Peter something else that needs to be mentioned is that the backend
you've mentioned here, and of course is (partially) documented on the
Wiki, is that according to Google Code, it is in archive only status.
That means that everything there is in its final status. Nothing new
will be committed, unless someone on our list had the foresight to
export it to Github prior to that event.
