The Copycat system runs under Sun Common Lisp.  I have run it under version 
3.0.2 (which patches some bugs in version 3.0).  I don't know whether or not
it will run correctly under version 3.0.  

Copycat has a graphics interface, which runs under SunView.  The system
needs a Sun 3 or 4 with at least 8 MB of memory, and preferably with 12 MB
or more.  The less memory, the slower the program will run. 

This directory contains all the files you need to run Copycat.  
These files are the following:

Instruction files:
------------------
READ-ME-FIRST (this file)
how-to-set-up-copycat (instructions on how to set up the program 
                      using Sun Common Lisp and the files in this 
		      directory)
how-to-run-copycat (instructions on how to run the program)

Lisp initialization files (in the subdirectory "lisp-init"):
------------------------------------------------------------
lisp-init.lisp.windows (lisp initialization file for running Copycat under Sun
                       Common Lisp's window system)
lisp-init.lisp.no-windows (lisp initialization file for running Copycat with 
                          no windows or graphics)


Lisp utility files (in the subdirectory "ccat-src"):
----------------------------------------------------
lucid-util.l (some utility functions used by Copycat)
lucid-util.w (a writeup on the utility functions)
file-system-sun3.l or file-system-sun4.l 
     (routines for setting up a file system in Lisp)
file-system.w (a writeup on the file-system routines)
lucid-graphics.c (the C graphics routines used by Copycat)
lucid-graphics.w (a writeup on the graphics routines)
load-lucid-graphics-sun3.l or load-lucid-graphics-sun4.l  
     (routines for loading the C graphics routines into Lisp)


File for setting up Copycat system (in the subdirectory "ccat-src"):
--------------------------------------------------------------------
set-up-copycat-sun3.l or set-up-copycat-sun4.l
(compiles and loads the Lisp utility and Copycat-system files into Lisp)
