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