+ This is a file system used on some CD-ROMs and DVDs. Since the
+ file system is supported by multiple operating systems and is more
+ compatible with standard unix file systems, it is also suitable for
+ removable USB disks. Say Y if you intend to mount DVD discs or CDRW's

+ disks. Please read <file:Documentation/filesystems/udf.txt>.
To compile this file system support as a module, choose M here: the
module will be called udf.
