+--
+-- 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.
+--
