I'm working on an expert system running in CommonLISP and would like to port it
to the NeXT. I have some knowledge of Objective-C and the NeXT, but limited
knowledge of C. However, I would like most of the interface to be written in
C to speed up response time (previous system implemented on XEROX 1186 with
incredible slow interface). My problems are:

- where can I find proper information about the links from Objective-C to
  LISP and vice-versa (the sales reps on campus couldn't answer this, nor
  do I get an answer from NeXT, nor could an instructor at a NeXT seminar
  answer this question)

- I checked the manuals, but didn't find them helpful. I know how to write
  an Objective-C application in CommonLISP using the objc: packages and
  such, but not how to communicate between plain CommonLISP and my
  Objective-C interface

Any help would be greatly appreciated.
