+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year  name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+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.

+
+BUILDING
+--------
+
+Jump into the github cloned directory
+
+```
+cd rtorrent
+```
+
+## Install build dependencies
+
+Install [libtorrent](https://github.com/rakshasa/libtorrent) with the same version rTorrent.
+
+Generate configure scripts:
+
+```
+autoreconf -ivf
+```
+
+Optionally, generate man pages:
+
+```
+docbook2man rtorrent.1.xml
+```
+
+Man pages output to "doc/rtorrent.1".
+
+RTorrent follows the development of [libtorrent](https://github.com/rakshasa/libtorrent) closely, and thus the versions must be in sync.
+
+## USAGE
+
+Refer to User Guide: https://github.com/rakshasa/rtorrent/wiki/User-Guide
+
+## LICENSE
+
+GNU GPL, see COPYING. "libtorrent/src/utils/sha_fast.{cc,h}" is
+originally from the Mozilla NSS and is under a triple license; MPL,
+LGPL and GPL. An exception to non-NSS code has been added for linking to OpenSSL as requested by Debian, though the author considers that library to be part of the Operative System and thus linking is allowed according to the GPL.
+
+Use whatever fits your purpose, the code required to compile with
+Mozilla's NSS implementation of SHA1 has been retained and can be
+compiled if the user wishes to avoid using OpenSSL.

+
+  <para>
+    This is the user FAQ for Rakshasa's BitTorrent client. RTorrent is
+    an ncurses based client that uses libTorrent and is written in
+    C++. Efficiency and good code is the main goal of both projects.

+        Use the backspace key to enter file input mode. The bottom
+        line will change into a prompt which allows you to enter URL's

+      </para></question>
+      <answer><para>
+        The torrent data the library received was not a valid torrent
+        file. If this was a direct http download, try downloading the
+        torrent file and add it manually. This usually happens when
+        the torrent link uses some form of redirection that libcurl
+        does not automatically redirect. If the failure still happens,
+        make sure the file is infact an uncorrupted torrent.

+        How does the session feature work?
+      </para></question>
+      <answer><para>
+        When you start the client you can use the "-s" switch to
+        specify a session directory. The client will save all
+        currently running torrents in the session directory and fast
+        resume data will be written when the client exits. Upon
+        restarting the client it will resume all the torrents in the
+        session directory.

+      </para></question>
+      <answer><para>
+        Go into the download view screen and press 't' to initiate a
+        new tracker request. If the tracker requires a minimum timeout
+        between requests you can override this by using the capital
+        'T'. Don't abuse this feature.

+        Why do I sometimes need to press ctrl-Q twice to exit the client?
+      </para></question>
+      <answer><para>
+        The first time you press ctrl-q you initiate the
+        shutdown. This causes rTorrent to send a stop message to the
+        trackers of each torrent, and if the tracker is slow it might
+        take more than a few seconds or until the requests time
+        out. The second time ctrl-q is pressed forces the client to
+        shutdown.

+      <answer><para>
+        Perhaps your terminal sends a different key-code to the
+        application. There's no configuration files for keys yet, so
+        modify rtorrent/src/ui/root.cc:56 to use whatever key you want

+      <answer><para>
+        Make sure you arn't using "-fomit-frame-pointer" when

+        bad code for C++ exception handling. If this doesn't help, run

+## Introduction
+
+## Make a new ip table
+
+    ip_tables.insert_table = <table_name>
+
+Create a new empty table with the name ’table\_name’, with the default
+value returned being $0$.
+
+There is currently no use of the generic ip tables commands.
+
+## Add a new address block
+
+    ip_tables.add_address = <table_name>, 10.0.0.0/8, <value>
+
+Set <value\> for all addresses in the address block, overwriting prior
+values.
+
+## Add a new address block
+
+    ip_tables.load = <table_name>, ~/foo.txt, <value>
+
+Set <value\> for all addresses in the file ’foo.txt’ separated by
+newline, similar to ’add\_address’.
+
+## Get value for address
+
+    ip_tables.get = <table_name>, 10.10.10.10
+
+Returns the value set for an address, or the address block it belongs
+to. The default is $0$.
+
+## Size of data structures
+
+    ip_tables.size_data = <table_name>
+
+Returns the size in bytes of all data structures for this table,
+excluding the root class object itself. Note that the in-memory table is
+dynamically consolidated, as such memory use will always be based on
+actual fragmentation.
+
+The table is a b-tree with 1024 nodes per branch.

+is started, and will stop 15-30 minutes after the last non-private torrent is
+stopped (or when rTorrent quits). For DHT to work, a session directory must be set (for
+saving the DHT cache).
+.TP
+\fBdht_port = \fInumber\fB\fR
+Set the UDP listen port for DHT. Defaults to 6881.
+.TP
+\fBdht_add_node = \fIhost[:port]\fB\fR
+Not intended for use in the configuration file but as one-time option in the
+client or on the command line to bootstrap an empty DHT node table. Contacts 
+the given node and attempts to bootstrap from it if it replies.
+The port is optional, with port 6881 being used by default.
+.TP
+\fBhttp_capath = \fIpath\fB\fR
+.TP
+\fBhttp_cacert = \fIfilename\fB\fR
+Set the certificates to use in http requests. See Curl's
+CURLOPT_CAPATH and CURLOPT_CAINFO options for further information.

+.PP
+Display related settings.
+.TP
+\fBview_add = \fIname\fB\fR
+Create a new view.
+.TP
+\fBview_sort = \fIname\fB\fR
+.TP
+\fBview_sort = \fIname\fB,\fIseconds\fB\fR
+Sort a view according the the criteria set by
+\fBview_sort_current\fR\&. If the optional argument is
+supplied, the view is not sorted if a change happened during the last
+\fBseconds\fR\&. This command is meant to be used with
+\fBschedule\fR\&.
+.TP
+\fBview_sort_new = \fIname\fB,\fI\&...\fB\fR
+.TP
+\fBview_sort_current = \fIname\fB,\fI\&...\fB\fR
+Set the sorting criteria for when new elements inserted or
+\fBview_sort\fR is called. The list can contain any
+number of criteria, including zero, from the following:
+
+\fBname\fR, \fBname_reverse\fR,
+\fBstopped\fR, \fBstarted\fR,
+\fBcomplete\fR, \fBincomplete\fR,
+\fBstate_changed\fR,
+\fBstate_changed_reverse\fR
+.TP
+\fBkey_layout = \fIqwerty|azerty|qwertz|dvorak\fB\fR

+.SH "FILE-SYSTEM SETTINGS"
+.PP
+File-system related settings.
+.TP
+\fBmax_file_size = \fIsize\fB\fR
+Set the maximum size a file can have. Disable by
+passing \fB-1\fR\&.
+.TP
+\fBsplit_file_size = \fIsize\fB\fR
+Split files in a torrent larger than \fBsize\fR into
+seperate files. Disable by passing \fB-1\fR\&.
+.TP
+\fBsplit_suffix = \fIstring\fB\fR
+Set the suffix used on split files. Defaults
+to \fB\&.part\fR\&.
+.SH "DOWNLOAD SETTINGS"

+Settings that require a download as a target, the options need to be
+called through f.ex \fBon_finished\fR\&.
+.TP
+\fBcreate_link = \fItype\fB,\fIpath\fB,\fIsuffix\fB\fR
+.TP
+\fBdelete_link = \fItype\fB,\fIpath\fB,\fIsuffix\fB\fR
+Create or delete a symbolic link. The link path is the concatenation
+of \fBpath\fR, the result of
+the \fBtype\fR on the download,
+and \fBsuffix\fR\&.
+
+Available types are; \fBbase_path\fR uses the base path
+of the download, \fBbase_filename\fR uses the base
+filename of the download, \fBtied\fR uses the path of
+the file the download is tied to, see \fBstart_tied\fR\&.
+.SH "ADVANCED SETTINGS"
+.PP
+This list contains settings users shouldn't need to touch, some may
+even cause crashes or similar if incorrectly set.
+.TP
+\fBhash_read_ahead = \fIMB\fB\fR
+Configure how far ahead we ask the kernel to read when doing hash
+checking. The hash checker uses madvise(..., MADV_WILLNEED) for the

+Number of attempts to check the hash while using the mincore status,
+before forcing. Overworked systems might need lower values to get a
+decent hash checking rate.
+.TP
+\fBmax_open_files = \fIvalue\fB\fR
+Number of files to simultaneously keep open. LibTorrent dynamically
+opens and closes files as necessary when mapping files to
+memory. Default is based on sysconf(_SC_OPEN_MAX).
+You probably only think you know what this option does, so don't touch
+it.
+.TP
+\fBmax_open_sockets = \fIvalue\fB\fR
+Number of network sockets to simultaneously keep open. This value is
+set to a reasonable value based on \fBsysconf(_SC_OPEN_MAX)\fR\&.
+.TP
+\fBmax_open_http = \fIvalue\fB\fR
+Number of sockets to simultaneously keep open. This value is set
+to \fB32\fR by default.
+.TP
+\fBmax_memory_usage = \fIbytes\fB\fR
+Set the max amount of memory space used to mapping file chunks. This
+may also be set using \fBulimit -m\fR where 3/4 will be
+allocated to file chunks.
+.TP
+\fBsend_buffer_size = \fIvalue\fB\fR
+.TP
+\fBreceive_buffer_size = \fIvalue\fB\fR
+Adjust the send and receive buffer size for socket.

+by the program.
+.TP
+\fBcwd = \fIdirectory\fB\fR
+Changes the working directory of the process using
+\fBchdir\fR\&.
+.TP
+\fBsession_on_completion = \fIyes\fB\fR
+Controls if the session torrent is saved when a torrent finishes. By
+default on.
+.TP
+\fBsession_lock = \fIyes\fB\fR
+Controls if a lock file is created in the session directory on startup.
+.TP
+\fBsession_save = \fR
+Save the session files for all downloads.
+.TP
+\fBtos = \fIdefault|lowdelay|throughput|reliability|mincost\fB\fR
+.TP
+\fBtos = \fIhex\fB\fR
+Change the TOS of peer connections, by default set to
+\fBthroughput\fR\&. If the option is set to
+\fBdefault\fR then the system default TOS is used. A
+hex value may be used for non-standard settings.
+.TP
+\fBhandshake_log = \fIyes\fB\fR
+Enable logging of the peer handshake. This generates a large number of
+log messages, but may be useful to debug connection problems.

+# SYNOPSIS
+#
+#   AX_CHECK_ZLIB([action-if-found], [action-if-not-found])
+#
+# DESCRIPTION
+#
+#   This macro searches for an installed zlib library. If nothing was
+#   specified when calling configure, it searches first in /usr/local and
+#   then in /usr, /opt/local and /sw. If the --with-zlib=DIR is specified,
+#   it will try to find it in DIR/include/zlib.h and DIR/lib/libz.a. If
+#   --without-zlib is specified, the library is not searched at all.
+#
+#   If either the header file (zlib.h) or the library (libz) is not found,
+#   shell commands 'action-if-not-found' is run. If 'action-if-not-found' is
+#   not specified, the configuration exits on error, asking for a valid zlib
+#   installation directory or --without-zlib.
+#
+#   If both header file and library are found, shell commands
+#   'action-if-found' is run. If 'action-if-found' is not specified, the
+#   default action appends '-I${ZLIB_HOME}/include' to CPFLAGS, appends
+#   '-L$ZLIB_HOME}/lib' to LDFLAGS, prepends '-lz' to LIBS, and calls
+#   AC_DEFINE(HAVE_LIBZ). You should use autoheader to include a definition
+#   for this symbol in a config.h file. Sample usage in a C/C++ source is as
+#   follows:
+#
+#     #ifdef HAVE_LIBZ
+#     #include <zlib.h>
+#     #endif /* HAVE_LIBZ */

+#   AX_PROG_LUA[([MINIMUM-VERSION], [TOO-BIG-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])]
+#   AX_LUA_HEADERS[([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])]

+#
+# DESCRIPTION
+#
+#   Detect a Lua interpreter, optionally specifying a minimum and maximum
+#   version number. Set up important Lua paths, such as the directories in
+#   which to install scripts and modules (shared libraries).
+#
+#   Also detect Lua headers and libraries. The Lua version contained in the
+#   header is checked to match the Lua interpreter version exactly. When
+#   searching for Lua libraries, the version number is used as a suffix.
+#   This is done with the goal of supporting multiple Lua installs (5.1,
+#   5.2, 5.3, and 5.4 side-by-side).
+#
+#   A note on compatibility with previous versions: This file has been
+#   mostly rewritten for serial 18. Most developers should be able to use
+#   these macros without needing to modify configure.ac. Care has been taken
+#   to preserve each macro's behavior, but there are some differences:
+#
+#   1) AX_WITH_LUA is deprecated; it now expands to the exact same thing as
+#   AX_PROG_LUA with no arguments.
+#
+#   2) AX_LUA_HEADERS now checks that the version number defined in lua.h
+#   matches the interpreter version. AX_LUA_HEADERS_VERSION is therefore
+#   unnecessary, so it is deprecated and does not expand to anything.
+#
+#   3) The configure flag --with-lua-suffix no longer exists; the user
+#   should instead specify the LUA precious variable on the command line.
+#   See the AX_PROG_LUA description for details.
+#
+#   Please read the macro descriptions below for more information.
+#
+#   This file was inspired by Andrew Dalke's and James Henstridge's
+#   python.m4 and Tom Payne's, Matthieu Moy's, and Reuben Thomas's ax_lua.m4
+#   (serial 17). Basically, this file is a mash-up of those two files. I
+#   like to think it combines the best of the two!
+#
+#   AX_PROG_LUA: Search for the Lua interpreter, and set up important Lua
+#   paths. Adds precious variable LUA, which may contain the path of the Lua
+#   interpreter. If LUA is blank, the user's path is searched for an
+#   suitable interpreter.
+#
+#   Optionally a LUAJIT option may be set ahead of time to look for and
+#   validate a LuaJIT install instead of PUC Lua. Usage might look like:
+#
+#     AC_ARG_WITH(luajit, [AS_HELP_STRING([--with-luajit],
+#         [Prefer LuaJIT over PUC Lua, even if the latter is newer. Default: no])
+#     ])
+#     AM_CONDITIONAL([LUAJIT], [test "x$with_luajit" != 'xno'])
+#
+#   If MINIMUM-VERSION is supplied, then only Lua interpreters with a
+#   version number greater or equal to MINIMUM-VERSION will be accepted. If
+#   TOO-BIG-VERSION is also supplied, then only Lua interpreters with a
+#   version number greater or equal to MINIMUM-VERSION and less than
+#   TOO-BIG-VERSION will be accepted.
+#
+#   The Lua version number, LUA_VERSION, is found from the interpreter, and
+#   substituted. LUA_PLATFORM is also found, but not currently supported (no
+#   standard representation).
+#
+#   Finally, the macro finds four paths:
+#
+#     luadir             Directory to install Lua scripts.
+#     pkgluadir          $luadir/$PACKAGE
+#     luaexecdir         Directory to install Lua modules.
+#     pkgluaexecdir      $luaexecdir/$PACKAGE
+#
+#   These paths are found based on $prefix, $exec_prefix, Lua's
+#   package.path, and package.cpath. The first path of package.path
+#   beginning with $prefix is selected as luadir. The first path of
+#   package.cpath beginning with $exec_prefix is used as luaexecdir. This
+#   should work on all reasonable Lua installations. If a path cannot be
+#   determined, a default path is used. Of course, the user can override
+#   these later when invoking make.
+#
+#     luadir             Default: $prefix/share/lua/$LUA_VERSION
+#     luaexecdir         Default: $exec_prefix/lib/lua/$LUA_VERSION
+#
+#   These directories can be used by Automake as install destinations. The
+#   variable name minus 'dir' needs to be used as a prefix to the
+#   appropriate Automake primary, e.g. lua_SCRIPS or luaexec_LIBRARIES.
+#
+#   If an acceptable Lua interpreter is found, then ACTION-IF-FOUND is
+#   performed, otherwise ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-
+#   FOUND is blank, then it will default to printing an error. To prevent
+#   the default behavior, give ':' as an action.
+#
+#   AX_LUA_HEADERS: Search for Lua headers. Requires that AX_PROG_LUA be
+#   expanded before this macro. Adds precious variable LUA_INCLUDE, which
+#   may contain Lua specific include flags, e.g. -I/usr/include/lua5.1. If
+#   LUA_INCLUDE is blank, then this macro will attempt to find suitable
+#   flags.
+#
+#   LUA_INCLUDE can be used by Automake to compile Lua modules or
+#   executables with embedded interpreters. The *_CPPFLAGS variables should
+#   be used for this purpose, e.g. myprog_CPPFLAGS = $(LUA_INCLUDE).
+#
+#   This macro searches for the header lua.h (and others). The search is
+#   performed with a combination of CPPFLAGS, CPATH, etc, and LUA_INCLUDE.
+#   If the search is unsuccessful, then some common directories are tried.
+#   If the headers are then found, then LUA_INCLUDE is set accordingly.
+#
+#   The paths automatically searched are:
+#
+#     * /usr/include/luaX.Y
+#     * /usr/include/lua/X.Y
+#     * /usr/include/luaXY
+#     * /usr/local/include/luaX.Y
+#     * /usr/local/include/lua-X.Y
+#     * /usr/local/include/lua/X.Y
+#     * /usr/local/include/luaXY
+#
+#   (Where X.Y is the Lua version number, e.g. 5.1.)
+#
+#   The Lua version number found in the headers is always checked to match
+#   the Lua interpreter's version number. Lua headers with mismatched
+#   version numbers are not accepted.
+#
+#   If headers are found, then ACTION-IF-FOUND is performed, otherwise
+#   ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then
+#   it will default to printing an error. To prevent the default behavior,
+#   set the action to ':'.
+#
+#   AX_LUA_LIBS: Search for Lua libraries. Requires that AX_PROG_LUA be
+#   expanded before this macro. Adds precious variable LUA_LIB, which may
+#   contain Lua specific linker flags, e.g. -llua5.1. If LUA_LIB is blank,

+#
+#   LUA_LIB can be used by Automake to link Lua modules or executables with

+#   This macro searches for the Lua library. More technically, it searches
+#   for a library containing the function lua_load. The search is performed
+#   with a combination of LIBS, LIBRARY_PATH, and LUA_LIB.
+#
+#   If the search determines that some linker flags are missing, then those
+#   flags will be added to LUA_LIB.
+#
+#   If libraries are found, then ACTION-IF-FOUND is performed, otherwise
+#   ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then
+#   it will default to printing an error. To prevent the default behavior,
+#   set the action to ':'.
+#
+#   AX_LUA_READLINE: Search for readline headers and libraries. Requires the
+#   AX_LIB_READLINE macro, which is provided by ax_lib_readline.m4 from the
+#   Autoconf Archive.
+#
+#   If a readline compatible library is found, then ACTION-IF-FOUND is
+#   performed, otherwise ACTION-IF-NOT-FOUND is performed.

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

+# SYNOPSIS
+#
+#   AX_WITH_CURSES
+#
+# DESCRIPTION
+#
+#   This macro checks whether a SysV or X/Open-compatible Curses library is
+#   present, along with the associated header file.  The NcursesW
+#   (wide-character) library is searched for first, followed by Ncurses,
+#   then the system-default plain Curses.  The first library found is the
+#   one returned. Finding libraries will first be attempted by using
+#   pkg-config, and should the pkg-config files not be available, will
+#   fallback to combinations of known flags itself.
+#
+#   The following options are understood: --with-ncursesw, --with-ncurses,
+#   --without-ncursesw, --without-ncurses.  The "--with" options force the
+#   macro to use that particular library, terminating with an error if not
+#   found.  The "--without" options simply skip the check for that library.
+#   The effect on the search pattern is:
+#
+#     (no options)                           - NcursesW, Ncurses, Curses
+#     --with-ncurses     --with-ncursesw     - NcursesW only [*]
+#     --without-ncurses  --with-ncursesw     - NcursesW only [*]
+#                        --with-ncursesw     - NcursesW only [*]
+#     --with-ncurses     --without-ncursesw  - Ncurses only [*]
+#     --with-ncurses                         - NcursesW, Ncurses [**]
+#     --without-ncurses  --without-ncursesw  - Curses only
+#                        --without-ncursesw  - Ncurses, Curses
+#     --without-ncurses                      - NcursesW, Curses
+#
+#   [*]  If the library is not found, abort the configure script.
+#
+#   [**] If the second library (Ncurses) is not found, abort configure.
+#
+#   The following preprocessor symbols may be defined by this macro if the
+#   appropriate conditions are met:
+#
+#     HAVE_CURSES             - if any SysV or X/Open Curses library found
+#     HAVE_CURSES_ENHANCED    - if library supports X/Open Enhanced functions
+#     HAVE_CURSES_COLOR       - if library supports color (enhanced functions)
+#     HAVE_CURSES_OBSOLETE    - if library supports certain obsolete features
+#     HAVE_NCURSESW           - if NcursesW (wide char) library is to be used
+#     HAVE_NCURSES            - if the Ncurses library is to be used
+#
+#     HAVE_CURSES_H           - if <curses.h> is present and should be used
+#     HAVE_NCURSESW_H         - if <ncursesw.h> should be used
+#     HAVE_NCURSES_H          - if <ncurses.h> should be used
+#     HAVE_NCURSESW_CURSES_H  - if <ncursesw/curses.h> should be used
+#     HAVE_NCURSES_CURSES_H   - if <ncurses/curses.h> should be used
+#
+#   (These preprocessor symbols are discussed later in this document.)
+#
+#   The following output variables are defined by this macro; they are
+#   precious and may be overridden on the ./configure command line:
+#
+#     CURSES_LIBS  - library to add to xxx_LDADD
+#     CURSES_CFLAGS  - include paths to add to xxx_CPPFLAGS
+#
+#   In previous versions of this macro, the flags CURSES_LIB and
+#   CURSES_CPPFLAGS were defined. These have been renamed, in keeping with
+#   AX_WITH_CURSES's close bigger brother, PKG_CHECK_MODULES, which should
+#   eventually supersede the use of AX_WITH_CURSES. Neither the library
+#   listed in CURSES_LIBS, nor the flags in CURSES_CFLAGS are added to LIBS,
+#   respectively CPPFLAGS, by default. You need to add both to the
+#   appropriate xxx_LDADD/xxx_CPPFLAGS line in your Makefile.am. For
+#   example:
+#
+#     prog_LDADD = @CURSES_LIBS@
+#     prog_CPPFLAGS = @CURSES_CFLAGS@
+#
+#   If CURSES_LIBS is set on the configure command line (such as by running
+#   "./configure CURSES_LIBS=-lmycurses"), then the only header searched for
+#   is <curses.h>. If the user needs to specify an alternative path for a
+#   library (such as for a non-standard NcurseW), the user should use the
+#   LDFLAGS variable.
+#
+#   The following shell variables may be defined by this macro:
+#
+#     ax_cv_curses           - set to "yes" if any Curses library found
+#     ax_cv_curses_enhanced  - set to "yes" if Enhanced functions present
+#     ax_cv_curses_color     - set to "yes" if color functions present
+#     ax_cv_curses_obsolete  - set to "yes" if obsolete features present
+#
+#     ax_cv_ncursesw      - set to "yes" if NcursesW library found
+#     ax_cv_ncurses       - set to "yes" if Ncurses library found
+#     ax_cv_plaincurses   - set to "yes" if plain Curses library found
+#     ax_cv_curses_which  - set to "ncursesw", "ncurses", "plaincurses" or "no"
+#
+#   These variables can be used in your configure.ac to determine the level
+#   of support you need from the Curses library.  For example, if you must
+#   have either Ncurses or NcursesW, you could include:
+#
+#     AX_WITH_CURSES
+#     if test "x$ax_cv_ncursesw" != xyes && test "x$ax_cv_ncurses" != xyes; then
+#         AC_MSG_ERROR([requires either NcursesW or Ncurses library])
+#     fi
+#
+#   If any Curses library will do (but one must be present and must support
+#   color), you could use:
+#
+#     AX_WITH_CURSES
+#     if test "x$ax_cv_curses" != xyes || test "x$ax_cv_curses_color" != xyes; then
+#         AC_MSG_ERROR([requires an X/Open-compatible Curses library with color])
+#     fi
+#
+#   Certain preprocessor symbols and shell variables defined by this macro
+#   can be used to determine various features of the Curses library.  In
+#   particular, HAVE_CURSES and ax_cv_curses are defined if the Curses
+#   library found conforms to the traditional SysV and/or X/Open Base Curses
+#   definition.  Any working Curses library conforms to this level.
+#
+#   HAVE_CURSES_ENHANCED and ax_cv_curses_enhanced are defined if the
+#   library supports the X/Open Enhanced Curses definition.  In particular,
+#   the wide-character types attr_t, cchar_t and wint_t, the functions
+#   wattr_set() and wget_wch() and the macros WA_NORMAL and _XOPEN_CURSES
+#   are checked.  The Ncurses library does NOT conform to this definition,
+#   although NcursesW does.
+#
+#   HAVE_CURSES_COLOR and ax_cv_curses_color are defined if the library
+#   supports color functions and macros such as COLOR_PAIR, A_COLOR,
+#   COLOR_WHITE, COLOR_RED and init_pair().  These are NOT part of the
+#   X/Open Base Curses definition, but are part of the Enhanced set of
+#   functions.  The Ncurses library DOES support these functions, as does
+#   NcursesW.
+#
+#   HAVE_CURSES_OBSOLETE and ax_cv_curses_obsolete are defined if the
+#   library supports certain features present in SysV and BSD Curses but not
+#   defined in the X/Open definition.  In particular, the functions
+#   getattrs(), getcurx() and getmaxx() are checked.
+#
+#   To use the HAVE_xxx_H preprocessor symbols, insert the following into
+#   your system.h (or equivalent) header file:
+#
+#     #if defined HAVE_NCURSESW_CURSES_H
+#     #  include <ncursesw/curses.h>
+#     #elif defined HAVE_NCURSESW_H
+#     #  include <ncursesw.h>
+#     #elif defined HAVE_NCURSES_CURSES_H
+#     #  include <ncurses/curses.h>
+#     #elif defined HAVE_NCURSES_H
+#     #  include <ncurses.h>
+#     #elif defined HAVE_CURSES_H
+#     #  include <curses.h>
+#     #else
+#     #  error "SysV or X/Open-compatible Curses header file required"
+#     #endif
+#
+#   For previous users of this macro: you should not need to change anything
