-FREETYPE LICENSES
------------------
-
-The FreeType  2 font  engine is  copyrighted work  and cannot  be used
-legally without  a software  license.  In order  to make  this project
-usable to  a vast majority of  developers, we distribute it  under two
-mutually exclusive open-source licenses.
-
-This means that *you* must choose  *one* of the two licenses described
-below, then obey all its terms and conditions when using FreeType 2 in
-any of your projects or products.
-
-  - The FreeType License,  found in the file  `docs/FTL.TXT`, which is
-    similar to the  original BSD license *with*  an advertising clause
-    that forces  you to explicitly  cite the FreeType project  in your
-    product's  documentation.  All  details are  in the  license file.
-    This license is suited to products which don't use the GNU General
-    Public License.
-
-    Note that  this license  is compatible to  the GNU  General Public
-    License version 3, but not version 2.
-
-  - The   GNU   General   Public   License   version   2,   found   in
-    `docs/GPLv2.TXT`  (any  later  version  can  be  used  also),  for
-    programs  which  already  use  the  GPL.  Note  that  the  FTL  is
-    incompatible with GPLv2 due to its advertisement clause.
-
-The contributed  BDF and PCF  drivers come  with a license  similar to
-that  of the  X Window  System.   It is  compatible to  the above  two
-licenses (see files `src/bdf/README`  and `src/pcf/README`).  The same
-holds   for   the   source    code   files   `src/base/fthash.c`   and
-`include/freetype/internal/fthash.h`; they wer part  of the BDF driver
-in earlier FreeType versions.
-
-The gzip  module uses the  zlib license (see  `src/gzip/zlib.h`) which
-too is compatible to the above two licenses.
-
-The  MD5 checksum  support  (only used  for  debugging in  development
-builds) is in the public domain.

-# 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.
