DESCRIPTION

       The  cdwrtool  command can perform certain actions on a CD-R, CD-RW, or DVD-R device. Mainly these are blanking the media, formating it for
       use with the packet-cd device,  and applying an UDF filesystem.

       The most common usage is probably the `quick setup' option:

	      cdrwtool -d device -q

       which will blank the disc, format it as one large track, and write the UDF filesystem structures.

       Other options get and set various parameters of how the device is set up, and provide for different offsets, modes and  settings  from  the
       defaults.

       The usefulness of most of the options is not explained.

OPTIONS

       Main directives:

       -d device
	      Specify the device to use. eg. /dev/sr0

       -i     Print disc track info.

       -g     Print write parameters.

       -u length
	      Make a UDF filesystem using length number of blocks.

       -q     `Quick setup': blank the disc, format it as one large track and write a UDF filesystem.

       -m offset
	      Format the disc at offset number of blocks.

       -b mode
	      Blank the disk using a mode of `full' or `fast'.

       -f filename
	      Write file.

       -c track
	      Close track.

       -r track
	      Reserve track.

       -s     Set write parameters determined by -l, -w, and -p options for the disc.
	      (Note by your Debian maintainer: Apparently this option does nothing.)

       -v version
	      Specify the udf revision to use. Valid revisions are 0x0201, 0x0200, 0x0150, and 0x0102. If omitted, mkudffs udf-version is 0x0150.

       -h     Prints a sparse help message.

       Write parameters:

       -t speed
	      Set write speed. (Defaults to 12x ?)

       -l type
	      Set  multi-session field. Either `0' (default), `1', or `3', corresponding to `No B0 pointer. Next Session not allowed', `B0 pointer
	      = FF:FF:FF. Next session not allowed', and `Next session allowed. B0 pointer = next possible program area' respectively.

       -w mode
	      Set write mode. Either `mode1' or `mode2' (default).

       -p type
	      Set packet type. Either `0' or `1' (default), corresponding to variable and fixed packet sizes respectively.

       -o offset
	      Set write offset.
