;;; DESCRIPTION

;; You need auc-menu or easymenu on your lisp load-path.

;; Menus appear only when the cursor is in an sml-mode buffer. They
;; should appear automatically as long as sml-mode can find this file
;; and easymenu.el (or auc-menu.el), but not otherwise.

;; If you load sml-proc.el to run an inferior ML process -- or even a
;; superior one, who knows? -- the "Process" submenu will become active.

;;; CODE

(condition-case () (require 'easymenu) (error (require 'auc-menu)))

;; That's FSF easymenu, distributed with GNU Emacs 19, or Per
;; Abrahamsen's auc-menu distributed with AUCTeX, or from the Emacs
;; lisp archive, or the IESD (ftp://sunsite.auc.dk/packages/auctex/)
;; lisp archive at Aalborg (auc-menu works with XEmacs too).
