Each process registers itself, so you should be able to find that 
information from process_info(self()). Otherwise, nothing is passed 
explicitly to the callback.

I'm figuring this might be enough to get going.

It is, for all intents and purposes, a complete library. There has not 
been bug reports nor feature requests, so it is stable.

If someone were to report bugs, I would probably try and fix them, but 
it's been pretty calm and stable for the last 4 years. I haven't used or 
tried to use it (my work has moved to systems with different 
requirements) recently, but I'm still fine maintaining it.

If someone has a plan to improve the libs, I'd be fine handing control 
over, though.
