on [<modes>]notice [<serial#>] [-|^]<match> { <action> }

This hook is triggered whenever the client receives a NOTICE from another client.

This hook will not be thrown if a matching ON GENERAL_NOTICE hook is being used in silent mode. ON GENERAL_NOTICE and on NOTICE are mutually exclusive.

The client does not permit any automated messages to be sent in response to a NOTICE. Any attempt will result in an error. The whole point of this is to prevent loops between clients.
