[boost] Traits and Policies

Hi, I am new to this list and saw the messages related to traits and policies. I am an experienced C++ developer but have a limited knowledge of the STL and even less of boost - I've joined this list in an effort to become more familiar. I understand policy classes but am not very familiar with traits. Can someone recommend a link for me to follow so I can better understand what they are as well as when, why and how to use them. TIA.
