#!/usr/bin/env python
#
# A script for unpacking and installing different historic versions of
# SCons in a consistent manner for side-by-side development testing.
#
# This abstracts the changes we've made to the SCons setup.py scripts in
# different versions so that, no matter what version is specified, it ends
# up installing the necessary script(s) and library into version-specific
# names that won't interfere with other things.
#
# By default, we expect to extract the .tar.gz files from a Downloads
# subdirectory in the current directory.
#
# Note that this script cleans up after itself, removing the extracted
# directory in which we do the build.
#
# This was written for a Linux system (specifically Ubuntu) but should
# be reasonably generic to any POSIX-style system with a /usr/local
# hierarchy.
