+
+ ;; Souped up by address@hidden based on ideas of address@hidden
+ ;; New features include attribute and keyword support, message

+ ;; 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.
