590 \"Mail-Followup-To:\" header field if one
591 exists; otherwise forms a reply to the sender,
594 Depending on your answer, \"repl\" is given a different argument
595 to form your reply. Specifically, a choice of \"from\" or none at
596 all runs \"repl -nocc all\", and a choice of \"to\" runs \"repl
597 -cc to\". Finally, either \"cc\" or \"all\" runs \"repl -cc all
600 Two windows are then created. One window contains the message to
601 which you are replying in an MH-Show buffer. Your draft, in
602 MH-Letter mode (*note `mh-letter-mode'), is in the other window.
603 If the reply draft was not one that you expected, check the
604 things that affect the behavior of \"repl\" which include the
605 \"repl:\" profile component and the \"replcomps\" and
606 \"replgroupcomps\" files.
608 If you supply a prefix argument INCLUDEP, the message you are
609 replying to is inserted in your reply after having first been run
610 through \"mhl\" with the format file \"mhl.reply\".
612 Alternatively, you can customize the option `mh-yank-behavior'
613 and choose one of its \"Automatically\" variants to do the same
614 thing. If you do so, the prefix argument has no effect.
616 Another way to include the message automatically in your draft is
617 to use \"repl: -filter repl.filter\" in your MH profile.
619 If you wish to customize the header or other parts of the reply
620 draft, please see \"repl\" and \"mh-format\".
