;;; Commentary:
;;
;; This file adds customize support for built-in variables.

;; While dumping Emacs, this file is loaded, but it only records
;; the standard values; it does not do the rest of the job.
;; Later on, if the user makes a customization buffer,
;; this file is loaded again with (require 'cus-start);
;; then it does the whole job.
