+-- TEST OBJECTIVE:
+--      Check that an extended type can be derived in the specification of a
+--      generic package when the parent is an abstract type in a library
+--      package.
+--
+-- TEST DESCRIPTION:
+--      Extend an abstract type in the visible part of a generic package.
+--      Make all of the procedures which override abstract procedures
+--      available as part of the generic interface.  Instantiate the generic.
+--
+-- TEST FILES: 
+--      This test depends on the following foundation code:
+--
+--         F393B00.A  Package Alert_Foundation
+--
+--
+-- CHANGE HISTORY:
+--      06 Dec 94   SAIC    ACVC 2.0
+--      14 Oct 95   SAIC    Update and repair for ACVC 2.0.1
+--      27 Feb 97   PWB.CTA Add pragma Elaborate for C393B12_0.
