+;;; Code:
+
+;; Souped up by shane@mit-ajax based on ideas of rlk@athena.mit.edu
+;;   New features include attribute and keyword support, message
+;;   selection by dispatch table, summary by attributes and keywords,
+;;   expunging by dispatch table, sticky options for file commands.
+
+;; Extended by Bob Weiner of Motorola
+;;   New features include: rmail and rmail-summary buffers remain
+;;   synchronized and key bindings basically operate the same way in both
+;;   buffers, summary by topic or by regular expression, rmail-reply-prefix
+;;   variable, and a bury rmail buffer (wipe) command.
