+# SYNOPSIS
+#
+# AZ_PYTHON_DEFAULT
+# AZ_PYTHON_ENABLE
+# AZ_PYTHON_WITH
+# AZ_PYTHON_PATH
+# AZ_PYTHON_VERSION_ENSURE( [2.2] )
+# AZ_PYTHON_CSPEC
+# AZ_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
+# MacOSX. 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:
+#
+# AZ_PYTHON_DEFAULT( )
+# AZ_PYTHON_ENABLE( ) # Optional
+# AZ_PYTHON_WITH( ) # Optional
+# AZ_PYTHON_PATH( ) # or AZ_PYTHON_INSIST( )
+# # if $PYTHON is not defined, then the following do nothing.
+# AZ_PYTHON_VERSION_ENSURE( [2.2] )
+# AZ_PYTHON_CSPEC
+# AZ_PYTHON_LSPEC
+#
+# The AZ_PYTHON_DEFAULT sets the $PYTHON_USE to false. Thereby,
+# excluding it if it was optional.
+#
+# The AZ_PYTHON_ENABLE looks for the optional configure parameters of
+# --enable-python/--disable-python and establishes the $PYTHON and
+# $PYTHON_USE variables accordingly.
+#
+# The AZ_PYTHON_WITH looks for the optional configure parameters of
+# --with-python/--without-python and establishes the $PYTHON and
+# $PYTHON_USE variables accordingly.
+#
+# The AZ_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. AZ_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 AZ_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.
