Cool.  Sorry for taking so long to respond here. :)

Yup, agreed.  As I mentioned in a previous email, it'll be a one-way
mirror, but that's better than having nothing on GitHub.

We might as well migrate everything, since some day the Bazaar server
will go away, even if that turns out to be a couple years from now.

As far as I know, it is still up but read-only.

Yeah, for sure, assuming CVS is up to date with Bazaar there should be
no problem here.  I don't seem to have access to the CVS server right
