1 | ;;; ============ NOTE WELL! ============= |

| 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 | |
