                        <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>

                        have been changed to remove the "<code>.</code>" (dot) character and to fix some 
                        other naming inconsistencies. For example, <code>vc7.1</code> toolset was renamed 
                        to become <code>vc-7_1</code>. Please refer to the 
                        <a href="more/getting_started.html#Tools">Supported Toolsets</a> section 
                        of the installation guide for the complete list of the current toolset names. 
                        This change was made as a part of the effort to make the Boost distribution 
                        compatible with ISO 9660 level 2 requirements.</p>

                        It is known to contain no regressions against the previous reference release on the 
                        compilers and configurations tested. Please refer to the corresponding 
                        <a href="http://www.meta-comm.com/engineering/boost-regression/1_32_0/index.html">regression reports</a> to see how well your
                        compiler performs on the new Boost codebase.

                              a unified <a href="more/license_info.html">Boost Software License</a> has been

                              and should speed user's legal reviews of Boost libraries. Dave Abrahams led the

                        <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">

                                 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.
