[users at bb.net] Accessing properties within an extract_fn

[Pierre Tardy]

renderer looks good.
Maybe we need an extra step kind like manipulateProperties, which would
only take a renderer and run it, so that we dont need the extra shell
command on the worker.

BTW, I like you master.cfg a lot. nice work!

Would you like to make a blog post explaining it, like the nice folks at i3
did?

https://i3wm.org/docs/buildbot.html

We can host it in buildbot's Medium publication:

Pierre
