+;;; HISTORY
+
+;; Still under construction: History obscure, needs a biographer as
+;; well as a M-x doctor. Change Log on request.
+
+;; Hacked by Olin Shivers for comint from Lars Bo Nielsen's sml.el.
+
+;; Hacked by Matthew Morley to incorporate Fritz Knabe's hilite and
+;; font-lock patterns, some of Steven Gilmore's (reduced) easy-menus,
+;; and numerous bugs and bug-fixes.
+
+;;; DESCRIPTION
+
+;; See accompanying info file: urweb-mode.info
+
+;;; FOR YOUR .EMACS FILE
+
+;; If urweb-mode.el lives in some non-standard directory, you must tell
+;; emacs where to get it. This may or may not be necessary:
+
+;; (add-to-list 'load-path "~jones/lib/emacs/")
+
+;; Then to access the commands autoload urweb-mode with that command:
+
+;; (load "urweb-mode-startup")
+
+;; urweb-mode-hook is run whenever a new urweb-mode buffer is created.
