;;; Commentary:
;; Provides `tool-bar-mode' to control display of the tool-bar and
;; bindings for the global tool bar with convenience functions
;; `tool-bar-add-item' and `tool-bar-add-item-from-menu'.
;; The normal global binding for [tool-bar] (below) uses the value of
;; `tool-bar-map' as the actual keymap to define the tool bar. Modes
;; may either bind items under the [tool-bar] prefix key of the local
;; map to add to the global bar or may set `tool-bar-map'
;; buffer-locally to override it. (Some items are removed from the
;; global bar in modes which have `special' as their `mode-class'
;; property.)
;; Todo: Somehow make tool bars easily customizable by the naive?
;;; Code:
;; The autoload cookie doesn't work when preloading.
;; Deleting it means invoking this command won't work
;; when you are on a tty. I hope that won't cause too much trouble -- rms.
