* This structure is used to control the output of fragments to the cdrom

* 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.
