  75. <p>The Boost web site provides free
  76. peer-reviewed portable C++ source libraries. The
  77. emphasis is on libraries which work well with
  78. the C++ Standard Library. One goal is to
  79. establish &quot;existing practice&quot; and provide
  80. reference implementations so that the Boost
  81. libraries are suitable for eventual
  82. standardization. Several Boost libraries will be
  83. included in the <a href="http://anubis.dkuug.dk/jtc1/sc22/wg21/">
  84. C++ Standards Committee</a>'s upcoming
  85. <a href="http://std.dkuug.dk/jtc1/sc22/wg21/docs/library_technical_report.html">C++ Standard Library Technical
  86. Report</a>.</p>
  87. <p>Although Boost was begun by members of the C++ Standards Committee Library
  88. Working Group, membership has expanded to include nearly two thousand
  89. programmers from the C++ community at large.</p>
  90. <h2><a name="Membership">Membership</a></h2>
  91. <p>If you are interested in becoming a member of Boost, please do so by joining our
  92. main developers mailing list. Discussions include both technical and
  93. site-related issues, and members are encouraged to participate in formal
  94. reviews of proposed libraries. There is also a users mailing list.</p>
  95. <p>Both the main Boost developers list and the users list are also accessible as <a href="more/mailing_lists.htm">

  198. <p>August 12, 2003 - <b>ALERT</b></p>
  199. <p>Significant problems were found in
  200. the 1.30.1 release, so it has been
  201. withdrawn from the website. These
  202. problems mostly take the form of
  203. missing files due to an error by the
  204. release manager in using CVS to tag
  205. the release. We expect to release
  206. Version 1.30.2 in a few days. Stay
  207. tuned.
  208. <p>Until then, you may want to get
  209. the <code>RC_1_30_0</code> branch
  210. (which, with only very slight
  211. modification, will become version
  212. 1.30.2) from our <a
  213. href="more/getting_started.html#CVS">CVS</a>
  214. repository or the <a
  215. href="more/getting_started.html#CVS">CVS
  216. mirror</a> at <a

  229. iterator adaptor applied to an std::istream_iterator resulted in a failure
