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=DIR      Install header files here.
                            Default; PREFIX/include

  
    stage                   Build and install only compiled library files
    =====                   to the stage directory.
                              
      --stagedir=DIR        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 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 Boost standard names
                                which include version number for Boost 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
                                Boost standard names, and does not install
                                includes to a versioned sub-directory. This
                                is intended for system integrators to build
                                for packaging of distributions.
