40:  How do I change load-path?
  
  In general, you should only *add* to the load-path.  You can add
  directory /XXX/YYY to the load path like this:
  
    (setq load-path (append load-path '("/XXX/YYY/")))
  
  To do this relative to your home directory:
  
    (setq load-path (append load-path (list (expand-file-name "~/YYY/"))))
