# SYNOPSIS
#
#   AX_PYTHON_DEVEL([version])
#
# DESCRIPTION
#

#   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_LIBS) 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

#   If you need to use this macro for an older Python version, please
#   contact the authors. We're always open for feedback.
