+# 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.
