-- This package implements functions for traces when tasking is not involved
-- Warning : NO dependencies to tasking should be created here
-- This package and all its children are used to implement debug information
-- A new primitive, Send_Trace_Info (Id : Trace_T; 'data') is introduced.
-- Trace_T is an event identifier, 'data' are the information to pass
-- with the event. This procedure is used from within the Runtime to send
-- debug information.
-- 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 information 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. It may be required for some
-- target to modify Send_Trace (e.g. VxWorks).
-- To add a new target, just adapt System.Traces.Send as needed
