This will change with BitTorrent 5.0; the beta (4.9.6) currently uses
twisted-core and twisted-web.

This may already be out of date. I *think* Twisted Xish has been
incorporated into Twisted Words.

Can we have it yesterday please :-)

I had a go at making Extras-compatible versions of these (as you'll know
from bugzilla) and there are a few tweaks needed here and there, such as
doing proper directory ownership, ghosting of .pyo files, dependency
package name changes (e.g. SOAPpy instead of python-soappy), removal of
shellbangs from python files to shut rpmlint up etc.

Well the app has previously been approved but the packaging is now
sufficiently different that I think it would be worth re-reviewing.
Especially since most of the packages now have separate upstream
tarballs, get released at different times etc., and so are really
separate new packages.

There is a slight chicken-and-egg issue in that all of the packages
would need to be released together in order to provide a clean update
route from 1.3, but most of the packages have a build dependency on
python-twisted-core. So whoever was reviewing them all would have to
maintain a local repo if they were to test them using mock.

There's also an issue in that there's a new build dep for the main
package of python-zope-interface, so that will need to go in first.

Paul.
