26 -- FOUNDATION DESCRIPTION:
27 -- This foundation code is used to check visibility of separate
28 -- subunit of child packages.
29 -- Declares a package containing type definitions; package will be
30 -- with'ed by the root of the elevator abstraction.
31 --
32 -- Declare an elevator abstraction in a parent root package which manages
33 -- basic operations. This package has a private part. Declare a
34 -- private child package which calculates the floors for going up or
35 -- down. Declare a public child package which provides the actual
36 -- operations.
