+;;; 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)
+;; (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.
