1.1 root 1: ; This file implements a "mail draft mode" for composition of messages in
2: ; the MH mail handler (q.v.). When MH calls Emacs, its customary call
3: ; is
4: ; emacs ./reply ./message -lmh-mode -email-draft-mode
5: ; for the case of a reply, and
6: ; emacs ./draft -lmh-mode -email-draft-mode
7: ; for a newly originated message.
8: ;
9: ; For use from mhe, in which Emacs calls MH instead of vice versa, it will
10: ; work fine as long as the function mail-draft-mode is not called.
