Description:

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. Some of
the libraries have already been proposed for inclusion in the C++ Standards
Committee's upcoming C++ Standard Library Technical Report.

Although Boost was begun by members of the C++ Standards Committee Library
Working Group, membership has expanded to include nearly two thousand members
of the C++ community at large.
