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