-# Additional configuration variables used:
-#   1. PTW32_DIR and PTW32_LIB may be used on Win32 platforms to specify that
-#      a version of Boost.Threads should be built that uses the
-#      the pthreads-win32 library instead of the Win32 native threading APIs.
-#      This feature is mostly used for testing and it's generally recommended
-#      that you use the Win32 native threading libraries instead. 
-#
-#      PTW32_Dir should be set to the installation path of the
-#      pthreads-win32 library and PTW32_LIB should be set to the name of the 
-#      library variant to link against (see the pthreads-win32 documentation).
-#      Example: jam -sPTW32_DIR="c:\pthreads-win32" -sPTW32_LIB="pthreadVCE.lib"
-#      Alternately, environment variables having the names PTW32_DIR and PTW32_LIB
-#      can be set instead of passing these values on the command line.
-#
-#      In either case, libraries having the names boost_thread_ptw32<tags>.dll
-#      and libboost_thread_ptw32<tags>.lib will be built
-#      in addition to the usual boost_thread<tags>.dll and 
-#      libboost_thread<tags>.lib. Link with one of the ptw32 versions
-#      of the Boost.Threads libraries to use the version of Boost.Threads
-#      that is implemented using pthreads-win32 (you will need to #define
-#      BOOST_THREAD_NO_LIB or BOOST_ALL_NO_LIB to disable auto-linking
-#      if your platform supports auto-linking in order to prevent
-#      your build from attempting to link to two different versions of 
-#      the Boost.Threads library).
