--
-- OBJECTIVE:
--      Check that separate subunits which share an ancestor may have the
--      same name if they have different fully qualified names.  Check
--      the case of separate subunits of separate subunits.
--      This test is a change in semantics from Ada 83 to Ada 9X.
--
-- TEST DESCRIPTION:
--      Declare a package that provides file processing operations.  Declare
--      one separate package to do the file processing, and another to do the
--      auditing.  These packages contain similar functions declared in 
--      separate subunits.  Verify that the main program can call the 
--      separate subunits with the same name.
--
--
-- CHANGE HISTORY:
--      06 Dec 94   SAIC    ACVC 2.0
--
--!

-- Simulates a file processing application.  The processing package opens
-- files, reads files, does file processing, and generates reports.
-- The auditing package opens files, read files, and generates reports.
