+;;; Commentary:
+
+;;; Code:
+
+;; Souped up by address@hidden based on ideas of address@hidden
+;; 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.
