5# SYNOPSIS
6#
7#   AX_PYTHON
8#
9# DESCRIPTION
10#
11#   This macro does a complete Python development environment check.
12#
13#   It recurses through several python versions (from 2.1 to 2.6 in this
14#   version), looking for an executable. When it finds an executable, it
15#   looks to find the header files and library.
16#
17#   It sets PYTHON_BIN to the name of the python executable,
18#   PYTHON_INCLUDE_DIR to the directory holding the header files, and
19#   PYTHON_LIB to the name of the Python library.
20#
21#   This macro calls AC_SUBST on PYTHON_BIN (via AC_CHECK_PROG),
22#   PYTHON_INCLUDE_DIR and PYTHON_LIB.
