;;; Commentary:
;; This utility allows you to automatically cut regions to a fortune
;; I have also this in my .gnus:
;;(add-hook 'gnus-article-mode-hook
-;; '(lambda ()
+;; (lambda ()
;; (define-key gnus-article-mode-map "i" 'fortune-from-region)))
;; which allows marking a region and then pressing "i" so that the marked
;; region will be automatically added to my favourite fortune-file.
