                  <p>The Boost web site provides free peer-reviewed portable
                  C++ source libraries. The emphasis is on libraries which
                  work well with the C++ Standard Library. The libraries are
                  intended to be widely useful, and are in regular use by
                  thousands of programmers across a broad spectrum of
                  applications.</p>

                  <p>A further goal is to establish "existing practice" and
                  provide reference implementations so that Boost libraries
                  are suitable for eventual standardization. Ten Boost
                  libraries will be included in the <a href=
                  "http://www.open-std.org/jtc1/sc22/wg21/">C++ Standards
                  Committee</a>'s upcoming <a href=
                  "http://open-std.org/jtc1/sc22/wg21/docs/library_technical_report.html">
                  C++ Standard Library Technical Report</a> as a step toward
                  becoming part of a future C++ Standard.</p>

                  <p>Although Boost was begun by members of the C++ Standards
                  Committee Library Working Group, participation has expanded
                  to include thousands of programmers from the C++ community
                  at large.</p>
