12# - Features:
13# distutils_src_compile() - does python setup.py build
14# distutils_src_install() - does python setup.py install and install docs
15# distutils_python_version() - sets PYVER/PYVER_MAJOR/PYVER_MINOR
16# distutils_python_tkinter() - checks for tkinter support in python
17#
18# - Variables:
19# PYTHON_SLOT_VERSION - for Zope support
20# DOCS - additional DOCS
