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