#!/usr/bin/env python
# A script for unpacking and installing different historic versions of
# Python in a consistent manner for side-by-side development testing.
# This was written for a Linux system (specifically Ubuntu) but should
# be reasonably generic to any POSIX-style system with a /usr/local
# hierarchy.
