Lisp code that uses features from the CL package should include at the beginning:
(require 'cl)
If you want to ensure that the new (Gillespie) version of CL
is the one that is present, add an additional (require 'cl-19)
call:
(require 'cl) (require 'cl-19)
The second call will fail (with "`cl-19.el' not found") if the old `cl.el' package was in use.
It is safe to arrange to load CL at all times, e.g.,
in your `.emacs' file. But it's a good idea, for portability,
to (require 'cl) in your code even if you do this.
