dnl Checks for Python and tries to get the include path to 'Python.h'.
dnl It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS) output
dnl variables.
dnl Also exports $(PYTHON_EXTRA_LIBS) and $(PYTHON_EXTRA_LDFLAGS)
dnl for embedding Python in your code.
dnl
dnl You can search for some particular version of Python by passing a
dnl parameter to this macro, for example '>= 2.3.1', or '== 2.4'.
dnl Please note that you *have* to pass also an operator along
dnl with the version number.
dnl
dnl If the user wants to employ a particular version of Python, she can
dnl now pass to configure the PYTHON_VERSION environment variable.
dnl Should work for all versions of Python >= 2.1.0. You can disable the
dnl check for the python version by setting the PYTHON_NOVERSIONCHECK
dnl environment variable.
dnl This is only limited by the macro parameter set by the packager.
dnl
dnl This macro should work for all versions of Python >= 2.1.0. You can
dnl disable the check for the python version by setting the
dnl PYTHON_NOVERSIONCHECK environment variable.
dnl
dnl If you need to use this macro for an older Python version, please
dnl contact the authors. We're always open for feedback.
