I've opened an issue (#16) on github so I don't forget about the "Simple Example" request. No time right now, though.

And as far as resources are concerned, I had a little free time a few months ago that I used for reimplementing (parts of) the Rez compiler. It's buggy, has various missing features and it prefers crashing over reporting an error if it's given incorrect input, but it can compile .r files.
