You can find rezip clean/smudge filter (originally intended for
OpenDocument Format (ODF), that is OpenOffice.org etc.) that stores
zip or zip-archive (like ODT, jar, etc.) uncompressed.  I think
you can find it on GitWiki, but I might be mistaken.

There is also `textconv` filter that can be used instead; it might
be 'unzip -c' (extract files to stdout, with filenames), or 'unzip -p'
(same, without filenames).
