I've worked with only one such system: CLOS (which may or may not also be
referred to as PCL--Portable Common Loops).  I believe it is public domain
written by some folks at some Texas institution of higher learning.
I don't know where to get documentation about this package, though I do
have a copy of some documentation describing concepts and mechanisms.
If you would like a copy, let me know and I can send it via US mail.

I liked it alot, I thought it did everything I wanted it to do in terms of
inheritance, defining subclasses as combinations of multiple parent classes,
etc.  There were a couple of bugs we had to get around, and it didn't seem
to be incredibly fast, but what do you expect from Lisp (and I was even on
a TI Explorer Lisp machine!).  Overall, I recommend it.
