I've managed to get the progress I made on my window manager into CVS. I did a lot of work on it whilst at my grand parents a few weeks ago, but I didn't have net access. What I did was stick my checked-out copy of the CVS into a new RCS repository.
I have now finished getting each successive revision out of the RCS repository and sticking them into the CVS. I ended up doing this by hand, but I did look at some tools which may come in handy in the future - not least the perl module Rcs.
If you are interested in seeing a fairly useless window manager, head on over to /code/wm. If you can think of a good name for it, please let me know!
