+
+Cross-compiling on Windows
+==========================
+
+Starting with Python 2.6, distutils is capable of cross-compiling between 
+Windows platforms.  In practice, this means that with the correct tools 
+installed, you can use a 32bit version of Windows to create 64bit extensions
+and vice-versa.
+
+To build for an alternate platform, specify the :option:`--plat-name` option 
+to the build command.  Valid values are currently 'win32', 'win-amd64' and 
+'win-ia64'.  For example, on a 32bit version of Windows, you could execute::
+
+   python setup.py build --plat-name=win-amd64
+
+to build a 64bit version of your extension.  The Windows Installers also 
+support this option, so the command::
+
+   python setup.py build --plat-name=win-amd64 bdist_wininst
+
+would create a 64bit installation executable on your 32bit version of Windows.
+
+To cross-compile, you must download the Python source code and cross-compile 
+Python itself for the platform you are targetting - it is not possible from a
+binary installtion of Python (as the .lib etc file for other platforms are
+not included.)  In practice, this means the user of a 32 bit operating 
+system will need to use Visual Studio 2008 to open the 
+:file:`PCBuild/PCbuild.sln` solution in the Python source tree and build the 
+"x64" configuration of the 'pythoncore' project before cross-compiling 
+extensions is possible.
+
+Note that by default, Visual Studio 2008 does not install 64bit compilers or
+tools.  You may need to reexecute the Visual Studio setup process and select
+these tools (using Control Panel->[Add/Remove] Programs is a convenient way to
+check or modify your existing install.)

 PEP 3116: New I/O Library
 =====================================================
 
-XXX write this.
+Python's built-in file objects support a number of methods, but
+file-like objects don't necessarily support all of them.  Objects that
+imitate files usually support :meth:`read` and :meth:`write`, but they
+may not support :meth:`readline`.  Python 3.0 introduces a layered I/O
+library in the :mod:`io` module that separates buffering and
+text-handling features from the fundamental read and write operations.
+
+There are three levels of abstract base classes provided by
+the :mod:`io` module:
+
+* :class:`RawIOBase`: defines raw I/O operations: :meth:`read`,
+  :meth:`readinto`, 
+  :meth:`write`, :meth:`seek`, :meth:`tell`, :meth:`truncate`,
+  and :meth:`close`.
+  Most of the methods of this class will often map to a single system call.
+  There are also :meth:`readable`, :meth:`writable`, and :meth:`seekable`
+  methods for determining what operations a given object will allow.
+
+  Python 3.0 has concrete implementations of this class for files and
+  sockets, but Python 2.6 hasn't restructured its file and socket objects
+  in this way.
+
+  .. XXX should 2.6 register them in io.py?
+
+* :class:`BufferedIOBase`: is an abstract base class that 
+  buffers data in memory to reduce the number of 
+  system calls used, making I/O processing more efficient.
+  It supports all of the methods of :class:`RawIOBase`, 
+  and adds a :attr:`raw` attribute holding the underlying raw object.
+
+  There are four concrete classes implementing this ABC:
+  :class:`BufferedWriter` and 
+  :class:`BufferedReader` for objects that only support
+  writing or reading and don't support random access,
+  :class:`BufferedRandom` for objects that support the :meth:`seek` method
+  for random access,
+  and :class:`BufferedRWPair` for objects such as TTYs that have 
+  both read and write operations that act upon unconnected streams of data.
+
+* :class:`TextIOBase`: Provides functions for reading and writing
+  strings (remember, strings will be Unicode in Python 3.0),
+  and supporting universal newlines.  :class:`TextIOBase` defines 
+  the :meth:`readline` method and supports iteration upon 
+  objects.   
+
+  There are two concrete implementations.  :class:`TextIOWrapper`
+  wraps a buffered I/O object, supporting all of the methods for
+  text I/O and adding a :attr:`buffer` attribute for access 
+  to the underlying object.  :class:`StringIO` simply buffers
+  everything in memory without ever writing anything to disk.
+
+  (In current 2.6 alpha releases, :class:`io.StringIO` is implemented in
+  pure Python, so it's pretty slow.   You should therefore stick with the 
+  existing :mod:`StringIO` module or :mod:`cStringIO` for now.  At some 
+  point Python 3.0's :mod:`io` module will be rewritten into C for speed,
+  and perhaps the C implementation will be  backported to the 2.x releases.)
+
+  .. XXX check before final release: is io.py still written in Python?
+
+In Python 2.6, the underlying implementations haven't been
+restructured to build on top of the :mod:`io` module's classes.  The
+module is being provided to make it easier to write code that's 
+forward-compatible with 3.0, and to save developers the effort of writing
+their own implementations of buffering and text I/O.

 PEP 3127: Integer Literal Support and Syntax
 =====================================================
 
-XXX write this -- this section is currently just brief notes.
+Python 3.0 changes the syntax for octal (base-8) integer literals,
+which are now prefixed by "0o" or "0O" instead of a leading zero, and
+adds support for binary (base-2) integer literals, signalled by a "0b"
+or "0B" prefix.
 
-Python 3.0 changes the syntax for octal integer literals, and 
-adds supports for binary integers: 0o instad of 0,
-and 0b for binary.  Python 2.6 doesn't support this, but a bin()
-builtin was added.
+Python 2.6 doesn't drop support for a leading 0 signalling 
+an octal number, but it does add support for "0o" and "0b"::
 
-XXX changes to the hex/oct builtins
+    >>> 0o21, 2*8 + 1
+    (17, 17)
+    >>> 0b101111
+    47
 
+The :func:`oct` built-in still returns numbers 
+prefixed with a leading zero, and a new :func:`bin` 
+built-in returns the binary representation for a number::
 
-New bin() built-in returns the binary form of a number.
+    >>> oct(42)
+    '052'
+    >>> bin(173)
+    '0b10101101'
+
+The :func:`int` and :func:`long` built-ins will now accept the "0o"
+and "0b" prefixes when base-8 or base-2 are requested, or when the
+**base** argument is zero (meaning the base used is determined from
+the string):
+
+    >>> int ('0o52', 0)

+def find_unused_port(family=socket.AF_INET, socktype=socket.SOCK_STREAM):
+    """Returns an unused port that should be suitable for binding.  This is
+    achieved by creating a temporary socket with the same family and type as
+    the 'sock' parameter (default is AF_INET, SOCK_STREAM), and binding it to
+    the specified host address (defaults to 0.0.0.0) with the port set to 0,
+    eliciting an unused ephemeral port from the OS.  The temporary socket is
+    then closed and deleted, and the ephemeral port is returned.
+
+    Either this method or bind_port() should be used for any tests where a
+    server socket needs to be bound to a particular port for the duration of
+    the test.  Which one to use depends on whether the calling code is creating
+    a python socket, or if an unused port needs to be provided in a constructor
+    or passed to an external program (i.e. the -accept argument to openssl's
+    s_server mode).  Always prefer bind_port() over find_unused_port() where
+    possible.  Hard coded ports should *NEVER* be used.  As soon as a server
+    socket is bound to a hard coded port, the ability to run multiple instances
+    of the test simultaneously on the same host is compromised, which makes the
+    test a ticking time bomb in a buildbot environment. On Unix buildbots, this
+    may simply manifest as a failed test, which can be recovered from without
+    intervention in most cases, but on Windows, the entire python process can
+    completely and utterly wedge, requiring someone to log in to the buildbot
+    and manually kill the affected process.
+
+    (This is easy to reproduce on Windows, unfortunately, and can be traced to
+    the SO_REUSEADDR socket option having different semantics on Windows versus
+    Unix/Linux.  On Unix, you can't have two AF_INET SOCK_STREAM sockets bind,
+    listen and then accept connections on identical host/ports.  An EADDRINUSE
+    socket.error will be raised at some point (depending on the platform and
+    the order bind and listen were called on each socket).
+
+    However, on Windows, if SO_REUSEADDR is set on the sockets, no EADDRINUSE
+    will ever be raised when attempting to bind two identical host/ports. When
+    accept() is called on each socket, the second caller's process will steal
+    the port from the first caller, leaving them both in an awkwardly wedged
+    state where they'll no longer respond to any signals or graceful kills, and
+    must be forcibly killed via OpenProcess()/TerminateProcess().
+
+    The solution on Windows is to use the SO_EXCLUSIVEADDRUSE socket option
+    instead of SO_REUSEADDR, which effectively affords the same semantics as
+    SO_REUSEADDR on Unix.  Given the propensity of Unix developers in the Open
+    Source world compared to Windows ones, this is a common mistake.  A quick
+    look over OpenSSL's 0.9.8g source shows that they use SO_REUSEADDR when
+    openssl.exe is called with the 's_server' option, for example. See
+    http://bugs.python.org/issue2550 for more info.  The following site also
+    has a very thorough description about the implications of both REUSEADDR
+    and EXCLUSIVEADDRUSE on Windows:
+    http://msdn2.microsoft.com/en-us/library/ms740621(VS.85).aspx)
+
+    XXX: although this approach is a vast improvement on previous attempts to
+    elicit unused ports, it rests heavily on the assumption that the ephemeral
+    port returned to us by the OS won't immediately be dished back out to some
+    other process when we close and delete our temporary socket but before our
+    calling code has a chance to bind the returned port.  We can deal with this
+    issue if/when we come across it.

+Notice that you need to use the same compiler version that was used to build

+
+The simplest way to build this example is to use the distutils script
+'setup.py'.  To do this, simply execute:
+
+  % python setup.py install
+
+after everything builds and installs, you can test it:
+
+  % python -c "import example; example.foo()"
+  Hello, world
+
+See setup.py for more details.  alternatively, see below for instructions on 
+how to build inside the Visual Studio environment.

+Visual Studio Build Instructions
+================================
+
+These are instructions how to build an extension using Visual C++.  The
+instructions and project files have not been updated to the latest VC
+version.  In general, it is recommended you use the 'setup.py' instructions
+above.

+versions of VC to build Python extensions, but the sample VC project file
