;;; Commentary:
;; All of the defgroups, defcustoms, and deffaces in MH-E are found
;; here. This makes it possible to customize modules that aren't loaded
;; yet. It also makes it easier to organize the customization groups.
;; This file contains the following sections:
;;
;; 1. MH-E Customization Groups
;;
;; These are the customization group definitions. Every group has a
;; associated manual node. The ordering is alphabetical, except for the
;; groups mh-faces and mh-hooks which are last .
;;
;; 2. MH-E Customization
;;
;; These are the actual customization variables. There is a sub-section for
;; each group in the MH-E Customization Groups section, in the same order,
;; separated by page breaks. Within each section, variables are sorted
;; alphabetically.
;;
;; 3. Hooks
;;
;; All hooks must be placed in the mh-hook group; in addition, add the
;; group associated with the manual node in which the hook is described.
;; Since the mh-hook group appears near the end of this file, the hooks
;; will appear at the end of these other groups.
;;
;; 4. Faces
;;
;; Create a new face group if necessary; in this case, add the group
;; associated with the manual node in which the faces are described to the
;; faces' group definition. Since the face groups appear last, the face
;; groups will appear at the end of these other groups.

sender's face will appear in the `From:' header field. If more than one of
these fields appear, then the first field found in the order `Face:',
`X-Face:', and `X-Image-URL:' will be used. Note that versions of GNU Emacs
prior to 21.1 don't support the display of inline images, so face images are
not displayed in these versions.
The option `mh-show-use-xface-flag' is used to turn this feature on and off.
This feature will be turned on by default if your system supports it.
The first header field used, if present, is the Gnus-specific `Face:' field.
The `Face:' field appeared in GNU Emacs 21 and XEmacs. For more information,
see http://quimby.gnus.org/circus/face/. Next is the traditional `X-Face:'
header field. The display of this field requires the `uncompface' program
which can be obtained from
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 which is
available at ftp://ftp.jpl.org/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' (available from
http://www.gnu.org/software/wget/wget.html), `fetch', or `curl' to fetch the
image and the `convert' program from the ImageMagick suite, available from
http://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.
The option `mh-fetch-x-image-url' controls the fetching of the `X-Image-URL:'
header field image."

"Define a tool bar for MH-E.
DEFAULTS is the list of buttons that are present by default. It is a list of
lists where the sublists are of the following form:
(:KEYWORD FUNC1 FUNC2 FUNC3 ...)
Here :KEYWORD is one of :folder or :letter. If it is :folder then the default
buttons in the folder and show mode buffers are being specified. If it is
:letter then the default buttons in the letter mode are listed. FUNC1, FUNC2,
FUNC3, ... are the names of the functions that the buttons would execute.
Each element of BUTTONS is a list consisting of four mandatory items and one
optional item as follows:
(FUNCTION MODES ICON DOC &optional ENABLE-EXPR)
where,
FUNCTION is the name of the function that will be executed when the button
is clicked.
MODES is a list of symbols. List elements must be from `folder', `letter' and
`sequence'. If `folder' is present then the button is available in the
folder and show buffer. If the name of FUNCTION is of the form \"mh-foo\",
where foo is some arbitrary string, then we check if the function
`mh-show-foo' exists. If it exists then that function is used in the show
buffer. Otherwise the original function `mh-foo' is used in the show buffer
as well. Presence of `sequence' is handled similar to the above. The only
difference is that the button is shown only when the folder is narrowed to a
sequence. If `letter' is present in MODES, then the button is available
during draft editing and runs FUNCTION when clicked.
ICON is the icon that is drawn in the button.
DOC is the documentation for the button. It is used in tool-tips and in
providing other help to the user. GNU Emacs uses only the first line of the
string. So the DOC should be formatted such that the first line is useful and
complete without the rest of the string.
Optional item ENABLE-EXPR is an arbitrary lisp expression. If it evaluates
to nil, then the button is deactivated, otherwise it is active. If is in't
present then the button is always active."

;; generation easier. Modifying the names should be done carefully.
