+;;; Commentary:
+
+;; This module provides integration of ERC into the Speedbar.
+
+;;; TODO / ideas:
+
+;; * Write intelligent update function:
+;;   update-channel, update-nick, remove-nick-from-channel, ...
+;; * Use indicator-strings for op/voice
+;; * Extract/convert face notes field from bbdb if available and show
+;;   it using sb-image.el
