+UDF Filesystem version 0.9.8.1
+
+If you encounter problems with reading UDF discs using this driver,
+please report them to linux_udf@hpesjro.fc.hp.com, which is the
+developer's list.
+
+Write support requires a block driver which supports writing. Currently
+dvd+rw drives and media support true random sector writes, and so a udf
+filesystem on such devices can be directly mounted read/write. CD-RW
+media however, does not support this. Instead the media can be formatted
+for packet mode using the utility cdrwtool, then the pktcdvd driver can
+be bound to the underlying cd device to provide the required buffering
+and read-modify-write cycles to allow the filesystem random sector writes
+while providing the hardware with only full packet writes. While not
+required for dvd+rw media, use of the pktcdvd driver often enhances
+performance due to very poor read-modify-write support supplied internally
+by drive firmware.
+
+-------------------------------------------------------------------------------
+The following mount options are supported:
+
+ gid= Set the default group.
+ umask= Set the default umask.
+ mode= Set the default file permissions.
+ dmode= Set the default directory permissions.
+ uid= Set the default user.
+ bs= Set the block size.
+ unhide Show otherwise hidden files.
+ undelete Show deleted files in lists.
+ adinicb Embed data in the inode (default)
+ noadinicb Don't embed data in the inode
+ shortad Use short ad's
+ longad Use long ad's (default)
+ nostrict Unset strict conformance
+ iocharset= Set the NLS character set
+
+The uid= and gid= options need a bit more explaining. They will accept a
+decimal numeric value which will be used as the default ID for that mount.
+They will also accept the string "ignore" and "forget". For files on the disk
+that are owned by nobody ( -1 ), they will instead look as if they are owned
+by the default ID. The ignore option causes the default ID to override all
+IDs on the disk, not just -1. The forget option causes all IDs to be written
+to disk as -1, so when the media is later remounted, they will appear to be
+owned by whatever default ID it is mounted with at that time.
+
+For typical desktop use of removable media, you should set the ID to that
+of the interactively logged on user, and also specify both the forget and
+ignore options. This way the interactive user will always see the files
+on the disk as belonging to him.
+
+The remaining are for debugging and disaster recovery:
+
+ 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.
