# SYNOPSIS
#
#   AX_PYTHON_CONFIG_VAR(PYTHON_VARIABLE, [SHELL_VARIABLE])
#   AX_PYTHON_CONFIG_H
#   AX_PYTHON_MAKEFILE
#
# DESCRIPTION
#
#   AX_PYTHON_CONFIG_VAR:
#
#   Using the Python module distutils.sysconfig[1], return a Python
#   configuration variable. PYTHON_VARIABLE is the name of the variable to
#   request from Python, and SHELL_VARIABLE is the name of the shell
#   variable into which the results should be deposited. If SHELL_VARIABLE
#   is not specified, the macro wil prefix PY_ to the PYTHON_VARIABLE, e.g.,
#   LIBS -> PY_LIBS.
#
#   SHELL_VARIABLE is AC_SUBST'd. No action is taken if an error occurs.
#   Note if $PYTHON is not set, AC_CHECK_PROG(PYTHON, python, python) will
#   be run.
#
#   Example:
#
#     AX_PYTHON_CONFIG_VAR(LINKFORSHARED, PY_LFS)
#
#   AX_PYTHON_CONFIG_H:
#
#   Using the Python module distutils.sysconfig[1], put the full pathname of
#   the config.h file used to compile Python into the shell variable
#   PY_CONFIG_H. PY_CONFIG_H is AC_SUBST'd. Note if $PYTHON is not set,
#   AC_CHECK_PROG(PYTHON, python, python) will be run.
#
#   AX_PYTHON_MAKEFILE:
#
#   Using the Python module distutils.sysconfig[1], put the full pathname of
#   the Makefile file used to compile Python into the shell variable
#   PY_MAKEFILE. PY_MAKEFILE is AC_SUBST'd. Note if $PYTHON is not set,
#   AC_CHECK_PROG(PYTHON, python, python) will be run.
