Well, you need to know a little Perl :-)

You can open pipes to programs like gzip, tar, and unzip to do the
uncompression.  You'll probably have to create temp files in some
cases.  I'm unsure if there exists any Perl modules for interfacing to
gzip, tar, and zip files which would make things easier (note, I
believe there is a module for zip files, but it may only work under
Win32).

Note, you may have to commission someone to do the work if you are
unable to do so.  It appears that noone has developed any filter to do
auto-decompression.  Any decent Perl programmer should be able to
implement the functionality.  The mhexternal.pl file can serve
as basis for creating the filter for MHonArc.
