-# AM_PATH_PYTHON_VERSION(ABI-VERSION1, [MINIMUM-VERSION1 [, ABI-VERSION2, [MINIMUM-VERSION2 ...]]])
-#
-# An alternative to AM_PATH_PYTHON that checks for specific python ABI/version pairs.
-# Example:
-# AM_PATH_PYTHON_VERSION(2.3, 2.3.5, 2.4, 2.4.0)
-# checks for a python2.3 binary returning python version >= 2.3.5, and
-# if that fails it looks for python2.4 containing version >= 2.4.0
-# It aborts configure with an error if no statisfying version is found.
-# Env. var. PYTHON can be used to point a specific/laternate version to configure.
