       cdrwtool -h

       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.

       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.

       -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.

       -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', '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'.

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

       -o offset
              Set write offset.
