xorriso 0.4.8.pl00-1 (powerpc binary) in ubuntu maverick

 xorriso is a command line and dialog application, which creates, loads,
 manipulates and writes ISO 9660 filesystem images with Rock Ridge extensions.
 .
 It maps file objects from POSIX compliant filesystems into Rock Ridge enhanced
 ISO 9660 filesystems and allows session-wise manipulation of such
 filesystems. It can load the management information of existing ISO images
 and it writes the session results to optical media or to filesystem objects.
