[Buildbot-devel] VCS polling question

[Amber Yust]

http://buildbot.net/buildbot/docs/0.8.2/Change-Filters.html#Change-Filters

<http://buildbot.net/buildbot/docs/0.8.2/Change-Filters.html#Change-Filters>(Also
a clarification, you create a ChangeFilter object, and then pass that object
to the change_filter parameter of the scheduler.)
