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