27 ;; New features include attribute and keyword support, message
28 ;; selection by dispatch table, summary by attributes and keywords,
29 ;; expunging by dispatch table, sticky options for file commands.
31 ;; Extended by Bob Weiner of Motorola

33 ;; synchronized and key bindings basically operate the same way in both
34 ;; buffers, summary by topic or by regular expression, rmail-reply-prefix
35 ;; variable, and a bury rmail buffer (wipe) command.
