**  Abstract:

 Shutdown a pre-existing, running DSI Daemon (see DSId::Server). From the command line 
 this utility is invoked with one (1) argument:

- The only argument is a small, (decimal) number enumerating a scope. For each scope there 
   exists one and only one DSId::Daemon. Therefore, from this argument the address of the 
   appropriate daemon is inferred. Valid scope numbers range from zero (0) to thirty-one (31). 
   This argument MUST be supplied. 
   
 Assuming one valid argument is provided, on success the utility shuts down the corresponding 
 daemon and on failure sends (to standard output) an appropriate error message.
