-- Grant of Unlimited Rights
--
-- The Ada Conformity Assessment Authority (ACAA) holds unlimited
-- rights in the software and documentation contained herein. Unlimited
-- rights are the same as those granted by the U.S. Government for older
-- parts of the Ada Conformity Assessment Test Suite, and are defined
-- in DFAR 252.227-7013(a)(19). By making this public release, the ACAA
-- intends to confer upon all recipients unlimited rights equal to those
-- held by the ACAA. These rights include rights to use, duplicate,
-- release or disclose the released technical data and computer software
-- in whole or in part, in any manner and for any purpose whatsoever, and

--
-- Notice
--
-- The ACAA has created and maintains the Ada Conformity Assessment Test
-- Suite for the purpose of conformity assessments conducted in accordance
-- with the International Standard ISO/IEC 18009 - Ada: Conformity
-- assessment of a language processor. This test suite should not be used
-- to make claims of conformance unless used in accordance with
-- ISO/IEC 18009 and any applicable ACAA procedures.
--
--*
-- OBJECTIVE:
-- Check that the categorization aspects Pure and Preelaborate can
-- be specified by a constant in another package.
--
-- Check that the categorization aspects Pure and Preelaborate can
-- specified as False, in which case they have no effect.
--
-- TEST DESCRIPTION:
-- We imagine that a subsystem of related packages are all specified
-- Pure (resp. Preelaborate) via an external constant, which allows
-- their categorization to be changed as a group by changing the constant.
-- Further, we imagine that the categorization has been turned off
-- to add some debugging code (emulated in this test by package Report)
-- that doesn't have the appropriate categorization. (After the debugging
-- is completed, the debugging code would be removed or commented out,
-- and the flag changed to True to re-apply the categorization.)
--
-- We try two subsystems, one for Pure and one for Preelaborate.
--
-- Note that the test can act as a kind of B-Test by changing the
-- values of the constants Is_Pure and Is_Preelab to True; the
-- withs of Report in the packages should be rejected in that case.
--
-- CHANGE HISTORY:
-- 18 Feb 2015 RLB Created test.
--
--!
