Which was the original plan, yes. The only hard part about this is moving
the passwords into ~/.subversion, because that directory currently doesn't
understand multiple repositories. I haven't had any time to work on this

upset, otherwise it is likely to take me a few weeks to finish. I get at
most an hour a night to code.
