7# A Utility Eclass that should be inherited by anything that deals with 10# @BLURB: A Utility Eclass that should be inherited by anything that deals with Python or Python modules.
8# Python or Python modules. 11# @DESCRIPTION:
9# 12# Some useful functions for dealing with Python.
10# - Features:
11# python_version() - sets PYVER/PYVER_MAJOR/PYVER_MINOR
12# python_tkinter_exists() - Checks for tkinter support in python
13# python_mod_exists() - Checks if a python module exists
14# python_mod_compile() - Compiles a .py file to a .pyc/.pyo
15# python_mod_optimize() - Generates .pyc/.pyo precompiled scripts
16# python_mod_cleanup() - Goes through /usr/lib*/python* to remove
17# orphaned *.pyc *.pyo
18# python_makesym() - Makes /usr/bin/python symlinks
