 * This structure is used to control the output of fragments to the cdrom
 * image.  Everything that will be written to the output image will eventually
 * go through this structure.   There are two pieces - first is the sizing where
 * we establish extent numbers for everything, and the second is when we actually
 * generate the contents and write it to the output image.
 *
 * This makes it trivial to extend mkisofs to write special things in the image.
 * All you need to do is hook an additional structure in the list, and the rest
 * works like magic.
 *
 * The three passes each do the following:
 *
 * The 'size' pass determines the size of each component and assigns the extent number
 * for that component.
 *
 * The 'generate' pass will adjust the contents and pointers as required now that extent
 * numbers are assigned.  In some cases, the contents of the record are also generated.
 *
 * The 'write' pass actually writes the data to the disc.
