That's really zope.tar.gz; it's a gzip'ed tar file. Under UNIX we
consider collecting a bunch of files into one (tar) and compressing them
(compress or gzip) as two separate operations.
I don't know if there's tar functionality available for Python; if not,
simple concatenation of files with a tiny header at the end would be
relatively straightforward. There _is_, however, support for gzip in
Python; try the gzip module.
