Boost

代码说明：

  C++标准库内容。在C++社区中影响甚大，是不折不扣的“准”标准库。Boost由于其对跨平台的强调，对标准C++的强调，与编写平台无关。(The content of the C++ standard library. A great influence in the C++ community, is hundred-percent quasi standard library. Boost because of its emphasis on cross platform, the emphasis on the standard of C++, and write platform independent.)
