;; (C) 2000 Free Software Foundation
;; Written by Martin v. Löwis
;; Usage:
;; In rmail, bind a key to rmail-gccbug-reply, e.g.
;;   (require 'rmail)
;;   (require 'gccbug)
;;   (define-key rmail-mode-map "R" 'rmail-gccbug-reply)
;; Then, when reviewing a report, type R to create a gnats-formatted
;; message.
