-;;; Commentary:
-
-;; These are extensions to Emacs Lisp that provide a degree of
-;; Common Lisp compatibility, beyond what is already built-in
-;; in Emacs Lisp.
-;;
-;; This package was written by Dave Gillespie; it is a complete
-;; rewrite of Cesar Quiroz's original cl.el package of December 1986.
-;;
-;; This package works with Emacs 18, Emacs 19, and Lucid Emacs 19.
-;;
-;; Bug reports, comments, and suggestions are welcome!
-
-;; This file contains emulations of internal routines of the older
-;; CL package which users may have called directly from their code.
-;; Use (require 'cl-compat) to get these routines.
-
-;; See cl.el for Change Log.
-
-
-;;; Code:
-
-;; This used to be:
-;; (or (featurep 'cl) (require 'cl))
-;; which just has the effect of fooling the byte-compiler into not
-;; loading cl when compiling.  However, that leads to some bogus
-;; compiler warnings.  Loading cl when compiling cannot do any harm,
-;; because for a long time bootstrap-emacs contained 'cl, due to being
-;; dumped from uncompiled files that eval-when-compile'd cl.  So every
-;; file was compiled with 'cl loaded.
-(require 'cl)

-
-;;; Multiple values.  Note that the new package uses a different
-;;; convention for multiple values.  The following definitions
-;;; emulate the old convention; all function names have been changed
-;;; by capitalizing the first letter: Values, Multiple-value-*,
-;;; to avoid conflict with the new-style definitions in cl-macs.
