+/*************************************************************************
+
+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.
