OPS5 comes with Allegro CL 4.3 (look in the contib directory).  There are
other inferencing engines around (Frolic and Screamer).

The Screamer reference is:

http://www.cis.upenn.edu/~screamer-tools/home.html

The Frolic reference is:

http://ftp.cs.utah.edu/pub/frolic.tar.Z

We also have a regular expression matching package, see 

ftp.franz.com/pub/regexp/

The documentation is in the file regexp.n in that directory.  We wrote it
as part of a sample Web server which is described in the April 1997 Tech
Notes (navigate through the "Technology" section of our Web site).

Hope this helps!

Jim.
