-- This specification is adapted from the Ada Reference Manual for use with --
-- GNAT.  In accordance with the copyright of that document, you can freely --
-- copy and modify this specification,  provided that if you redistribute a --
-- modified version,  any changes that you have made are clearly indicated. --

   --  This unit is not implemented in typical GNAT implementations that
   --  lie on top of operating systems, because it is infeasible to implement
   --  in such environments. The RM anticipates this situation (RM D.11(10)),
   --  and permits an implementation to leave this unimplemented even if the

   --  Real-Time Systems annex is fully supported.
   --  If a target environment provides appropriate support for this package,
   --  then the Unimplemented_Unit pragma should be removed from this spec,
   --  and an appropriate body provided. The framework for such a body is

   --  included in the distributed sources.
