# xcfview: a wrapper script that uses xcftools and an external viewer
# to display XCF images. The external viewer is found through the
# mailcap(5) database (q.v.) by using xdg-utils.
#
# Written by Henning Makholm <henning@makholm.net>
# Derived from the run-mailcap script by Brian White <bcwhite@pobox.com>
#
# In 2009 almost entirely rewritten by Jan Hauke Rahm <info@jhr-online.de>
# to make use of xdg-utils instead of parsing /etc/mailcap on its own
# That makes handling of dependencies *way* easier in Debian
#
# This script has been placed in the public domain (by both authors)
