28 ;;; Code:
29
30 ;; Souped up by shane@mit-ajax based on ideas of rlk@athena.mit.edu
31 ;; New features include attribute and keyword support, message
32 ;; selection by dispatch table, summary by attributes and keywords,
33 ;; expunging by dispatch table, sticky options for file commands.
34
35 ;; Extended by Bob Weiner of Motorola
36 ;; New features include: rmail and rmail-summary buffers remain
37 ;; synchronized and key bindings basically operate the same way in both
38 ;; buffers, summary by topic or by regular expression, rmail-reply-prefix
39 ;; variable, and a bury rmail buffer (wipe) command.
