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. -# -# LAST MODIFICATION -# -# 2007-08-04 -# -# COPYLEFT -# -# Copyright (c) 2007 Robert White <kranki@mac.com> -# Copyright (c) 2007 Dustin J.
