[Python-Dev] relative package imports, version numbering, yadda yadda

My bad.  I despise putting RCS identifiers in code I release, but I
don't always freeze them before incorporating other people's code in
my CVS tree.  I will fix this if I can and I promise to try not to
repeat this mistake in the future.
