--
-- 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.
