I have a semi-thick level binding to the CLIPS expert system shell on my
web site at
http://www.telepath.com/dennison/Ted/AdaClips/AdaClips.html

Its not a complete binding to CLIPS, but I did have to handle some
tricky stuff in there. So together with the CLIPS reference, it ought to
make for some good examples.

"Semi-thick" is my term for my own favorite style for bindings. A
"semi-thick" binding is one that abstracts away typical stupid C
artifacts like pointer interfaces, return error codes, and
null-termiated strings. That way the interface "feels" like Ada. But it
doesn't abstract things so much that the C docs for the routine can't be
used for the Ada bindings.

As to how "well-done" it is, I can't really give an impartial opinion.
But I've been writing Ada C bindings for over 11 years, so I at least
*ought* to know what I'm doing. :-)
