;;; Commentary:
;; This file contain editing mode functions and font-lock support for
;; editing Sieve scripts. It sets up C-mode with support for
;; sieve-style #-comments and a lightly hacked syntax table. It was
;; strongly influenced by awk-mode.el.
;;
;; Put something similar to the following in your .emacs to use this file:
;;
;; (load "~/lisp/sieve")
;; (setq auto-mode-alist (cons '("\\.siv\\'" . sieve-mode) auto-mode-alist))
;;
;; References:
;;
;; RFC 3028,
;; "Sieve: A Mail Filtering Language",
;; by Tim Showalter.
;;
;; Release history:
;;
;; 2001-03-02 version 1.0 posted to gnu.emacs.sources
;; version 1.1 change file extension into ".siv" (official one)
;; added keymap and menubar to hook into sieve-manage
;; 2001-10-31 version 1.2 committed to Oort Gnus
