Greetings. I'm currently leading a team building simulation/modeling
software for a network of our ATM switches. The current implementation
is Java and CLIPS; I would like to port the software to CLOS, with an
eye toward moving the CLIPS engine into some form of Lisp
implementation.

Does anyone know of a good Common Lisp package that implements OPS5 or
CLIPS? Our platform is Allegro CL 4.3 (Solaris and Linux). I'm aware
of Harlequin's KnowledgeWorks, but that product is apparently built
atop their LispWorks offering.

Along these lines, might there be a CL package that implements Perl5
regular expressions? Better yet, something that generates a Lisp-based
parser from a production rule grammar? Thanks very much.

Regards,
