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

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