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