[Buildbot-devel] Mercurial Forest and Buildbot?

[Marcus Lindblom]

I've read that one (seemingly) can kick off depedent schedulers, etc, 
wouldn't it be possible to create a 'super-scheduler' that arbitrated 
that stuff?

The 'build' that get's created would only have one change in it, but 
several builder would be started from one change.
