25 ;;; Commentary:
27 ;; This file adds customize support for built-in variables.
29 ;; While dumping Emacs, this file is loaded, but it only records
30 ;; the standard values; it does not do the rest of the job.
31 ;; Later on, if the user makes a customization buffer,
32 ;; this file is loaded again with (require 'cus-start);
33 ;; then it does the whole job.
