Disclaimer: I have only read the code and scanned the docs, not
actually tried this (yet).  But it looks to me as if you could also do
that in your master.cfg:

  c['properties'] = { 'foo': bar, 'baz': qux }

and then the 'source' of those properties will be set automatically.

Depends on how static your property values are, of course.  I have
properties for an external build ID and build label, so those will
have to set when I launch each build.  Luckily I have custom code for
that (reads a record from our build queue and turns it into a Buildbot
BuildRequest), so it looks fairly straightforward.  (Fingers crossed.)
