11   * A startup component for the Local Clients.
12 + * This class starts the CORBA client used for alerting
13 + * purposes.  It reads data using the ClientServant from CORBA
14 + * calls by the i-scream client interface.  This data is then
15 + * used by the MonitorManager to pass to Monitors.  Monitors then
16 + * analyse the data and raise alerts if needed, these are passed to
17 + * the Alerters, which send out alerts.  They are looked after by
18 + * the AlerterManager.
