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 | ||
bd1f0f84 RS |
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. | |
