For the person just starting with a Boost library, boost/library_name.hpp is the way to go (I wasn't suggesting not having that file). If that includes boost/library_name/all.hpp, then once boost/library_name.hpp exists, it will never change so library_name's developer need never worry about it again.
I wasn't commenting on the wisdom of boost/configurator/configurator.hpp, though I agree that the redundancy is unfortunate. However, if there's no other include file in boost/configurator, what name should it have?
