+--     F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained

+--*
+--
+-- OBJECTIVE:
+--      Check that an object of a controlled type is finalized when the
+--      enclosing master is complete.
+--      Check this for controlled types where the derived type has a
+--      discriminant.
+--      Check this for subprograms of abstract types derived from the
+--      types in Ada.Finalization.
+--
+--      Check that finalization of controlled objects is
+--      performed in the correct order.  In particular, check that if
+--      multiple objects of controlled types are declared immediately
+--      within the same declarative part then type are finalized in the
+--      reverse order of their creation.
+--
+-- TEST DESCRIPTION:
+--      This test checks these conditions for subprograms and
+--      block statements; both variables and constants of controlled
+--      types; cases of a controlled component of a record type, as
+--      well as an array with controlled components.
+--
+--      The base controlled types used for the test are defined
+--      with a character discriminant.  The initialize procedure for
+--      the types will record the order of creation in a globally
+--      accessible array, the finalize procedure for the types will call
+--      TCTouch with that tag character.  The test can then check that
+--      the order of finalization is indeed the reverse of the order of
+--      creation (assuming that the implementation calls Initialize in
+--      the order that the objects are created).
