 Replying to [comment:1 dustin]:
 > Are these parameters in the codebase now?

 As far as I understand the docs and code, yes, branches are now specified
 as part of `codebases` parameter. However I couldn't figure out how to use
 it properly.

 Overall I want to figure out 2 things with Buildbot 0.9:

 1. How to specify branches to ForceScheduler via `codebases`?
 2. How to create web form to ask user for specific branch in the web UI?

 Thanks!
