Usage:
    bjam [options] [install|stage]

    * install               Installs to the configured location(s).
    * stage                 Stages the build products only to common stage
                            location.

Options:
    --help                  This message.
    
    -sTOOLS=<toolsets>      Indicates the tools to build with.
    
    --show-libraries        Displays the list of Hamigaki libraries that require
                            build and installation steps, then exit.

    --layout=<layout>       Determines what kind of build layout to use. This
                            allows one to control the naming of the resulting
                            libraries, and the locations of the installed
                            files. Default is 'versioned'. Possible values:
                            
                                versioned - Uses the Hamigaki standard names
                                which include version number for Hamigaki the
                                release and version and name of the
                                compiler as part of the library names. Also
                                installs the includes to a versioned
                                sub-directory.
                                
                                system - Builds an install without the
                                Hamigaki standard names, and does not install
                                includes to a versioned sub-directory. This
                                is intended for system integrators to build
                                for packaging of distributions.

Locations:
    --prefix=PREFIX         Install architecture independent files here.
                            Default; C:\\Hamigaki on Win32
                            Default; /usr/local on Unix. Linux, etc.
                            
    --exec-prefix=EPREFIX   Install architecture dependent files here.
                            Default; PREFIX
                            
    --libdir=DIR            Install libraries here.
                            Default; EPREFIX/lib
                            
    --includedir=DIR        Install source headers here.
                            Default; PREFIX/include
                            
    --builddir=DIR          Build in this location instead of building
                            within the distribution tree. Recommended!
                            
    --stagedir=DIR          When staging only, stage to the location.
                            Default; ./stage

Features:
    --with-<library>        Build, stage, or install the specified <library>
                            If used, the default becomes to only build
                            indicated libraries.
                            
    --without-<library>     Do not build, stage, or install the specified
                            <library>. By default all libraries attempt to
                            build.
                            
    --with-python-root[=PYTHON_ROOT]
                            Build Boost.Python libraries with the Python
                            devel packages located at PYTHON_ROOT.
                            Default PYTHON_ROOT; C:\\Python24 on Win32.
                            Default PYTHON_ROOT; /usr on Unix, Linux, Cygwin, etc.
                            
    --with-python-version[=2.4]
                            Build Boost.Python libraries with the Python
                            version indicated.
                            Default; 2.4.
                            
    --with-pydebug          Build Boost.Python libraries using the
                            Python debug runtime.
