  26 -- OBJECTIVE:
  27 --      Check that separate subunits which share an ancestor may have the
  28 --      same name if they have different fully qualified names.  Check
  29 --      the case of separate subunits of separate subunits.
  30 --      This test is a change in semantics from Ada 83 to Ada 9X.
  31 --
  32 -- TEST DESCRIPTION:
  33 --      Declare a package that provides file processing operations.  Declare
  34 --      one separate package to do the file processing, and another to do the
  35 --      auditing.  These packages contain similar functions declared in
  36 --      separate subunits.  Verify that the main program can call the
  37 --      separate subunits with the same name.

  44
  45 -- Simulates a file processing application.  The processing package opens
  46 -- files, reads files, does file processing, and generates reports.
  47 -- The auditing package opens files, read files, and generates reports.
