 regarding the example for the !ForceScheduler in
 https://github.com/buildbot/buildbot/blob/master/master/docs/manual/cfg-
 schedulers.rst

 ---

 This example is not working with v0.9 anymore as branch, revision, etc
 parameters are removed. I'm trying to figure out what is the correct way
 of customizing Force Scheduler form in Buildbot 0.9 and how to specify
 branch to be built.

 If someone could provide a hint for the correct syntax, I'd be happy to
 contribute the update to documentation. Thanks!
