Boost provides free peer-reviewed portable C++ source libraries. A
  large part of Boost is provided as C++ template code which is
  resolved entirely at compile-time without linking. This package
  aims to provide the most useful subset of Boost libraries for
  template use among CRAN package. By placing these libraries in this
  package, we offer a more efficient distribution system for CRAN as
  replication of this code in the sources of other packages is avoided.
