-# SYNOPSIS
-#
-# AX_PYTHON_DEFAULT
-# AX_PYTHON_ENABLE
-# AX_PYTHON_WITH
-# AX_PYTHON_PATH
-# AX_PYTHON_VERSION_ENSURE( [2.2] )
-# AX_PYTHON_CSPEC
-# AX_PYTHON_LSPEC
-#
-# DESCRIPTION
-#
-# This file provides autoconf support for those applications that want to
-# embed python. It supports all pythons >= 2.2 which is the first official
-# release containing distutils. Version 2.2 of python was released
-# December 21, 2001. Since it actually executes the python, cross platform
-# configuration will probably not work. Also, most of the platforms
-# supported are consistent until you look into Mac OS X. The python
-# included with it is installed as a framework which is a very different
-# environment to set up the normal tools such as gcc and libtool to deal
-# with. Therefore, once we establish which python that we are going to
-# use, we use its distutils to actually compile and link our modules or
-# applications.
-#
-# At this time, it does NOT support linking with Python statically. It
-# does support dynamic linking.
-#
-# This set of macros help define $PYTHON, $PYTHON_USE, $PYTHON_CSPEC and
-# $PYTHON_LSPEC. $PYTHON defines the full executable path for the Python
-# being linked to and is used within these macros to determine if that has
-# been specified or found. These macros do execute this python version so
-# it must be present on the system at configure time.
-#
-# $PYTHON_USE is an automake variable that defines whether Python support
-# should be included or not in your application. $PYTHON_CSPEC is a
-# variable that supplies additional CFLAGS for the compilation of the
-# application/shared library. $PYTHON_LSPEC is a variable that supplies
-# additional LDFLAGS for linking the application/shared library.
-#
-# The following is an example of how to set up for python usage within
-# your application in your configure.in:
-#
-# AX_PYTHON_DEFAULT( )
-# AX_PYTHON_ENABLE( ) # Optional
-# AX_PYTHON_WITH( ) # Optional
-# AX_PYTHON_PATH( ) # or AX_PYTHON_INSIST( )
-# # if $PYTHON is not defined, then the following do nothing.
-# AX_PYTHON_VERSION_ENSURE( [2.2] )
-# AX_PYTHON_CSPEC
-# AX_PYTHON_LSPEC
-#
-# The AX_PYTHON_DEFAULT sets the $PYTHON_USE to false. Thereby, excluding
-# it if it was optional.
-#
-# The AX_PYTHON_ENABLE looks for the optional configure parameters of
-# --enable-python/--disable-python and establishes the $PYTHON and
-# $PYTHON_USE variables accordingly.
-#
-# The AX_PYTHON_WITH looks for the optional configure parameters of
-# --with-python/--without-python and establishes the $PYTHON and
-# $PYTHON_USE variables accordingly.
-#
-# The AX_PYTHON_PATH looks for python assuming that none has been
-# previously found or defined and issues an error if it does not find it.
-# If it does find it, it establishes the $PYTHON and $PYTHON_USE variables
-# accordingly. AX_PYTHON_INSIST could be used here instead if you want to
-# insist that Python support be included using the --enable-python or
-# --with-python checks previously done.
-#
-# The AX_PYTHON_VERSION_ENSURE issues an error if the Python previously
-# found is not of version 2.2 or greater.
-#
-# Once that these macros have be run, we can use PYTHON_USE within the
-# makefile.am file to conditionally add the Python support such as:
-#
-# Makefile.am example showing optional inclusion of directories:
-#
-# if PYTHON_USE
-# plugins = plugins
-# src = src
-# else
-# plugins =
-# src =
-# endif
-#
-# SUBDIRS = . $(plugins) $(src)
-#
-# Makefile.am example showing optional shared library build:
-#
-# if PYTHON_USE
-# lib_LTLIBRARIES = libElemList.la
-# libElemList_la_SOURCES = libElemList.c
-# libElemList_la_CFLAGS = @PYTHON_CSPEC@
-# libElemList_la_LDFLAGS = @PYTHON_LSPEC@
-# endif
-#
-# Makefile.am example showing optional program build:
-#
-# if PYTHON_USE
-# bin_PROGRAMS = runFunc
-# runFunc_SOURCES = runFunc.c
-# runFunc_CFLAGS = @PYTHON_CSPEC@
-# runFunc_LDFLAGS = @PYTHON_LSPEC@
-# endif
-#
-# The above compiles the modules only if PYTHON_USE was specified as true.
-# Also, the else portion of the if was optional.
