title: Which boost libraries are heading for TR2?
body: <p>If found this quote at boost.org:</p>
  
  <blockquote>
    <p><a href="http://www.boost.org/users/" rel="noreferrer">More Boost libraries are in the pipeline for TR2</a></p>
  </blockquote>
  
  <p>It links to the <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2005/n1810.html" rel="noreferrer">TR2 call from proposals</a>.  But I can't seem to find any other information on which boost libraries are headed for TR2.</p>
  
  <p>I've seen a draft proposal for Boost.Asio, and I vaguely remember seeing something about Boost.System and Boost.Filesystem being proposed as well.</p>
  
  <ul>
  <li>Which boost libraries are headed for TR2?</li>
  <li>What else has been proposed for the TR2?</li>
  <li>Are there any good sources of information for this?</li>
  </ul>
  
  <p>I know everyone's really focused on C++0x right now, and don't expect to find a lot of official information.  But surely someone's documented something about the TR2.</p>
