- ;;; 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.
