# A script that takes an scons-src-{version}.zip file, unwraps it in
# a temporary location, and calls to execute one or more of
# its tests.
# The default is to download the latest scons-src archive from the SCons
# web site, and to execute all of the tests.
# With a little more work, this will become the basis of an automated
# testing and reporting system that anyone will be able to use to
# participate in testing SCons on their system and regularly reporting
# back the results.  A --xml option is a stab at gathering a lot of
# relevant information about the system, the Python version, etc.,
# so that problems on different platforms can be identified sooner.
