Visual Studio 2012 build fixes

- Fixed VS2012 build issues and crashes on Windows 8 x64
- Added a VS2012 solution to build libjack as a static lib for use with
Visual Studio 2012 projects
- removed unnecessary/outdated binary files that cause crashes and
problems on Win 8

+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006, 2007 Free Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+Briefly, the shell commands `./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.
+
+   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.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. 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.
+
+  6. Often, you can also type `make uninstall' to remove the installed
+     files again.
+
+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 `..'.
+
+   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.
+
+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'.
+
+   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.
+
+   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'.
+
+Optional Features
+=================
+
+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.
+
+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 bug.  Until the bug is fixed you can use this workaround:
+
+     CONFIG_SHELL=/bin/bash /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 the options to `configure', and exit.
+
+`--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.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

windows/tre-0.8.0/NEWS

@@ -0,0 +1,243 @@
+Version 0.8.0
+  - Added tre_ prefix to all functions exported from libtre.  This
+    changes the binary interface (ABI).  The old source interface
+    (API) is still available in <tre/regex.h>.  New programs should
+    use <tre/tre.h>.
+
+  - Visual C++ 6 project files replaced with Visual Studio 2008 files.
+
+  - Bug fixes.
+
+Version 0.7.6
+  - The license is changed from LGPL to a BSD-style license.  The new
+    license is essentially the same as the "2 clause" BSD-style
+    license used in NetBSD.  See the file LICENSE for details.
+
+  - No longer using gnulib due to potential license conflicts.
+
+  - Bug fixes.
+
+Version 0.7.5
+  - Swedish translation added.
+
+  - Makefile and source code distribution problems fixed.
+
+  - Documentation updates.
+
+  - Adding a "+" or "*" after another repetition operator is now an
+    error instead of an application of that operator and gives the
+    REG_BADRPT error.  Adding a "?" means matching as few characters
+    as possible and is still allowed.
+
+    This change was made to avoid confusion with "possessive"
+    (non-backtracking) quantifiers.  In Java (and .NET?) adding a "+"
+    means that the matcher doesn't backtrack over that point.  In
+    previous versions of TRE adding a "+" or "*" caused the
+    backtracking matcher to backtrack a lot more instead of less.  In
+    some cases this caused very slow execution.
+
+  - New agrep command line option -q (--quiet, --silent).
+
+  - Bug fixes:
+    - agrep now correctly returns exit code 1 when no matches found.
+    - Fixed regexp parser bug affecting big-endian 64 bit
+      architectures (sparc, ppc).  The bug caused all regexps to match
+      an empty string and nothing else.
+    - Fixed agrep memory usage problems when reading from pipes.
+
+Version 0.7.4
+
+  - TRE now builds cleanly on x86_64 and other 64 bit platforms.
+    There was a large number of (basically harmless) compiler warnings
+    in previous versions.
+
+  - Now builds and works on Cygwin and MinGW.  Libtool was updated to
+    a version which works on these platforms, and the Makefiles and
+    configure scripts were adjusted so that DLLs are now built on
+    these platforms.
+
+  - agrep now handles long command line options on all platforms.
+
+  - Bug report email address is now tre-general@lists.laurikari.net.
+
+  - Many bug fixes, including:
+    - The RPM spec file now works with recent rpmbuild versions
+    - agrep no longer includes record delimiters in records, so for
+      example "echo foo | agrep 'foo$'" works as expected.
+    - agrep help texts and man page updated.
+
+Version 0.7.3
+  - The license has been changed from GPL to LGPL.
+
+  - New command line option to agrep: --show-position
+
+  - New REG_UNGREEDY cflags and 'U' pattern modifier.
+
+  - Bug fixes.
+
+Version 0.7.2
+  - Bug fixes.
+
+Version 0.7.1
+  - New command line options to agrep: --delimiter-after, --color
+
+  - Man page for agrep added.
+
+  - Some bugs fixed.
+
+Version 0.7.0
+  - reguexec() added.
+
+  - tre_have_backrefs() and tre_have_approx() added.
+
+  - New syntax: \Q, \E, \x1B, \x{263a}, (?inr-inr), (?inr-inr:regex).
+
+  - New compilation flag REG_RIGHT_ASSOC.
+
+  - New execution flags REG_APPROX_MATCHER and REG_BACKTRACKING_MATCHER.
+
+  - Included Python language bindings contributed by Nikolai SAOUKH.
+
+  - Several bugs and compilation problems fixed.
+
+Version 0.6.8
+  - Fixed to use iswctype() if found instead of always using
+    iswalpha() and friends.  Now [[:blank:]] should work again on
+    systems where iswctype() is available.
+
+Version 0.6.7
+  - Fixed the -h (--no-filename) option of agrep to work again.
+
+  - Added the -y option to agrep.  It does nothing, and exists only
+    for compatibility with the non-free version of agrep.
+
+  - Fixed bugs: handling null bytes in multibyte mode, exponential
+    memory usage problem when using lots of macros (e.g. \s or \d) in
+    a regexp, and bugs in expanding {m,n} repeats (still!).
+
+  - wctype() and iswctype() are no longer required for wchar support,
+    iswalpha() and friends will be used instead if wctype() and
+    iswctype() are not found.
+
+  - Added support for compiling against libutf8.
+
+  - Added the tre_config() function to get information about the
+    optional features compiled in the TRE library.  Also added
+    tre_version().
+
+  - Some documentation updates.
+
+Version 0.6.6
+  - Fixed bugs which occurred sometimes when "{m,n}" repeats were used
+    in conjunction with "*", "+", or "?".
+
+  - Added the -H (--with-filename) option to agrep.
+
+Version 0.6.5
+  - Fixed bug which occurred whine several "{m,n}" repeats were used
+    in one regex.
+
+  - Fixed several bugs related to REG_NOSUB or NULL pmatch[] arrays
+    being used for regexec().
+
+  - C++ or Fortran compilers no longer checked by the configure
+    script.
+
+  - Some documentation additions.
+
+Version 0.6.4
+  - Fixed bug in handling iterations (like "+" and "*") inside "{m,n}"
+    repeats.  This should get rid of performance problems and
+    incorrect results with certain regexps involving "{m,n}" repeats.
+
+Version 0.6.3
+  - Fixed back references when REG_NOSUB is used.
+
+  - Compilation errors and warnings fixed.  Now this should compile on
+    systems that don't have wide character support, like OpenBSD, and
+    works on 64 bit machines.
+
+Version 0.6.2
+  - Bug fixes.
+
+Version 0.6.1
+  - Bug fixes.
+
+  - Some documentation updates.
+
+Version 0.6.0
+  - The doc/ directory is now actually included in source
+    distributions (oops).
+
+  - Bug fixes.
+
+  - alloca() is no longer a requirement.  The configure script still
+    looks for it, and it is used if found.
+
+  - New approximate matching syntax.  The new syntax allows
+    approximate matching to be done even using the standard regex API
+    (match costs are only available when the regaexec() API is used).
+
+  - REG_LITERAL implemented.
+
+Version 0.5.3
+  - Bug fixes and compilation fixes.
+
+  - Best match mode (-B) for agrep.
+
+Version 0.5.2
+  - System ABI support.  TRE is now by default configured to be
+    compatible with the system regex binary interface (by including
+    the system regex.h and using the definitions there instead of
+    TRE's own).  This can be disabled with --disable-system-abi.
+
+  - Added a pkg-config file `tre.pc'.
+
+  - Added support for minimal (non-greedy) repetition operators
+    "*?", "+?", "??", and "{m,n}?".  They work similarly to the ones
+    in Perl, except the number of characters matched is minimized
+    instead of the number of repetitions.
+
+  - Added some documentation in the doc/ subdirectory.
+
+  - Bug fixes.
+
+Version 0.5.1
+  - Bug fixes.
+
+Version 0.5.0
+  - Approximate matching functions now fill the pmatch[] array of
+    submatches if wanted.
+
+  - Support for back referencing (not for approximate matching).
+
+  - Changed approximate matching API to be more easily extendible in
+    the future.  The match cost is now returned.
+
+  - Bug fixes.
+
+  - Windows project files (original versions contributed by Aymeric
+    Moizard <jack@atosc.org>, thanks!).
+
+Version 0.4.1
+  - Fixed installed headers.
+
+  - Fixed compilation problems.
+
+Version 0.4.0
+  - The name of the package changed to TRE.
+
+  - New API for approximate regexp matching.
+
+  - New command line utility `agrep' for approximate regexp matching
+    in the style of grep.
+
+  - New translation for Finnish (fi) has been added.
+
+  - Optimizations in regexec.
+
+  - Wide character support and multibyte character set support can be
+    turned off with --disable-wchar and --disable-multibyte,
+    respectively.
+
+  - Lots of bugfixes.

+Introduction
+
+   TRE is a lightweight, robust, and efficient POSIX compliant regexp
+   matching library with some exciting features such as approximate
+   (fuzzy) matching.
+
+   The matching algorithm used in TRE uses linear worst-case time in
+   the length of the text being searched, and quadratic worst-case
+   time in the length of the used regular expression. In other words,
+   the time complexity of the algorithm is O(M^2N), where M is the
+   length of the regular expression and N is the length of the
+   text. The used space is also quadratic on the length of the regex,
+   but does not depend on the searched string. This quadratic
+   behaviour occurs only on pathological cases which are probably very
+   rare in practice.
+
+Features
+
+   TRE is not just yet another regexp matcher. TRE has some features
+   which are not there in most free POSIX compatible
+   implementations. Most of these features are not present in non-free
+   implementations either, for that matter.
+
+Approximate matching
+
+   Approximate pattern matching allows matches to be approximate, that
+   is, allows the matches to be close to the searched pattern under
+   some measure of closeness. TRE uses the edit-distance measure (also
+   known as the Levenshtein distance) where characters can be
+   inserted, deleted, or substituted in the searched text in order to
+   get an exact match. Each insertion, deletion, or substitution adds
+   the distance, or cost, of the match. TRE can report the matches
+   which have a cost lower than some given threshold value. TRE can
+   also be used to search for matches with the lowest cost.
+
+   TRE includes a version of the agrep (approximate grep) command line
+   tool for approximate regexp matching in the style of grep. Unlike
+   other agrep implementations (like the one by Sun Wu and Udi Manber
+   from University of Arizona available here) TRE agrep allows full
+   regexps of any length, any number of errors, and non-uniform costs
+   for insertion, deletion and substitution.
+
+Strict standard conformance
+
+   POSIX defines the behaviour of regexp functions precisely. TRE
+   attempts to conform to these specifications as strictly as
+   possible. TRE always returns the correct matches for subpatterns,
+   for example. Very few other implementations do this correctly. In
+   fact, the only other implementations besides TRE that I am aware of
+   (free or not) that get it right are Rx by Tom Lord, Regex++ by John
+   Maddock, and the AT&T ast regex by Glenn Fowler and Doug McIlroy.
+
+   The standard TRE tries to conform to is the IEEE Std 1003.1-2001,
+   or Open Group Base Specifications Issue 6, commonly referred to as
+   "POSIX".  It can be found online here. The relevant parts are the
+   base specifications on regular expressions (and the rationale) and
+   the description of the regcomp() API.
+
+   For an excellent survey on POSIX regexp matchers, see the testregex
+   pages by Glenn Fowler of AT&T Labs Research.
+
+Predictable matching speed
+
+   Because of the matching algorithm used in TRE, the maximum time
+   consumed by any regexec() call is always directly proportional to
+   the length of the searched string. There is one exception: if back
+   references are used, the matching may take time that grows
+   exponentially with the length of the string. This is because
+   matching back references is an NP complete problem, and almost
+   certainly requires exponential time to match in the worst case.
+
+Predictable and modest memory consumption
+
+   A regexec() call never allocates memory from the heap. TRE
+   allocates all the memory it needs during a regcomp() call, and some
+   temporary working space from the stack frame for the duration of
+   the regexec() call. The amount of temporary space needed is
+   constant during matching and does not depend on the searched
+   string. For regexps of reasonable size TRE needs less than 50K of
+   dynamically allocated memory during the regcomp() call, less than
+   20K for the compiled pattern buffer, and less than two kilobytes of
+   temporary working space from the stack frame during a regexec()
+   call. There is no time/memory tradeoff. TRE is also small in code
+   size; statically linking with TRE increases the executable size
+   less than 30K (gcc-3.2, x86, GNU/Linux).
+
+Wide character and multibyte character set support
+
+   TRE supports multibyte character sets. This makes it possible to
+   use regexps seamlessly with, for example, Japanese locales. TRE
+   also provides a wide character API.
+
+Binary pattern and data support
+
+   TRE provides APIs which allow binary zero characters both in
+   regexps and searched strings. The standard API cannot be easily
+   used to, for example, search for printable words from binary data
+   (although it is possible with some hacking). Searching for patterns
+   which contain binary zeroes embedded is not possible at all with
+   the standard API.
+
+Completely thread safe
+
+   TRE is completely thread safe. All the exported functions are
+   re-entrant, and a single compiled regexp object can be used
+   simultaneously in multiple contexts; e.g. in main() and a signal
+   handler, or in many threads of a multithreaded application.
+
+Portable
+
+   TRE is portable across multiple platforms. Here's a table of
+   platforms and compilers that have been successfully used to compile
+   and run TRE:
+
+      Platform(s)                       | Compiler(s)
+      ----------------------------------+------------
+      AIX 4.3.2 - 5.3.0                 | GCC, C for AIX compiler version 5
+      Compaq Tru64 UNIX V5.1A/B         | Compaq C V6.4-014 - V6.5-011
+      Cygwin 1.3 - 1.5                  | GCC
+      Digital UNIX V4.0                 | DEC C V5.9-005
+      FreeBSD 4 and above               | GCC
+      GNU/Linux systems on x86, x86_64, | GCC

+
+   TRE 0.7.5 should compile without changes on all of the above
+   platforms.  Tell me if you are using TRE on a platform that is not
+   listed above, and I'll add it to the list. Also let me know if TRE
+   does not work on a listed platform.
+
+   Depending on the platform, you may need to install libutf8 to get
+   wide character and multibyte character set support.
+
+ Free
+
+   TRE is released under a license which is essentially the same as
+   the "2 clause" BSD-style license used in NetBSD.  See the file
+   LICENSE for details.
+
+Roadmap
+
+   There are currently two features, both related to collating
+   elements, missing from 100% POSIX compliance. These are:
+
+     * Support for collating elements (e.g. [[.<X>.]], where <X> is a
+       collating element). It is not possible to support
+       multi-character collating elements portably, since POSIX does
+       not define a way to determine whether a character sequence is a
+       multi-character collating element or not.
+
+     * Support for equivalence classes, for example [[=<X>=]], where
+       <X> is a collating element. An equivalence class matches any
+       character which has the same primary collation weight as
+       <X>. Again, POSIX provides no portable mechanism for
+       determining the primary collation weight of a collating
+       element.
+
+   Note that other portable regexp implementations don't support
+   collating elements either. The single exception is Regex++, which
+   comes with its own database for collating elements for different
+   locales. Support for collating elements and equivalence classes has
+   not been widely requested and is not very high on the TODO list at
+   the moment.
+
+   These are other features I'm planning to implement real soon now:
+
+     * All the missing GNU extensions enabled in GNU regex, such as
+       [[:<:]] and [[:>:]]
+
+     * A REG_SHORTEST regexec() flag for returning the shortest match
+       instead of the longest match.
+
+     * Perl-compatible syntax
+
+            [:^class:]
+               Matches anything but the characters in class. Note that
+               [^[:class:]] works already, this would be just a
+               convenience shorthand.
+
+            \A
+               Match only at beginning of string
+
+            \Z
+               Match only at end of string, or before newline at the end

+TODO:
+
+ * Documentation
+
+   - Finish the reference manual of the API.
+   - Finish the manual describing the syntax and semantics of regexps.
+   - Write a description of the algorithms used.  There's already my
+     Master's Thesis, but it's not TRE-specific, and it's a
+     thesis, not an algorithm description.
+   - Write man page for tre regexp syntax.
+
+ * POSIX required features
+
+   - Support for collating elements and equivalence classes.  This
+     requires some level of integration with libc.
+
+ * New features
+
+   - Support for GNU regex extensions.
+     - word boundary syntax [[:<:]] and [[:>:]]
+     - beginning and end of buffer assertions ("\`" and "\'")
+     - is there something else missing?
+   - Better system ABI support for non-glibc systems?
+   - Transposition operation for the approximate matcher?
+
+ * Extend API
+
+   - Real-time interface?
+      - design API
+      - return if not finished after a certain amount of work
+      - easy for regexec(), more work for regcomp().
+
+
+ * Optimizations
+
+   - Make specialized versions of matcher loops for REG_NOSUB.
+
+   - Find out the longest string that must occur in any match, and
+     search for it first (with a fast Boyer-Moore search, or maybe
+     just strstr).  Then match both ways to see if it was part of
+     match.
+
+   - Some kind of a pessimistic histogram filter might speed up
+     searching for approximate matching.
+
+   - Optimize tre_tnfa_run_parallel to be faster (swap instead of
+     copying everything?  Assembler optimizations?)
+
+   - Write a benchmark suite to see whan effects different
+     optimizations have in different situations.

+.TH agrep 1 "November 21, 2004" "TRE agrep @PACKAGE_VERSION@"
+.SH NAME
+agrep \- print lines approximately matching a pattern
+.SH SYNOPSIS
+.B agrep
+.RI [ OPTION ]...
+.I PATTERN
+.RI [ FILE ]...
+.SH DESCRIPTION
+Searches for approximate matches of PATTERN in each FILE or standard
+input.   Example: `agrep \-2 optimize foo.txt' outputs all lines in
+file `foo.txt' that match "optimize" within two errors.  E.g. lines
+which contain "optimise", "optmise", and "opitmize" all match.
+.SH OPTIONS
+.SS "Regexp selection and interpretation:"
+.TP
+.BI \-e " PATTERN" "\fR,\fP \-\^\-regexp=" PATTERN
+Use
+.I PATTERN
+as a regular expression; useful to protect patterns beginning with
+.BR \- .
+.TP
+.BR \-i ", " \-\^\-ignore\-case
+Ignore case distinctions (as defined by the current locale) in
+.I PATTERN
+and input files.
+.TP
+.BR \-k ", " \-\^\-literal
+Treat
+.I PATTERN
+as a literal string, that is, a fixed string with no special
+characters.
+.TP
+.BR \-w ", " \-\^\-word\-regexp
+Force
+.I PATTERN
+to match only whole words.  A "whole word" is a substring which either
+starts at the beginning or the record or is preceded by a non-word
+constituent character.   Similarly, the substring must either end at
+the end of the record or be followed by a non-word constituent
+character.  Word-constituent characters are alphanumerics (as
+defined by the current locale) and the underscore character.  Note
+that the non-word constituent characters
+.B must
+surround the match; they cannot be counted as errors.
+.SS "Approximate matching settings:"
+.TP
+.BI \-D " NUM" "\fR,\fP \-\^\-delete\-cost=" NUM
+Set cost of missing characters to
+.IR NUM .
+.TP
+.BI \-I " NUM" "\fR,\fP \-\^\-insert\-cost=" NUM
+Set cost of extra characters to
+.IR NUM .
+.TP
+.BI \-S " NUM" "\fR,\fP \-\^\-substitute\-cost=" NUM
+Set cost of incorrect characters to
+.IR NUM .
+Note that a deletion (a missing character) and an insertion (an extra
+character) together constitute a substituted character, but the cost
+will be the that of a deletion and an insertion added together.  Thus,
+if the const of a substitution is set to be larger than the sum
+of the costs of deletion and insertion, direct substitutions will
+never be done.
+.TP
+.BI \-E " NUM" "\fR,\fP \-\^\-max\-errors=" NUM
+Select records that have at most
+.I NUM
+errors.
+.TP
+-\fI#\fR
+Select records that have at most \fI#\fR errors (\fI#\fR is a
+digit between 0 and 9).
+.SS "Miscellaneous:"
+.TP
+.BI \-d " PATTERN" "\fR,\fP \-\^\-delimiter=" PATTERN
+Set the record delimiter regular expression to
+.IR PATTERN .
+The text between two delimiters, before the first delimiter, and after
+the last delimiter is considered to be a record.  The default record
+delimiter is the regexp "\\n", so by default a record is a line.
+.I PATTERN
+can be any regular expression that does not match the empty string.
+For example, using
+.B \-d
+"^From "
+defines mail messages as records in a Mailbox format file.
+.TP
+.BR \-v ", " \-\^\-invert\-match
+Select non-matching records instead of matching records.
+.TP
+.BR \-V ", " \-\^\-version
+Print version information and exit.
+.TP
+.BR \-y ", " \-\^\-nothing
+Does nothing.  This options exists only for compatibility with the
+non-free agrep program.
+.TP
+.BR \-\^\-help
+Display a brief help message and exit.
+.SS "Output control:"
+.TP
+.BR \-B ", " \-\^\-best\-match
+Only output the best matching records, that is, the records with the
+lowest cost.  This is currently implemented by making two passes over
+the input files and cannot be used when reading from standard input.
+.TP
+.BR \-\^\-color ", " \-\^\-colour
+Highlight the matching strings in the output with a color marker.  The
+color string is taken from the
+.BI GREP_COLOR
+environment variable.  The default color is red.
+.TP
+.BR \-c ", " \-\^\-count
+Only print a count of matching records per each input file,
+suppressing normal output.
+.TP
+.BR \-h ", " \-\^\-no\-filename
+Suppress the prefixing filename on output when multiple files are
+searched.
+.TP
+.BR \-H ", " \-\^\-with\-filename
+Prefix each output record with the name of the input file where the
+record was read from.
+.TP
+.BR \-l ", " \-\^\-files\-with\-matches
+Only print the name of each input file which contains at least one
+match, suppressing normal output.  The scanning for each file will
+stop on the first match.
+.TP
+.BR \-n ", " \-\^\-record\-number
+Prefix each output record with its sequence number in the input file.
+The number of the first record is 1.
+.TP
+.BR \-q ", " \-\^\-quiet ", " \-\^\-silent
+Do not write anything to standard output.  Exit immediately with zero
+exit status if a match is found.
+.TP
+.BR \-s ", " \-\^\-show\-cost
+Print match cost with output.
+.TP
+.BR \-\^\-show\-position
+Prefix each output record with the start and end offset of the first
+match within the record.  The offset of the first character of the
+record is 0.  The end position is given as the offset of the first
+character after the match.
+.TP
+.BR \-M ", " \-\^\-delimiter\-after
+By default, the record delimiter is the newline character and is
+output after the matching record.  If
+.B \-d
+is used, the record delimiter will be output before the matching
+record.  This option causes the delimiter to be output after the
+matching record.
+.PP
+With no
+.IR FILE ,
+or when
+.I FILE
+is -, reads standard input.  If less than two
+.IR FILE s
+are given
+.B \-h
+is assumed, otherwise
+.B \-H
+is the default.
+.SH DIAGNOSTICS
+Exit status is 0 if a match is found, 1 for no match, and 2 if there
+were errors.  If
+.B \-E
+or -\fI#\fR is not specified, only exact matches are selected.
+.PP
+.I PATTERN
+is a POSIX extended regular expression (ERE) with the TRE extensions.

+The <tt><font class="func">regcomp</font>()</tt> function compiles

+class="arg">regex</font></tt> to an internal representation and
+stores the result in the pattern buffer structure pointed to by
+<tt><font class="arg">preg</font></tt>.  The <tt><font
+class="func">regncomp</font>()</tt> function is like <tt><font
+class="func">regcomp</font>()</tt>, but <tt><font
+class="arg">regex</font></tt> is not terminated with the null
+byte.  Instead, the <tt><font class="arg">len</font></tt> argument
+is used to give the length of the string, and the string may contain
+null bytes.  The <tt><font class="func">regwcomp</font>()</tt> and
+<tt><font class="func">regwncomp</font>()</tt> functions work like
+<tt><font class="func">regcomp</font>()</tt> and <tt><font
+class="func">regncomp</font>()</tt>, respectively, but take a wide
+character (<tt><font class="type">wchar_t</font></tt>) string
+instead of a byte string.

+bytes.  The <tt><font class="func">regwexec</font>()</tt> and
+<tt><font class="func">regwnexec</font>()</tt> functions work like
+<tt><font class="func">regexec</font>()</tt> and <tt><font

+character (<tt><font class="type">wchar_t</font></tt>) string
+instead of a byte string. The <tt><font

+more of the following flags:
+</p>
+<blockquote>
+<dl>
+<dt><code>REG_NOTBOL</code></dt>
+<dd>
+<p>
+When this flag is used, the match-beginning-of-line operator

+<tt><font class="arg">string</font></tt>.  If
+<code>REG_NEWLINE</code> was used when compiling
+<tt><font class="arg">preg</font></tt> the empty string
+immediately after a newline character will still be matched.
+</p>
+</dd>
+
+<dt><code>REG_NOTEOL</code></dt>
+<dd>
+<p>
+When this flag is used, the match-end-of-line operator
+<tt>$</tt> does not match the empty string at the end of
+<tt><font class="arg">string</font></tt>.  If
+<code>REG_NEWLINE</code> was used when compiling
+<tt><font class="arg">preg</font></tt> the empty string
+immediately before a newline character will still be matched.
+</p>
+
+</dl>
+
+<p>
+These flags are useful when different portions of a string are passed
+to <code>regexec</code> and the beginning or end of the partial string
+should not be interpreted as the beginning or end of a line.
+</p>
+
+</blockquote>
+
+<p>
+If <code>REG_NOSUB</code> was used when compiling <tt><font
+class="arg">preg</font></tt>, <tt><font
+class="arg">nmatch</font></tt> is zero, or <tt><font
+class="arg">pmatch</font></tt> is <code>NULL</code>, then the
+<tt><font class="arg">pmatch</font></tt> argument is ignored.
+Otherwise, the submatches corresponding to the parenthesized
+subexpressions are filled in the elements of <tt><font
+class="arg">pmatch</font></tt>, which must be dimensioned to have
+at least <tt><font class="arg">nmatch</font></tt> elements.
+</p>
+
+<p>
+The <tt><font class="type">regmatch_t</font></tt> structure contains
+at least the following fields:
+</p>
+<blockquote>
+<dl>
+<dt><tt><font class="type">regoff_t</font> <font
+class="arg">rm_so</font></tt></dt>
+<dd>Offset from start of <tt><font class="arg">string</font></tt> to start of
+substring.  </dd>
+<dt><tt><font class="type">regoff_t</font> <font
+class="arg">rm_eo</font></tt></dt>
+<dd>Offset from start of <tt><font class="arg">string</font></tt> to the first
+character after the substring.  </dd>
+</dl>
+</blockquote>
+
+<p>
+The length of a submatch can be computed by subtracting <code>rm_eo</code> and
+<code>rm_so</code>.  If a parenthesized subexpression did not participate in a
+match, the <code>rm_so</code> and <code>rm_eo</code> fields for the
+corresponding <code>pmatch</code> element are set to <code>-1</code>.  Note
+that when a multibyte character set is in effect, the submatch offsets are
+given as byte offsets, not character offsets.
+</p>
+
+<p>
+The <code>regexec()</code> functions return zero if a match was found,
+otherwise they return <code>REG_NOMATCH</code> to indicate no match,
+or <code>REG_ESPACE</code> to indicate that enough temporary memory
+could not be allocated to complete the matching operation.

+to the ERE syntax.  A simple Extended Backus-Naur Form (EBNF) style
+notation is used to describe the grammar.

+
+<p>
+An atom followed by <tt>*</tt> matches a sequence of 0 or more matches
+of the atom.  <tt>+</tt> is similar to <tt>*</tt>, matching a sequence
+of 1 or more matches of the atom.  An atom followed by <tt>?</tt>
+matches a sequence of 0 or 1 matches of the atom.
+</p>
+
+<p>
+A <i>bound</i> is one of the following, where <i>m</i> and <i>m</i>

+An atom followed by [1] matches a sequence of <i>m</i> through <i>n</i>
+(inclusive) matches of the atom.  An atom followed by [2]
+matches a sequence of <i>m</i> or more matches of the atom.  An atom
+followed by [3] matches a sequence of exactly <i>m</i> matches of the
+atom.
+</p>
+
+
+<p>
+Adding a <tt>?</tt> to a repeat operator makes the subexpression minimal, or
+non-greedy.  Normally a repeated expression is greedy, that is, it matches as
+many characters as possible.  A non-greedy subexpression matches as few
+characters as possible.  Note that this does not (always) mean the same thing
+as matching as many or few repetitions as possible.  Also note
+that <strong>minimal repetitions are not currently supported for approximate
+matching</strong>.

+The approximate matching settings for a subpattern can be changed
+by appending <i>approx-settings</i> to the subpattern.  Limits for
+the number of errors can be set and an expression for specifying and
+limiting the costs can be given.
+</p>
+
+<p>
+The <i>count-limits</i> can be used to set limits for the number of
+insertions (<tt>+</tt>), deletions (<tt>-</tt>), substitutions
+(<tt>#</tt>), and total number of errors (<tt>~</tt>).  If the
+<i>number</i> part is omitted, the specified error count will be
+unlimited.
+</p>
+
+<p>
+The <i>cost-equation</i> can be thought of as a mathematical equation,
+where <tt>i</tt>, <tt>d</tt>, and <tt>s</tt> stand for the number of
+insertions, deletions, and substitutions, respectively.  The equation
+can have a multiplier for each of <tt>i</tt>, <tt>d</tt>, and
+<tt>s</tt>.  The multiplier is the cost of the error, and the number
+after <tt>&lt;</tt> is the maximum allowed cost of a match.  Spaces
+and pluses can be inserted to make the equation readable.  In fact, when
+specifying only a cost equation, adding a space after the opening <tt>{</tt>
+is <strong>required</strong>.
+</p>
+
+<p>
+Examples:
+<dl>
+<dt><tt>{~}</tt></dt>
+<dd>Sets the maximum number of errors to unlimited.</dd>
+<dt><tt>{~3}</tt></dt>
+<dd>Sets the maximum number of errors to three.</dd>
+<dt><tt>{+2~5}</tt></dt>
+<dd>Sets the maximum number of errors to five, and the maximum number
+of insertions to two.</dd>
+<dt><tt>{&lt;3}</tt></dt>
+<dd>Sets the maximum cost to three.
+<dt><tt>{ 2i + 1d + 2s &lt; 5 }</tt></dt>
+<dd>Sets the cost of an insertion to two, a deletion to one, a
+substitution to two, and the maximum cost to five.

+A bracket expression specifies a set of characters by enclosing a
+nonempty list of items in brackets.  Normally anything matching any
+item in the list is matched.  If the list begins with <tt>^</tt> the
+meaning is negated; any character matching no item in the list is
+matched.
+</p>
+
+<p>
+An item is any of the following:
+</p>
+<ul>
+<li>A single character, matching that character.</li>
+<li>Two characters separated by <tt>-</tt>.  This is shorthand for the
+full range of characters  between those two (inclusive) in the
+collating sequence.  For example, <tt>[0-9]</tt> in ASCII matches any
+decimal digit.</li>
+<li>A collating element enclosed in <tt>[.</tt> and <tt>.]</tt>,
+matching the collating element.  This can be used to include a literal
+<tt>-</tt> or a multi-character collating element in the list.</li>
+<li>A collating element enclosed in <tt>[=</tt> and <tt>=]</tt> (an
+equivalence class), matching all collating elements with the same
+primary collation weight as that element, including the element
+itself.</li>
+<li>The name of a character class enclosed in <tt>[:</tt> and
+<tt>:]</tt>, matching any character belonging to the class.  The set
+of valid names depends on the <code>LC_CTYPE</code> category of the
+current locale, but the following names are valid in all locales:
+<ul>
+<li><tt>alnum</tt> - alphanumeric characters</li>
+<li><tt>alpha</tt> - alphabetic characters</li>
+<li><tt>blank</tt> - blank characters</li>
+<li><tt>cntrl</tt> - control characters</li>
+<li><tt>digit</tt> - decimal digits (0 through 9)</li>
+<li><tt>graph</tt> - all printable characters except space</li>
+<li><tt>lower</tt> - lower-case letters</li>
+<li><tt>print</tt> - printable characters including space</li>
+<li><tt>punct</tt> - printable characters not space or alphanumeric</li>
+<li><tt>space</tt> - white-space characters</li>
+<li><tt>upper</tt> - upper case letters</li>
+<li><tt>xdigit</tt> - hexadecimal digits</li>
+</ul>
+</ul>
+<p>
+To include a literal <tt>-</tt> in the list, make it either the first
+or last item, the second endpoint of a range, or enclose it in
+<tt>[.</tt> and <tt>.]</tt> to make it a collating element.  To
+include a literal <tt>]</tt> in the list, make it either the first
+item, the second endpoint of a range, or enclose it in <tt>[.</tt> and
+<tt>.]</tt>.  To use a literal <tt>-</tt> as the first
+endpoint of a range, enclose it in <tt>[.</tt> and <tt>.]</tt>.

+The expressions <tt>^</tt> and <tt>$</tt> are called "left anchor" and
+"right anchor", respectively.  The left anchor matches the empty
+string at the beginning of the string.  The right anchor matches the
+empty string at the end of the string.  The behaviour of both anchors
+can be varied by specifying certain execution and compilation flags;
+see the <a href="api.html">API manual</a>.
+</p>
+
+<p>
+An assertion-character can be any of the following:
+</p>
+
+<ul>
+<li><tt>&lt;</tt> - Beginning of word
+<li><tt>&gt;</tt> - End of word
+<li><tt>b</tt> - Word boundary
+<li><tt>B</tt> - Non-word boundary
+<li><tt>d</tt> - Digit character (equivalent to <tt>[[:digit:]]</tt>)</li>
+<li><tt>D</tt> - Non-digit character (equivalent to <tt>[^[:digit:]]</tt>)</li>
+<li><tt>s</tt> - Space character (equivalent to <tt>[[:space:]]</tt>)</li>
+<li><tt>S</tt> - Non-space character (equivalent to <tt>[^[:space:]]</tt>)</li>
+<li><tt>w</tt> - Word character (equivalent to <tt>[[:alnum:]_]</tt>)</li>

+<p>
+A literal is either an ordinary character (a character that has no
+other significance in the context), an 8 bit hexadecimal encoded
+character (e.g. <tt>\x1B</tt>), a wide hexadecimal encoded character
+(e.g. <tt>\x{263a}</tt>), or an escaped character.  An escaped
+character is a <tt>\</tt> followed by any character, and matches that
+character.  Escaping can be used to match characters which have a
+special meaning in regexp syntax.  A <tt>\</tt> cannot be the last
+character of an ERE.  Escaping also allows you to include a few
+non-printable characters in the regular expression.  These special
+escape sequences include:
+</p>
+
+<ul>
+<li><tt>\a</tt> - Bell character (ASCII code 7)
+<li><tt>\e</tt> - Escape character (ASCII code 27)
+<li><tt>\f</tt> - Form-feed character (ASCII code 12)
+<li><tt>\n</tt> - New-line/line-feed character (ASCII code 10)
+<li><tt>\r</tt> - Carriage return character (ASCII code 13)
+<li><tt>\t</tt> - Horizontal tab character (ASCII code 9)
+</ul>
+
+<p>
+An ordinary character is just a single character with no other
+significance, and matches that character.  A <tt>{</tt> followed by
+something else than a digit is considered an ordinary character.
+</p>
+
+
+<h3>Back references</h3>
+<a name="backref"></a>
+
+<table bgcolor="#e0e0f0" cellpadding="10">
+<tr><td>
+<pre>
+<i>back-reference</i> ::= <b>"\"</b> [<b>"1"</b>-<b>"9"</b>]
+</pre>
+</td></tr>
+</table>
+<p>
+A back reference is a backslash followed by a single non-zero decimal
+digit <i>d</i>.  It matches the same sequence of characters
+matched by the <i>d</i>th parenthesized subexpression.
+</p>
+
+<p>
+Back references are not defined for POSIX EREs (for BREs they are),
+but many matchers, including TRE, implement back references for both
+EREs and BREs.
+</p>
+
+<h3>Options</h3>
+<a name="options"></a>
+<table bgcolor="#e0e0f0" cellpadding="10">
+<tr><td>
+<pre>
+<i>options</i> ::= [<b>"i" "n" "r" "U"</b>]* (<b>"-"</b> [<b>"i" "n" "r" "U"</b>]*)?
+</pre>
+</td></tr>
+</table>
+
+Options allow compile time options to be turned on/off for particular parts of the
+regular expression. The options equate to several compile time options specified to
+the regcomp API function. If the option is specified in the first section, it is
+turned on. If it is specified in the second section (after the <tt>-</tt>), it is
+turned off.
+<ul>
+<li>i - Case insensitive.
+<li>n - Forces special handling of the new line character. See the REG_NEWLINE flag in
+the <a href="tre-api.html">API Manual</a>.
+<li>r - Causes the regex to be matched in a right associative manner rather than the normal
+left associative manner.
+<li>U - Forces repetition operators to be non-greedy unless a <tt>?</tt> is appended.
+</ul>
+<h2>BRE Syntax</h2>
+
+<p>
+The obsolete basic regexp (BRE) syntax differs from the ERE syntax as
+follows:
+</p>
+
+<ul>
+<li><tt>|</tt> is an ordinary character, and there is no equivalent
+for its functionality.  <tt>+</tt>, and <tt>?</tt> are ordinary
+characters.</li>
+<li>The delimiters for bounds are <tt>\{</tt> and <tt>\}</tt>, with
+<tt>{</tt> and <tt>}</tt> by themselves ordinary characters.</li>
+<li>The parentheses for nested subexpressions are <tt>\(</tt> and
+<tt>\)</tt>, with <tt>(</tt> and <tt>)</tt> by themselves ordinary
+characters.</li>
+<li><tt>^</tt> is an ordinary character except at the beginning of the
+RE or the beginning of a parenthesized subexpression.  Similarly,
+<tt>$</tt> is an ordinary character except at the end of the
+RE or the end of a parenthesized subexpression.</li>
+</ul>

+This code is structured roughly as follows:
+
+xmalloc.c:
+  - Wrappers for the malloc() functions, for error generation and
+    memory leak checking purposes.
+
+tre-mem.c:
+  - A simple and efficient memory allocator.
+
+tre-stack.c:
+  - Implements a simple stack data structure.
+
+tre-ast.c:
+  - Abstract syntax tree (AST) definitions.
+
+tre-parse.c:
+  - Regexp parser.  Parses a POSIX regexp (with TRE extensions) into
+    an abstract syntax tree (AST).
+
+tre-compile.c:
+  - Compiles ASTs to ready-to-use regex objects.  Comprised of two parts:
+    * Routine to convert an AST to a tagged AST.  A tagged AST has
+      appropriate minimized or maximized tags added to keep track of
+      submatches.
+    * Routine to convert tagged ASTs to tagged nondeterministic state
+      machines (TNFAs) without epsilon transitions (transitions on
+      empty strings).
+
+tre-match-parallel.c:
+  - Parallel TNFA matcher.
+    * The matcher basically takes a string and a TNFA and finds the
+      leftmost longest match and submatches in one pass over the input
+      string.  Only the beginning of the input string is scanned until
+      a leftmost match and longest match is found.
+    * The matcher cannot handle back references, but the worst case
+      time consumption is O(l) where l is the length of the input
+      string.  The space consumption is constant.
+
+tre-match-backtrack.c:
+  - A traditional backtracking matcher.
+    * Like the parallel matcher, takes a string and a TNFA and finds
+      the leftmost longest match and submatches.  Portions of the
+      input string may (and usually are) scanned multiple times.
+    * Can handle back references.  The worst case time consumption,
+      however, is O(k^l) where k is some constant and l is the length
+      of the input string.  The worst case space consumption is O(l).
+
+tre-match-approx.c:
+  - Approximate parallel TNFA matcher.
+    * Finds the leftmost and longest match and submatches in one pass
+      over the input string.  The match may contain errors.  Each
+      missing, substituted, or extra character in the match increases
+      the cost of the match.  A maximum cost for the returned match
+      can be given.  The cost of the found match is returned.
+    * Cannot handle back references.  The space and time consumption
+      bounds are the same as for the parallel exact matcher, but
+      in general this matcher is slower than the exact matcher.
+
+regcomp.c:
+  - Implementation of the regcomp() family of functions as simple
+    wrappers for tre_compile().
+
+regexec.c:
+  - Implementation of the regexec() family of functions.
+    * The appropriate matcher is dispatched according to the
+      features used in the compiled regex object.
+
+regerror.c:
+  - Implements the regerror() function.

+  This matcher is for regexps that use back referencing.  Regexp matching
+  with back referencing is an NP-complete problem on the number of back
+  references.  The easiest way to match them is to use a backtracking
+  routine which basically goes through all possible paths in the TNFA
+  and chooses the one which results in the best (leftmost and longest)
+  match.  This can be spectacularly expensive and may run out of stack
+  space, but there really is no better known generic algorithm.	 Quoting
+  Henry Spencer from comp.compilers:
+  <URL: http://compilers.iecc.com/comparch/article/93-03-102>
+
+    POSIX.2 REs require longest match, which is really exciting to
+    implement since the obsolete ("basic") variant also includes
+    \<digit>.  I haven't found a better way of tackling this than doing
+    a preliminary match using a DFA (or simulation) on a modified RE
+    that just replicates subREs for \<digit>, and then doing a
+    backtracking match to determine whether the subRE matches were
+    right.  This can be rather slow, but I console myself with the
+    thought that people who use \<digit> deserve very slow execution.
+    (Pun unintentional but very appropriate.)

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl    default (if it is not specified or empty) is 'no-libtool'.
+dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+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). If INTLSYMBOL is 'no-libtool', a static library
+dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function
+dnl    will be ignored.  If NEEDSYMBOL is specified and is
+dnl    'need-formatstring-macros', then GNU gettext implementations that don't
+dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries.  If empty,
+dnl    the value `$(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.
