  /*************************************************************************
  
  USAGE:
  ~~~~~~
  
  Before including this header you must define one or more of define the following macros:
  
  BOOST_LIB_NAME:           Required: A string containing the basename of the library,
                            for example boost_regex.
  BOOST_LIB_TOOLSET:        Optional: the base name of the toolset.
  BOOST_DYN_LINK:           Optional: when set link to dll rather than static library.
  BOOST_LIB_DIAGNOSTIC:     Optional: when set the header will print out the name
                            of the library selected (useful for debugging).
  BOOST_AUTO_LINK_NOMANGLE: Specifies that we should link to BOOST_LIB_NAME.lib,
                            rather than a mangled-name version.
  BOOST_AUTO_LINK_TAGGED:   Specifies that we link to libraries built with the --layout=tagged option.
                            This is essentially the same as the default name-mangled version, but without
                            the compiler name and version, or the Boost version.  Just the build options.
  
  These macros will be undef'ed at the end of the header, further this header
  has no include guards - so be sure to include it only once from your library!
  
  Algorithm:
  ~~~~~~~~~~
  
  Libraries for Borland and Microsoft compilers are automatically
  selected here, the name of the lib is selected according to the following
  formula:
  
  BOOST_LIB_PREFIX
     + BOOST_LIB_NAME
     + "_"
     + BOOST_LIB_TOOLSET
     + BOOST_LIB_THREAD_OPT
     + BOOST_LIB_RT_OPT
     "-"
     + BOOST_LIB_VERSION
  
  These are defined as:
  
  BOOST_LIB_PREFIX:     "lib" for static libraries otherwise "".
  
  BOOST_LIB_NAME:       The base name of the lib ( for example boost_regex).
  
  BOOST_LIB_TOOLSET:    The compiler toolset name (vc6, vc7, bcb5 etc).
  
  BOOST_LIB_THREAD_OPT: "-mt" for multithread builds, otherwise nothing.
  
  BOOST_LIB_RT_OPT:     A suffix that indicates the runtime library used,
                        contains one or more of the following letters after
                        a hiphen:
  
                        s      static runtime (dynamic if not present).
                        g      debug/diagnostic runtime (release if not present).
                        y      Python debug/diagnostic runtime (release if not present).
                        d      debug build (release if not present).
                        g      debug/diagnostic runtime (release if not present).
                        p      STLPort Build.
  
  BOOST_LIB_VERSION:    The Boost version, in the form x_y, for Boost version x.y.
