* Simple program to dump contents of iso9660 image in more usable format.
*
* Usage:
* To list contents of image (with or without RR):
* isoinfo -l [-R] -i imagefile
* To extract file from image:
* isoinfo -i imagefile -x xtractfile > outfile
* To generate a "find" like list of files:
* isoinfo -f -i imagefile
