Without trying, it appears that Zope's tar.py already handles
compressed files.

Let names contain a list of all files to add, I'd say the following
might work:

archive = tar.tgzarchive("foo")
for n in names:
  data = open(n).read()
  archive.add(n, data)
archive.finish()
open("foo.tgz").write(archive)

It appears as if this would keep the compressed file in memory,
though; there is apparently no streaming tar library.
