# Usage:
#
#   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
#
#   link=static|shared      Whether to build static or shared libraries
#
#   threading=single|multi  Whether to build single or multithreaded binaries
#
#   runtime-link=static|shared
#                           Whether to link to static or shared C and C++
#                           runtime.
