#
# SYNOPSIS
#
# AC_PYTHON_DEVEL([version])
#
# DESCRIPTION
#
# Note: Defines as a precious variable "PYTHON_VERSION". Don't override it
# in your configure.ac.
#
# This macro checks for Python and tries to get the include path to
# 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS)
# output variables. It also exports $(PYTHON_EXTRA_LIBS) and
# $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code.
#
# You can search for some particular version of Python by passing a
# parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please
# note that you *have* to pass also an operator along with the version to
# match, and pay special attention to the single quotes surrounding the
# version number. Don't use "PYTHON_VERSION" for this: that environment
# variable is declared as precious and thus reserved for the end-user.
#
# This macro should work for all versions of Python >= 2.1.0. As an end
# user, you can disable the check for the python version by setting the
# PYTHON_NOVERSIONCHECK environment variable to something else than the
# empty string.
#
# If you need to use this macro for an older Python version, please
# contact the authors. We're always open for feedback.

# SYNOPSIS
#
# AZ_PYTHON_DEFAULT

# 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.
