I have meanwhile submitted packages for both modglue and cadabra to
the Ubuntu REVU site for approval. They are not yet through though,
and sit in a dormant state (it's incredibly hard to find sponsorship
for scientific software, I have to say). But if you are interested in
pushing the packaging for Debian, it is probably best to start from
those Ubuntu packages.
See http://revu.ubuntuwire.com for more details.
Thanks, I was able to find cadabra there, but where do you have the
modglue debian source packages?
Let me know what you plan to do (I have more or less given up on ever
getting this into an official Debian repository).
If nobody wants to maintain it inside Debian I would, but perferably
I would like someone else to do it.
