Aaarrrgh! Jeff, Thanks for the pointer. I've finally gotten used to the fact that the Documentation link on the boost.org home page doesn't include (for some reason) the documentation hidden under libs/<library name>/doc/*. Now I see that to find out about serialization, I need to not only check the various serialization documentation pages, but the library documentation to see that IT says about serialization. Anyway, that's good news. Thanks for the pointer. Merrill
