/* Simple program to show using libiso9660 to list files in a directory of
   an ISO-9660 image and give some iso9660 information. See the code
   to iso-info for a more complete example.

   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.

   This program can be compiled with either a C or C++ compiler. In 
   the distributuion we perfer C++ just to make sure we haven't broken
   things on the C++ side.
