+;;; Commentary:
+
+;; This package defines and redefines a bunch of functions for Gnus
+;; usage.  The basic (and somewhat unsound) idea is to make all
+;; Emacsen look like the current trunk of Emacs.  So it will define
+;; functions "missing" in other Emacs instances, and redefine other
+;; functions to work like the Emacs trunk versions.
