# Usage:
#
#   bjam [options] [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 Win32
#                           Default; /usr/local on Unix. Linux, etc.
#
#   --exec-prefix=<EPREFIX> Install architecture dependent files here.
#                           Default; <PREFIX>
#
#   --libdir=<DIR>          Install library files here.
#                           Default; <EPREFIX>/lib
#
#   --includedir=<HDRDIR>   Install header files here.
#                           Default; <PREFIX>/include
#
#   stage                   Build and install only compiled library files
#   =====                   to the stage directory.
#
#   --stagedir=<STAGEDIR>   Install library files here
#                           Default; ./stage
#
# Other Options:
#
#   --builddir=DIR          Build in this location instead of building
#                           within the distribution tree. Recommended!
#
#   --toolset=toolset       Indicates the toolset to build with.
#
#   --show-libraries        Displays the list of Boost libraries that require
#                           build and installation steps, then exit.
#
#   --layout=<layout>       Determines 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 (default) - Names of boost
#                               binaries include the Boost version
#                               number and the name and version of the
#                               compiler.  Boost headers are installed
#                               in a subdirectory of <HDRDIR> whose
#                               name contains the Boost version
#                               number.
#
#                               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 who
#                               are building distribution packages.
#
#   --buildid=ID            Adds the specified ID to the name of built
#                           libraries.  The default is to not add anything.
#
#   --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.
