ISOINFO(8)                                             ISOINFO(8)

       devdump,  isoinfo,  isovfy, isodump - Utility programs for
       dumping and verifying iso9660 images.
       isovfy is a utility to verify the integrity of an  iso9660
       image.  Most  of the tests in isovfy were added after bugs
       were discovered in early versions of  mkisofs.   It  isn't
       all  that clear how useful this is anymore, but it doesn't
       hurt to have this around.

These things are in the `mkisofs' package.
