Expert systems written in C...

[Michael J. Steiner]

I have been playing around with expert systems, and since I know (and
realize the superiority of :-)) C, I thought I would ask this question:

     Has anyone heard of any expert systems written in C, especially simple
     ones that could be understood without superhuman effort?

Any comments, pointers, or source code (|-O) would be welcome.
