-;;; Commentary:
-
-;; This file has been obsolete since Emacs 21.1.
-
-;; This package can be used to arrange for automatic uncompress of
-;; compressed files when they are visited.
-;; All that's necessary is to load it.  This can conveniently be done from
-;; your .emacs file.
-
-;; M-x auto-compression-mode is a more modern replacement for this package.
-
-;;; Code:
-
-;; When we are about to make a backup file,
-;; uncompress the file we visited
-;; so that making the backup can work properly.
-;; This is used as a write-file-hook.
