I can't remember the exact issue, but I've had troubles in manually
creating a zip for use by Python (a zip that was going to be
imported).  I was investigating a bug, and for whatever reason, didn't
have the original source with me.  So I unzipped it, made the change,
and re-zipped it.  Python didn't like that.  So I did essentially the
same thing through zipfile in Python (only giving it the filenames of
things to be zipped--skipping directory entries), and it was fine.

That was the only time I ever ran into that sort of problem, but I
think it shows that if not done carefully, it could cause some issues.
