Restoring a controller team

NOTE: Before running this script, re-install the controller. Otherwise an Error 404 condition
results and the controller is not restored. See
Because the scripts in this appendix cross page boundaries, be careful to avoid including the
page number when copying a script. Copying a script one page at a time can prevent inclusion
of page numbers.
