a Semi-working CLISP with ILISP in Emacs

["Ziad H. Najem" <najem@cs.uiuc.edu>]

Hi, 

I Have hacked an ilisp-mode to get clisp working with ilisp. 
I'm not very familier with emacs-lisp so the following is actually
done by looking at other code and trial-and-error. But it works for
the most part. 

The ilisp package resides in /usr/emacs/ilisp
The clisp package resides in /usr/local/lib/lisp

The necessery code is spread into two files. One part is in
$HOME/.emacs and the other is in /usr/local/lib/lisp/emacs.el. I can
start lisp from emacs by executing the 'zlisp' extended command (M-X
zlisp) or by issuing the following script from shell

#!/bin/bash
exec emacs -l /usr/local/lib/lisp/emacs.el -f zlisp

Finally, attached is what appears in my $HOME/.emacs and
/usr/local/lib/ilisp/emacs.el. Please report any problems to me and I
would be interested in seeing any enhancements. 

Hope that helps,
