Just a request to you - you said you wanted to commit his patches and any
additional modifications you do into the sourceforge svn repository. We
talked with Jon a few weeks ago and agreed that it would be better to do
the *Pro development in a git tree. He's even set up a git server on the
linkstationwiki server, and we wanted to start committing there, but then

interoperability with mainline developers and for all the advantages of
