+#  builddir (required): which subdirectory to run the builder in
+#  factory (required): a BuildFactory to define how the build is run
+#  periodicBuildTime (optional): if set, force a build every N seconds
+
+# buildbot/process/factory.py provides several BuildFactory classes you can
+# start with, which implement build processes for common targets (GNU
+# autoconf projects, CPAN perl modules, etc). The factory.BuildFactory is the
+# base class, and is configured with a series of BuildSteps. When the build
+# is run, the appropriate buildslave is told to execute each Step in turn.
+
+# the first BuildStep is typically responsible for obtaining a copy of the
+# sources. There are source-obtaining Steps in buildbot/steps/source.py for
+# CVS, SVN, and others.
