--

-- 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.
