	Obviously I like the third option, as I proposed it :-)  But I
think Dave's really nailed how to split it out.  Originally, I expected
that his fence.git, fence-agents.git, cman.git, and rgmanager.git would
stay together as one tree, and that gfs and its utilities would also be
one tree.  Looking at it, though, I think he's right we split them out.
That's a result from our plan at the summit to start converging fence
agents and then eventually move fencing up the stack.  And I can tell
you from experience that separate kernel and tools trees for a
filesystem (ocfs2.git, ocfs2-tools.git) is a much nicer way to go.
