   1 ;;; ============ NOTE WELL! =============
   2 ;;;
   3 ;;; You only need to use this file if you're using a version of Emacs
   4 ;;; prior to 20.1 to work on GDB.  The only difference between this
   5 ;;; and the standard add-log.el provided with 19.34 is that it
   6 ;;; generates dates using the terser format used by Emacs 20.  This is
   7 ;;; the format recommended for use in GDB ChangeLogs.
   8 ;;;
   9 ;;; To use this code, you should create a directory `~/elisp', save the code
  10 ;;; below in `~/elisp/add-log.el', and then put something like this in
  11 ;;; your `~/.emacs' file, to tell Emacs where to find it:
  12 ;;;
  13 ;;; (setq load-path
  14 ;;;       (cons (expand-file-name "~/elisp")
  15 ;;;             load-path))
  16 ;;;
  17 ;;; If you want, you can also byte-compile it --- it'll run a little
  18 ;;; faster, and use a little less memory.  (Not that those matter much for
  19 ;;; this file.)  To do that, after you've saved the text as
  20 ;;; ~/elisp/add-log.el, bring it up in Emacs, and type
  21 ;;;
  22 ;;;     C-u M-x byte-compile-file
  23 ;;;
