This procedure is used from within the Runtime to send -- debug informations. -- This primitive is overloaded in System.Traces.Tasking and this package -- Send_Trace_Info calls Send_Trace, in System.Traces.Send, which is target -- dependent, to send the debug informations to a debugger, stream .. -- To add a new event, just add them to the Trace_T type, and write the -- corresponding Send_Trace_Info procedure.
