+MENU BEGIN [tagname]
+MENU END
+
+	Begin/end a submenu.  The entries between MENU BEGIN and MENU
+	END form a submenu, which is marked with a > mark on the right
+	hand of the screen.  Submenus inherit the properties of their
+	parent menus, but can override them, and can thus have their
+	own backgrounds, master passwords, titles, timeouts, messages
+	and so forth.

+MENU GOTO tagname

+
+	This label will transfer to the named submenu instead of

+	WARNING: if MENU MASTER PASSWD or ALLOWOPTIONS 0 is set, this
+	will still allow exiting to the CLI; however, a separate MENU
+	PASSWD can of course be set for this label.
