- Rewrite the documentation in HTML
- Check out what's happening if you have a drive without compression
  and read compressed tapes (with decompression disabled)
- Improve on the user level applications so that they become useful
- Change the output format of 'dat' so that it is more useful

Improvements to 'st' driver:

- 'writes' to the 'st' driver should always go to EOT. If the tape is not
  at EOT the driver should first position at EOT. Only MTWEOF would go
  at the current position.
  Results in a much safer environment to people trying to append data to
  a dat.
