# Read a mail message on stdin and display X-Face, if one exists.
#
# See http://www.spinnaker.de/mutt/view-x-face for new versions.
#
# This is not the optimal way to implement X-Face support into a mailreader,
# but this works for me. I bound it to "ESC f" in my muttrc with the
# following command:
#  macro	pager	\ef	"|view-x-face\n"
#
# This script needs the following tools:
# uncompface from the compface package, which can be found at 
#	     ftp://ftp.cs.indiana.edu/pub/faces/compface/compface.tar.Z
# icontopbm  from the pbmplus or netpbm package, which you will find
#            everywhere on the net.
# A pbm viewer, e.g. xli, xv or if you don't have X11 running, you may want
#            to try out image2ascii, a little Shell script, which uses 
#            ImageMagick to convert nearly any graphics file to ASCII.
#            have a look at http://www.spinnaker.de/mutt/image2ascii
