--
-- Grant of Unlimited Rights
--
-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained
-- unlimited rights in the software and documentation contained herein.
-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making
-- this public release, the Government intends to confer upon all
-- recipients unlimited rights equal to those held by the Government.
-- These rights include rights to use, duplicate, release or disclose the
-- released technical data and computer software in whole or in part, in
-- any manner and for any purpose whatsoever, and to have or permit others

--
-- DISCLAIMER

-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR

-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
-- Check that two library child units and/or subunits may have the same
-- simple names if they have distinct expanded names.
--
-- TEST DESCRIPTION:
-- Declare a package that provides some primitive functionality (minimal
-- terminal driver operations in this case). Add child packages to
-- expand the functionality for different but related contexts (different
-- terminal kinds). Add child packages, or subunits, to the children to
-- provide the same high level operation for each of the different
-- contexts (terminals). Since the operations are the same, at the leaf
-- level they are likely to have the same names.
--
-- The main program "with"s the child packages. Check that the
-- child units and subunits perform as expected.
