+  *   DESCRIPTION: Automatic library inclusion for Borland/Microsoft compilers.
+  */
+
+/*************************************************************************
+
+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.

+// setups:
+// #define BOOST_NO_CONFIG
+
+// define this to make the config "optimistic"
+// about unknown compiler versions.  Normally
+// unknown compiler versions are assumed to have

+// setting this flag, causes the config to assume
+// that unknown compiler versions are fully conformant

+// #define BOOST_STRICT_CONFIG
+
+// define this to cause the config to halt compilation
+// with an #error if it encounters anything unknown --
+// either an unknown compiler version or an unknown

+// prefix/suffix headers that normally control things like struct 
+// packing and alignment. 
+// #define BOOST_DISABLE_ABI_HEADERS
+
+// BOOST_ABI_PREFIX: A prefix header to include in place of whatever

+// BOOST_ALL_DYN_LINK: Forces all libraries that have separate source, 
+// to be linked as dll's rather than static libraries on Microsoft Windows 
+// (this macro is used to turn on __declspec(dllimport) modifiers, so that 
+// the compiler knows which symbols to look for in a dll rather than in a 
+// static library).  Note that there may be some libraries that can only 
+// be statically linked (Boost.Test for example) and others which may only 
+// be dynamically linked (Boost.Threads for example), in these cases this
