You can use build properties in most step paramaters. Please file bugs for any
parameters which do not accept properties. The simplest form is to wrap the
property name with <code>Property</code>, passing an optional default argument.
<pre class="example"> from buildbot.steps.trigger import Trigger
form buildbot.process.properties import Property
f.addStep(Trigger(waitForFinish=False, schedulerNames=['build-dependents'], alwaysUseLatest=True,
set_properties={'coq_revision': Property("got_revision")}))
</pre>
<p>You can specify a default value by passing a <code>default</code> argument to
<code>Property</code>. This is normally used when the property doesn't exist,
or when the value is something Python regards as "false". The <code>defaultWhenFalse</code>
argument can be used to force buildbot to use the default argument only
if the parameter is not set.
