-;;;
-;;; There used to be the following note here:
-;;; ;;; Note: defconst and defvar should NOT be marked in this way.
-;;; ;;; We don't want to produce defconsts and defvars that
-;;; ;;; make-docfile can grok, because then it would grok them twice,
-;;; ;;; once in foo.el (where they are given with ;;;###autoload) and
-;;; ;;; once in loaddefs.el.
-;;;
-;;; Counter-note: Yes, they should be marked in this way.
-;;; make-docfile only processes those files that are loaded into the
-;;; dumped Emacs, and those files should never have anything
-;;; autoloaded here. The above-feared problem only occurs with files
-;;; which have autoloaded entries *and* are processed by make-docfile;
-;;; there should be no such files.
