;;; mh-e.el --- GNU Emacs interface to the MH mail system
;; Copyright (C) 1985-1988, 1990, 1992-1995, 1997, 1999-2020 Free
;; Software Foundation, Inc.
;; Author: Bill Wohler <wohler@newt.com>
;; Version: 8.6+git
;; Keywords: mail
;; This file is part of GNU Emacs.

;;; Commentary:
;; MH-E is an Emacs interface to the MH mail system.
;; MH-E is supported in GNU Emacs 21 and higher, as well as XEmacs 21
;; (except for versions 21.5.9-21.5.16). It is compatible with MH
;; versions 6.8.4 and higher, all versions of nmh, and GNU mailutils
;; 1.0 and higher. Gnus is also required; version 5.10 or higher is
;; recommended.
;; MH (Message Handler) is a powerful mail reader. See
;; http://rand-mh.sourceforge.net/.
;; N.B. MH must have been compiled with the MHE compiler flag or several
;; features necessary for MH-E will be missing from MH commands, specifically
;; the -build switch to repl and forw.
;; How to use:
;; M-x mh-rmail to read mail. Type C-h m there for a list of commands.
;; C-u M-x mh-rmail to visit any folder.
;; M-x mh-smail to send mail. From within the mail reader, "s" works, too.
;; Your .emacs might benefit from these bindings:
;; (global-set-key "\C-cr" 'mh-rmail)
;; (global-set-key "\C-xm" 'mh-smail)
;; (global-set-key "\C-x4m" 'mh-smail-other-window)
;; If Emacs can't find mh-rmail or mh-smail, add the following to ~/.emacs:
;; (require 'mh-autoloads)
;; If you want to customize MH-E before explicitly loading it, add this:
;; (require 'mh-cus-load)
;; Mailing Lists:
;; mh-e-users@lists.sourceforge.net
;; mh-e-announce@lists.sourceforge.net
;; mh-e-devel@lists.sourceforge.net
;; Subscribe by sending a "subscribe" message to
;; <list>-request@lists.sourceforge.net, or by using the web interface at
;; https://sourceforge.net/mail/?group_id=13357
;; Bug Reports:
;; https://sourceforge.net/tracker/?group_id=13357&atid=113357
;; Include the output of M-x mh-version in the bug report unless
;; you're 110% sure we won't ask for it.
;; Feature Requests:
;; https://sourceforge.net/tracker/?group_id=13357&atid=363357
;; Support:
;; https://sourceforge.net/tracker/?group_id=13357&atid=213357
;;; Change Log:
;; Original version for Gosling emacs by Brian Reid, Stanford, 1982.
;; Modified by James Larus, BBN, July 1984 and UCB, 1984 & 1985.
;; Rewritten for GNU Emacs, James Larus, 1985.
;; Modified by Stephen Gildea, 1988.
;; Maintenance picked up by Bill Wohler and the
;; SourceForge Crew <http://mh-e.sourceforge.net/>, 2001.
;;; Code:
;; Provide functions to the rest of MH-E. However, mh-e.el must not
;; use any definitions in files that require mh-e from mh-loaddefs,
;; for if it does it will introduce a require loop.

set this option to \"Specify a scan Format File\" and enter the name

If you change the format of the scan lines you'll need to tell MH-E
how to parse the new format. As you will see, quite a lot of variables
are involved to do that. Use \"\\[apropos] RET mh-scan.*regexp\" to
obtain a list of these variables. You will also have to call
`mh-set-cmd-note' if your notations are not in column 4 (columns in
Emacs start with 0)."

header field. If more than one of these fields appear, then the first

The option `mh-show-use-xface-flag' is used to turn this feature on

\"Face:\" field. The \"Face:\" field appeared in GNU Emacs 21 and
XEmacs. For more information, see URL
`https://quimby.gnus.org/circus/face/'. Next is the traditional
\"X-Face:\" header field. The display of this field requires the
\"uncompface\" program (see URL
`ftp://ftp.cs.indiana.edu/pub/faces/compface/compface.tar.z'). Recent
versions of XEmacs have internal support for \"X-Face:\" images. If
your version of XEmacs does not, then you'll need both \"uncompface\"
and the x-face package (see URL `http://www.jpl.org/ftp/pub/elisp/').
Finally, MH-E will display images referenced by the \"X-Image-URL:\"
header field if neither the \"Face:\" nor the \"X-Face:\" fields are
present. The display of the images requires \"wget\" (see URL
`https://www.gnu.org/software/wget/wget.html'), \"fetch\", or \"curl\"
to fetch the image and the \"convert\" program from the ImageMagick
suite (see URL `https://www.imagemagick.org/'). Of the three header
fields this is the most efficient in terms of network usage since the
image doesn't need to be transmitted with every single mail.
