handling tar, gz and bz2 with python

[Matthew Thorley]

Is there a module for unpacking tar files in python? how about bzip2 and
gzips? I know I can use the gzip module for gzips but is there anything
that can detect what format a file is in and decopress and unpack it
using the other methods?

thanks
