| I've spent some time hunting bugs in UDF recently so I'll warn you a
| bit :). Definitely rewriting that ... code would be a good thing to do
| (reading that code I had urges to do it several times). The hard thing
| is that there is no reasonable spec you could use - there are two
| documents which define how UDF should look like but they are really hard
| to read (they have like hundred pages each and one does not make sence
| without the other). And reading the code and learning how the filesystem is
| supposed to work isn't too helpful either. Just a friendly warning ;)

I've that documants even printed ;) Actually they are _very-very_ big
indeed. I don't know may be just try to bring this code into Linux
codying style?
