;; Keywords: file, tags, tools
;; This file is part of GNU Emacs.
;; AUC-TEX users: The imenu tags for AUC-TEX mode don't work very
;; well. Use the imenu keywords from tex-mode.el for better results.

+;; This file requires the library package assoc (association lists)

;;; Developing for speedbar
;;
;; Adding a speedbar specialized display mode:
;;; TODO:
;; - More functions to create buttons and options
;; - Timeout directories we haven't visited in a while.
-;; - Remeber tags when refreshing the display. (Refresh tags too?)
-;; - More 'special mode support.
