+
+ ;;; 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.
