-- Grant of Unlimited Rights

-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained
-- unlimited rights in the software and documentation contained herein.
-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making
-- this public release, the Government intends to confer upon all
-- recipients unlimited rights equal to those held by the Government.
-- These rights include rights to use, duplicate, release or disclose the

--
-- OBJECTIVE:
-- Check that the types, operations, and other entities defined within
-- the package Ada.Strings.Maps are available and/or produce correct
-- results.
--
-- TEST DESCRIPTION:
-- This test demonstrates the availability and function of the types and
-- operations defined in package Ada.Strings.Maps. It demonstrates the
-- use of these types and functions as they would be used in common
-- programming practice.
-- Character set creation, assignment, and comparison are evaluated
-- in this test. Each of the functions provided in package
-- Ada.Strings.Maps is utilized in creating or manipulating set objects,
-- and the function results are evaluated for correctness.
-- Character sequences are examined using the functions provided for
-- manipulating objects of this type. Likewise, character maps are
-- created, and their contents evaluated. Exception raising conditions
-- from the function To_Mapping are also created.
-- Note: Throughout this test, the set logical operators are printed in
-- capital letters to enhance their visibility.
