/* Simple program to show using libiso9660 to get a file path
for a given LSN of an ISO-9660 image.
If a single argument is given, it is used as the LSN to search for.
Otherwise we use a built-in default value.
If a second argument is given, it is 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.
