, see below.  In addition, generic instructions for the GNU
+  toolchain can be found in the `INSTALL` file.
+
+* For major changes between releases, read the `NEWS` file.
+
+* For information on detailed changes that have been made or plugins
+  that have been added, read the `ChangeLog` file.
+
+* Some plugins require that you have additional programs or
+  libraries installed on your system before they can be used.  Plugins that
+  are dependent on other programs/libraries that are missing are usually not
+  compiled.  Read the `REQUIREMENTS` file for more information.
+
+* Individual plugins are self-documenting.  All plugins that comply with
+  the basic guidelines for development will provide detailed help when
+  invoked with the `-h` or `--help` options.
+
+You can check the latest plugins at:
+
+* <https://www.monitoring-plugins.org/>
+
+Send an email to <help@monitoring-plugins.org> for assistance.  Please
+include the OS type and version that you are using.  Also, run the plugin
+with the `-vvv` option and provide the resulting version information.  Of
+course, there may be additional diagnostic information required as well.
+Use good judgment.
+
+Send an email to <devel@monitoring-plugins.org> for developer discussions.
+
+For patch submissions and bug reports, please use the appropriate resources
+at:
+
+* <https://github.com/monitoring-plugins>
+
+
+Installation Instructions
+-------------------------
+
+1.  If you are using the Git tree, you will need m4, gettext, automake, and
+    autoconf.  To start out, run:
+
+    	./tools/setup
+
+    For more detail, see the developer guidelines at
+    <https://www.monitoring-plugins.org/doc/guidelines.html>.
+
+2.  Run the configure script to initialize variables and create a Makefile,
+    etc.
+
+    	./configure --prefix=BASEDIRECTORY --with-cgiurl=SOMEURL
+
+    Replace `BASEDIRECTORY` with the path of the directory under which your
+    monitoring system is installed (default is `/usr/local`), and replace
+    `SOMEURL` with the path used to access the monitoring system CGIs with a
+    web browser (default is `/nagios/cgi-bin`).
+
+3.  Compile the plugins with the following command:
+
+    	make
+
+4.  Install the compiled plugins and plugin scripts with the following
+    command:
+
+    	make install
+
+    The installation procedure will attempt to place the plugins in a
+    `libexec/` subdirectory in the base directory you specified with the
+    `--prefix` argument to the configure script.
+
+5.  There are some plugins that require setuid.  If you run make install as
+    a non-root user, they will not be installed.  To install, switch to root
+    and run:
+
+    	make install-root
+
+That's it!  If you have any problems or questions, feel free to send an
+email to <help@monitoring-plugins.org>.

+Monitoring Plugins Requirements
+--------------------------
+
+Some plugins require that you have additional programs and/or
+libraries installed on your system before they can be used.  Plugins
+that are dependent on other programs/libraries that are missing are
+usually not compiled.  Requirements for various plugins are listed
+below...
+
+check_ldaps, check_http --ssl, check_tcp --ssl, check_smtp --starttls
+	- Requires openssl or gnutls libraries for SSL connections
+	  http://www.openssl.org, http://www.gnu.org/software/gnutls
+
+check_curl:
+	- Requires libcurl 7.15.2 or later
+	  http://www.haxx.se
+	- --ssl/-S and -C requires OpenSSL for certificate checks, otherwise
+	  libcurl must be quite new to support CURLINFO_CERTINFO with
+	  GnuTLS and NSS libraries:
+	  - 7.42.0 or newer for GnuTLS
+	  - 7.34.0 or newer for NSS
+	  GnuTLS is known to create problems on some distributions with
+	  self-signed certificate chains
+	  http://www.openssl.org, http://www.gnu.org/software/gnutls,
+	  http://www.mozilla.org/projects/security/pki/nss/,
+	  other SSL implementations are currently not supported
+	- uriparser 0.7.5 or later
+	  https://uriparser.github.io/
+      
+check_fping:
+	- Requires the fping utility distributed with SATAN.  Either
+	  download and install SATAN or grab the fping program from
+	  http://www.fping.com/
+		RPM: http://rpmfind.net/linux/rpm2html/search.php?query=fping
+	  Note that the fping command must be setuid root to function.
+
+check_game:
+	- Requires the qstat utility available from
+	  http://sourceforge.net/projects/qstat/
+	  Last tested on qstat 2.3d BETA
+

+SUPPORT
+
+Using the mailing lists and issue tracker at GitHub are the
+best ways to obtain direct support for the Monitoring Plugins. There may
+also be commercial support options available to you -- check
+http://www.nagios.org/ to track the current status of commercial
+support offerings.
+
+There are two mailing lists associated with Monitoring Plugins development:
+'help' (mailto:help@monitoring-plugins.org), and 'devel'
+(mailto:help@monitoring-plugins.org). Unless you are fairly
+certain you have found a bug or that you are requesting a new feature,
+please direct support requests to 'help'.
+
+Because these lists are handled entirely by volunteers, and because
+these same volunteers are often plugin developers who can also use
+their time to fix bug and provide feature requests, it is generally in
+you interest to do a modest amount of legwork before posting to either
+of these lists.
+
+Plugins that are in the contrib directories are provided as-is. We will
+try to help, but sometimes the plugins have dependencies that the monitoring-plugin
+developers do not have access to. You may be able to try the authors
+directly.
+
+In brief, always provide the version of the software that you are
+using, and when requesting features or reporting bugs, first check to
+see that the issue has not already been addressed in the current Git
+code.
+
+GETTING HELP
+
+Requests to 'help' require posting the version number of the
+plugin. The best place to include the version information is in the
+subject. A good post would have a subject like:
+
+  Can I use SSL with check_imap (monitoring-plugins 1.3.0-beta2) 1.12
+
+If you do not include the version of the plugin, you risk having your
+post silently ignored.
+
+Be advised that the core plugins (and in fact many of the contributed
+plugins) will provide a description of their use when invoked with the
+'--help' option. Please read the help carefully and in it's entirety
+before asking for support.
+
+REPORTING BUGS AND SUBMITTING PATCHES
+
+Bug reports, investigations of possible bugs, feature requests, and
+patch submissions should be submitted to the development list at
+mailto:devel@monitoring-plugins.org. Please raise an issue first
+in GitHub, otherwise your email is likely to be missed over time.
+
+You should identify the version, preferably in the subject line.
+However, to best use developer resources, it is suggested that you
+reference your report to one of the following sources:
+
+  1) The most recent release, including beta's
+
+  2) The current snapshots (there's a link provided on
+     https://www.monitoring-plugins.org/download.html)
+
+  3) The current Git code from GitHub
+
+(This does not mean you should run any of these sources in a
+production environment - the latter two you clearly should
+not. However, if you find a bug, you should determine whether it is
+still present in one of these sources, preferably either (2) or (3)
+which are most recent.)
+
+From experience, I know that most bugs can be fixed with only a few
+more moments work than it takes to determine if the bug is still
+present in the Git tree. If you can save a developer the expense of
+that time, you ensure that bugs are fixed more rapidly, and thus you
+ensure your problem resolution is reflected in a stable release more
+quickly.

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+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        if { eval "gt_val=\$$gt_func_gnugettext_libc"; test "$gt_val" != "yes"; }; then
+  dnl tests. But if configure.in invokes AM_ICONV after AM_GNU_GETTEXT
+  dnl the configure script would need to contain the same shell code
+  dnl again, outside any 'if'. There are two solutions:

+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.

+# 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.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+##   -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

+## 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.

+   Suppress extern inline with HP-UX cc, as it appears to be broken; see
+   <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
+
+   Suppress extern inline with Sun C in standards-conformance mode, as it
+   mishandles inline functions that call each other.  E.g., for 'inline void f
+   (void) { } inline void g (void) { f (); }', c99 incorrectly complains
+   'reference to static identifier "f" in extern inline function'.
+   This bug was observed with Oracle Developer Studio 12.6
+   (Sun C 5.15 SunOS_sparc 2017/05/30).
+
+   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
+   on configurations that mistakenly use 'static inline' to implement
+   functions or macros in standard C headers like <ctype.h>.  For example,
+   if isdigit is mistakenly implemented via a static inline function,
+   a program containing an extern inline function that calls isdigit
+   may not work since the C standard prohibits extern inline functions
+   from calling static functions (ISO C 99 section 6.7.4.(3).
+   This bug is known to occur on:
+
+     OS X 10.8 and earlier; see:
+     https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
+
+     DragonFly; see
+     http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
+
+     FreeBSD; see:
+     https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
+
+   OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
+   for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
+   Assume DragonFly and FreeBSD will be similar.
+
+   GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+   inline semantics, unless -fgnu89-inline is used.  It defines a macro
+   __GNUC_STDC_INLINE__ to indicate this situation or a macro
+   __GNUC_GNU_INLINE__ to indicate the opposite situation.
+   GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
+   semantics but warns, unless -fgnu89-inline is used:
+     warning: C99 inline functions are not supported; using GNU89
+     warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
+   It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files

+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.

+                          Valid ARGs are:

+                          Default is 'no'.
+                          Note also --with-linux-crypto, which will enable the
+                          use of Linux kernel crypto routines (if available),
+                          which has precedence for files.
+  --without-included-regex
+                          don't compile regex; this is the default on systems
+                          with recent-enough versions of the GNU C Library
+                          (use with caution on other systems).
+
+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>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+Your 'rm' program seems unable to run without file operands specified

+the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>

+Please tell bug-automake@gnu.org about your system, including the value
+of your $PATH and any error possibly output before this message.  This

+      Must be a preprocessor constant.  If DYNARRAY_INITIAL_SIZE is 0,
+      there is no statically allocated array at, and all non-empty
+      arrays are heap-allocated.

+       - With mingw, it also requires
+         "#define GetComputerNameEx GetComputerNameExA".
+       - With older versions of mingw, none of the declarations are present at

+/* Compile-time symbols that this file uses:
+
+   HAVE_PSTAT_GETDYNAMIC        Define this if your system has the
+                                pstat_getdynamic function.  I think it
+                                is unique to HPUX9.  The best way to get the
+                                definition is through the AC_FUNC_GETLOADAVG
+                                macro that comes with autoconf 2.13 or newer.
+                                If that isn't an option, then just put
+                                AC_CHECK_FUNCS(pstat_getdynamic) in your
+                                configure.ac file.
+   HAVE_LIBPERFSTAT Define this if your system has the
+                                perfstat_cpu_total function in libperfstat (AIX).
+   FIXUP_KERNEL_SYMBOL_ADDR()   Adjust address in returned struct nlist.
+   KERNEL_FILE                  Name of the kernel file to nlist.
+   LDAV_CVT()                   Scale the load average from the kernel.
+                                Returns a double.
+   LDAV_SYMBOL                  Name of kernel symbol giving load average.
+   LOAD_AVE_TYPE                Type of the load average array in the kernel.
+                                Must be defined unless one of
+                                apollo, DGUX, NeXT, or UMAX is defined;
+                                or we have libkstat;
+                                otherwise, no load average is available.
+   HAVE_NLIST_H                 nlist.h is available.  NLIST_STRUCT defaults
+                                to this.
+   NLIST_STRUCT                 Include nlist.h, not a.out.h.
+   N_NAME_POINTER               The nlist n_name element is a pointer,
+                                not an array.
+   HAVE_STRUCT_NLIST_N_UN_N_NAME 'n_un.n_name' is member of 'struct nlist'.
+   LINUX_LDAV_FILE              [__linux__, __ANDROID__, __CYGWIN__]: File
+                                containing load averages.
+
+   Specific system predefines this file uses, aside from setting
+   default values if not emacs:
+
+   apollo
+   BSD                          Real BSD, not just BSD-like.
+   DGUX
+   eunice                       UNIX emulator under VMS.

+   __NetBSD__                   NetBSD: assumes /kern file system mounted.
+
+   In addition, to avoid nesting many #ifdefs, we internally set
+   LDAV_DONE to indicate that the load average has been computed.
+

+/* 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.
+
+   The elements of ARGV aren't really const, because we permute them.
+   But we pretend they're const in the prototype to be compatible
+   with other systems.
+
+   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.  */

+/* This module allows programs which are installed with setuid or setgid bit
+   (and which therefore initially run with an effective user id or group id
+   different from the one of the current user) to drop their uid or gid
+   privilege, either permanently or temporarily.
+
+   It is absolutely necessary to minimize the amount of code that is running
+   with escalated privileges (e.g. with effective uid = root). The reason is
+   that any bug or exploit in a part of a program that is running with
+   escalated privileges is a security vulnerability that - upon discovery -
+   puts the users in danger and requires immediate fixing. Then consider that
+   there's a bug every 10 or 20 lines of code on average...
+
+   For programs that temporarily drop privileges but have the ability to
+   restore them later, there are additionally the dangers that
+     - Any bug in the non-privileged part of the program may be used to
+       create invalid data structures that will trigger security
+       vulnerabilities in the privileged part of the program.
+     - Code execution exploits in the non-privileged part of the program may
+       be used to invoke the function that restores high privileges and then
+       execute additional arbitrary code.
+
+   1) The usual, and reasonably safe, way to minimize the amount of code
+      running with privileges is to create a separate executable, with setuid
+      or setgid bit, that contains only code for the tasks that require
+      privileges (and,of course, strict checking of the arguments, so that the
+      program cannot be abused). The main program is installed without setuid
+      or setgid bit.
+
+   2) A less safe way is to do some privileged tasks at the beginning of the
+      program's run, and drop privileges permanently as soon as possible.
+
+      Note: There may still be security issues if the privileged task puts
+      sensitive data into the process memory or opens communication channels
+      to restricted facilities.
+
+   3) The most unsafe way is to drop privileges temporarily for most of the
+      main program but to re-enable them for the duration of privileged tasks.
+
+      As explained above, this approach has uncontrollable dangers for
+      security.
+
+      This approach is normally not usable in multithreaded programs, because
+      you cannot know what kind of system calls the other threads could be
+      doing during the time the privileges are enabled.
+
+   With approach 1, you don't need gnulib modules.
+   With approach 2, you need the gnulib module 'idpriv-drop'.
+   With approach 3, you need the gnulib module 'idpriv-droptemp'. But really,
+   you should better stay away from this approach.

+/* The type 'idx_t' holds an (array) index or an (object) size.
+   Its implementation promotes to a signed integer type,
+   which can hold the values
+     0..2^63-1 (on 64-bit platforms) or
+     0..2^31-1 (on 32-bit platforms).
+
+   Why a signed integer type?
+
+     * Security: Signed types can be checked for overflow via
+       '-fsanitize=undefined', but unsigned types cannot.
+
+     * Comparisons without surprises: ISO C99 § 6.3.1.8 specifies a few
+       surprising results for comparisons, such as
+
+           (int) -3 < (unsigned long) 7  =>  false
+           (int) -3 < (unsigned int) 7   =>  false
+       and on 32-bit machines:
+           (long) -3 < (unsigned int) 7  =>  false
+
+       This is surprising because the natural comparison order is by
+       value in the realm of infinite-precision signed integers (ℤ).
+
+       The best way to get rid of such surprises is to use signed types
+       for numerical integer values, and use unsigned types only for
+       bit masks and enums.
+
+   Why not use 'size_t' directly?
+
+     * Because 'size_t' is an unsigned type, and a signed type is better.
+       See above.
+
+   Why not use 'ssize_t'?
+
+     * 'ptrdiff_t' is more portable; it is standardized by ISO C
+       whereas 'ssize_t' is standardized only by POSIX.
+
+     * 'ssize_t' is not required to be as wide as 'size_t', and some
+       now-obsolete POSIX platforms had 'size_t' wider than 'ssize_t'.
+
+     * Conversely, some now-obsolete platforms had 'ptrdiff_t' wider
+       than 'size_t', which can be a win and conforms to POSIX.
+
+   Won't this cause a problem with objects larger than PTRDIFF_MAX?
+
+     * Typical modern or large platforms do not allocate such objects,
+       so this is not much of a problem in practice; for example, you
+       can safely write 'idx_t len = strlen (s);'.  To port to older
+       small platforms where allocations larger than PTRDIFF_MAX could
+       in theory be a problem, you can use Gnulib's ialloc module, or
+       functions like ximalloc in Gnulib's xalloc module.
+
+   Why not use 'ptrdiff_t' directly?
+
+     * Maintainability: When reading and modifying code, it helps to know that
+       a certain variable cannot have negative values.  For example, when you
+       have a loop
+
+         int n = ...;
+         for (int i = 0; i < n; i++) ...
+
+       or
+
+         ptrdiff_t n = ...;
+         for (ptrdiff_t i = 0; i < n; i++) ...
+
+       you have to ask yourself "what if n < 0?".  Whereas in
+
+         idx_t n = ...;
+         for (idx_t i = 0; i < n; i++) ...
+
+       you know that this case cannot happen.
+
+       Similarly, when a programmer writes
+
+         idx_t = ptr2 - ptr1;
+
+       there is an implied assertion that ptr1 and ptr2 point into the same
+       object and that ptr1 <= ptr2.
+
+     * Being future-proof: In the future, range types (integers which are
+       constrained to a certain range of values) may be added to C compilers
+       or to the C standard.  Several programming languages (Ada, Haskell,
+       Common Lisp, Pascal) already have range types.  Such range types may
+       help producing good code and good warnings.  The type 'idx_t' could
+       then be typedef'ed to a range type that is signed after promotion.  */
+
+/* In the future, idx_t could be typedef'ed to a signed range type.
+   The clang "extended integer types", supported in Clang 11 or newer
+   <https://clang.llvm.org/docs/LanguageExtensions.html#extended-integer-types>,
+   are a special case of range types.  However, these types don't support binary
+   operators with plain integer types (e.g. expressions such as x > 1).
+   Therefore, they don't behave like signed types (and not like unsigned types
+   either).  So, we cannot use them here.  */
+
+/* Use the signed type 'ptrdiff_t'.  */

+   The INT_<op>_RANGE_OVERFLOW macros return 1 if the corresponding C

+   Although their implementations are simple and straightforward,

+

+   so the arguments should not have side effects.  The arithmetic
+   arguments (including the MIN and MAX arguments) must be of the same
+   integer type after the usual arithmetic conversions, and the type
+   must have minimum value MIN and maximum MAX.  Unsigned types should

+/* Check for integer overflow, and report low order bits of answer.
+
+   The INT_<op>_OVERFLOW macros return 1 if the corresponding C operators
+   might not yield numerically correct answers due to arithmetic overflow.
+   The INT_<op>_WRAPV macros compute the low-order bits of the sum,
+   difference, and product of two C integers, and return 1 if these
+   low-order bits are not numerically correct.
+   These macros work correctly on all known practical hosts, and do not rely
+   on undefined behavior due to signed arithmetic overflow.
+
+   Example usage, assuming A and B are long int:
+
+     if (INT_MULTIPLY_OVERFLOW (a, b))
+       printf ("result would overflow\n");
+     else
+       printf ("result is %ld (no overflow)\n", a * b);
+
+   Example usage with WRAPV flavor:
+
+     long int result;
+     bool overflow = INT_MULTIPLY_WRAPV (a, b, &result);
+     printf ("result is %ld (%s)\n", result,
+             overflow ? "after overflow" : "no overflow");
+
+   Restrictions on these macros:
+
+   These macros do not check for all possible numerical problems or
+   undefined or unspecified behavior: they do not check for division
+   by zero, for bad shift counts, or for shifting negative numbers.
+
+   These macros may evaluate their arguments zero or multiple times, so the
+   arguments should not have side effects.
+
+   The WRAPV macros are not constant expressions.  They support only
+   +, binary -, and *.
+
+   Because the WRAPV macros convert the result, they report overflow
+   in different circumstances than the OVERFLOW macros do.  For
+   example, in the typical case with 16-bit 'short' and 32-bit 'int',
+   if A, B and *R are all of type 'short' then INT_ADD_OVERFLOW (A, B)
+   returns false because the addition cannot overflow after A and B
+   are converted to 'int', whereas INT_ADD_WRAPV (A, B, R) returns
+   true or false depending on whether the sum fits into 'short'.
+
+   These macros are tuned for their last input argument being a constant.
+
+   A, B, and *R should be integers; they need not be the same type,
+   and they need not be all signed or all unsigned.
+   However, none of the integer types should be bit-precise,
+   and *R's type should not be char, bool, or an enumeration type.
+
+   Return 1 if the integer expressions A * B, A - B, -A, A * B, A / B,
+   A % B, and A << B would overflow, respectively.  */

+    /* Darwin 7.5 has nl_langinfo(CODESET), but sometimes its value is
+       useless:
+       - It returns the empty string when LANG is set to a locale of the
+         form ll_CC, although ll_CC/LC_CTYPE is a symlink to an UTF-8
+         LC_CTYPE file.
+       - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
+         the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
+       - The documentation says:
+           "... all code that calls BSD system routines should ensure
+            that the const *char parameters of these routines are in UTF-8
+            encoding. All BSD system functions expect their string
+            parameters to be in UTF-8 encoding and nothing else."
+         It also says
+           "An additional caveat is that string parameters for files,
+            paths, and other file-system entities must be in canonical
+            UTF-8. In a canonical UTF-8 Unicode string, all decomposable
+            characters are decomposed ..."
+         but this is not true: You can pass non-decomposed UTF-8 strings
+         to file system functions, and it is the OS which will convert
+         them to decomposed UTF-8 before accessing the file system.
+       - The Apple Terminal application displays UTF-8 by default.
+       - However, other applications are free to use different encodings:
+         - xterm uses ISO-8859-1 by default.
+         - TextEdit uses MacRoman by default.
+       We prefer UTF-8 over decomposed UTF-8-MAC because one should
+       minimize the use of decomposed Unicode. Unfortunately, through the
+       Darwin file system, decomposed UTF-8 strings are leaked into user
+       space nevertheless.
+       Then there are also the locales with encodings other than US-ASCII
+       and UTF-8. These locales can be occasionally useful to users (e.g.
+       when grepping through ISO-8859-1 encoded text files), when all their
+       file names are in US-ASCII.

+

+   mishandles inline functions that call each other.  E.g., for 'inline void f
+   (void) { } inline void g (void) { f (); }', c99 incorrectly complains
+   'reference to static identifier "f" in extern inline function'.
+   This bug was observed with Oracle Developer Studio 12.6
+   (Sun C 5.15 SunOS_sparc 2017/05/30).
+
+   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
+   on configurations that mistakenly use 'static inline' to implement
+   functions or macros in standard C headers like <ctype.h>.  For example,
+   if isdigit is mistakenly implemented via a static inline function,
+   a program containing an extern inline function that calls isdigit
+   may not work since the C standard prohibits extern inline functions
+   from calling static functions (ISO C 99 section 6.7.4.(3).

+
+dnl Sets INCLUDE_NEXT, INCLUDE_NEXT_AS_FIRST_DIRECTIVE, PRAGMA_SYSTEM_HEADER,
+dnl and PRAGMA_COLUMNS.
+dnl
+dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
+dnl 'include' otherwise.
+dnl
+dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
+dnl supports it in the special case that it is the first include directive in
+dnl the given file, or to 'include' otherwise.
+dnl
+dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
+dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
+dnl '#pragma GCC system_header' has the same effect as if the file was found
+dnl through the include search path specified with '-isystem' options (as
+dnl opposed to the search path specified with '-I' options). Namely, gcc
+dnl does not warn about some things, and on some systems (Solaris and Interix)
+dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
+dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
+dnl of plain '__STDC__'.
+dnl
+dnl PRAGMA_COLUMNS can be used in files that override system header files, so
+dnl as to avoid compilation errors on HP NonStop systems when the gnulib file
+dnl is included by a system header file that does a "#pragma COLUMNS 80" (which
+dnl has the effect of truncating the lines of that file and all files that it
+dnl includes to 80 columns) and the gnulib file has lines longer than 80
+dnl columns.

+# using a macro with the same name in our local m4/libtool.m4 it'll

+dnl Test whether in a situation where
+dnl   - an rwlock is taken by a reader and has a writer waiting,
+dnl   - an additional reader requests the lock,
+dnl   - the waiting writer and the requesting reader threads have the same
+dnl     priority,
+dnl the requesting reader thread gets blocked, so that at some point the
+dnl waiting writer can acquire the lock.
+dnl Without such a guarantee, when there a N readers and each of the readers
+dnl spends more than 1/Nth of the time with the lock held, there is a high
+dnl probability that the waiting writer will not get the lock in a given finite
+dnl time, a phenomenon called "writer starvation".
+dnl Without such a guarantee, applications have a hard time avoiding writer
+dnl starvation.
+dnl

+dnl       cnd

+dnl ------------
+dnl Tests for a multithreading library to be used.
+dnl If the configure.ac contains a definition of the gl_THREADLIB_DEFAULT_NO
+dnl (it must be placed before the invocation of gl_THREADLIB_EARLY!), then the
+dnl default is 'no', otherwise it is system dependent. In both cases, the user
+dnl can change the choice through the options --enable-threads=choice or
+dnl --disable-threads.
+dnl Defines at most one of the macros USE_ISOC_THREADS, USE_POSIX_THREADS,
+dnl USE_ISOC_AND_POSIX_THREADS, USE_WINDOWS_THREADS.
+dnl The choice --enable-threads=isoc+posix is available only on platforms that
+dnl have both the ISO C and the POSIX threads APIs. It has the effect of using
+dnl the ISO C API for most things and the POSIX API only for creating and
+dnl controlling threads (because there is no equivalent to pthread_atfork in
+dnl the ISO C API).
+dnl Sets the variables LIBTHREAD and LTLIBTHREAD to the linker options for use
+dnl in a Makefile (LIBTHREAD for use without libtool, LTLIBTHREAD for use with
+dnl libtool).
+dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for
+dnl programs that really need multithread functionality. The difference
+dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak
+dnl symbols, typically LIBTHREAD is empty whereas LIBMULTITHREAD is not.
+dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for
+dnl multithread-safe programs.
+dnl Since support for GNU pth was removed, $LTLIBTHREAD and $LIBTHREAD have the
+dnl same value, and similarly $LTLIBMULTITHREAD and $LIBMULTITHREAD have the
+dnl same value. Only system libraries are needed.

+/* Pre-processor macros which act as parameters:
+
+   DYNARRAY_STRUCT
+      The struct tag of dynamic array to be defined.
+   DYNARRAY_ELEMENT
+      The type name of the element type.  Elements are copied
+      as if by memcpy, and can change address as the dynamic
+      array grows.
+   DYNARRAY_PREFIX
+      The prefix of the functions which are defined.
+
+   The following parameters are optional:
+
+   DYNARRAY_ELEMENT_FREE
+      DYNARRAY_ELEMENT_FREE (E) is evaluated to deallocate the
+      contents of elements. E is of type  DYNARRAY_ELEMENT *.
+   DYNARRAY_ELEMENT_INIT
+      DYNARRAY_ELEMENT_INIT (E) is evaluated to initialize a new
+      element.  E is of type  DYNARRAY_ELEMENT *.
+      If DYNARRAY_ELEMENT_FREE but not DYNARRAY_ELEMENT_INIT is
+      defined, new elements are automatically zero-initialized.
+      Otherwise, new elements have undefined contents.
+   DYNARRAY_INITIAL_SIZE
+      The size of the statically allocated array (default:
+      at least 2, more elements if they fit into 128 bytes).
+      Must be a preprocessor constant.  If DYNARRAY_INITIAL_SIZE is 0,
+      there is no statically allocated array at, and all non-empty
+      arrays are heap-allocated.
+   DYNARRAY_FINAL_TYPE
+      The name of the type which holds the final array.  If not
+      defined, is PREFIX##finalize not provided.  DYNARRAY_FINAL_TYPE
+      must be a struct type, with members of type DYNARRAY_ELEMENT and
+      size_t at the start (in this order).
+
+   These macros are undefined after this header file has been
+   included.
+
+   The following types are provided (their members are private to the
+   dynarray implementation):
+
+     struct DYNARRAY_STRUCT
+
+   The following functions are provided:
+
+     void DYNARRAY_PREFIX##init (struct DYNARRAY_STRUCT *);
+     void DYNARRAY_PREFIX##free (struct DYNARRAY_STRUCT *);
+     bool DYNARRAY_PREFIX##has_failed (const struct DYNARRAY_STRUCT *);

+     size_t DYNARRAY_PREFIX##size (const struct DYNARRAY_STRUCT *);
+     DYNARRAY_ELEMENT *DYNARRAY_PREFIX##begin (const struct DYNARRAY_STRUCT *);
+     DYNARRAY_ELEMENT *DYNARRAY_PREFIX##end (const struct DYNARRAY_STRUCT *);
+     DYNARRAY_ELEMENT *DYNARRAY_PREFIX##at (struct DYNARRAY_STRUCT *, size_t);
+     void DYNARRAY_PREFIX##add (struct DYNARRAY_STRUCT *, DYNARRAY_ELEMENT);
+     DYNARRAY_ELEMENT *DYNARRAY_PREFIX##emplace (struct DYNARRAY_STRUCT *);
+     bool DYNARRAY_PREFIX##resize (struct DYNARRAY_STRUCT *, size_t);
+     void DYNARRAY_PREFIX##remove_last (struct DYNARRAY_STRUCT *);
+     void DYNARRAY_PREFIX##clear (struct DYNARRAY_STRUCT *);
+
+   The following functions are provided are provided if the

+
+/* To use the dynarray facility, you need to include
+   <malloc/dynarray-skeleton.c> and define the parameter macros
+   documented in that file.
+
+   A minimal example which provides a growing list of integers can be
+   defined like this:
+
+     struct int_array
+     {
+       // Pointer to result array followed by its length,
+       // as required by DYNARRAY_FINAL_TYPE.
+       int *array;
+       size_t length;
+     };
+
+     #define DYNARRAY_STRUCT dynarray_int
+     #define DYNARRAY_ELEMENT int
+     #define DYNARRAY_PREFIX dynarray_int_
+     #define DYNARRAY_FINAL_TYPE struct int_array
+     #include <malloc/dynarray-skeleton.c>
+
+   To create a three-element array with elements 1, 2, 3, use this
+   code:
+
+     struct dynarray_int dyn;
+     dynarray_int_init (&dyn);
+     for (int i = 1; i <= 3; ++i)
+       {
+         int *place = dynarray_int_emplace (&dyn);
+         assert (place != NULL);
+         *place = i;
+       }
+     struct int_array result;
+     bool ok = dynarray_int_finalize (&dyn, &result);
+     assert (ok);
+     assert (result.length == 3);
+     assert (result.array[0] == 1);
+     assert (result.array[1] == 2);
+     assert (result.array[2] == 3);
+     free (result.array);
+
+   If the elements contain resources which must be freed, define
+   DYNARRAY_ELEMENT_FREE appropriately, like this:
+
+     struct str_array
+     {
+       char **array;
+       size_t length;
+     };
+
+     #define DYNARRAY_STRUCT dynarray_str
+     #define DYNARRAY_ELEMENT char *
+     #define DYNARRAY_ELEMENT_FREE(ptr) free (*ptr)
+     #define DYNARRAY_PREFIX dynarray_str_
+     #define DYNARRAY_FINAL_TYPE struct str_array
+     #include <malloc/dynarray-skeleton.c>
+
+   Compared to scratch buffers, dynamic arrays have the following
+   features:
+
+   - They have an element type, and are not just an untyped buffer of
+     bytes.
+
+   - When growing, previously stored elements are preserved.  (It is
+     expected that scratch_buffer_grow_preserve and
+     scratch_buffer_set_array_size eventually go away because all
+     current users are moved to dynamic arrays.)
+
+   - Scratch buffers have a more aggressive growth policy because
+     growing them typically means a retry of an operation (across an
+     NSS service module boundary), which is expensive.
+
+   - For the same reason, scratch buffers have a much larger initial
+     stack allocation.  */

+     with repeated_c.  This reduces the task to testing whether *any of the
+     four* bytes in longword1 is zero.
+
+     We compute tmp =
+       ((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
+     That is, we perform the following operations:
+       1. Subtract repeated_one.
+       2. & ~longword1.
+       3. & a mask consisting of 0x80 in every byte.
+     Consider what happens in each byte:
+       - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+         and step 3 transforms it into 0x80.  A carry can also be propagated
+         to more significant bytes.
+       - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+         position k (0 <= k <= 7); so the lowest k bits are 0.  After step 1,
+         the byte ends in a single bit of value 0 and k bits of value 1.
+         After step 2, the result is just k bits of value 1: 2^k - 1.  After
+         step 3, the result is 0.  And no carry is produced.
+     So, if longword1 has only non-zero bytes, tmp is zero.
+     Whereas if longword1 has a zero byte, call j the position of the least
+     significant zero byte.  Then the result has a zero at positions 0, ...,
+     j-1 and a 0x80 at position j.  We cannot predict the result at the more
+     significant bytes (positions j+1..3), but it does not matter since we
+     already have a non-zero bit at position 8*j+7.
+
+     So, the test whether any byte in longword1 is zero is equivalent to
+     testing whether tmp is nonzero.  */

+
+   The former two functions operate on STRING with length LENGTH,
+   while the later two operate on concatenation of STRING1 and STRING2
+   with lengths LENGTH1 and LENGTH2, respectively.
+
+   re_match() matches the compiled pattern in BUFP against the string,
+   starting at index START.
+
+   re_search() first tries matching at index START, then it tries to match
+   starting from index START + 1, and so on.  The last start position tried
+   is START + RANGE.  (Thus RANGE = 0 forces re_search to operate the same
+   way as re_match().)
+
+   The parameter STOP of re_{match,search}_2 specifies that no match exceeding
+   the first STOP characters of the concatenation of the strings should be
+   concerned.
+
+   If REGS is not NULL, and BUFP->no_sub is not set, the offsets of the match
+   and all groups is stored in REGS.  (For the "_2" variants, the offsets are
+   computed relative to the concatenation, not relative to the individual
+   strings.)
+
+   On success, re_match* functions return the length of the match, re_search*
+   return the position of the start of the match.  They return -1 on

+/* Set up the following warnings, based on which modules are in use.
+   GNU Coding Standards discourage the use of fseek, since it imposes
+   an arbitrary limitation on some 32-bit hosts.  Remember that the
+   fseek module depends on the fseeko module, so we only have three
+   cases to consider:
+
+   1. The developer is not using either module.  Issue a warning under
+   GNULIB_POSIXCHECK for both functions, to remind them that both
+   functions have bugs on some systems.  _GL_NO_LARGE_FILES has no
+   impact on this warning.
+
+   2. The developer is using both modules.  They may be unaware of the
+   arbitrary limitations of fseek, so issue a warning under
+   GNULIB_POSIXCHECK.  On the other hand, they may be using both
+   modules intentionally, so the developer can define
+   _GL_NO_LARGE_FILES in the compilation units where the use of fseek
+   is safe, to silence the warning.
+
+   3. The developer is using the fseeko module, but not fseek.  Gnulib
+   guarantees that fseek will still work around platform bugs in that
+   case, but we presume that the developer is aware of the pitfalls of
+   fseek and was trying to avoid it, so issue a warning even when
+   GNULIB_POSIXCHECK is undefined.  Again, _GL_NO_LARGE_FILES can be
+   defined to silence the warning in particular compilation units.
+   In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
+   fseek gets defined as a macro, it is recommended that the developer
+   uses the fseek module, even if he is not calling the fseek function.
+
+   Most gnulib clients that perform stream operations should fall into

+
+   A critical factorization has the property that the local period
+   equals the global period.  All strings have at least one critical
+   factorization with the left half smaller than the global period.
+   And while some strings have more than one critical factorization,
+   it is provable that with an ordered alphabet, at least one of the
+   critical factorizations corresponds to a maximal suffix.
+
+   Given an ordered alphabet, a critical factorization can be computed

+/* Each of these macros verifies that its argument R is nonzero.  To
+   be portable, R should be an integer constant expression.  Unlike
+   assert (R), there is no run-time overhead.
+
+   If _Static_assert works, verify (R) uses it directly.  Similarly,
+   _GL_VERIFY_TRUE works by packaging a _Static_assert inside a struct
+   that is an operand of sizeof.
+
+   The code below uses several ideas for C++ compilers, and for C
+   compilers that do not support _Static_assert:
+
+   * The first step is ((R) ? 1 : -1).  Given an expression R, of
+     integral or boolean or floating-point type, this yields an
+     expression of integral type, whose value is later verified to be
+     constant and nonnegative.
+
+   * Next this expression W is wrapped in a type
+     struct _gl_verify_type {
+       unsigned int _gl_verify_error_if_negative: W;
+     }.
+     If W is negative, this yields a compile-time error.  No compiler can
+     deal with a bit-field of negative size.
+
+     One might think that an array size check would have the same
+     effect, that is, that the type struct { unsigned int dummy[W]; }
+     would work as well.  However, inside a function, some compilers
+     (such as C++ compilers and GNU C) allow local parameters and
+     variables inside array size expressions.  With these compilers,
+     an array size check would not properly diagnose this misuse of
+     the verify macro:
+
+       void function (int n) { verify (n < 0); }
+
+   * For the verify macro, the struct _gl_verify_type will need to
+     somehow be embedded into a declaration.  To be portable, this
+     declaration must declare an object, a constant, a function, or a
+     typedef name.  If the declared entity uses the type directly,
+     such as in
+
+       struct dummy {...};
+       typedef struct {...} dummy;
+       extern struct {...} *dummy;
+       extern void dummy (struct {...} *);
+       extern struct {...} *dummy (void);
+
+     two uses of the verify macro would yield colliding declarations
+     if the entity names are not disambiguated.  A workaround is to
+     attach the current line number to the entity name:
+
+       #define _GL_CONCAT0(x, y) x##y
+       #define _GL_CONCAT(x, y) _GL_CONCAT0 (x, y)
+       extern struct {...} * _GL_CONCAT (dummy, __LINE__);
+
+     But this has the problem that two invocations of verify from
+     within the same macro would collide, since the __LINE__ value
+     would be the same for both invocations.  (The GCC __COUNTER__
+     macro solves this problem, but is not portable.)
+
+     A solution is to use the sizeof operator.  It yields a number,
+     getting rid of the identity of the type.  Declarations like
+
+       extern int dummy [sizeof (struct {...})];
+       extern void dummy (int [sizeof (struct {...})]);
+       extern int (*dummy (void)) [sizeof (struct {...})];
+
+     can be repeated.
+
+   * Should the implementation use a named struct or an unnamed struct?
+     Which of the following alternatives can be used?
+
+       extern int dummy [sizeof (struct {...})];
+       extern int dummy [sizeof (struct _gl_verify_type {...})];
+       extern void dummy (int [sizeof (struct {...})]);
+       extern void dummy (int [sizeof (struct _gl_verify_type {...})]);
+       extern int (*dummy (void)) [sizeof (struct {...})];
+       extern int (*dummy (void)) [sizeof (struct _gl_verify_type {...})];
+
+     In the second and sixth case, the struct type is exported to the
+     outer scope; two such declarations therefore collide.  GCC warns
+     about the first, third, and fourth cases.  So the only remaining
+     possibility is the fifth case:
+
+       extern int (*dummy (void)) [sizeof (struct {...})];
+
+   * GCC warns about duplicate declarations of the dummy function if
+     -Wredundant-decls is used.  GCC 4.3 and later have a builtin
+     __COUNTER__ macro that can let us generate unique identifiers for
+     each dummy function, to suppress this warning.
+
+   * This implementation exploits the fact that older versions of GCC,
+     which do not support _Static_assert, also do not warn about the
+     last declaration mentioned above.
+
+   * GCC warns if -Wnested-externs is enabled and 'verify' is used
+     within a function body; but inside a function, you can always
+     arrange to use verify_expr instead.
+
+   * In C++, any struct definition inside sizeof is invalid.
+     Use a template type to work around the problem.  */

+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+   for FUNCTION which will then trigger a compiler warning containing
+   the text of "literal string" anywhere that function is called, if
+   supported by the compiler.  If the compiler does not support this
+   feature, the macro expands to an unused extern declaration.
+
+   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
+   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
+   this feature, it expands to empty.
+
+   These macros are useful for marking a function as a potential
+   portability trap, with the intent that "literal string" include
+   instructions on the replacement function that should be used
+   instead.
+   _GL_WARN_ON_USE is for functions with 'extern' linkage.
+   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
+   linkage.
+
+   However, one of the reasons that a function is a portability trap is
+   if it has the wrong signature.  Declaring FUNCTION with a different
+   signature in C is a compilation error, so this macro must use the
+   same type as any existing declaration so that programs that avoid
+   the problematic FUNCTION do not fail to compile merely because they
+   included a header that poisoned the function.  But this implies that
+   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
+   have a declaration.  Use of this macro implies that there must not
+   be any other macro hiding the declaration of FUNCTION; but
+   undefining FUNCTION first is part of the poisoning process anyway
+   (although for symbols that are provided only via a macro, the result
+   is a compilation error rather than a warning containing
+   "literal string").  Also note that in C++, it is only safe to use if
+   FUNCTION has no overloads.
+
+   For an example, it is possible to poison 'getline' by:
+   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
+     [getline]) in configure.ac, which potentially defines
+     HAVE_RAW_DECL_GETLINE
+   - adding this code to a header that wraps the system <stdio.h>:
+     #undef getline
+     #if HAVE_RAW_DECL_GETLINE
+     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+       "not universally present; use the gnulib module getline");
+     #endif
+
+   It is not possible to directly poison global variables.  But it is
+   possible to write a wrapper accessor function, and poison that
+   (less common usage, like &environ, will cause a compilation error
+   rather than issue the nice warning, but the end result of informing
+   the developer about their portability problem is still achieved):
+     #if HAVE_RAW_DECL_ENVIRON
+     static char ***
+     rpl_environ (void) { return &environ; }
+     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
+     # undef environ
+     # define environ (*rpl_environ ())
+     #endif
+   or better (avoiding contradictory use of 'static' and 'extern'):
+     #if HAVE_RAW_DECL_ENVIRON
+     static char ***
+     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
+     rpl_environ (void) { return &environ; }

+
+   Repeated reallocations are guaranteed to make progress, either by

+
+   This causes x2nrealloc to allocate a block of some nonzero size the
+   first time it is called.
+
+   To have finer-grained control over the initial size, set *PN to a
+   nonzero value before calling this function with P == NULL.  For
+   example:
+
+     int *p = NULL;
+     size_t used = 0;
+     size_t allocated = 0;
+     size_t allocated1 = 1000;

+/* The size of memory objects is often computed through expressions of
+   type size_t. Example:
+      void* p = malloc (header_size + n * element_size).
+   These computations can lead to overflow.  When this happens, malloc()
+   returns a piece of memory that is way too small, and the program then
+   crashes while attempting to fill the memory.
+   To avoid this, the functions and macros in this file check for overflow.
+   The convention is that SIZE_MAX represents overflow.
+   malloc (SIZE_MAX) is not guaranteed to fail -- think of a malloc
+   implementation that uses mmap --, it's recommended to use size_overflow_p()
+   or size_in_bounds_p() before invoking malloc().
+   The example thus becomes:
+      size_t size = xsum (header_size, xtimes (n, element_size));

+# LIBCURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION],
+#                       [ACTION-IF-YES], [ACTION-IF-NO])
+# ----------------------------------------------------------
+#      David Shaw <dshaw@jabberwocky.com>   May-09-2006
+#
+# Checks for libcurl.  DEFAULT-ACTION is the string yes or no to
+# specify whether to default to --with-libcurl or --without-libcurl.
+# If not supplied, DEFAULT-ACTION is yes.  MINIMUM-VERSION is the
+# minimum version of libcurl to accept.  Pass the version as a regular
+# version number like 7.10.1. If not supplied, any version is
+# accepted.  ACTION-IF-YES is a list of shell commands to run if
+# libcurl was successfully found and passed the various tests.
+# ACTION-IF-NO is a list of shell commands that are run otherwise.
+# Note that using --without-libcurl does run ACTION-IF-NO.
+#
+# This macro #defines HAVE_LIBCURL if a working libcurl setup is
+# found, and sets @LIBCURL@ and @LIBCURL_CPPFLAGS@ to the necessary
+# values.  Other useful defines are LIBCURL_FEATURE_xxx where xxx are
+# the various features supported by libcurl, and LIBCURL_PROTOCOL_yyy
+# where yyy are the various protocols supported by libcurl.  Both xxx
+# and yyy are capitalized.  See the list of AH_TEMPLATEs at the top of
+# the macro for the complete list of possible defines.  Shell
+# variables $libcurl_feature_xxx and $libcurl_protocol_yyy are also
+# defined to 'yes' for those features and protocols that were found.
+# Note that xxx and yyy keep the same capitalization as in the
+# curl-config list (e.g. it's "HTTP" and not "http").
+#
+# Users may override the detected values by doing something like:
+# LIBCURL="-lcurl" LIBCURL_CPPFLAGS="-I/usr/myinclude" ./configure
+#
+# For the sake of sanity, this macro assumes that any libcurl that is
+# found is after version 7.7.2, the first version that included the
+# curl-config script.  Note that it is very important for people
+# packaging binary versions of libcurl to include this script!
+# Without curl-config, we can only guess what protocols are available,
+# or use curl_version_info to figure it out at runtime.

+# Checks for uriparser library.  DEFAULT-ACTION is the string yes or no to

+# If not supplied, DEFAULT-ACTION is yes.  MINIMUM-VERSION is the
+# minimum version of uriparser to accept.  Pass the version as a regular

+# accepted.  ACTION-IF-YES is a list of shell commands to run if
+# uriparser was successfully found and passed the various tests.
+# ACTION-IF-NO is a list of shell commands that are run otherwise.
+# Note that using --without-uriparser does run ACTION-IF-NO.

+* Copyright (c) 2008 Monitoring Plugins Development Team
+* 
+* Description:
+* 
+* This file contains the pst3 executable. This is a replacement ps command
+* for Solaris to get output which provides a long argument listing, which
+* is not possible with the standard ps command (due to truncation). /usr/ucb/ps
+* also has issues where some fields run into each other.
+* 
+* This executable works by reading process address structures, so needs
+* to be executed as root
+*
+* Originally written by R.W.Ingraham
+* Rewritten by Duncan Ferguson (Altinity Ltd, June 2008)
+*   The rewrite was necessary as /dev/kmem is not available within
+*   non-global zones on Solaris 10
+*
+*   Details for rewrite came from
+*    source of /usr/ucb/ps on Solaris:
+*     http://cvs.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/ucbcmd/ps/ps.c#argvoff

+#
+# Log file pattern detector plugin for monitoring
+# Written originally by Ethan Galstad (nagios@nagios.org)
+#
+# Usage: ./check_log <log_file> <old_log_file> <pattern>
+#
+# Description:
+#
+# This plugin will scan a log file (specified by the <log_file> option)
+# for a specific pattern (specified by the <pattern> option).  Successive
+# calls to the plugin script will only report *new* pattern matches in the
+# log file, since an copy of the log file from the previous run is saved
+# to <old_log_file>.
+#
+# Output:
+#
+# On the first run of the plugin, it will return an OK state with a message
+# of "Log check data initialized".  On successive runs, it will return an OK
+# state if *no* pattern matches have been found in the *difference* between the
+# log file and the older copy of the log file.  If the plugin detects any
+# pattern matches in the log diff, it will return a CRITICAL state and print
+# out a message is the following format: "(x) last_match", where "x" is the
+# total number of pattern matches found in the file and "last_match" is the
+# last entry in the log file which matches the pattern.
+#
+# Notes:
+#
+# If you use this plugin make sure to keep the following in mind:
+#
+#    1.  The "max_attempts" value for the service should be 1, as this will
+#        prevent the monitoring system from retrying the service check (the
+#        next time the check is run it will not produce the same results).
+#
+#    2.  The "notify_recovery" value for the service should be 0, so that the
+#        monitoring system does not notify you of "recoveries" for the check.
+#        Since pattern matches in the log file will only be reported once and
+#        not the next time, there will always be "recoveries" for the service,
+#        even though recoveries really don't apply to this type of check.
+#
+#    3.  You *must* supply a different <old_file_log> for each service that
+#        you define to use this plugin script - even if the different services
+#        check the same <log_file> for pattern matches.  This is necessary
+#        because of the way the script operates.
+#
+#    4.  This plugin does NOT have an understanding of logrotation or similar
+#        mechanisms. Therefore bad timing could lead to missing events
+#
+#
+# Examples:
+#
+# Check for login failures in the syslog...
+#
+#   check_log /var/log/messages ./check_log.badlogins.old "LOGIN FAILURE"
+#
+# Check for port scan alerts generated by Psionic's PortSentry software...
+#
+#   check_log /var/log/message ./check_log.portscan.old "attackalert"
+#
+
+# Paths to commands used in this script.  These
+# may have to be modified to match your system setup.

+		 the counter unit - that is, the dimensions of the counter you're getting. Examples:
+		 pages/s, packets transferred, etc.
+
+		4) If you want, you may provide the minimum and maximum values to expect. They aren't mandatory,

+* checking the offset with the sync peer, the jitter and stratum. This
+* plugin will not check the clock offset between the local host and NTP
+* server; please use check_ntp_time for that purpose.

+* Care has been taken to make sure the functions are async-safe. The one
+* function which isn't is np_runcmd_init() which it doesn't make sense to
+* call twice anyway, so the api as a whole should be considered async-safe.

+NAME
+     tap -- write tests that implement the Test Anything Protocol
+
+SYNOPSIS
+     #include <tap.h>
+
+DESCRIPTION
+     The tap library provides functions for writing test scripts that produce
+     output consistent with the Test Anything Protocol.  A test harness that
+     parses this protocol can run these tests and produce useful reports indi-
+     cating their success or failure.

+#	Expects a file called install_order, containing one line per distribution name
+#	Will take action against each distribution in turn
+#	-d is a necessary destination directory for the perl mods
+#	If -c is set, will remove the module build directories and exit
+# If -e is set, will extract module
+#	If -m is set, will run perl Makefile.PL and make
+#	If -t is set, will run make test
+#	If -i is set, will run make install
+# If -s <section> specified will only work on that section in the
+#    install_order file - defaults to first section only
+#	Options are discrete. This is because an overall ./configure, make, make test, make install
+#	are run in different invocations. Obviously, you can't run a -t without a -m, but there's no
