26 -- OBJECTIVE:
27 -- Check that entities and operations declared in a package can be used
28 -- in the private part of a child of a child of the package.
29 --
30 -- TEST DESCRIPTION:
31 -- Declare a series of library unit packages -- parent, child, and
32 -- grandchild. The grandchild package will have a private part.
33 -- From within the private part of the grandchild, make use of
34 -- components declared in the parent and grandparent packages.
35 --
36 -- TEST FILES:
37 -- The test consists of the following files:
