  80 Volume ${volno} of the backup needs to be put in the tape drive.  Usually
  81 whoever prepared the backup leaves labeled tapes on top of the drive
  82 itself.  If there aren't any more, information about where to find tapes
  83 and how to label them are posted on the wall by apple-gunkies (unhelpfully
  84 obscured by a bookshelf).  An online copy (which is probably more
  85 up-to-date) can also be found in ~friedman/etc/fsf/backup.how.
