I responded directly to Tw, but for the record I use
Jim Fulton's tar.py.  IIRC, it's not documented in the 
Zope distribution, but it's pretty easy to use.  Download
Zope from http://www.zope.org.

An example of building a test.tgz archive from files 
listed on the command line:

    if __name__ == '__main__':
        files = sys.argv[1:]
        archive = tgzarchive('test')
        for filename in files:
            f = open(filename, 'rb')
            archive.add(filename, f.read())
        archive.finish()
        outfile = open('test.tgz', 'wb')
        outfile.write(str(archive))
        outfile.close()
