JSD API usage?

Can anybody point me to a really good example or tutorial that uses the
spidermonkey debugging api's?
(please don't point me to that 3rd party app jsdb.exe. No offense to the
authors, but thats not much of an example)

I'm looking for somebody who can give me an outline of what the api's do and
which ones I really need. I'm having a tough time finding good examples or
any documentation on this...

Thanks!

FYI:  We are embedding Spidermonkey into a multi-threaded C++ application
and writing a browser only debugger IDE for it.  The C++ app has a tiny http
server inside for reponding to the IDE...
