   1 // DEPRECATED in favor of adl_postconstruct with deconstruct<T>().
   2 // A simple framework for creating objects with postconstructors.
   3 // The objects must inherit from boost::signals2::postconstructible, and
   4 // have their lifetimes managed by
   5 // boost::shared_ptr created with the boost::signals2::deconstruct_ptr()
   6 // function.
