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

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_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).

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.
