+ ;;; Commentary:
+ 
+ ;; 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.
