| 25 | ;;; Commentary: | ||
| 26 | |||
| 27 | ;; The purpose of this library is to handle command line arguments | ||
| 28 | ;; when you resume an existing Emacs job. | ||
| 29 | |||
| 30 | ;; In order to use it, you must put this code in your .emacs file. | ||
| 31 | |||
| 32 | ;; (add-hook 'suspend-hook 'resume-suspend-hook) | ||
| 33 | ;; (add-hook 'suspend-resume-hook 'resume-process-args) | ||
| 34 | |||
| 35 | ;; You can't get the benefit of this library by using the `emacs' command, | ||
| 36 | ;; since that always starts a new Emacs job. Instead you must use a | ||
| 37 | ;; command called `edit' which knows how to resume an existing Emacs job | ||
| 38 | ;; if you have one, or start a new Emacs job if you don't have one. | ||
| 39 | |||
| 40 | ;; To define the `edit' command, run the script etc/emacs.csh (if you use CSH), | ||
| 41 | ;; or etc/emacs.bash if you use BASH. You would normally do this in your | ||
| 42 | ;; login script. | ||
| 43 | |||
| 44 | ;; Stephan Gildea suggested bug fix (gildea@bbn.com). | ||
| 45 | ;; Ideas from Michael DeCorte and other people. | ||
