+--  This package provides subprogram implementations of stream attributes for
+--  the following types:
+--     Ada.String
+--     Ada.Wide_String
+--     Ada.Wide_Wide_String
+--
+--  The compiler will generate references to the subprograms in this package
+--  when expanding stream attributes for the above mentioned types. Example:
+--
+--     String'Output (Some_Stream, Some_String);
+--
+--  will be expanded into:
+--
+--     String_Output (Some_Stream, Some_String);
