IdleX is a collection of over twenty extensions and plugins that
provide additional functionality to IDLE, a Python IDE provided in
the standard library. It transforms IDLE into a more useful tool for
academic research and development as well as exploratory programming.
IdleX runs with Python 2.6, 2.7, and 3.x.

If you want to build this for use with Python 3.x (needs the optional
dependency python3) pass the script PYTHON3=yes, like:

PYTHON3=yes ./idlex.SlackBuild
