I've been trying to contact the maintainer of pysvn for a few weeks
(Since December 14th) but have not received a reply. According to Koji,
the owner (ravenoak) has not been active since July. I'd like to
formally request being added as a comaintainer of this package, as it is
a broken dependency in EPEL 6 for one of the packages I maintain
(ReviewBoard).

I am also willing to assume comaintainership in Fedora.
