27 | ;; This file contain editing mode functions and font-lock support for | |
28 | ;; editing Sieve scripts. It sets up C-mode with support for | |
29 | ;; sieve-style #-comments and a lightly hacked syntax table. It was | |
30 | ;; strongly influenced by awk-mode.el. | |
31 | ;; | |
32 | ;; Put something similar to the following in your .emacs to use this file: | |
33 | ;; | |
34 | ;; (load "~/lisp/sieve") | |
35 | ;; (setq auto-mode-alist (cons '("\\.siv\\'" . sieve-mode) auto-mode-alist)) | |
