;;; Commentary:
;;; Code:
;; This is a good place to gather code that is used for compatibility
;; between different versions of Emacs. Please document which versions
;; of Emacs that the defsubst, defalias, or defmacro applies. That
;; way, it's easy to occasionally go through this file and see which
;; macros we can retire.
;; Please use mh-gnus.el when providing compatibility with different
;; versions of Gnus.
;; Items are listed alphabetically.
