Having just included a bunch of mpl header without looking at the manual
once, I agree with that. And no I don't happen to have the names memorized
(!), I just thought... "I wonder if the #includes are logical enough that
they're called boost/mpl/and.hpp" so I tried it and it all worked first time

That said there may be a case to be made for splitting into sub-libraries -
we did that with Boost.Math to avoid confusion between a distribution called
X and a special function called X. Non-the-less I hope the divisions are
obvious enough that most people won't need to look at the manual.

So +1 for a mpl/type_traits style of organization from me too,

Completely biased yours, John.
