+#   b2 [options] [properties] [install|stage]
+#
+#   Builds and installs Boost.
+#
+# Targets and Related Options:
+#
+#   install                 Install headers and compiled library files to the
+#   =======                 configured locations (below).
+#
+#   --prefix=<PREFIX>       Install architecture independent files here.
+#                           Default: C:\Boost on Windows
+#                           Default: /usr/local on Unix, Linux, etc.
+#
+#   --exec-prefix=<EPREFIX> Install architecture dependent files here.
+#                           Default: <PREFIX>
+#
+#   --libdir=<LIBDIR>       Install library files here.
+#                           Default: <EPREFIX>/lib
+#
+#   --includedir=<HDRDIR>   Install header files here.
+#                           Default: <PREFIX>/include
+#
+#   --cmakedir=<CMAKEDIR>   Install CMake configuration files here.
+#                           Default: <LIBDIR>/cmake
+#
+#   --no-cmake-config       Do not install CMake configuration files.
+#
+#   stage                   Build and install only compiled library files to the
+#   =====                   stage directory.
+#
+#   --stagedir=<STAGEDIR>   Install library files here
+#                           Default: ./stage
+#
+# Other Options:
+#
+#   --build-type=<type>     Build the specified pre-defined set of variations of
+#                           the libraries. Note, that which variants get built
+#                           depends on what each library supports.
+#
+#                               -- minimal -- (default) Builds a minimal set of
+#                               variants. On Windows, these are static
+#                               multithreaded libraries in debug and release
+#                               modes, using shared runtime. On Linux, these are
+#                               static and shared multithreaded libraries in
+#                               release mode.
+#
+#                               -- complete -- Build all possible variations.
+#
+#   --build-dir=DIR         Build in this location instead of building within
+#                           the distribution tree. Recommended!
+#
+#   --show-libraries        Display the list of Boost libraries that require
+#                           build and installation steps, and then exit.
+#
+#   --layout=<layout>       Determine whether to choose library names and header
+#                           locations such that multiple versions of Boost or
+#                           multiple compilers can be used on the same system.
+#
+#                               -- versioned -- Names of boost binaries include
+#                               the Boost version number, name and version of
+#                               the compiler and encoded build properties. Boost
+#                               headers are installed in a subdirectory of
+#                               <HDRDIR> whose name contains the Boost version
+#                               number.
+#
+#                               -- tagged -- Names of boost binaries include the
+#                               encoded build properties such as variant and
+#                               threading, but do not including compiler name
+#                               and version, or Boost version. This option is
+#                               useful if you build several variants of Boost,
+#                               using the same compiler.
+#
+#                               -- system -- Binaries names do not include the
+#                               Boost version number or the name and version
+#                               number of the compiler. Boost headers are
+#                               installed directly into <HDRDIR>. This option is
+#                               intended for system integrators building
+#                               distribution packages.
+#
+#                           The default value is 'versioned' on Windows, and
+#                           'system' on Unix.
+#
+#   --buildid=ID            Add the specified ID to the name of built libraries.
+#                           The default is to not add anything.
+#
+#   --python-buildid=ID     Add the specified ID to the name of built libraries
+#                           that depend on Python. The default is to not add
+#                           anything. This ID is added in addition to --buildid.
+#
+#   --help                  This message.
+#
+#   --with-<library>        Build and install the specified <library>. If this
+#                           option is used, only libraries specified using this
+#                           option will be built.
+#
+#   --without-<library>     Do not build, stage, or install the specified
+#                           <library>. By default, all libraries are built.
+#
+# Properties:
+#
+#   toolset=toolset         Indicate the toolset to build with.
+#
+#   variant=debug|release   Select the build variant

+# Boost C++ Libraries
+
+The Boost project provides free peer-reviewed portable C++ source libraries.
+
+We emphasize libraries that work well with the C++ Standard Library. Boost
+libraries are intended to be widely useful, and usable across a broad spectrum
+of applications. The Boost license encourages both commercial and non-commercial use
+and does not require attribution for binary use. 
+
+The project website is www.boost.org, where you can obtain more information and
