There was a mailing list for the unix re-implementation of rc by Byron Rakitzis, this includes many examples and general info.
Be careful however, there are a few significant syntatic
differenctes between Byron's RC and Plan9's one, I am fairly
sure these are detailed in an appendix at the end of Byron's
paper (in the source package).
info here.
