Could you explain that a bit more. Sounds like you saying it's worth
messing with the flamebox scripts to use git instead of using the git
cvserver and letting them pull the cvs branches as they do now. Is the
existing flamebox email of build log effected buy switching form cvs
to git? I hadn't expect it to change.

I get the impression your suggestion to first get git-cvsserver serving
the repo so that the build machines works without any change and then to
go to each build machine and update the scripts to use git instead of cvs.

Are there any tricks I need to so on the repo to make the branches pull
out with exactly the same commands that we are currently using. My guess
is that the branch checkouts should work without any messing around.

Hey, you two cents could easily save me hours of messing getting this
conversion done.

BTW, I don't think anyone is checking into the repo, but if they do
can I do another git-cvsimport to just update the one I already did?
