  11 This utility is used to increase the ref count on inodes moved to
  12 lost+found by the non-AFS fsck. The program needs to be run once
  13 for every volume located on the partition that was fsck'ed.
  14 Procedure:
  15      cc -o fixit fixit.c
  16      cd /vicepx
  17      chmod 600 *
  18      foreach volid ( cat <list-of-vol-ids> )
  19        fixit lost+found $volid
  20        echo $volid
  21      end
  22      umount <dev>
  23      /etc/vfsck <dev>       <<<< AFS Version!
  24
  25 Non-AFS fsck causes inodes to be moved to lost+found, with names like
  26 #<inode-no>. The volumes associated with these inodes will still be
  27 available, until the #<inode-no> file is removed. This program simply
  28 ups the ref count on the #<inode-no> files, so they're not returned
  29 to the free list when the files are removed from lost+found
