I forgot to explain: the .zip format (which is what the 'zipfile'
module produces and consumes) is an archive file format -- it stores
the data for multiple files in a single file.  What I'm looking to
do is interoperably read and write .zip format files using the
stronger 'bz2' compression within the .zip file for compression of
individual files within the archive, not for compression of the
entire archive as a single unit.
