-# The boost threading library can be built on top of different API's
-# Currently this is the win32 API and the pthreads API.
-# Pthread is native on unix variants.
-# To get pthread on windows you need the pthread win32 library
-# http://sourceware.org/pthreads-win32 which is available under LGPL.
-#
-# You need to provide the include path and lib path in the variables
-# PTW32_INCLUDE and PTW32_LIB respectively. You can specify these
-# paths in site-config.jam, user-config.jam or in the environment.
-# A new feature is provided to request a specific API:
-# <threadapi>win32 and <threadapi)pthread.
-#
-# The naming of the resulting libraries is mostly the same for the
-# variant native to the build platform, i.e.
-# boost_thread and the boost specific tagging.
-# For the library variant that is not native on the build platform
-# an additional tag is applied:
-# boost_thread_pthread for the pthread variant on windows, and
-# boost_thread_win32 for the win32 variant (likely when built on cygwin).
-#
-# To request the pthread variant on windows, from boost root you would
-# say e.g:
-# bjam msvc-8.0 --with-thread install threadapi=pthread

-                    Using as a <link linkend="thread.build.precompiled">precompiled</link> library, possibly
-                    with auto-linking, or for use from within an IDE.
-                </listitem>

-                    Use from a <link linkend="thread.build.bjam">&Boost.Build;</link> project.

-            <para>
-                Using the &Boost.Thread; library in precompiled form is the way to go if you want to
-                install the library to a standard place, from where your linker is able to resolve code
-                in binary form. You also will want this option if compile time is a concern. Multiple 
-                variants are available, for different toolsets and build variants (debug/release).
-                The library files are named <emphasis>{lead}boost_thread{build-specific-tags}.{extension}</emphasis>,
-                where the build-specific-tags indicate the toolset used to build the library, whether it's
-                a debug or release build, what version of &Boost; was used, etc.; and the lead and extension
-                are the appropriate extensions for a dynamic link library or static library for the platform
-                for which &Boost.Thread; is being built.
-            	For instance, a debug build of the dynamic library built for Win32 with VC++ 7.1 using Boost 1.34 would
-            	be named <emphasis>boost_thread-vc71-mt-gd-1_34.dll</emphasis>.
-                More information on this should be available from the &Boost.Build; documentation.

-                To create the libraries you need to open a command shell and change to the

-                Replace <emphasis>mytoolset</emphasis> with the name of your toolset, e.g. msvc-7.1 .
-                This will compile and put the libraries into the <emphasis>stage</emphasis> directory which is just below the
-                <emphasis>boost_root</emphasis> directory. &Boost.Build; by default will generate static and

-                it is not necessary to explicitly specify the name of the library to link against, it is sufficient
-                to specify the path of the stage directory. Typically this is true on Windows. For gcc you need 
-                to specify the exact library name (including all the tags). Please don't forget that threading
-                support must be turned on to be able to use the library. You should be able now to build your

-                Of course it is also possible to use the &Boost.Thread; library in source form.
-                First you need to specify the <emphasis>boost_root</emphasis>/boost directory as
-                a path where your compiler expects to find files to include. It is not easy

-                library though. You would also need to isolate every include file that the thread
-                library depends on. Next you need to copy the files from 
-                <emphasis>boost_root</emphasis>/libs/thread/src to your project and instruct your
-                build system to compile them together with your project. Please look into the

-                to find out which compiler options and defines you will need to get a clean compile.
-                Using the boost library in this way is the least recommended, and should only be
-                considered if avoiding dependency on &Boost.Build; is a requirement. Even if so
-                it might be a better option to use the library in it's precompiled form. 
-                Precompiled downloads are available from the boost consulting web site, or as

+//      Original version.
+//   4 May 04 GlassfordM
+//      Implement lock promotion and demotion.
+//      Add locked() and state() member functions for debugging
+//         (should these be made public?).
+//      Rename to improve consistency and eliminate abbreviations:
+//          Use "read" and "write" instead of "shared" and "exclusive".
+//          Change "rd" to "read", "wr" to "write", "rw" to "read_write".
+//      Add mutex_type typdef.
