## Python file handling

dnl CHECK_PYTHON([module, classes])
dnl
dnl Adds support for distributing Python modules or classes.
dnl Python library files distributed as a `module' are installed
dnl under PYTHON_SITE_PACKAGE (eg, ./python1.5/site-package/package-name)
dnl while those distributed as `classes' are installed under PYTHON_SITE
dnl (eg, ./python1.5/site-packages).  The default is to install as
dnl a `module'.
