      Ok, I'll have to read it more attentively when I come round to trying it,
      thanks for the info!

      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
      Jon said, that Tzachi is about to present his patches, so, we decided to
      wait. Would be really nice to use git instead of svn - for easier
      interoperability with mainline developers and for all the advantages of
