# A simple program to show using libiso9660 to list files in a directory of
# an ISO-9660 image.
#
# If a single argument is given, it is used as the ISO 9660 image to
# use in the listing. Otherwise a compiled-in default ISO 9660 image
# name (that comes with the libcdio distribution) will be used.
