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 +# +# AUTHOR +# Gary A.
