Great!

I ask only that you update the documentation, to note that archive
authors should invoke BOOST_SERIALIZATION_DECLARE_ARCHIVE to make
their archives availabe to this mechanism, and to remove the warning
about header ordering.

You have two choices about how I'll handle backward compatibility:

1. Require that all user-written archive headers be updated with the
   next release of this library

2. Leave enough of the old mechanism in place so that existing code
   will still work as long as it follows the header ordering rule with
   respect to export.hpp

okay, maybe three choices:

3. Tell me that archive authors outside the library *already* have to
   invoke some macro that I don't know about, and I can add the effect
   of BOOST_SERIALIZATION_DECLARE_ARCHIVE to that macro's
   implementation.

Please let me know which of those angles I should pursue.
