[boost] Referencing Boost.Iostreams in the documentation of a non-boost library

Boost Experts, I am a fan of Boost.Iostreams and I am referencing them several times in the documentation of a little library that I wrote and posted on Google Code under "New BSD license" (https://code.google.com/p/async-ostream/). Do I need to provide a full URL or copyright information or anything else to make such reference to Boost.Iostreams legally sound? Or shall I just switch to use Boost Software License instead to keep it simple? Thanks! Gene
