"""
This script will unload clients that have not been accessed since the number
of weeks specified in the maintenance.cfg file.

This version of unload clients will delete clients with exclusive checkouts
since unload will not unload those clients.

It also deletes shelves from the clients to be deleted since delete will not
delete a client with a shelf.
