// Setting the serialization properties of boost::property<> and
// boost::no_property to is_bitwise_serializable, object_serializable,
// track_never only when BOOST_GRAPH_USE_MPI is defined is dubious.
//
// This changes the serialization format of these classes, and hence
// of boost::adjacency_list, depending on whether BOOST_GRAPH_USE_MPI
// is defined.
//
// These serialization properties should probably be set in either case.
//
// Unfortunately, doing that now will change the serialization format
// of boost::adjacency_list in the non-MPI case, and could potentially
// break software that reads files serialized with an older release.
