#
# SYNOPSIS
#
# AX_PROG_PYTHON_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
#
# DESCRIPTION
#
# Makes sure that python supports the version indicated. If true the shell
# commands in ACTION-IF-TRUE are executed. If not the shell commands in
# ACTION-IF-FALSE are run. Note if $PYTHON is not set (for example by
# running AC_CHECK_PROG or AC_PATH_PROG) the macro will fail.
#
# Example:
#
# AC_PATH_PROG([PYTHON],[python])
# AX_PROG_PYTHON_VERSION([2.4.4],[ ... ],[ ... ])
#
# This will check to make sure that the python you have supports at least
# version 2.4.4.
#
# NOTE: This macro uses the $PYTHON variable to perform the check.
# AX_WITH_PYTHON can be used to set that variable prior to running this
# macro. The $PYTHON_VERSION variable will be valorized with the detected
# version.
