title: Setting SLIME in emacs
body: <p>I was trying to install SLIME. I downloaded the zipped package and according to the README file, I have to put this piece of code in my Emacs configuration file:</p>
  
  <pre><code>(add-to-list 'load-path "~/hacking/lisp/slime/")  ; your SLIME directory
  (setq inferior-lisp-program "/opt/sbcl/bin/sbcl") ; your Lisp system
  (require 'slime)
  (slime-setup)
  </code></pre>
  
  <p>Setting the SLIME directory is straightforward, but what about the Lisp "system"? How do I find it?</p>
