;; Souped up by shane@mit-ajax based on ideas of rlk@athena.mit.edu
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: pmail and pmail-summary buffers remain
36
;; synchronized and key bindings basically operate the same way in both
37
;; buffers, summary by topic or by regular expression, pmail-reply-prefix
38
;; variable, and a bury pmail buffer (wipe) command.
