                        <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. One 
                           goal is to establish "existing practice" and provide reference implementations 
                           so that the Boost libraries are suitable for eventual standardization. Several 
                           Boost libraries will be included in the <a href="http://anubis.dkuug.dk/jtc1/sc22/wg21/">
                              C++ Standards Committee</a>'s upcoming <a href="http://std.dkuug.dk/jtc1/sc22/wg21/docs/library_technical_report.html">
                              C++ Standard Library Technical Report</a>.</p>
                        <p>Although Boost was begun by members of the C++ Standards Committee Library 
                           Working Group, membership has expanded to include nearly two thousand 
                           programmers from the C++ community at large.</p>

                        <p>If you are interested in becoming a member of Boost, please do so by joining 
                           our main developers mailing list. Discussions include both technical and 
                           site-related issues, and members are encouraged to participate in formal 
                           reviews of proposed libraries. There is also a users mailing list.</p>

                              developed and will replace the individual licenses for most Boost libraries. 
                              The new license offers better legal protection for both users and developers, 
                              and should speed user's legal reviews of Boost libraries. Dave Abrahams led the 
                              Boost effort to develop better licensing. The legal team was led by <a href="http://cyber.law.harvard.edu/people/cabell/index.html">

                        <p>August 12, 2003 - <b>ALERT</b></p>
                        <p>
                        Significant problems were found in the 1.30.1 release, so it has been withdrawn 
                        from the website. These problems mostly take the form of missing files due to 
                        an error by the release manager in using CVS to tag the release. We expect to 
                        release Version 1.30.2 in a few days. Stay tuned.
                        <p>Until then, you may want to get the <code>RC_1_30_0</code> branch (which, with 
                           only very slight modification, will become version 1.30.2) from our <a href="more/getting_started.html#CVS">

                        <p>August 4, 2003 - Version 1.30.1 (bugfix release)</p>
                        <p>Fixes were made to the following libraries:</p>
                        <ul>
                           <li>
                              The <a href="libs/lambda/doc/index.html">Boost.Lambda</a>

                                 Fixed. Using MSVC++6 (SP5), calling the assign action with a string value on

                                 Fixed: using assign semantic action in a grammar with a multi_pass iterator 
                                 adaptor applied to an std::istream_iterator resulted in a failure to compile 
                                 under msvc 7.0.
                                 <li>

                                 Fixed: Most trailing space bug
                                 <li>
                                    Fixed: <code>chset&lt;&gt;::operator~(range&lt;&gt;)</code> bug, <code>operator&amp;(chset&lt;&gt;, 
                                       range&lt;&gt;)</code> bug, <code>operator&amp;(range&lt;&gt;, chset&lt;&gt;)</code>

                                 <li>

                                    Fixed: <code>access_node_d[]</code> and <code>access_match_d[]</code>
