+// This is the cpp11_shared_ptr_template_upcast runtime testcase. It checks that SWIG generates the appropriate, upcasted shared_ptr type for a template instantiation deriving from a base class.
+// In this case, the expected behavior is that given a cptr (underlying type shared_ptr<Printable<Derived> >), PrintableDerived_SWIGSmartPtrUpcast returns a cptr 
+// (underlying type std::shared_ptr< Derived >).
