/*************************************************************************

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.

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).
                      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.
