11// This is an overly complex test. The purpose of this test is to
12// demonstrate and test the ability to serialize a hierarchy of class
13// through a base class pointer even though those class might be
14// implemented in different dlls and use different extended type info
15// systems.
16//
17// polymorphic_ base is locally declared and defined. It use the
18// "no_rtti" extended type info system.
19
20// polymorphic_derived1 is locally declared and defined. It uses
21// the default "type_id" extended type info system
22
23// polymorphic_derived2 is declared in polymorphic_derived.hpp
24// and defined in dll_polymorphic_derived2. It uses the typeid
25// system.
