	Hi all,

	i've just checked in the vastly revamped worm driver.  The API has
	been totally restructured, and the usage does now almost resemble the
	other SCSI drivers, with the minor exception that you are required to
	tell the driver about your intentions with respect to the CD-R you are
	about to burn.  There's a wormcontrol(8) utility (usr.sbin/wormcontrol)
	as well for this.

	The driver has by now only been tested on a heavily tweaked 2.0.5R
	system against a Plasmon RF4100 recorder.  However, note that this
	driver is based on some other recent changes in the SCSI code, so you
	would have a hard time backporting it to 2.1R.  Usage of -current is

	Fitting hooks for other burners should not be too difficult, but you
	would best do this only with a certain understanding of the SCSI
	command-level protocol, and with a SCSI reference manual for your
	drive.  Chances are good that HP or Philips drives could be easily
	cloned from the Plasmon part, since they are rather similar.  Other
	drives will certainly require more work.

	There are still a lot of bugs in it, and i consider the driver still
	highly experimental.  Suggestions and discussion about the archi-
	tecture are welcome.

	cheers, J"org
