;;; Commentary:
;; This package provides utility functions for intersections of gnus
;; and dired. To enable the gnus-dired-mode minor mode which will
;; have the effect of installing keybindings in dired-mode, place the
;; following in your ~/.gnus:
;; (require 'gnus-dired) ;, isn't needed due to autoload cookies
;; (add-hook 'dired-mode-hook 'turn-on-gnus-dired-mode)
;; Note that if you visit dired buffers before your ~/.gnus file has
;; been read, those dired buffers won't have the keybindings in
;; effect. To get around that problem, you may want to add the above
;; statements to your ~/.emacs instead.
