Well, there can always be more examples, but "generators" are
inherently an advanced concept: if you are writing a generator, then
you already should be pro enough to be able to consult the sources of
the various generators shipped with systemd.

i.e. it's not a beginners topic, it's a very low-level, technicallly
advanced one.
