This utility is used to increase the ref count on inodes moved to
lost+found by the non-AFS fsck. The program needs to be run once 
for every volume located on the partition that was fsck'ed.
Procedure:
     cc -o fixit fixit.c
     cd /vicepx
     chmod 600 *
     foreach volid ( cat <list-of-vol-ids> )
       fixit lost+found $volid
       echo $volid
     end
     umount <dev>
     /etc/vfsck <dev>       <<<< AFS Version!

Non-AFS fsck causes inodes to be moved to lost+found, with names like
#<inode-no>. The volumes associated with these inodes will still be
available, until the #<inode-no> file is removed. This program simply
ups the ref count on the #<inode-no> files, so they're not returned
to the free list when the files are removed from lost+found
