27 | ;; Message composition of MIME message is done with either MH-style |
28 | ;; directives for mhn or mhbuild (MH 6.8 or later) or MML (MIME Meta | |
29 | ;; Language) tags. | |
30 | ||
31 | ;; TODO: | |
32 | ;; Paragraph code should not fill # lines if MIME enabled. | |
33 | ;; Implement mh-auto-mh-to-mime (if non-nil, \\[mh-send-letter] | |
34 | ;; invokes mh-mh-to-mime automatically before sending.) | |
35 | ;; Actually, instead of mh-auto-mh-to-mime, | |
36 | ;; should read automhnproc from profile. | |
37 | ;; MIME option to mh-forward command to move to content-description | |
38 | ;; insertion point. | |
