#
# SYNOPSIS
#
#   AX_PYTHON_DEVEL([version])
#
# DESCRIPTION
#
#   Note: Defines as a precious variable "PYTHON_VERSION". 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.
