Chris@16: // DEPRECATED in favor of adl_predestruct with deconstruct<T>().
Chris@16: // A simple framework for creating objects with predestructors.
Chris@16: // The objects must inherit from boost::signals2::predestructible, and
Chris@16: // have their lifetimes managed by
Chris@16: // boost::shared_ptr created with the boost::signals2::deconstruct_ptr()
Chris@16: // function.
