UDF Filesystem version 0.9.0

If you encounter problems with reading UDF discs using this driver,
please report them to linux_udf@hootie.lvld.hp.com, which is the
developer's list.

Write support requires a block driver which supports writing. The current
scsi and ide cdrom drivers do not support writing.

-------------------------------------------------------------------------------
The following mount options are supported:

	gid=		Set the default group.
	umask=		Set the default umask.
	uid=		Set the default user.
	unhide		Show otherwise hidden files.
	undelete	Show deleted files in lists.
	strict		Set strict conformance (unused)

The remaining are for debugging and disaster recovery:

	bs=			Set the block size. (may not work unless 2048)
	novrs		Skip volume sequence recognition 

The following expect a offset from 0.

	session=	Set the CDROM session (default= last session)
	anchor=		Override standard anchor location. (default= 256)
	volume=		Override the VolumeDesc location. (unused)
	partition=	Override the PartitionDesc location. (unused)
	lastblock=	Set the last block of the filesystem/

The following expect a offset from the partition root.

	fileset=	Override the fileset block location. (unused)
	rootdir=	Override the root directory location. (unused)
				WARNING: overriding the rootdir to a non-directory may
					yield highly unpredictable results.
