Don't override it -# in your configure.ac. -# -# This macro checks for Python and tries to get the include path to -# 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS) -# output variables. It also exports $(PYTHON_EXTRA_LIBS) and -# $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code. -# -# You can search for some particular version of Python by passing a -# parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please -# note that you *have* to pass also an operator along with the version to -# match, and pay special attention to the single quotes surrounding the -# version number. Don't use "PYTHON_VERSION" for this: that environment -# variable is declared as precious and thus reserved for the end-user. -# -# This macro should work for all versions of Python >= 2.1.0. As an end -# user, you can disable the check for the python version by setting the -# PYTHON_NOVERSIONCHECK environment variable to something else than the -# empty string. -# -# If you need to use this macro for an older Python version, please -# contact the authors. We're always open for feedback. -# -# LAST MODIFICATION -# -# 2008-04-12 -# -# COPYLEFT -# -# Copyright (c) 2008 Sebastian Huber <sebastian-huber@web.de> -# Copyright (c) 2008 Alan W.
