;;; 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.
