-
-These chapters introduce another interface to MH that is accessible
-through the GNU Emacs editor, namely, @emph{mh-e}. mh-e is easy to use.
-I don't assume that you know GNU Emacs or even MH at this point, since I
-didn't know either of them when I discovered mh-e. However, mh-e was
-the tip of the iceberg, and I discovered more and more niceties about
-GNU Emacs and MH@. Now I'm fully hooked on both of them.
-
-@cindex history
-
-The mh-e package is distributed with GNU Emacs, @footnote{Note that
-mh-e is supported with MH 6 and @w{Emacs 18} and up.
-Reportedly, large parts of it work with @w{MH 5} and also with
-Lucid/XEmacs and Epoch, but there are no guarantees. It is also
-distributed with Lucid/XEmacs, as well as with MH itself.} so you
-shouldn't have to do anything special to use it. But it's important to
-note a brief history of mh-e. @w{Version 3} was prevalent through the
-@w{Emacs 18} and early @w{Emacs 19} years. Then @w{Version 4} came out
-(@w{Emacs 19.23}), which introduced several new and changed commands.
-Finally, @w{Version 5.0} was released, which fixed some bugs and
-incompatibilities, and was incorporated into @w{Emacs 19.29}. This is
-the version covered by this manual. @ref{Getting Started} will help
-you decide which version you have.
-
-If you don't already use GNU Emacs but want to learn more, you can read
-an online tutorial by starting GNU Emacs and typing @kbd{C-h t}
-(@code{help-with-tutorial}). (This notation is described in
-@ref{Conventions}.) If you want to take the plunge, consult the

+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.}, so you

+This manual is available in both Info and online formats. The Info
+version is distributed with Emacs and can be accessed with the
+@command{info} command (@samp{info mh-e}) or within Emacs (@kbd{C-h i
+m mh-e @key{RET}}). The online version is available at

-This chapter introduces some of the terms you'll need to know and then
-takes you on a tour of mh-e. @footnote{The keys mentioned in these
-chapters refer to the default key bindings. If you've changed the
-bindings, refer to the command summaries at the beginning of each major
-section in @ref{Using mh-e}, for a mapping between default key bindings
-and function names.} When you're done, you'll be able to send, read,
-and file mail, which is all that a lot of people ever do. But if you're
-the curious type, you'll read @ref{Using mh-e} to be able to use all
-the features of mh-e. If you're the adventurous type, you'll read
-@ref{Customizing mh-e} to make mh-e do what you want. I suggest you
-read this chapter first to get the big picture, and then you can read
-the other two as you wish.

+
+In general, @dfn{functions} in this text refer to Emacs Lisp functions
+that one would call from within Emacs Lisp programs (for example,
+@code{(mh-inc-folder)}). On the other hand, @dfn{commands} are those
+things that are run by the user, such as @kbd{i} or @kbd{M-x
+mh-inc-folder}. Programs outside of Emacs are specifically called MH
+commands, shell commands, or Unix commands.
+
+@cindex conventions, key names
+@cindex key names
+
+The conventions for key names are as follows:
@table @kbd
@item C-x
Hold down the @key{CTRL} (Control) key and press the @kbd{x} key.
+@c -------------------------
@item M-x
Hold down the @key{META} or @key{ALT} key and press the @kbd{x} key.
Since some keyboards don't have a @key{META} key, you can generate
-@kbd{M-x}, for example, by pressing @key{ESC} (Escape), @emph{releasing
-it}, @footnote{This is emphasized because pressing ESC twice or holding
-it down a second too long so that it repeats gives you an error message.}
-and then pressing the @kbd{x} key.
-@item RET
-Press the @key{RETURN} or @key{ENTER} key. This is normally used to
+@kbd{M-x}, for example, by pressing @key{ESC} (Escape),
+@emph{releasing it}, and then pressing the @kbd{x} key.
+@c -------------------------
+@item @key{RET}
+Press the @key{RETURN} or @key{ENTER} key. This is normally used to
complete a command.
-@item SPC
+@c -------------------------
+@item @key{SPC}
Press the space bar.
-@item TAB
+@c -------------------------
+@item @key{TAB}
Press the @key{TAB} key.
-@item DEL
+@c -------------------------
+@item @key{DEL}
Press the @key{DELETE} key.
-@item BS
-Press the @key{BACKSPACE} key. @footnote{If you are using Version 20
-or earlier of Emacs, you will need to use the @key{DEL} key.}
+@c -------------------------

@cindex Emacs, prefix argument
@cindex prefix argument
+@kindex C-u
A @dfn{prefix argument} allows you to pass an argument to any Emacs
-function. To pass an argument, type @kbd{C-u} before the Emacs command
-or keystroke. Numeric arguments can be passed as well. For example, to
-insert five f's, use @kbd{C-u 5 f}. There is a default of four when
+function. To pass an argument, type @kbd{C-u} before the Emacs command
+or keystroke. Numeric arguments can be passed as well. For example, to
+insert five f's, use @kbd{C-u 5 f}. There is a default of four when
using @kbd{C-u}, and you can use multiple prefix arguments to provide
-arguments of powers of four. To continue our example, you could insert
+arguments of powers of four. To continue our example, you could insert
four f's with @kbd{C-u f}, 16 f's with @kbd{C-u C-u f}, 64 f's with
-@kbd{C-u C-u C-u f}, and so on. Numeric and valueless negative
-arguments can also be inserted with the @key{META} key. Examples
+@kbd{C-u C-u C-u f}, and so on. Numeric and valueless negative
+arguments can also be inserted with the @key{META} key. Examples
include @kbd{M-5} to specify an argument of 5, or @kbd{M--} which
specifies a negative argument with no particular value.

The @dfn{minibuffer} is the bottom line of the Emacs window, where all
-prompting and multiple-character input is directed. If you are prompted
-for information in the minibuffer, such as a filename, Emacs can help
-you complete your answer if you type @key{SPC} or @key{TAB}. A second
-@key{SPC} or @key{TAB} will list all possibilities at that point. The
-minibuffer is also where you enter Emacs function names after typing
-@kbd{M-x}. For example, in the first paragraph, I mentioned that you
-could obtain help with @kbd{C-h t} (@code{help-with-tutorial}). What
+prompting and multiple-character input is directed. You can use
+@dfn{completion} to enter values such as folders. Completion means
+that Emacs fills in text for you when you type @key{SPC} or @key{TAB}.

+
+The minibuffer is also where you enter Emacs function names after
+typing @kbd{M-x}. For example, in the preface, I mentioned that you
+could obtain help with @kbd{C-h t} (@code{help-with-tutorial}). What
this means is that you can get a tutorial by typing either @kbd{C-h t}
-or @kbd{M-x help-with-tutorial}. In the latter case, you are prompted
-for @samp{help-with-tutorial} in the minibuffer after typing @kbd{M-x}.
+or @kbd{M-x help-with-tutorial}. In the latter case, you are prompted
+for @samp{help-with-tutorial} in the minibuffer after typing
+@kbd{M-x}.
+
+@cindex ~
+
+The @samp{~} notation in filenames represents your home directory.
+This notation is used by many shells including @command{bash},
+@code{tcsh}, and @command{csh}. It is analogous to the environment
+variable @samp{$HOME}. For example, @file{~/.emacs} can be written
+@file{$HOME/.emacs} or using the absolute path as in
+@file{/home/wohler/.emacs} instead.

-@key{RET}}. @footnote{You wouldn't ordinarily do this.} The message,
-@samp{Loading mh-e...done}, should be displayed in the minibuffer. If
-you get @samp{Cannot open load file: mh-e}, then your Emacs is very
-badly configured, or mh-e is missing. You may wish to have your system
-administrator install a new Emacs or at least the latest mh-e files.
-
-Having loaded mh-e successfully, enter @kbd{M-x mh-version @key{RET}}.
-The version of mh-e should be displayed. Hopefully it says that you're
-running @w{Version @value{VERSION}} which is the latest version as of
-this printing. If instead Emacs beeps and says @samp{[No match]}, then
-you're running an old version of mh-e.
-
-If these tests reveal a non-existent or old version of mh-e, please
-consider obtaining a new version. You can have your system
-administrator upgrade the system-wide version, or you can install your
-own personal version. It's really quite easy; instructions for getting

-message in a temporary buffer:
-
-@example
-I'm going to create the standard MH path for you.
-@end example
-
-Therefore, if you've never run MH before and you're using an old version

+@cindex MH-E, versions
+@cindex history
+@cindex versions of MH-E
+
+Because there are many old versions of MH-E out there, it is important
+to know which version you have. I'll be talking about @w{Version 8}
+which is pretty close to @w{Version 6} and @w{Version 7}. It differs
+from @w{Version 4} and @w{Version 5} and is vastly different from
+@w{Version 3}. @xref{History}.
+
+@findex mh-version
+
+To determine which version of MH-E that you have, enter @kbd{M-x
+mh-version @key{RET}}. Hopefully it says that you're running
+@w{Version @value{VERSION}} which is the latest version as of this
+printing.
+
+If your version is much older than this, please consider upgrading.
+You can have your system administrator upgrade the system-wide
+version, or you can install your own personal version. It's really
+quite easy. @xref{Getting MH-E}, for instructions for getting and
+installing MH-E.
+
+If the @code{mh-version} command displays @samp{No MH variant
+detected}@footnote{In very old versions of MH-E, you may get the error
+message, @samp{Cannot find the commands `inc' and `mhl' and the file
+`components'} if MH-E can't find MH. In this case, you need to update
+MH-E, and you may need to install MH too. However, newer versions of
+MH-E are better at finding MH if it is on your system.}, then you need
+to install MH or tell MH-E where to find MH.
+
+@cindex Debian
+@cindex nmh
+@cindex GNU mailutils
+
+If you don't have MH on your system already, you must install a
+variant of MH. The Debian mh-e package does this for you automatically
+(@pxref{Getting MH-E}). Most people use
+@uref{http://www.nongnu.org/nmh/, nmh}, but you may be interested in
+trying out @uref{http://www.gnu.org/software/mailutils/, GNU
+mailutils}, which supports IMAP. Your GNU/Linux distribution probably
+has packages for both of these.
+
+@cindex @command{install-mh}
+@cindex MH commands, @command{install-mh}

+
+If you've never run MH before, you need to run @command{install-mh}
+from the shell before you continue. This sets up your personal MH
+environment@footnote{See the section
+@uref{@value{MH-BOOK-HOME}/../overall/setup.html, Setting Up MH} in the
+MH book.}. If you don't, you'll be greeted with the error message:
+@samp{Install MH and run install-mh before running MH-E}. This is all
+you need to know about MH to use MH-E, but the more you know about MH,
+the more you can leverage its power. See the

+Your MH environment includes your @dfn{MH profile} which is found in
+the file @file{~/.mh_profile}. This file contains a number of @dfn{MH

+component contains the path to your mail directory, which is

+@vindex mh-variant-in-use
+
+There are several options MH-E uses to interact with your MH
+installation. The option @code{mh-variant} specifies the variant used
+by MH-E (@pxref{Options}). The default setting of this option is
+@samp{Auto-detect} which means that MH-E will automatically choose the
+first of nmh, MH, or GNU mailutils that it finds in the directories
+listed in @code{mh-path} (which you can customize),
+@code{mh-sys-path}, and @code{exec-path}. If MH-E can't find MH at
+all, you may have to customize @code{mh-path} and add the directory in
+which the command @command{mhparam} is located. If, on the other hand,
+you have both nmh and mailutils installed (for example) and
+@code{mh-variant-in-use} was initialized to nmh but you want to use
+mailutils, then you can set @code{mh-variant} to @samp{mailutils}.

-The @samp{~} notation used by @file{~/.emacs} above represents your home
-directory. This is used by the @code{bash} and @code{csh} shells. If
-your shell does not support this feature, you could use the environment
-variable @samp{$HOME} (such as @file{$HOME/.emacs}) or the absolute path
-(as in @file{/home/wohler/.emacs}) instead.
+This chapter introduces some of the terms you'll need to know and then
+takes you on a tour of MH-E@footnote{The keys mentioned in these
+chapters refer to the default key bindings. If you've changed the
+bindings, refer to the command summaries at the beginning of each
+chapter for a mapping between default key bindings and function
+names.}. When you're done, you'll be able to send, read, and file
+mail, which is all that a lot of people ever do. But if you're the
+curious or adventurous type, read the rest of the manual to be able to
+use all the features of MH-E. I suggest you read this chapter first to
+get the big picture, and then you can read the manual as you wish.

+Options can also hold boolean values. In Emacs Lisp, the boolean

+true. The @code{customize-option} function makes it easy to change
+boolean values; simply click on the toggle button in the customize
+buffer to switch between @samp{on} (@code{t}) and @samp{off}
+(@code{nil}). For example, try setting @code{mh-bury-show-buffer-flag}

+stack. Use the @samp{State} combo box and choose @samp{Set for Current

+
+The command @key{RET} (@code{mh-show}) displays the message that the
+cursor is on while @kbd{Mouse-2} (@code{mh-show-mouse}) displays the
+message that the mouse cursor is on. If the message is already
+displayed, it scrolls to the beginning of the message. Use @key{SPC}
+(@code{mh-page-msg}) and @key{BS} (@code{mh-previous-page}) to move
+forwards and backwards one page at a time through the message. You can
+give either of these commands a prefix argument that specifies the
+number of lines to scroll (such as @kbd{10 @key{SPC}}). The @key{SPC}
+command will also show the next undeleted message if it is used at the
+bottom of a message. MH-E normally hides a lot of the superfluous
+header fields that mailers add to a message, but if you wish to see
+all of them, use the command @kbd{,} (comma;
+@code{mh-header-display}).
+
+@vindex mh-show-maximum-size
+
+The option @code{mh-show-maximum-size} provides an opportunity to skip
+over large messages which may be slow to load. The default value of 0
+means that all message are shown regardless of size.
+
+A litany of options control what displayed messages look like.

+@vindex mh-show-date
+@vindex mh-show-from
+@vindex mh-show-header
+@vindex mh-show-subject
+@vindex mh-show-to
+
+First, the appearance of the header fields can be modified by
+customizing the associated face: @code{mh-show-to}, @code{mh-show-cc},
+@code{mh-show-from}, @code{mh-show-date}, and @code{mh-show-subject}.
+The face @code{mh-show-header} is used to deemphasize the other, less
+interesting, header fields.
+
+@cindex regular expressions, @code{mh-invisible-header-fields}
+@vindex mh-clean-message-header-flag
+@vindex mh-invisible-header-fields
+@vindex mh-invisible-header-fields-default
+
+Normally messages are delivered with a handful of uninteresting header
+fields. These are hidden by turning on the option
+@code{mh-clean-message-header-flag} (which it is by default). The
+header fields listed in the option
+@code{mh-invisible-header-fields-default} are hidden, although you can
+check off any field that you would like to see. Header fields that you
+would like to hide that aren't listed can be added to the option
+@code{mh-invisible-header-fields} with a couple of caveats. Regular
+expressions are not allowed. Unique fields should have a @samp{:}
+suffix; otherwise, the element can be used to render invisible an
+entire class of fields that start with the same prefix. If you think a
+header field should be generally ignored, report a bug (@pxref{Bug
+Reports}).
+
+@cindex header field, @samp{Face:}
+@cindex header field, @samp{X-Face:}
+@cindex header field, @samp{X-Image-URL:}
+@cindex @samp{Face:} header field
+@cindex @samp{X-Face:} header field
+@cindex @samp{X-Image-URL:} header field
+@vindex mh-show-use-xface-flag
+
+MH-E can display the content of @samp{Face:}, @samp{X-Face:}, and
+@samp{X-Image-URL:} header fields. If any of these fields occur in the
+header of your message, the sender's face will appear in the
+@samp{From:} header field. If more than one of these fields appear,
+then the first field found in the order @samp{Face:}, @samp{X-Face:},
+and @samp{X-Image-URL:} will be used. The option
+@code{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
+@samp{Face:} field@footnote{The @samp{Face:} field appeared in GNU
+Emacs 21 and XEmacs. For more information, see
+@uref{http://quimby.gnus.org/circus/face/}.}.
+
+@cindex @command{uncompface}
+@cindex Emacs, packages, x-face
+@cindex Unix commands, @command{uncompface}
+@cindex x-face package
+@vindex mh-show-xface
+
+Next is the traditional @samp{X-Face:} header field@footnote{The
+display of this field requires the
+@uref{ftp://ftp.cs.indiana.edu/pub/faces/compface/compface.tar.Z,
+@command{uncompface} program}. Recent versions of XEmacs have internal
+support for @samp{X-Face:} images. If your version of XEmacs does not,
+then you'll need both @command{uncompface} and the
+@uref{ftp://ftp.jpl.org/pub/elisp/, @samp{x-face} package}.}. MH-E
+renders the foreground and background of the image using the
+associated attributes of the face @code{mh-show-xface}.
+
+@cindex @command{convert}
+@cindex @command{wget}
+@cindex ImageMagick
+@cindex Unix commands, @command{convert}
+@cindex Unix commands, @command{wget}
+@vindex mh-fetch-x-image-url
+
+Finally, MH-E will display images referenced by the
+@samp{X-Image-URL:} header field if neither the @samp{Face:} nor the
+@samp{X-Face:} fields are present@footnote{The display of the images
+requires the @uref{http://www.gnu.org/software/wget/wget.html,
+@command{wget} program} to fetch the image and the @command{convert}
+program from the @uref{http://www.imagemagick.org/, ImageMagick
+suite}.}. 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 @code{mh-fetch-x-image-url}
+controls the fetching of the @samp{X-Image-URL:} header field image
+with the following values:
+
+@table @samp
+@item Ask Before Fetching
+You are prompted before the image is fetched. MH-E will remember your
+reply and will either use the already fetched image the next time the
+same URL is encountered or silently skip it if you didn't fetch it the
+first time. This is a good setting.
+@c -------------------------
+@item Never Fetch
+Images are never fetched and only displayed if they are already
+present in the cache. This is the default.
+@end table
-@table @kbd
-@item C-c C-y
-Insert contents of message to which you're replying (@code{mh-yank-cur-msg}).
+There isn't a value of @samp{Always Fetch} for privacy and DOS (denial
+of service) reasons. For example, fetching a URL can tip off a spammer
+that you've read his email (which is why you shouldn't blindly answer
+yes if you've set this option to @samp{Ask Before Fetching}). Someone
+may also flood your network and fill your disk drive by sending a
+torrent of messages, each specifying a unique URL to a very large
+file.
-@item C-c C-i
-Insert a message from a folder (@code{mh-insert-letter}).
+@cindex @file{.mhe-x-image-cache}
+@cindex files, @file{.mhe-x-image-cache}
+
+The cache of images is found in the directory
+@file{.mhe-x-image-cache} within your MH directory. You can add your
+own face to the @samp{From:} field too. @xref{Picture}.
+
+@cindex @command{mhl}
+@cindex MH commands, @command{mhl}
+@vindex mh-mhl-format-file
+
+Normally MH-E takes care of displaying messages itself (rather than
+calling an MH program to do the work). If you'd rather have
+@command{mhl} display the message (within MH-E), change the option
+@code{mh-mhl-format-file} from its default value of @samp{Use Default
+mhl Format (Printing Only)}. You can set this option to @samp{Use
+Default mhl Format} to get the same output as you would get if you ran
+@command{mhl} from the shell. If you have a format file that you want
+MH-E to use, you can set this option to @samp{Specify an mhl Format
+File} and enter the name of your format file (@command{mhl}(1) or
+section @uref{@value{MH-BOOK-HOME}/shomes.html#Usisho, Using mhl} in
+the MH book tells you how to write one). Your format file should
+specify a non-zero value for @samp{overflowoffset} to allow MH-E to
+parse the header. Note that @command{mhl} is always used for printing
+and forwarding; in this case, the value of @code{mh-mhl-format-file}
+is consulted if you have specified a format file.
+
+@cindex citations, highlighting
+@cindex highlighting citations
+@vindex mh-highlight-citation-style
+
+If the sender of the message has cited other messages in his message,
+then MH-E will highlight these citations to emphasize the sender's
+actual response. The option @code{mh-highlight-citation-style} can be
+customized to change the highlighting style. The @samp{Multicolor}
+method uses a different color for each indentation while the
+@samp{Monotone} method highlights all citations in red. To disable
+highlighting of citations entirely, choose @samp{None}.

+@cindex links, following
+@findex goto-address-at-point
+@kindex C-c @key{RET}
+@kindex Mouse-2
+@vindex goto-address-highlight-p
+
+Email addresses and URLs in the message are highlighted if the option
+@code{goto-address-highlight-p} is on, which it is by default. To view
+the web page for a highlighted URL or to send a message using a
+highlighted email address, use @kbd{Mouse-2} or @kbd{C-c @key{RET}}
+(@code{goto-address-at-point}). @xref{Sending Mail}, to see how to
+configure Emacs to send the message using MH-E.
+
+@cindex boldface, showing
+@cindex emphasis
+@cindex italics, showing
+@cindex smileys
+@cindex typesetting
+@cindex underline, showing
+@vindex gnus-emphasis-alist
+@vindex mh-decode-mime-flag
+@vindex mh-graphical-emphasis-flag
+@vindex mh-graphical-smileys-flag
+
+It is a long standing custom to inject body language using a
+cornucopia of punctuation, also known as the @dfn{smileys}. MH-E can
+render these as graphical widgets if the option
+@code{mh-graphical-smileys-flag} is turned on, which it is by default.
+Smileys include patterns such as :-) and ;-). Similarly, a few
+typesetting features are indicated in ASCII text with certain
+characters. If your terminal supports it, MH-E can render these
+typesetting directives naturally if the option
+@code{mh-graphical-emphasis-flag} is turned on, which it is by
+default. For example, _underline_ will be
+@ifhtml
+@html
+<u>underlined</u>,
+@end html
+@end ifhtml
+@ifnothtml
+underlined,
+@end ifnothtml
+*bold* will appear in @b{bold}, /italics/ will appear in @i{italics},
+and so on. See the option @code{gnus-emphasis-alist} for the whole
+list. Both of these options are disabled if the option
+@code{mh-decode-mime-flag} is turned off. @xref{Viewing Attachments}.
+
+@cindex signature separator
+@cindex vCard
+@vindex mh-show-signature
+
+MH-E normally renders signatures and vCards in italics so that the
+body of the message stands out more. MH-E depends on the presence of
+the @dfn{signature separator} (@code{"-- "}) to do this. You can also
+customize the face @code{mh-show-signature} so the appearance of the
+signature block is more to your liking.
+
+@vindex mh-show-hook
+@vindex mh-show-mode-hook
+
+Two hooks can be used to control how messages are displayed. The first
+hook, @code{mh-show-mode-hook}, is called early on in the process of
+the message display. It is usually used to perform some action on the
+message's content. The second hook, @code{mh-show-hook}, is the last
+thing called after messages are displayed. It's used to affect the
+behavior of MH-E in general or when @code{mh-show-mode-hook} is too
+early.

+MH has the ability to display @dfn{@sc{mime}} (Multipurpose Internet

+@command{show}@footnote{See the section

+the MH book.} from the shell to read @sc{mime} messages@footnote{You
+can call them directly from Emacs if you're running the X Window

+@cindex mm-decode package
+@findex mh-toggle-mh-decode-mime-flag
+@kindex ; (semicolon)
+@vindex mh-decode-mime-flag
+
+MH-E can handle attachments as well if the Gnus @samp{mm-decode}
+package is present. If so, the option @code{mh-decode-mime-flag} will
+be on. Otherwise, you'll see the @sc{mime} body parts rather than text
+or attachments. There isn't much point in turning off the option
+@code{mh-decode-mime-flag}; however, you can inspect it if it appears
+that the body parts are not being interpreted correctly or toggle it
+with the command @kbd{;} (semicolon;
+@code{mh-toggle-mh-decode-mime-flag}) to view the raw message. This
+option also controls the display of quoted-printable messages and
+other graphical widgets. @xref{Viewing}.
+
+@cindex buttons
+
+Attachments in MH-E are indicated by @dfn{buttons} like this:
-@item C-c C-f C-d
-Move to @samp{Dcc:} header field (@code{mh-to-field}).
+@smallexample
+[1. image/jpeg; foo.jpg]...
+@end smallexample

+@findex mh-next-button
+@findex mh-press-button
+@findex mh-prev-button
+@kindex @key{RET}
+@kindex K @key{TAB}
+@kindex K S-@key{TAB}
+@kindex Mouse-1
+@kindex Mouse-2
+
+To view the contents of the button, use either @kbd{Mouse-1} or
+@kbd{Mouse-2} on the button or @key{RET} (@code{mh-press-button}) when
+the cursor is over the button. This command is a toggle so if you use
+it again on the same attachment, it is hidden. If Emacs does not know
+how to display the attachment, then Emacs offers to save the
+attachment in a file. To move the cursor to the next button, use the
+command @kbd{K @key{TAB}} (@code{mh-next-button}). If the end of the
+buffer is reached then the search wraps over to the start of the
+buffer. To move the cursor to the previous button, use the command
+@kbd{K S-@key{TAB}} (@code{mh-prev-button}). If the beginning of the
+buffer is reached then the search wraps over to the end of the buffer.
+
+@cindex attachments, viewing
+@cindex viewing attachments
+@findex mh-folder-toggle-mime-part
+@kindex K v
+
+Another way to view the contents of a button is to use the command
+@kbd{K v} (@code{mh-folder-toggle-mime-part}). This command displays
+(or hides) the attachment associated with the button under the cursor.
+If the cursor is not located over a button, then the cursor first
+moves to the next button, wrapping to the beginning of the message if
+necessary. This command has the advantage over the previous commands
+of working from the MH-Folder buffer. You can also provide a numeric
+prefix argument (as in @kbd{4 K v}) to view the attachment labeled
+with that number. If Emacs does not know how to display the
+attachment, then Emacs offers to save the attachment in a file.

+@kindex K e
+
+If Emacs does not know how to view an attachment, you could save it
+into a file and then run some program to open it. It is easier,
+however, to launch the program directly from MH-E with the command
+@kbd{K e} (@code{mh-display-with-external-viewer}). While you'll most
+likely use this to view spreadsheets and documents, it is also useful
+to use your browser to view HTML attachments with higher fidelity than
+what Emacs can provide. This command displays the attachment
+associated with the button under the cursor. If the cursor is not
+located over a button, then the cursor first moves to the next button,
+wrapping to the beginning of the message if necessary. You can provide
+a numeric prefix argument (as in @kbd{4 K e}) to view the attachment
+labeled with that number. This command tries to provide a reasonable
+default for the viewer by calling the Emacs function
+@code{mailcap-mime-info}. This function usually reads the file
+@file{/etc/mailcap}.

+@cindex attachments, saving
+@cindex saving attachments
+@findex mh-folder-save-mime-part
+@kindex K o
+
+Use the command @kbd{K o} (@code{mh-folder-save-mime-part}) to save
+attachments (the mnemonic is ``output''). This command saves the
+attachment associated with the button under the cursor. If the cursor
+is not located over a button, then the cursor first moves to the next
+button, wrapping to the beginning of the message if necessary. You can
+also provide a numeric prefix argument (as in @kbd{3 K o}) to save the
+attachment labeled with that number. This command prompts you for a
+filename and suggests a specific name if it is available.

+@kindex K a
+@vindex mh-mime-save-parts-default-directory
+
+You can save all of the attachments at once with the command @kbd{K a}
+(@code{mh-mime-save-parts}). The attachments are saved in the
+directory specified by the option
+@code{mh-mime-save-parts-default-directory} unless you use a prefix
+argument (as in @kbd{C-u K a}) in which case you are prompted for the
+directory. These directories may be superseded by MH profile
+components, since this function calls on @command{mhstore}
+(@command{mhn}) to do the work.
+
+@vindex mh-mime-save-parts-default-directory
+
+The default value for the option
+@code{mh-mime-save-parts-default-directory} is @samp{Prompt Always} so
+that you are always prompted for the directory in which to save the
+attachments. However, if you usually use the same directory within a
+session, then you can set this option to @samp{Prompt the First Time}
+to avoid the prompt each time. you can make this directory permanent
+by choosing @samp{Directory} and entering the directory's name.

+@cindex inline attachments
+@findex mh-toggle-mime-buttons
+@kindex K t
+@vindex mh-display-buttons-for-inline-parts-flag
+
+The sender can request that attachments should be viewed inline so
+that they do not really appear like an attachment at all to the
+reader. Most of the time, this is desirable, so by default MH-E
+suppresses the buttons for inline attachments. On the other hand, you
+may receive code or HTML which the sender has added to his message as
+inline attachments so that you can read them in MH-E. In this case, it
+is useful to see the buttons so that you know you don't have to cut
+and paste the code into a file; you can simply save the attachment. If
+you want to make the buttons visible for inline attachments, you can
+use the command @kbd{K t} (@code{mh-toggle-mime-buttons}) to toggle
+the visibility of these buttons. You can turn on these buttons
+permanently by turning on the option
+@code{mh-display-buttons-for-inline-parts-flag}.
+
+MH-E cannot display all attachments inline however. It can display
+text (including @sc{html}) and images.
+
+@cindex header field, @samp{Content-Disposition:}
+@cindex inline images
+@cindex @samp{Content-Disposition:} header field
+@vindex mh-max-inline-image-height
+@vindex mh-max-inline-image-width
+
+Some older mail programs do not insert the needed
+plumbing@footnote{This plumbing is the @samp{Content-Disposition:}
+header field.} to tell MH-E whether to display the attachments inline
+or not. If this is the case, MH-E will display these images inline if
+they are smaller than the window. However, you might want to allow
+larger images to be displayed inline. To do this, you can change the
+options @code{mh-max-inline-image-width} and
+@code{mh-max-inline-image-height} from their default value of zero to
+a large number. The size of your screen is a good choice for these
+numbers.
+
+@cindex alternatives
+@cindex attachments, alternatives
+@vindex mh-display-buttons-for-alternatives-flag
+
+Sometimes, a mail program will produce multiple alternatives of an
+attachment in increasing degree of faithfulness to the original
+content. By default, only the preferred alternative is displayed. If
+the option @code{mh-display-buttons-for-alternatives-flag} is on, then
+the preferred part is shown inline and buttons are shown for each of
+the other alternatives.
+
+@vindex mm-discouraged-alternatives
+
+Many people prefer to see the @samp{text/plain} alternative rather
+than the @samp{text/html} alternative. To do this in MH-E, customize
+the option @code{mm-discouraged-alternatives}, and add
+@samp{text/html}. The next best alternative, if any, will be shown.
+
+@kindex K i
+@findex mh-folder-inline-mime-part
+
+You can view the raw contents of an attachment with the command @kbd{K
+i} (@code{mh-folder-inline-mime-part}). This command displays (or
+hides) the contents of the attachment associated with the button under
+the cursor verbatim. If the cursor is not located over a button, then
+the cursor first moves to the next button, wrapping to the beginning
+of the message if necessary. You can also provide a numeric prefix
+argument (as in @kbd{4 K i}) to view the attachment labeled with that
+number.

+content of the message will appear in the MH-Show buffer as you would
+expect if the entire message is HTML, or there is an inline HTML body

+then you'll see a button like this:

+@vindex mm-text-html-renderer
+
+The browser that MH-E uses is determined by the option
+@code{mm-text-html-renderer}. The default setting is set automatically
+based upon the presence of a known browser on your system. If you wish
+to use a different browser, then set this option accordingly. See the
+documentation for the browser you use for additional information on
+how to use it. In particular, find and disable the option to render
+images as this can tip off spammers that the email address they have
+used is valid.
+
+@vindex mm-text-html-renderer
+
+If you're confused about which @code{mm-text-html-renderer} to use,
+here's a brief description of each, sorted by popularity, that
+includes the results of a quick poll of MH-E users from 2005-12-23.
+
+@table @asis
+@cindex browser, @samp{w3m}
+@cindex @samp{w3m}
+@kindex Mouse-2
+@kindex S-Mouse-2
+@item @samp{w3m} 7
+The @samp{w3m} browser requires an external program. It's quick,
+produces pretty nice output, and best of all, it's the only browser
+that highlights links. These can be clicked with @kbd{Mouse-2} to view
+the content of the link in @samp{w3m} or with @kbd{S-Mouse-2} to view
+the content of the link in an external browser. The @samp{w3m} browser
+handles tables well and actually respects the table's width parameter
+(which can cause text to wrap if the author didn't anticipate that the
+page would be viewed in Emacs).
+@c -------------------------
+@cindex browser, @samp{w3m-standalone}
+@cindex @samp{w3m-standalone}
+@item @samp{w3m-standalone} 3
+This browser, along with @samp{nil} for the external browser, are the
+only choices that work without having to download a separate lisp
+package or external program. This browser is quick, but does not show
+links. It handles simple tables but some tables get rendered much
+wider than the Emacs frame. This browser was the only one not to
+handle the escape @samp{–} (it printed a @samp{?}), but it did
+render @samp{®}.
+@c -------------------------
+@cindex browser, @samp{links}
+@cindex @samp{links}
+@item @samp{links} 1
+The @samp{links} browser requires an external program. It's quick, and
+produces nicer output than @samp{lynx} on single column mails in
+tables. However, it doesn't show links and it doesn't do as nice a job
+on multi-column tables as some lines wrap. At least it fits in 80
+columns and thus seems better than @samp{w3} and
+@samp{w3m-standalone}. Converts escapes such as @samp{®} to (R).
+@c -------------------------
+@cindex browser, @samp{lynx}
+@cindex @samp{lynx}
+@item @samp{lynx} 1
+The @samp{lynx} browser requires an external program. It's quick and
+produces pretty decent output but it doesn't show links. It doesn't
+seem to do multi-column tables which makes output much cleaner. It
+centers the output and wraps long lines more than most. Handles
+@samp{®}.
+@c -------------------------
+@item @samp{nil} 1
+This choice obviously requires an external browser. Like
+@samp{w3m-standalone}, it works out of the box. With this setting,
+HTML messages have a button for the body part which you can view with
+@kbd{K v} (@code{mh-folder-toggle-mime-part}).
+@c -------------------------
+@cindex browser, @samp{w3}
+@cindex @samp{w3}
+@item @samp{w3} 0
+This choice does not require an external program as all of the
+rendering is done in lisp. You do need to get the package separately.
+This browser is @strong{slow}, and doesn't appear to have been updated
+since 2001 and the author hasn't responded to my emails. It displays
+unknown tags instead of hiding them, so you get to see all the
+Microsoft crap in certain messages. Tends to make multi-column tables
+wider than even a full-screen Emacs can handle. Like @samp{w3m}, you
+can follow links, but you have to find them first as they are not
+highlighted. Performs well on single-column tables and handles escapes
+such as @samp{®}.
+@c -------------------------
+@cindex browser, @samp{html2text}
+@cindex @samp{html2text}
+@item @samp{html2text} 0
+The @samp{html2text} browser requires an external program. I noticed
+that it can do some nasty things with simple HTML mails (like filling
+the entire message as if it were one paragraph, including signature).
+On another message, it displayed half of the HTML tags for some
+reason.

+
+A digest is a message that contains other messages. Special MH-E

+@key{BS} to page through the digest as if it were a normal message,
+but if you wish to skip to the next message in the digest, use

+Another handy command is @kbd{D b} (@code{mh-burst-digest}). This
+command uses the MH command @command{burst}@footnote{See the section
+@uref{@value{MH-BOOK-HOME}/burdig.html, Bursting Messages} in the MH
+book.} to break out each message in the digest into its own message.
+Using this command, you can quickly delete unwanted messages, like
+this: Once the digest is split up, toggle out of MH-Folder Show mode
+with @kbd{t} (@pxref{Folders}) so that the scan lines fill the screen
+and messages aren't displayed. Then use @kbd{d} (@pxref{Reading Mail})
+to quickly delete messages that you don't want to read (based on the
+@samp{Subject:} header field). You can also burst the digest to reply
+directly to the people who posted the messages in the digest. One
+problem you may encounter is that the @samp{From:} header fields are
+preceded with a @samp{>} so that your reply can't create the
+@samp{To:} field correctly. In this case, you must correct the
+@samp{To:} field yourself. This is described later (@pxref{Editing

+
+An alternative to using the @samp{ps-print} package is the command
+@kbd{P l} (@code{mh-print-msg}) (the @i{l} is for @i{l}ine printer or
+@i{l}pr). You can print all the messages in a range. The message is
+formatted with @command{mhl}@footnote{See the section
+@uref{@value{MH-BOOK-HOME}/shomes.html#Usisho, Using mhl} in the MH
+book.} and printed with the @command{lpr} command.
+
+@kindex P f
+@kindex P l
+@kindex P p
+@vindex mh-lpr-command-format
+@vindex mh-print-background-flag
+
+The command @kbd{P l} uses two options. The option
+@code{mh-lpr-command-format} contains the Unix command line which
+performs the actual printing. The string can contain one escape,
+@samp{%s}, which is replaced by the name of the folder and the message
+number and is useful for print job names. The default setting is
+@code{"lpr -J '%s'"}. I use @code{"mpage -h'%s' -b Letter -H1of -mlrtb
+-P"} which produces a nice header and adds a bit of margin so the text
+fits within my printer's margins. Normally messages are printed in the
+foreground. If this is slow on your system, you may elect to turn on
+the option @code{mh-print-background-flag} to print in the background.
+If you do this, do not delete the message until it is printed or else
+the output may be truncated. These options are not used by the
+commands @kbd{P p} or @kbd{P f}.

+MH-E does offer a couple of commands that are not a part of MH@. The
+first one, @kbd{>} (@code{mh-write-msg-to-file}), writes a message to
+a file. You are prompted for the filename. If the file already exists,
+the message is appended to it. You can also write the message to the
+file without the header by specifying a prefix argument (such as
+@kbd{C-u > /tmp/foobar @key{RET}}). Subsequent writes to the same file

+You can also pipe the message through a Unix shell command with the

+command through which you wish to run your message. If you give a
+prefix argument to this command, the message header is included in the
+text passed to the command (the contrived example @kbd{C-u | lpr}

-your recipient reads the message! If you were to create a multimedia
-message with plain MH commands, you would use @code{mhn}. Indeed, the

+@kbd{n} to force subsequent @kbd{d} commands to move forward to the
+next undeleted message after deleting the message under the cursor.

+(@code{mh-delete-subject-or-thread}) to delete all the messages with
+the same subject as the current message. This command puts these
+messages in a sequence named @samp{subject}. You can undo this action
+by using @kbd{u} (@code{mh-undo}) with a prefix argument and then

+The hook @code{mh-folder-mode-hook} is called when visiting a new

+
+@smalllisp
+@group
+(defvar my-mh-init-done nil
+ "Non-@code{nil} when one-time MH-E settings made.")

+
+MH-E has analogies for each of the MH @command{folder} and
+@command{refile} commands@footnote{See the sections
+@uref{@value{MH-BOOK-HOME}/fol.html#Youfol, Your Current Folder:
+folder} and @uref{@value{MH-BOOK-HOME}/fol.html#Movref, Moving and
+Linking Messages: refile} in the MH book.}. To refile a message in
+another folder, use the command @kbd{o} (@code{mh-refile-msg})
+(mnemonic: ``output''). You are prompted for the folder name
+(@pxref{Folder Selection}). Note that this command can also be used to
+create folders. If you specify a folder that does not exist, you will
+be prompted to create it. The hook @code{mh-refile-msg-hook} is called
+after a message is marked to be refiled.
+
+@findex mh-write-msg-to-file
+@kindex !
+
+If you are refiling several messages into the same folder, you can use
+the command @kbd{!} (@code{mh-refile-or-write-again}) to repeat the
+last refile or write (for the description of @kbd{>}
+(@code{mh-write-msg-to-file}), @pxref{Files and Pipes}). You can use a
+range in either case (for example, @kbd{C-u o 1 3 5-7 last:5 frombob
+@key{RET}}, @pxref{Ranges}).
+
+@cindex expunging refiles and deletes
+@cindex undoing refiles and deletes
+@findex mh-undo
+@kindex u
+
+If you've deleted a message or refiled it, but changed your mind, you
+can cancel the action before you've executed it. Use @kbd{u}
+(@code{mh-undo}) to undo a refile on or deletion of a single message.
+You can also undo refiles and deletes for messages that are found in a
+given range (@pxref{Ranges}).
+
+@findex mh-undo-folder
+@kindex F u
+
+Alternatively, you can use @kbd{F u} (@code{mh-undo-folder}) to undo
+all refiles and deletes in the current folder.
+
+@findex mh-execute-commands
+@kindex x
+
+If you've marked messages to be deleted or refiled and you want to go
+ahead and delete or refile the messages, use @kbd{x}
+(@code{mh-execute-commands}). Many MH-E commands that may affect the
+numbering of the messages (such as @kbd{F r} or @kbd{F p}) will ask if
+you want to process refiles or deletes first and then either run
+@kbd{x} for you or undo the pending refiles and deletes.
+
+@kindex x
+@vindex mh-after-commands-processed-hook
+@vindex mh-before-commands-processed-hook
+
+The command @kbd{x} runs @code{mh-before-commands-processed-hook}
+before the commands are processed and
+@code{mh-after-commands-processed-hook} after the commands are
+processed. Variables that are useful with the former hook include
+@code{mh-delete-list} and @code{mh-refile-list} which can be used to
+see which changes will be made to the current folder,
+@code{mh-current-folder}. Variables that are useful with the latter
+hook include @code{mh-folders-changed}, which lists which folders were
+affected by deletes and refiles. This list will always include the
+current folder @code{mh-current-folder}.
+
+@findex mh-copy-msg
+@kindex c
+@kindex o
+
+If you wish to copy a message to another folder, you can use the
+command @kbd{c} (@code{mh-copy-msg}) (see the @option{-link} argument
+to @command{refile}(1)). Like the command @kbd{o}, this command
+prompts you for the name of the target folder and you can specify a
+range (@pxref{Ranges}). Note that unlike the command @kbd{o}, the copy
+takes place immediately. The original copy remains in the current
+folder.

+
+The command @kbd{t} (@code{mh-toggle-showing}) switches between
+MH-Folder mode and MH-Folder Show mode@footnote{For you Emacs wizards,
+this is implemented as an Emacs minor mode.}. MH-Folder mode turns off
+the associated show buffer so that you can perform operations on the
+messages quickly without reading them. This is an excellent way to
+prune out your junk mail or to refile a group of messages to another
+folder for later examination.

+@vindex mh-recenter-summary-flag
+
+When you use @kbd{t} to toggle from MH-Folder Show mode to MH-Folder
+mode, the MH-Show buffer is hidden and the MH-Folder buffer is left
+alone. Setting @code{mh-recenter-summary-flag} to a non-@code{nil}
+value causes the toggle to display as many scan lines as possible,
+with the cursor at the middle. The effect of
+@code{mh-recenter-summary-flag} is rather useful, but it can be
+annoying on a slow network connection.
+
+@findex mh-visit-folder
+@kindex F v
+@vindex mh-large-folder
+
+When you want to read the messages that you have refiled into folders,
+use the command @kbd{F v} (@code{mh-visit-folder}) to visit the
+folder. You are prompted for the folder name. The folder buffer will
+show just unseen messages if there are any; otherwise, it will show
+all the messages in the buffer as long there are fewer than
+@code{mh-large-folder} messages. If there are more, then you are
+prompted for a range of messages to scan. You can provide a prefix
+argument in order to specify a range of messages to show when you
+visit the folder (@pxref{Ranges}). In this case, regions are not used
+to specify the range and @code{mh-large-folder} is ignored. Note that
+this command can also be used to create folders. If you specify a
+folder that does not exist, you will be prompted to create it.

+
+If you use a program such as @command{procmail} to file your incoming

+command @kbd{F n} (@code{mh-index-new-messages}). All messages in the
+@samp{unseen} sequence from the folders in
+@code{mh-new-messages-folders} are listed. However, this list of
+folders can be overridden with a prefix argument: with a prefix
+argument, enter a space-separated list of folders, or nothing to

+using the command @kbd{F '} (@code{mh-index-ticked-messages}). All
+messages in the @samp{tick} sequence from the folders in

+enter a space-separated list of folders, or nothing to search all
+folders.
+
+@findex mh-index-sequenced-messages
+@kindex F q
+@vindex mh-new-messages-folders
+
+You can display messages in any sequence with the command @kbd{F q}

+@code{mh-new-messages-folders} in the sequence you provide are listed.
+With a prefix argument, enter a space-separated list of folders at the

+
+@vindex mh-new-messages-folders

+@vindex mh-ticked-messages-folders
+
+Set the options @code{mh-new-messages-folders} and
+@code{mh-ticked-messages-folders} to @samp{Inbox} to search the
+@samp{+inbox} folder or @samp{All} to search all of the top level

+your mail directory in a buffer called @samp{*MH-E Folders*}
+(@pxref{Miscellaneous}); @kbd{F k} (@code{mh-kill-folder}), to remove

+@kbd{F p} (@code{mh-pack-folder}), to pack a folder, removing gaps

+to rescan the folder, which is useful to grab all messages in your
+@samp{+inbox} after processing your new mail for the first time. If

+@kbd{F p} will accept a range (@pxref{Ranges}).
+
+@kindex @key{TAB}
+@vindex mh-recursive-folders-flag
+
+By default, operations on folders work only one level at a time. Set
+@code{mh-recursive-folders-flag} to non-@code{nil} to operate on all

+when you press @key{TAB} when prompted for a folder name.
+
+@findex mh-search-p
+@kindex k
+@vindex mh-kill-folder-suppress-prompt-hooks
+
+The hook @code{mh-kill-folder-suppress-prompt-hooks} is an abnormal
+hook run at the beginning of the command @kbd{k}. The hook functions
+are called with no arguments and should return a non-nil value to
+suppress the normal prompt when you remove a folder. This is useful
+for folders that are easily regenerated. The default value of
+@code{mh-search-p} suppresses the prompt on folders generated by

+@findex mh-quit
+@kindex q
+
+When you want to quit using MH-E and go back to editing, you can use
+the @kbd{q} (@code{mh-quit}) command. This buries the buffers of the
+current MH-E folder and restores the buffers that were present when
+you first ran @kbd{M-x mh-rmail}. It also removes any MH-E working
+buffers whose name begins with @samp{ *mh-} or @samp{*MH-E }
+(@pxref{Miscellaneous}). You can later restore your MH-E session by
+selecting the @samp{+inbox} buffer or by running @kbd{M-x mh-rmail}

+The two hooks @code{mh-before-quit-hook} and @code{mh-quit-hook} are

+you might use it to perform any MH-E operations; you could perform
+some query and abort the quit or call @code{mh-execute-commands}, for
+example. The latter is not run in an MH-E context, so you might use it
+to modify the window setup. If you find that @kbd{q} buries a lot of

+@code{mh-before-quit-hook} and @code{mh-quit-hook} to accomplish that.

+Two hooks are provided to run commands on your freshly created draft.
+The first hook, @code{mh-letter-mode-hook}, allows you to do some
+processing before editing a letter@footnote{Actually, because
+MH-Letter mode inherits from Mail mode, the hooks
+@code{text-mode-hook} and @code{mail-mode-hook} are run (in that
+order) before @code{mh-letter-mode-hook}.}. For example, you may wish
+to modify the header after @command{repl} has done its work, or you
+may have a complicated @file{components} file and need to tell MH-E
+where the cursor should go. Here's an example of how you would use
+this hook.

+The second hook, a function really, is

+Because the header is part of the message, you can edit the header
+fields as you wish. However, several convenience commands exist to
+help you create and edit them. For example, the command @kbd{C-c C-f
+C-t} (@code{mh-to-field}; alternatively, @kbd{C-c C-f t}) moves the
+cursor to the @samp{To:} header field, creating it if necessary. The
+commands for moving to the @samp{Cc:}, @samp{Subject:}, @samp{From:},
+@samp{Reply-To:}, @samp{Mail-Reply-To:}, @samp{Mail-Followup-To},
+@samp{Bcc:}, and @samp{Dcc:} header fields are similar.
-If at any time you receive new mail, incorporate the new mail into your
-@samp{+inbox} buffer with @kbd{i} (@code{mh-inc-folder}). Note that
-@kbd{i} will display the @samp{+inbox} buffer, even if there isn't any
-new mail. You can incorporate mail from any file into the current
-folder by specifying a prefix argument; you'll be prompted for the name
-of the file to use (for example, @kbd{C-u i ~/mbox @key{RET}}).
+@findex mh-to-fcc
+@kindex C-c C-f C-f
+@kindex C-c C-f f
+
+One command behaves differently from the others, namely, @kbd{C-c C-f
+C-f} (@code{mh-to-fcc}; alternatively, @kbd{C-c C-f f}). This command
+will prompt you for the folder name in which to file a copy of the

+@vindex mh-letter-header-field
+
+Within the header of the message, the command@* @key{TAB}
+(@code{mh-letter-next-header-field-or-indent}) moves between fields
+that are highlighted with the face @code{mh-letter-header-field},
+skipping those fields listed in
+@code{mh-compose-skipped-header-fields}. After the last field, this
+command then moves point to the message body before cycling back to
+the first field. If point is already past the first line of the
+message body, then this command indents by calling
+@code{indent-relative} with the given prefix argument. The command
+@kbd{S-@key{TAB}} (@code{mh-letter-previous-header-field}) moves
+backwards between the fields and cycles to the body of the message
+after the first field. Unlike the command @key{TAB}, it will always
+take point to the last field from anywhere in the body.

+
+If the field contains addresses (for example, @samp{To:} or
+@samp{Cc:}) or folders (for example, @samp{Fcc:}) then the command
+@kbd{M-@key{TAB}} (@code{mh-letter-complete}) will provide alias
+completion (@pxref{Aliases}). In the body of the message,
+@kbd{M-@key{TAB}} runs @code{mh-letter-complete-function} instead,
+which is set to @samp{'ispell-complete-word} by default. The command
+@kbd{M-@key{TAB}} (@code{mh-letter-complete}) takes a prefix argument
+that is passed to the @code{mh-letter-complete-function}. In addition,
+turn on the option @code{mh-compose-space-does-completion-flag} to use
+the command @key{SPC} (@code{mh-letter-complete-or-space}) to perform
+completion in the header as well; use a prefix argument to specify
+more than one space. Addresses are separated by a comma; when you
+press the comma, the command @code{mh-letter-confirm-address} flashes
+the alias expansion in the minibuffer if
+@code{mh-alias-flash-on-comma} is turned on.
+
+@c XXX Document the replacement for the inaccessible 'long argument.
+
+@findex mh-letter-toggle-header-field-display
+@kindex C-c C-t
+
+Use the command @kbd{C-c C-t}
+@code{mh-letter-toggle-header-field-display} to display truncated
+header fields. This command is a toggle so entering it again will hide
+the field. This command takes a prefix argument: if negative then the
+field is hidden, if positive then the field is displayed (for example,
+@kbd{C-u C-c C-t}).
+
+Be sure to leave a row of dashes or a blank line between the header
+and the body of the message.
+
+@vindex mh-letter-fill-column
+
+The body of the message is edited as you would edit any Emacs buffer
+although there are a few commands and options to assist you. You can
+change the fill column in MH-Letter mode with the option
+@code{mh-letter-fill-column}. By default, this option is 72 to allow
+others to quote your message without line wrapping.
+
+@cindex filling paragraphs
+@cindex paragraphs, filling

+@kindex M-q
+@vindex mh-ins-buf-prefix
+
+You'll often include messages that were sent from user agents that
+haven't yet realized that paragraphs consist of more than a single
+line. This makes for long lines that wrap in an ugly fashion. You'll
+find that @kbd{M-q} (@code{fill-paragraph}) works well even on these
+quoted messages, even if they are nested, just as long as all of the
+quotes match the value of @code{mh-ins-buf-prefix} (@pxref{Inserting

-To mark a message for deletion, use the @kbd{d} (@code{mh-delete-msg})
-command. A @samp{D} is placed by the message in the scan window, and
-the next message is displayed. If the previous command had been
-@kbd{p}, then the next message displayed is the message previous to the
-message just deleted. If you specify a prefix argument, you will be
-prompted for a sequence (@pxref{Sequences}) to delete (for example,
-@kbd{C-u d frombob RET}). The @kbd{x} command actually carries out the
-deletion (@pxref{Finishing Up}). @kbd{C-d}

+The command @kbd{C-c C-o} (@code{mh-open-line}) is similar to the

+after point. It differs in that it also inserts the right number of
+quoting characters and spaces so that the next line begins in the same
+column as it was. This is useful when breaking up paragraphs in
+replies. For example, if this command was used when point was after
+the first period in the paragraph above, the result would be this:

+@cindex MH commands, @command{mhbuild}
+@cindex MH commands, @command{mhn}
+@cindex MIME
+@cindex multimedia mail
+
+MH-E has the capability to create multimedia messages. It uses the
+@sc{mime} (Multipurpose Internet Mail Extensions)
+protocol@footnote{@sc{mime} is defined in
+@uref{http://www.rfc-editor.org/rfc/rfc2045.txt, RFC 2045}.} The
+@sc{mime} protocol allows you to incorporate images, sound, video,
+binary files, and even commands that fetch a file with @samp{ftp} when
+your recipient reads the message!
+
+@kindex C-c C-m
+
+If you were to create a multimedia message with plain MH commands, you
+would insert @command{mhbuild} or @command{mhn} directives (henceforth
+called @dfn{MH-style directives} into your draft and use the
+@command{mhbuild} command in nmh or @command{mhn} command in MH and
+GNU mailutils to expand them. MH-E works in much the same way,
+although it provides a handful of commands prefixed with @kbd{C-c C-m}
+to insert the directives so you don't need to remember the syntax of
+them. Remember: you can always add MH-style directives by
+hand@footnote{See the section
+@uref{@value{MH-BOOK-HOME}/usimim.html#SeMIMa, Sending MIME Mail} in
+the MH book.}.
+
+@cindex MIME Meta Language (MML)
+@cindex MML
+@vindex mh-compose-insertion
+
+In addition to MH-style directives, MH-E also supports MML (@sc{mime}
+Meta Language) tags@footnote{
+@ifinfo
+@c Although the third argument should default to the
+@c first, makeinfo goes to the wrong Info file without it being
+@c different--it seems to be getting our own Composing node.
+@xref{Composing,,Composing with MML,emacs-mime}.

+@ifnotinfo
+See the section Composing in
+@uref{http://www.gnus.org/manual/emacs-mime.html, @cite{The Emacs MIME
+Manual}}.
+@end ifnotinfo
+}. The option @code{mh-compose-insertion} can be used to choose
+between them. By default, this option is set to @samp{MML} if it is
+supported since it provides a lot more functionality. This option can
+also be set to @samp{MH} if MH-style directives are preferred.
+
+@cindex media types
+@cindex MIME, media types
+
+The MH-E @sc{mime} commands require a @dfn{media type} for each body
+part or attachment. For example, a PDF document is of type
+@samp{application/pdf} and an HTML document is of type
+@samp{text/html}. Some commands fill in the media type for you,
+whereas others require you to enter one.
+
+@cindex @command{file}
+@cindex @file{/etc/mime.types}
+@cindex files, @file{/etc/mime.types}
+@cindex Unix commands, @command{file}
+@findex mailcap-mime-types
+
+In the cases where MH-E can do so, it will determine the media type
+automatically. It uses the @command{file} command to do this. Failing
+that, the Emacs function @code{mailcap-mime-types} is used to provide
+a list from which to choose. This function usually reads the file
+@file{/etc/mime.types}.
+
+Whether the media type is chosen automatically, or you choose it from
+a list, use the type that seems to match best the file that you are
+including. In the case of binaries, the media type
+@samp{application/x-executable} can be useful. If you can't find an
+appropriate media type, use @samp{text/plain} for text messages and
+@samp{application/octet-stream} for everything else.
+
+@cindex content description
+@cindex MIME, content description
+
+You are also sometimes asked for a @dfn{content description}. This is
+simply an optional brief phrase, in your own words, that describes the
+object. If you don't care to enter a content description, just press
+return and none will be included; however, a reader may skip over
+multimedia fields unless the content description is compelling.

+@key{TAB} (@code{minibuffer-complete}) command to complete aliases
+(and optionally local logins) when prompted for the recipients. Turn

+@kbd{M-@key{TAB}} (@code{mh-letter-complete}) or @key{SPC}
+(@code{mh-letter-complete-or-space}).
+
+@vindex mh-alias-completion-ignore-case-flag
+
+As MH ignores case in the aliases, so too does MH-E. However, you may
+turn off the option @code{mh-alias-completion-ignore-case-flag} to
+make case significant which can be used to segregate completion of
+your aliases. You might use uppercase for mailing lists and lowercase
+for people. For example, you might have:
-@findex @code{mh-version}
+@smallexample
+mark.baushke: Mark Baushke <mdb@@stop.mail-abuse.org>
+MH-E: MH-E Mailing List <mh-e-devel@@stop.mail-abuse.org>
+@end smallexample
-One other command worth noting is @kbd{M-x mh-version}. You can
-compare the version this command prints to the latest release
-(@pxref{Getting mh-e}). The output of @kbd{M-x mh-version} should
-always be included with any bug report you submit (@pxref{Bug Reports}).
+When this option is turned off, if you were to type @kbd{M} in the
+@samp{To:} field and then @kbd{M-@key{TAB}}, then you'd get the list;
+if you started with @kbd{m} and then entered @kbd{M-@key{TAB}}, then
+you'd get Mark's address. Note that this option affects completion
+only. If you were to enter @kbd{Mark.Baushke}, it would still be
+identified with your @samp{mark.baushke} alias.
+
+@findex mh-alias-minibuffer-confirm-address
+@findex mh-letter-confirm-address
+@vindex mh-alias-flash-on-comma
+@vindex mh-compose-prompt-flag
+
+To verify that the alias you've entered is valid, the alias will be
+displayed in the minibuffer when you type a comma
+(@code{mh-letter-confirm-address} or
+@code{mh-alias-minibuffer-confirm-address} if the option
+@code{mh-compose-prompt-flag} is turned on). @xref{Composing}. This
+behavior can be controlled with the option
+@code{mh-alias-flash-on-comma} which provides three choices:
+@samp{Flash but Don't Warn If No Alias}, @samp{Flash and Warn If No
+Alias}, and @samp{Don't Flash Nor Warn If No Alias}.
+
+For another way to verify the alias expansion, see @ref{Checking

+@cindex MH commands, @command{ali}
+@cindex MH profile component, @samp{Aliasfile:}
+@cindex files, @file{/etc/nmh/MailAliases}
+
+MH-E loads aliases for completion and folder name hints from various
+places. It uses the MH command @command{ali}@footnote{See the section
+@uref{@value{MH-BOOK-HOME}/mh.html, MH Aliases} in the MH book.} to
+read aliases from the files listed in the profile component
+@samp{Aliasfile:} as well as system-wide aliases (for example,
+@file{/etc/nmh/MailAliases}).
+
+@cindex @file{/etc/passwd}
+@cindex files, @file{/etc/passwd}
+
+In addition, aliases are created from @file{/etc/passwd} entries with
+a user ID larger than a magical number, typically 200. This can be a
+handy tool on a machine where you and co-workers exchange messages.
+These aliases have the form @samp{local.@var{first.last}} if a real
+name is present in the password file. Otherwise, the alias will have
+the form @samp{local.@var{login}}.
+
+@vindex mh-alias-local-users-prefix
+
+The prefix @samp{local.} can be modified via the option
+@code{mh-alias-local-users-prefix}. This option can also be set to
+@samp{Use Login}.
+
+For example, consider the following password file entry:
-@node Customizing mh-e, Odds and Ends, Using mh-e, Top
-@chapter Customizing mh-e
+@smallexample
+psg:x:1000:1000:Peter S Galbraith,,,:/home/psg:/bin/tcsh
+@end smallexample
-Until now, we've talked about the mh-e commands as they work ``out of the
-box.'' Of course, it is also possible to reconfigure mh-e
-to fit the needs of even the most demanding user.
-The following sections describe all of the
-customization variables, show the defaults, and make recommendations for
-customization. The outline of this chapter is identical to that of
-@ref{Using mh-e}, to make it easier to find the variables you'd need to
-modify to affect a particular command.
+@vindex mh-alias-local-users-prefix
-However, when customizing your mail environment, first try to change
-what you want in MH, and only change mh-e if changing MH is not
-possible. That way you will get the same behavior inside and outside
-GNU Emacs. Note that mh-e does not provide hooks for customizations
-that can be done in MH; this omission is intentional.
+The following settings of option @code{mh-alias-local-users-prefix}
+will produce the associated aliases:
-@cindex @file{.emacs}
-@cindex files, @file{.emacs}
+@table @code
+@item "local."
+local.peter.galbraith
+@c -------------------------
+@item ""
+peter.galbraith
+@c -------------------------
+@item Use Login
+psg
+@end table
-Many string or integer variables are easy enough to modify using Emacs
-Lisp. Any such modifications should be placed in a file called
-@file{.emacs} in your home directory (that is, @file{~/.emacs}). For
-example, to modify the variable that controls printing, you could add:
+@vindex mh-alias-passwd-gecos-comma-separator-flag
+
+In the example above, commas are used to separate different values
+within the so-called GECOS field. This is a fairly common usage.
+However, in the rare case that the GECOS field in your password file
+is not separated by commas and whose contents may contain commas, you
+can turn the option @code{mh-alias-passwd-gecos-comma-separator-flag}
+off.
+
+@cindex NIS, obtaining local aliases from
+@cindex @samp{ypcat passwd}
+@vindex mh-alias-local-users
+
+If you're on a system with thousands of users you don't know, and the
+loading of local aliases slows MH-E down noticeably, then the local
+alias feature can be disabled by turning off the option
+@code{mh-alias-local-users}. This option also takes a string which is
+executed to generate the password file. For example, use @samp{ypcat
+passwd} to obtain the NIS password file.
+
+@findex mh-alias-reload
+@kindex M-x mh-alias-reload
+@vindex mh-alias-reloaded-hook
+
+Since aliases are updated frequently, MH-E reloads aliases
+automatically whenever an alias lookup occurs if an alias source has
+changed. However, you can reload your aliases manually by calling the
+command @kbd{M-x mh-alias-reload} directly. This command runs
+@code{mh-alias-reloaded-hook} after the aliases have been loaded.
+
+@subheading Adding Aliases
+
+In the past, you have manually added aliases to your alias file(s)
+listed in your @samp{Aliasfile:} profile component. MH-E provides
+other methods for maintaining your alias file(s).
+
+@findex mh-alias-add-alias
+@kindex M-x mh-alias-add-alias
+
+You can use the @kbd{M-x mh-alias-add-alias} command which will prompt
+you for the alias and address that you would like to add. If the alias
+exists already, you will have the choice of inserting the new alias
+before or after the old alias. In the former case, this alias will be
+used when sending mail to this alias. In the latter case, the alias
+serves as an additional folder name hint when filing messages
+(@pxref{Folder Selection}).
+
+Earlier, the alias prefix @samp{local} was presented. You can use
+other prefixes to organize your aliases or disambiguate entries. You
+might use prefixes for locales, jobs, or activities. For example, I
+have:
-@vindex @code{mh-lpr-command-format}, example
+@smallexample
+@group

+@end smallexample
-@lisp
-(setq mh-lpr-command-format "nenscript -G -r -2 -i'%s'")
-@end lisp
+Using prefixes instead of postfixes helps you explore aliases during
+completion. If you forget the name of an old dive buddy, you can enter
+@samp{div} and then @key{SPC} to get a listing of all your dive buddies.
-@ref{Customizing Printing} talks more about this variable.
+@kindex M-x mh-alias-add-address-under-point

+
+These fields can only be added after the recipient is known. Because
+you can continue to add recipients as you edit the draft, MH-E waits
+until the message is sent to perform the auto-insertions. This seems
+strange at first, but you'll get used to it. There are two ways to
+help you feel that the desired fields are added. The first is the
+action when the message is sent: if any fields are added
+automatically, you are given a chance to see and to confirm these
+fields before the message is actually sent. You can do away with this
+confirmation by turning off the option
+@code{mh-auto-fields-prompt-flag}. The second method is manual: once
+the header contains one or more recipients, you may run the command
+@kbd{C-c M-d} (@code{mh-insert-auto-fields}) or choose the
+@samp{Identity -> Insert Auto Fields} menu item to insert these fields
+manually. However, if you use this command, the automatic insertion
+when the message is sent is disabled.
+
+@vindex mh-auto-fields-list
+@vindex mh-identity-list
+
+You should avoid using the same header field in
+@code{mh-auto-fields-list} and @code{mh-identity-list} definitions
+that may apply to the same message as the result is undefined.
+
+@vindex mh-identity-handlers
+@vindex mh-identity-list
+
+The option @code{mh-identity-handlers} is used to change the way that
+fields, signatures, and attributions in @code{mh-identity-list} are
+added. To customize @code{mh-identity-handlers}, replace the name of
+an existing handler function associated with the field you want to
+change with the name of a function you have written. You can also
+click on an @samp{INS} button and insert a field of your choice and
+the name of the function you have written to handle it.
+
+@vindex mh-identity-list
+
+The @samp{Field} field can be any field that you've used in your
+@code{mh-identity-list}. The special fields @samp{:attribution-verb},
+@samp{:signature}, or @samp{:pgg-default-user-id} are used for the
+@code{mh-identity-list} choices @samp{Attribution Verb},
+@samp{Signature}, and @samp{GPG Key ID} respectively.
+
+The handler associated with the @samp{:default} field is used when no
+other field matches.
+
+The handler functions are passed two or three arguments: the field
+itself (for example, @samp{From}), or one of the special fields (for
+example, @samp{:signature}), and the action @samp{'remove} or
+@samp{'add}. If the action is @samp{'add}, an additional argument
+containing the value for the field is given.

+Earlier, the command @kbd{F s} (@code{mh-search}) was introduced which
+helps you find messages that lie buried in your folders
+(@pxref{Folders}). This chapter covers this command in more detail.

-it cannot find the directories, or finds the wrong ones, you should set
-these variables. The name of the directory should be placed in double

-@vindex @code{mh-clean-message-header}

-@vindex @code{mh-visible-headers}
-
-Several variables control what displayed messages look like. Normally
-messages are delivered with a handful of uninteresting header fields.
-You can make them go away by setting @code{mh-clean-message-header} to a
-non-@code{nil} value. The header can then be cleaned up in two ways. By
-default, the header fields in @code{mh-invisible-headers} are removed.
-On the other hand, you could set @code{mh-visible-headers} to the fields
-that you would like to see. If this variable is set,
-@code{mh-invisible-headers} is ignored. I suggest that you not set
-@code{mh-visible-headers} since if you use this variable, you might miss
-a lot of header fields that you'd rather not miss. As an example of how
-to set a string variable, @code{mh-visible-headers} can be set to show a
-minimum set of header fields (see (@ref{Regexps, , Syntax of Regular
-Expressions, emacs, The GNU Emacs Manual}, for a description of the
-special characters in this string):

-(setq mh-visible-headers "^From: \\|^Subject: \\|^Date: ")
-@end lisp
-
-@cindex @code{mhl}
-@cindex MH commands, @code{mhl}
-@vindex @code{mhl-formfile}
-
-Normally mh-e takes care of displaying messages itself (rather than
-calling an MH program to do the work). If you'd rather have @code{mhl}
-display the message (within mh-e), set the variable @code{mhl-formfile}
-to a non-@code{nil} value. You can set this variable either to @code{t}
-to use the default format file or to a filename if you have your own
-format file (@code{mhl}(1) tells you how to write one). When writing
-your own format file, use a nonzero value for @code{overflowoffset} to
-ensure the header is RFC 822 compliant and parsable by mh-e.
-@code{mhl} is always used for printing and forwarding; in this case, the
-value of @code{mhl-formfile} is consulted if it is a filename.
-
-@vindex @code{mh-show-mode-hook}
-
-Two hooks can be used to control how messages are displayed. The first
-hook, @code{mh-show-mode-hook}, is called early on in the process of
-displaying of messages. It is used to perform some actions on the
-contents of messages, such as highlighting the header fields. If you're
-running Emacs 19 under the X Window System, the following example will
-highlight the @samp{From:} and @samp{Subject:} header fields. This is a
-very nice feature indeed.

+If you find that you do the same thing over and over when editing the

+To perform the search, type @kbd{C-c C-c} (@code{mh-index-do-search}).
+Sometimes you're searching for text that is either not indexed, or
+hasn't been indexed yet. In this case you can override the default
+method with the pick method by running the command @kbd{C-c C-p}
+(@code{mh-pick-do-search}).

+@vindex mh-search-folder
+
+The messages that are found are put in a temporary sub-folder of
+@samp{+mhe-index} and are displayed in an MH-Folder buffer. This
+buffer is special because it displays messages from multiple folders;
+each set of messages from a given folder has a heading with the folder
+name. The appearance of the heading can be modified by customizing the
+face @code{mh-search-folder}. You can jump back and forth between the
+headings using the commands @kbd{@key{TAB}}
+(@code{mh-index-next-folder}) and @kbd{S-@key{TAB}}
+(@code{mh-index-previous-folder}).
+
+@findex mh-index-visit-folder
+@findex mh-rescan-folder
+@kindex F r
+@kindex v
+
+In addition, the command @kbd{v} (@code{mh-index-visit-folder}) can be
+used to visit the folder of the message at point. Initially, only the
+messages that matched the search criteria are displayed in the folder.
+While the temporary buffer has its own set of message numbers, the
+actual messages numbers are shown in the visited folder. Thus, the
+command @kbd{v} is useful to find the actual message number of an
+interesting message, or to view surrounding messages with the command
+@kbd{F r} @code{mh-rescan-folder}. @xref{Folders}.

+Threading large number of messages can be time consuming so the option

+@kindex T o
+
+There are threaded equivalents for the commands that delete and refile
+messages. For example, @kbd{T o} (@code{mh-thread-refile}) refiles the
+current message and all its children. Similarly, the command @kbd{T d}
+(@code{mh-thread-delete}) deletes the current message and all its
+children. These commands do not refile or delete sibling messages.

+If you find that threading is too slow, it may be that you have
+@code{mh-large-folder} set too high. Also, threading is one of the few
+features of MH-E that really benefits from compiling. If you haven't
+compiled MH-E, I encourage you to do so@footnote{If you're not sure if
+MH-E has been byte-compiled, you could try running @samp{locate
+mh-thread.elc} or otherwise find MH-E on your system and ensure that
+@file{mh-thread.elc} exists. If you have multiple versions and you
+find that one is compiled but the other is not, then go into your

+MH-E depends on @uref{http://spamassassin.apache.org/, SpamAssassin},
+@uref{http://bogofilter.sourceforge.net/, bogofilter}, or
+@uref{http://spamprobe.sourceforge.net/, SpamProbe} to throw the dreck
+away. This chapter describes briefly how to configure these programs
+to work well with MH-E and how to use MH-E's interface that provides
+continuing education for these programs.
+
+@vindex mh-junk-program
+
+The default setting of the option @code{mh-junk-program} is
+@samp{Auto-detect} which means that MH-E will automatically choose one
+of SpamAssassin, bogofilter, or SpamProbe in that order. If, for
+example, you have both SpamAssassin and bogofilter installed and you
+want to use bogofilter, then you can set this option to
+@samp{Bogofilter}.
+
+@findex mh-junk-blacklist
+@kindex J b
+@vindex mh-junk-disposition
+
+The command @kbd{J b} (@code{mh-junk-blacklist}) trains the spam
+program in use with the content of the range (@pxref{Ranges}) and then
+handles the message(s) as specified by the option
+@code{mh-junk-disposition}. By default, this option is set to
+@samp{Delete Spam} but you can also specify the name of the folder
+which is useful for building a corpus of spam for training purposes.
+
+@findex mh-junk-whitelist
+@kindex J w
+
+In contrast, the command @kbd{J w} (@code{mh-junk-whitelist})
+reclassifies a range of messages (@pxref{Ranges}) as ham if it were
+incorrectly classified as spam. It then refiles the message into the
+@file{+inbox} folder.
+
+@cindex @samp{*MH-E Log*}

+By default, the programs are run in the foreground, but this can be
+slow when junking large numbers of messages. If you have enough memory
+or don't junk that many messages at the same time, you might try
+turning on the option @code{mh-junk-background}. @footnote{Note that
+the option @code{mh-junk-background} is used as the @code{display}
+argument in the call to @code{call-process}. Therefore, turning on
+this option means setting its value to @samp{0}. You can also set its
+value to @samp{t} to direct the programs' output to the @samp{*MH-E

-To control how much of the message to which you are replying is yanked
-by @kbd{C-c C-y} (@code{mh-yank-cur-msg}) into your reply, modify
-@code{mh-yank-from-start-of-msg}. The default value of @code{t} means
-that the entire message is copied. If it is set to @code{'body} (don't
-forget the apostrophe), then only the message body is copied. If it is
-set to @code{nil}, only the part of the message following point (the
-current cursor position in the message's buffer) is copied. In any
-case, this variable is ignored if a region is set in the message you are
-replying to. The string contained in @code{mh-ins-buf-prefix} is
-inserted before each line of a message that is inserted into a draft
-with @kbd{C-c C-y} (@code{mh-yank-cur-msg}). I suggest that you not
-modify this variable. The default value of @samp{"> "} is the default
-string for many mailers and news readers: messages are far easier to
-read if several included messages have all been indented by the same
-string. The variable @code{mail-citation-hook} is @code{nil} by
-default, which means that when a message is inserted into the letter,
-each line is prefixed by @code{mh-ins-buf-prefix}. Otherwise, it can be

+If you don't use @command{spamc}, use @samp{spamassassin -P -a}.
+
+Note that one of the recipes above throws away messages with a score
+greater than or equal to 10. Here's how you can determine a value that
+works best for you.
+
+First, run @samp{spamassassin -t} on every mail message in your
+archive and use @command{gnumeric} to verify that the average plus the
+standard deviation of good mail is under 5, the SpamAssassin default
+for ``spam''.
+
+Using @command{gnumeric}, sort the messages by score and view the
+messages with the highest score. Determine the score which encompasses
+all of your interesting messages and add a couple of points to be
+conservative. Add that many dots to the @samp{X-Spam-Level:} header
+field above to send messages with that score down the drain.
+
+In the example above, messages with a score of 5-9 are set aside in
+the @samp{+spam} folder for later review. The major weakness of
+rules-based filters is a plethora of false positives so it is
+worthwhile to check.
+
+@findex mh-junk-blacklist
+@findex mh-junk-whitelist
+@kindex J b
+@kindex J w
+
+If SpamAssassin classifies a message incorrectly, or is unsure, you can
+use the MH-E commands @kbd{J b} (@code{mh-junk-blacklist}) and
+@kbd{J w} (@code{mh-junk-whitelist}).
+
+@cindex @command{sa-learn}
+@cindex @file{.spamassassin/user_prefs}
+@cindex files, @file{.spamassassin/user_prefs}
+
+The command @kbd{J b} (@code{mh-junk-blacklist}) adds a
+@samp{blacklist_from} entry to @file{~/spamassassin/user_prefs},
+deletes the message, and sends the message to the Razor, so that
+others might not see this spam. If the @command{sa-learn} command is
+available, the message is also recategorized as spam.
+
+The command@kbd{J w} (@code{mh-junk-whitelist}) adds a
+@samp{whitelist_from} rule to @samp{~/.spamassassin/user_prefs}. If
+the @command{sa-learn} command is available, the message is also
+recategorized as ham.
+
+Over time, you'll observe that the same host or domain occurs
+repeatedly in the @samp{blacklist_from} entries, so you might think
+that you could avoid future spam by blacklisting all mail from a
+particular domain. The utility function
+@code{mh-spamassassin-identify-spammers} helps you do precisely that.
+This function displays a frequency count of the hosts and domains in
+the @samp{blacklist_from} entries from the last blank line in
+@file{~/.spamassassin/user_prefs} to the end of the file. This
+information can be used so that you can replace multiple
+@samp{blacklist_from} entries with a single wildcard entry such as:
-You can change the name of the file inserted with @kbd{C-c C-s}
-(@code{mh-insert-signature}) by changing @code{mh-signature-file-name}

+In versions of SpamAssassin (2.50 and on) that support a Bayesian

+@command{sa-learn} to recategorize the message as spam. Neither MH-E,

+@end vtable
+
+@vindex mh-adaptive-cmd-note-flag
+
+There are a couple of caveats when creating your own scan format file.
+First, MH-E will not work if your scan lines do not include message
+numbers. It will work poorly if you don't dedicate a column for
+showing the current message and notations. You won't be able to use
+the option @code{mh-adaptive-cmd-note-flag} or the threading features
+(@pxref{Threading}).
+
+@cindex message numbers
+@findex mh-set-cmd-note
+@vindex mh-adaptive-cmd-note-flag
+@vindex mh-scan-format-file
+
+If you've created your own format to handle long message numbers,
+you'll be pleased to know you no longer need it since MH-E adapts its
+internal format based upon the largest message number if
+@code{mh-adaptive-cmd-note-flag} is on (the default). If you prefer
+fixed-width message numbers, turn off @code{mh-adaptive-cmd-note-flag}
+and call @code{mh-set-cmd-note} with the width specified by your
+format file (see @code{mh-scan-format-file}). For example, the default
+width is 4, so you would use @samp{(mh-set-cmd-note 4)}.
+
+@vindex mh-adaptive-cmd-note-flag
+@vindex mh-scan-format-file
+@vindex mh-scan-format-mh
+@vindex mh-scan-format-nmh
+
+The default setting for @code{mh-scan-format-file} is @samp{Use MH-E
+scan Format}. This means that the format string will be taken from the
+either @code{mh-scan-format-mh} or @code{mh-scan-format-nmh} depending
+on whether MH or nmh (or GNU mailutils) is in use. This setting also
+enables you to turn on the option @code{mh-adaptive-cmd-note-flag}.
+You can also set this option to @samp{Use Default scan Format} to get
+the same output as you would get if you ran @command{scan} from the
+shell. If you have a format file that you want MH-E to use but not MH,
+you can set this option to @samp{Specify a scan Format File} and enter
+the name of your format file.
+
+@vindex mh-scan-format-file
+@vindex mh-scan-format-mh
+@vindex mh-scan-format-nmh
+
+The scan format that MH-E uses when @code{mh-scan-format-file} is set
+to its default of @samp{Use MH-E scan Format} is held in the variables
+@code{mh-scan-format-nmh} and @code{mh-scan-format-mh} depending on
+whether you are using nmh (or GNU mailutils) or not. Typically, you
+create your own format files rather than modifying these variables.
+The value of @code{mh-scan-format-nmh} is:
-@cindex using folders
-@vindex @code{mh-recursive-folders}
-@vindex @code{mh-auto-folder-collect}
-
-By default, operations on folders work only one level at a time. Set
-@code{mh-recursive-folders} to non-@code{nil} to operate on all folders.
-This mostly means that you'll be able to see all your folders when you
-press @key{TAB} when prompted for a folder name. The variable
-@code{mh-auto-folder-collect} is normally turned on to generate a list
-of folder names in the background as soon as mh-e is loaded. Otherwise,
-the list is generated when you need a folder name the first time (as
-with @kbd{o} (@code{mh-refile-msg})). If you have a lot of folders and
-you have @code{mh-recursive-folders} set, this could take a while, which
-is why it's nice to do the folder collection in the background.

-The function @code{mh-default-folder-for-message-function} is used by
-@kbd{o} (@code{mh-refile-msg}) and @kbd{C-c C-f C-f} (@code{mh-to-fcc})
-to generate a default folder. The generated folder name should be a
-string with a @samp{+} before it. For each of my correspondents, I use the
-same name for both an alias and a folder. So, I wrote a function that
-takes the address in the @samp{From:} header field, finds it in my alias
-file, and returns the alias, which is used as a default folder name.
-This is the most complicated example given here, and it demonstrates
-several features of Emacs Lisp programming. You should be able to drop
-this into @file{~/.emacs}, however. If you use this to store messages
-in a subfolder of your Mail directory, you can modify the line that
-starts @samp{(format +%s...} and insert your subfolder after the folder
-symbol @samp{+}.
-@c Note for me: if I insert a new version, don't forget to remove the
-@c "a/" from the folder name.

+
+The setting for @code{mh-scan-format-mh} is similar, except that MH
+doesn't have the function @code{decode} (which is used to decode RFC
+2047 encodings).
+
+@cindex notations, scan line
+@cindex scan line notations
+
+These strings are passed to the @command{scan} program via the
+@option{-format} argument. The formats are identical to the defaults
+except that additional hints for fontification have been added to the
+existing notations in the fifth column (remember that in Emacs, the
+columns start at 0). The values of the fifth column, in priority
+order, are: @samp{-} if the message has been replied to, @samp{t} if
+an address in the @samp{To:} field matches one of the mailboxes of the
+current user, @samp{c} if the @samp{Cc:} field matches, @samp{b} if
+the @samp{Bcc:} field matches, and @samp{n} if a non-empty
+@samp{Newsgroups:} field is present.
+
+@cindex @command{scan}
+@cindex MH commands, @command{scan}
+@vindex mh-progs
+@vindex mh-scan-prog
+
+The name of the program that generates a listing of one line per
+message is held in @code{mh-scan-prog} (default: @code{"scan"}).
+Unless this variable contains an absolute pathname, it is assumed to
+be in the @code{mh-progs} directory (@pxref{Getting Started}). You may
+link another program to @command{scan} (see @samp{mh-profile}(5)) to
+produce a different type of listing@footnote{See the section
+@uref{@value{MH-BOOK-HOME}/faswsprs.html, Find and Specify with scan
+pick Ranges Sequences} in the MH book.}.
+
+@cindex regular expressions, scan line formats
+@findex mh-set-cmd-note
+@findex setq
+
+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 @kbd{M-x apropos @key{RET}
+mh-scan.*regexp @key{RET}} to obtain a list of these variables. You
+will also have to call @code{mh-set-cmd-note} if your notations are
+not in column 4 (columns in Emacs start with 0). Note that unlike most
+of the user options described in this manual, these are variables and
+must be set with @code{setq} instead of in a customization buffer. For
+help with regular expressions, see
+@ifnothtml
+@ref{Regexps, , Syntax of Regular Expressions, emacs, The

+This regular expression matches messages sent to us. Note that the

+first should match the fontification hint (see
+@code{mh-scan-format-nmh}) and the second should match the user name
+as in the default of
+@w{@code{"^ *[0-9]+.\\([bct]\\).....[ ]*\\(..................\\)"}}.
+If this regular expression is not correct, the notation hints will not
+be highlighted with the face @code{mh-mh-folder-sent-to-me-hint} and

+This regular expression matches the subject. It must match from the
+beginning of the line. Note that the default setting of
+@samp{mh-folder-font-lock-keywords} expects this expression to contain
+at least three parenthesized expressions. The first is expected to
+match the @samp{Re:} string, if any, and is highlighted with the face
+@code{mh-folder-followup}. The second matches an optional bracketed
+number after @samp{Re:}, such as in @samp{Re[2]:} (and is thus a
+sub-expression of the first expression). The third is expected to
+match the subject line itself which is highlighted with the face
+@code{mh-folder-subject}. For example, the default is
+@w{@code{"^ *[0-9]+........[ ]*...................}}@*
+@w{@code{\\([Rr][Ee]\\(\\[[0-9]+\\]\\)?:\\s-*\\)*\\([^<\n]*\\)"}}.
+This regular expression should be correct as it is needed by

+two lines for readability, but is actually a single string.

-could perform some query and abort the quit or call
-@code{mh-execute-commands}, for example. The latter is not run in an

+Now view your new messages with the speedbar (@pxref{Speedbar}) or with
+@kbd{F n} (@code{mh-index-new-messages}). @xref{Folders}.
+
+If you're on a mailing list that is so voluminous that it is
+impossible to read every message, it usually better to read the
+mailing list like a newsgroup in a news reader. Emacs has a built-in
+newsreader called Gnus. The remainder of this appendix talks about how
+to use Gnus with an MH message store. The version of Gnus that was
+used to prepare this manual was 5.10. Versions 5.8 through 5.10 should
+work but versions prior to 5.8 use different options.
+
+This table contains a list of Gnus options that you will have to
+modify. Note that for them to become accessible, you'll have to load
+@file{nnml.el} first. This can be done with @kbd{M-x load-library
+@key{RET} nnml @key{RET}}.
+
+@vtable @code
+@item gnus-secondary-select-methods
+Select the @samp{nnml} value. This select method uses directories for
+folders and individual files for messages, just like MH. You do not
+have to set an address.
+@c -------------------------
+@item mail-sources
+Select the @samp{Several files in a directory} value, check the
+@samp{Path} box and enter @file{~/Mail} to tell Gnus where to find
+your mail.
+@c -------------------------
+@vindex mail-user-agent
+@item message-mail-user-agent
+In order to send mail within Gnus using MH-E, set this option to
+@samp{mail-user-agent} and set the @code{mail-user-agent} option to
+@samp{Emacs interface to MH}.
+@c -------------------------
+@item nnmail-keep-last-article
+Since Gnus keeps track of which messages you have read, it would be
+bad if Gnus expired the last message, for example, message 100, and
+@command{rcvstore} gave the next new message number 1. Gnus would then
+ignore it since it thinks that you've read messages 1-100. Turning on
+this option ensures that the last message is never removed thereby
+eliminating this problem.
+@end vtable
+
+Next add the following to @file{~/.procmailrc}. If you don't subscribe

One day in 1983 I got the flu and had to stay home from work for three
-days with nothing to do. I used that time to write MHE@. The
-fundamental idea behind MHE was that it was a ``puppeteer'' driving the MH
-programs underneath it. MH had a model that the editor was supposed to
-run as a subprocess of the mailer, which seemed to me at the time to be
-the tail wagging the dog. So I turned it around and made the editor
-drive the MH programs. I made sure that the UCI people (who were
-maintaining MH at the time) took in my changes and made them stick.
-
-Today, I still use my own version of MHE because I don't at all like the
-way that GNU mh-e works and I've never gotten to be good enough at
-hacking Emacs Lisp to make GNU mh-e do what I want. The Gosling-emacs

In 1987 I went to work for Bolt Beranek and Newman, as Jim had before

-stuck with it because I wanted the GNU Emacs interface. I am very
+me. In my previous job, I had been using RMAIL, but as my folders tend

+stuck with it because I wanted the GNU Emacs interface. I am very
familiar and comfortable with the Emacs interface (with just a few
modifications of my own) and dislike having to use applications with
embedded editors; they never live up to Emacs.
-MH is the mail reader of choice at BBN, so I converted to it. Since I
-didn't want to give up using an Emacs interface, I started using mh-e.
-As is my wont, I started hacking on it almost immediately. I first used
-version 3.4m. One of the first features I added was to treat the folder
-buffer as a file-visiting buffer: you could lock it, save it, and be
-warned of unsaved changes when killing it. I also worked to bring its
-functionality a little closer to RMAIL@. Jim Larus was very cooperative
-about merging in my changes, and my efforts first appeared in version
-3.6, distributed with Emacs 18.52 in 1988. Next I decided mh-e was too
-slow and optimized it a lot. Version, 3.7, distributed with Emacs 18.56
-in 1990, was noticeably faster.
-
-When I moved to the X Consortium I became the first person there to not
-use xmh. (There is now one other engineer there using mh-e.) About
-this point I took over maintenance of mh-e from Jim and was finally able
-to add some features Jim hadn't accepted, such as the backward searching
-undo. My first release was 3.8 (Emacs 18.58) in 1992.

+
+After a long break, Stephen handed the reins over to me in 2000. I
+moved the project to a new site called SourceForge and organized a
+great team of developers. Our first release in late 2001 was version
+6. It appeared around the time of Emacs 21.2 and had menus and tool
+bar buttons.
+
+Then, indexed searches, improved MIME handling, a speedbar, multiple
+identities, alias completion, an index view of unseen messages, spam
+software support, Face and X-Image-URL header field support, Fcc
+completion, arbitrary range handling, and draft form editing were
+introduced in the version 7 series around the time of Emacs 21.4
+(2004). Still, Emacs itself contained version 5 of MH-E released back
+in 1994.
+
+Version 8 development was mostly driven by the rewrite of the manual.
+It also brought mailutils support, S/MIME support, picon support, and
+an improved interface for hiding header fields. The CVS repository was
+migrated from SourceForge to Savannah (only for those files that were
+already part of Emacs) and the software was completely reorganized to
+push back two decades of entropy. Version 8 will appear in Emacs 22.1,
+expected to be released in 2006.

+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document ``free'' in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.

+@sp 1
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The ``Document'', below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as ``you''. You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall subject
+(or to related matters) and contains nothing that could fall directly
+within that overall subject. (Thus, if the Document is in part a
+textbook of mathematics, a Secondary Section may not explain any
+mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not ``Transparent'' is called ``Opaque.''
+
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML, PostScript or PDF designed for human modification. Examples of
+transparent image formats include PNG, XCF and JPG. Opaque formats
+include proprietary formats that can be read and edited only by
+proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML, PostScript or PDF produced by some word
+processors for output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a

+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this

+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+@sp 1
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+@sp 1
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+A. Use in the Title Page (and on the covers, if any) a title distinct
+ from that of the Document, and from those of previous versions
+ (which should, if there were any, be listed in the History section
+ of the Document). You may use the same title as a previous version
+ if the original publisher of that version gives permission.@*
+B. List on the Title Page, as authors, one or more persons or entities
+ responsible for authorship of the modifications in the Modified
+ Version, together with at least five of the principal authors of the
+ Document (all of its principal authors, if it has fewer than five),
+ unless they release you from this requirement.@*
+C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.@*
+D. Preserve all the copyright notices of the Document.@*
+E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.@*
+F. Include, immediately after the copyright notices, a license notice
+ giving the public permission to use the Modified Version under the
+ terms of this License, in the form shown in the Addendum below.@*
+G. Preserve in that license notice the full lists of Invariant Sections
+ and required Cover Texts given in the Document's license notice.@*
+H. Include an unaltered copy of this License.@*
+I. Preserve the section Entitled ``History'', Preserve its Title, and add
+ to it an item stating at least the title, year, new authors, and
+ publisher of the Modified Version as given on the Title Page. If
+ there is no section Entitled ``History'' in the Document, create one
+ stating the title, year, authors, and publisher of the Document as
+ given on its Title Page, then add an item describing the Modified
+ Version as stated in the previous sentence.@*
+J. Preserve the network location, if any, given in the Document for
+ public access to a Transparent copy of the Document, and likewise
+ the network locations given in the Document for previous versions
+ it was based on. These may be placed in the ``History'' section.
+ You may omit a network location for a work that was published at
+ least four years before the Document itself, or if the original
+ publisher of the version it refers to gives permission.@*
+K. For any section Entitled ``Acknowledgements'' or ``Dedications'',
+ Preserve the Title of the section, and preserve in the section all
+ the substance and tone of each of the contributor acknowledgements
+ and/or dedications given therein.@*
+L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section titles.@*
+M. Delete any section Entitled ``Endorsements.'' Such a section
+ may not be included in the Modified Version.@*
+N. Do not retitle any existing section to be Entitled ``Endorsements''
+ or to conflict in title with any Invariant Section.@*
+O. Preserve any Warranty Disclaimers.@*
+@sp 1
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+@sp 1
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications.'' You must delete all sections
+Entitled ``Endorsements.''
+@sp 1
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+@sp 1
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+@sp 1
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+@sp 1
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License. Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License. However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.
+@sp 1
+@item
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+http://www.gnu.org/copyleft/.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.

+@unnumberedsec ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+@smallexample
+@group
+Copyright (C) @var{year} @var{your name}.
+Permission is granted to copy, distribute and/or modify this document
+under the terms of the GNU Free Documentation License, Version 1.2
+or any later version published by the Free Software Foundation;
+with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
+A copy of the license is included in the section entitled ``GNU
+Free Documentation License''.
+@end group
+@end smallexample
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the ``with...Texts.'' line with this:
+
+@smallexample
+@group
+with the Invariant Sections being @var{list their titles}, with the
+Front-Cover Texts being @var{list}, and with the Back-Cover Texts being
+@var{list}.
+@end group
+@end smallexample
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.
