-#  attachments   +A */.*
-#  attachments   +A image/jpeg
-#  unattachments +A */.*
-#
-# This leaves "attached" image/jpeg files on the allowed attachments
-# list. It does not remove all items, as you might expect, because the
-# second */.* is not a matching expression at this time.
-#
-# Remember: "unattachments" only undoes what "attachments" has done!
-# It does not trigger any matching on actual messages.
-
-# Qualify any MIME part with an "attachment" disposition, EXCEPT for
-# text/x-vcard and application/pgp parts. (PGP parts are already known
-# to mutt, and can be searched for with ~g, ~G, and ~k.)
-#
-# I've added x-pkcs7 to this, since it functions (for S/MIME)
-# analogously to PGP signature attachments. S/MIME isn't supported
-# in a stock mutt build, but we can still treat it specially here.

-# text/plain. (Why inline a text/plain part unless it's external to the
-# message flow?)
-
-attachments   +I text/plain
-
-
-# These two lines make Mutt qualify MIME containers.  (So, for example,
-# a message/rfc822 forward will count as an attachment.)  The first
-# line is unnecessary if you already have "attach-allow */.*", of
-# course.  These are off by default!  The MIME elements contained
-# within a message/* or multipart/* are still examined, even if the
-# containers themselves don't qualify.

-# SYNOPSIS
-#	mutt_bgrun viewer [viewer options] file
-#
-# DESCRIPTION
-#	Mutt invokes external attachment viewers by writing the
-#	attachment to a temporary file, executing the pipeline specified
-#	for that attachment type in the mailcap file, waiting for the
-#	pipeline to terminate, writing nulls over the temporary file,
-#	then deleting it.  This causes problems when using graphical
-#	viewers such as qvpview and acroread to view attachments. 
-#
-#	If qvpview, for example, is executed in the foreground, the mutt
-#	user interface is hung until qvpview exits, so the user can't do
-#	anything else with mutt until he or she finishes reading the
-#	attachment and exits qvpview.  This is especially annoying when
-#	a message contains several MS Office attachments--one would like
-#	to have them all open at once. 
-#
-#	If qvpview is executed in the background, it must be given
-#	enough time to completely read the file before returning control
-#	to mutt, since mutt will then obliterate the file.  Qvpview is
-#	so slow that this time can exceed 20 seconds, and the bound is
-#	unknown.  So this is again annoying. 
-#
-#	The solution provided here is to invoke the specified viewer
-#	from this script after first copying mutt's temporary file to
-#	another temporary file.  This script can then quickly return
-#	control to mutt while the viewer can take as much time as it
-#	needs to read and render the attachment. 
-#
-# EXAMPLE
-#	To use qvpview to view MS Office attachments from mutt, add the
-#	following lines to mutt's mailcap file.
-#
-#	application/msword;             mutt_bgrun qvpview %s
-#	application/vnd.ms-excel;       mutt_bgrun qvpview %s
-#	application/vnd.ms-powerpoint;  mutt_bgrun qvpview %s

-# Mutt_octet_view is derived from Dave Pearson's mutt.octet.filter
-# script (http://www.hagbard.demon.co.uk/archives/mutt.octet.filter).
-# Mutt.octet.filter was designed to convert octet-stream e-mail
-# attachments to text for use with mutt's auto_view feature.
-# Mutt_octet_view extends this capability to use different viewers from
-# mutt's attachment menu, including graphical viewers if X is available.
-#
-# To use mutt_octet_view, put the following lines in your mailcap file:
-#
-#   application/octet-stream; mutt_octet_view -x %s; test=RunningX
-#   application/octet-stream; mutt_octet_view -v %s
-#   application/octet-stream; mutt_octet_view %s; copiousoutput
-#
-# and the following line in your muttrc file:
-#
-#   auto_view application/octet-stream 
-#
-# Mutt_octet_view is not a viewer itself; it only selects external
-# viewers based on the attachments' file name suffixes (extensions).
-# In addition to any viewers, you will need a copy of the author's
-# mutt_bgrun script in order to run X viewers in the background.

-# The behavior of mutt_octet_view is governed primarily by the 'Show'

-# its arguments for a command that it can use to display File.  It
-# begins in the table column specified by the option argument -t (the
-# default), -v or -x, and searches to the left until it finds a command
-# (non-empty string), which it executes.  Commands in the right-most
-# column are executed in the background and are left to handle their own
-# output.  Commands  in the other two columns are executed in the
-# foreground and send their output to stdout.

-#!/bin/sh
-#
-# word2text - convert MS Word files to ASCII text
-#
-# SYNOPSIS
-#	word2text file
-#
-# DESCRIPTION
-#	Word2text uses wvHtml, w3m and some perl glue to convert the MS
-#	Word file specified by the argument to ASCII text on stdout.
-#
-#	wvHtml converts MS Word files to HTML, but is intended to be
-#	used with a graphical browser such as Netscape Navigator, so it
-#	converts certain graphical elements to image files and
-#	corresponding <img> tags that the browser can render.  Since
-#	this script uses a text based browser, it uses perl to eliminate
-#	these <img> tags.
-#
-#	Compared to Quick View Plus (qvpview), the rendering of MS Word
-#	documents done by word2text is usually more accurate.  Qvpview
-#	doesn't render unrecognized characters well, if at all.  It also
-#	renders numbered lists as bullet lists.
-#
-#	Compared to the plain text translations that some people include
-#	in their e-mail along with the original MS Word attachments, the
-#	rendering done by word2text is usually more readable:  vertical
-#	spacing between paragraphs and list items is better and the
-#	adjustment of text within paragraphs is better.
-#
-# BUGS
-#	wvHtml occasionally dumps core.
-#	With the wv-0.7.4 release, some unnumbered lists are rendered as
-#	numbered.
-#

-#	Gary A. Johnson

-#
-# REVISION HISTORY
-#	2003-05-31
-#		Between wv-0.5.42 and wv-0.7.4, wvHtml changed to insert
-#		a <p> tag between each <li> tag and the following text,
-#		causing the list-item text to start on the line
-#		following the list-item bullet or number.  A perl
-#		expression was added to this script to fix the problem.
-# 	2003-02-19
-#		The command-line arguments to wvHtml changed, requiring
-#		the output file name as well as the input file name.
-#		Therefore, '-' (stdout) was added to the command as the
-#		output file name.
