+
+# 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
