/* Simple program to show using libiso9660 to extract a file from a
cue/bin CD-IMAGE.
If a single argument is given, it is used as the CUE file of a CD image
to use. Otherwise a compiled-in default 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 distribution we prefer C++ just to make sure we haven't broken
things on the C++ side.
