Here's how to get slime working with OpenMCL. I assume you have openmcl 
working so that merely typing openmcl in the terminal will run 
ccl/scripts/openmcl. If not, add the appropriate setenv (tcsh) or 
export (bash) so that your path includes ccl/scripts.

1. Download slime, and note it's location in your file system hierarchy.
2. Create a .emacs file in your home directory that reads as follows 
(obviously replace the paths with those on your system) or add the 
following to your existing .emacs:

(add-to-list 'load-path "/path/to/directory/of/slime")
		;; replace this ^ path with real path to slime folder
     (require 'slime)
     (add-hook 'lisp-mode-hook (lambda () (slime-mode t)))
     (add-hook 'inferior-lisp-mode-hook (lambda () (inferior-slime-mode 
t)))
     (setq inferior-lisp-program  "/path/to/ccl/scripts/openmcl")
		;; replace this ^ path with real path to ccl/scripts/openmcl
     (setq font-lock-mode t)
     (setq common-lisp-hyperspec-root 
"file:///path/to/your/HyperSpec-6-0/HyperSpec/")
			;; replace this ^ path with real path to your local Hyperspec folder

3. In Terminal.app, type:
emacs
4. In emacs type:
M-x slime (i.e., meta-x slime )
5. If you want to be able to use the option key as the meta key in 
emacs (instead of the escape key - yuck!) go to Terminal:Window 
Settings and select the Keyboard pop-up, then check the box that reads: 
Use option key as meta key. If you want this to be the default for all 
Terminal windows, then click the button Use Setting as Defaults.

I assume you know how to use emacs' multiple windows, switching buffers 
etc. If you haven't used slime before, be aware that the *slime-repl* 
buffer is not the same as your *inferior-lisp* buffer.

Some really basic starter help for slime:
M-x slime  - start slime
M-x font-lock-mode  - toggle font lock mode
C-h m   - show help for slime mode
C-x C-f  - open a file
C-c C-k - compile and load the current buffer
C-x C-b - list all buffers
C-x b - switch to named buffer
Tab - completion
C-c C-h - look up symbol at point in Hyperspec


Happy hacking,

Raf
