;;; Commentary:
;; This utility allows you to automatically cut regions to a fortune
;; file. In case that the region stems from an article buffer (mail or
;; news), it will try to automatically determine the author of the
;; fortune. It will also allow you to compile your fortune-database
;; as well as providing a function to extract a fortune for use as your
;; signature.
;; Of course, it can simply display a fortune, too.
;; Use prefix arguments to specify different fortune databases.
;;; Installation:
;; Please check the customize settings -- you will at least have to
;; modify the values of `fortune-dir' and `fortune-file'.
;; I then use this in my .gnus:
;;(message "Making new signature: %s" (fortune-to-signature "~/fortunes/"))
;; This automagically creates a new signature when starting up Gnus.
;; Note that the call to fortune-to-signature specifies a directory in which
;; several fortune-files and their databases are stored.
;; If you like to get a new signature for every message, you can also hook
;; it into message-mode:
;; (add-hook 'message-setup-hook 'fortune-to-signature)
;; This time no fortune-file is specified, so fortune-to-signature would use
;; the default-file as specified by fortune-file.
;; I have also this in my .gnus:
;;(add-hook 'gnus-article-mode-hook
;; (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 favorite fortune-file.
