##### http://autoconf-archive.cryp.to/ax_python.html
#
# SYNOPSIS
#
# AX_PYTHON
#
# DESCRIPTION
#
# This macro does a complete Python development environment check.
#
# It recurses through several python versions (from 2.1 to 2.4 in
# this version), looking for an executable. When it finds an
# executable, it looks to find the header files and library.
#
# It sets PYTHON_BIN to the name of the python executable,
# PYTHON_INCLUDE_DIR to the directory holding the header files, and
# PYTHON_LIB to the name of the Python library.
#
# This macro calls AC_SUBST on PYTHON_BIN (via AC_CHECK_PROG),
# PYTHON_INCLUDE_DIR and PYTHON_LIB.
