30 ;; New features include attribute and keyword support, message
31 ;; selection by dispatch table, summary by attributes and keywords,
32 ;; expunging by dispatch table, sticky options for file commands.
34 ;; Extended by Bob Weiner of Motorola
35 ;; New features include: rmail and rmail-summary buffers remain
36 ;; synchronized and key bindings basically operate the same way in both
37 ;; buffers, summary by topic or by regular expression, rmail-reply-prefix
38 ;; variable, and a bury rmail buffer (wipe) command.
