Help finding CLIPS?

A friend writes:

I need some help in locating some public domain software.  
It's called CLIPS and is apparently put out by a company 
called COSMIC.  As I understand it, CLIPS is a C Language
Interpreter for LISP (as near as I can tell, it translates 
LISP to C).

If anyone can give pointers or has experience with this 
program, please respond by e-mail to 
barcio at cs.niu.edu  (Joe Barcio)

Thanks in advance.
