   #    Write a script in the user's home directory that can restore
   #    the permissions and ownerhips of all the files in the directory
   #    tree to their current ownerships and permissions.  This is done
   #    prior to making the user into an internally authenticated user
   #    in case they were previously file system authenticated and
   #    need to go back.
   #      The file we will create will be of the form
   #        restore_n.sh  Where n is a number that we will keep
   #   incrementing as needed until there isn't a file by that name.

   #    dir      - Path to the user's home directory.
