That is almost true.  Unfortunately, there are two problems (both of which
are not the fault of mt :-):

 (1)  Since there is no erase command defined in mtio.h, Gnu mt doesn't provide
      an erase function.  Has anyone added the erase command to Julian's SCSI
      drivers?  If not, I'll do it, but that might take a long time ...

 (2)  The no-rewind devices don't work correctly. thus making it hard to fsf
      etc.  I have a Wangtek 5150ES, and I get mysterious "error 0" messages
      on every *other* read attempt.   Like so:

	Tape conains:

	tar file 1
	<filemark>
	tar file 2
	<filemark>
	tar file 3
	<end of tape>

      When I say tar tvf /dev/nrst0, I get

      1.   tar file 1
      2.   error 0
      3.   tar file 2
      4.   error 0
      5.   tar file 3
      6.   read error

:-(
