                        <p>Boost provides free peer-reviewed portable C++
                        source libraries.</p>

                        <p>We emphasize libraries that work well with the C++
                        Standard Library. Boost libraries are intended to be
                        widely useful, and usable across a broad spectrum of
                        applications. The <a href=
                        "more/license_info.html">Boost license</a> encourages
                        both commercial and non-commercial use.</p>

                        <p>We aim to establish &quot;existing practice&quot; and
                        provide reference implementations so that Boost
                        libraries are suitable for eventual standardization.
                        Ten Boost libraries are already included in the
                        <a href="http://www.open-std.org/jtc1/sc22/wg21">C++

                          This library does not itself implement the TR1 
                          components, rather it's a thin wrapper that will 
                          include your standard library's TR1 implementation 
                          (if it has one), otherwise it will include the Boost
                          Library equivalents, and import them into namespace 
                          <code>std::tr1</code>.  Highlights include: Reference Wrappers,
                          Smart Pointers, result_of, Function Object Binders,
