[Boost-users] Serialization of intrusive_ptr's?

Hey, quick question, what do I need to do to serialize intrusive_ptr's? I don't see anything in the serialization documentation to indicate that it supports it, does it? If not, is there an easy way? Or do I need to serialize the raw pointers and re-construct the intrusive_ptr's one by one? I'm storing intrusive_ptr's inside std container classes(map, list). Thanks, Jared
