-;;; Commentary:
-
-;; This file has been obsolete since Emacs 22.1.
-
-;; This package provides equivalents of certain primitives from Gosling
-;; Emacs (including the commercial UniPress versions).  These have an
-;; ml- prefix to distinguish them from native GNU Emacs functions with
-;; similar names.  The package mlconvert.el translates Mocklisp code
-;; to use these names.
