@@ -37,150 +37,9 @@ There are two approaches to building extension modules on Windows, just as there
 are on Unix: use the :mod:`distutils` package to control the build process, or
 do things manually.  The distutils approach works well for most extensions;
 documentation on using :mod:`distutils` to build and package extension modules
-is available in :ref:`distutils-index`.  This section describes the manual
-approach to building Python extensions written in C or C++.
-
-To build extensions using these instructions, you need to have a copy of the
-Python sources of the same version as your installed Python. You will need
-Microsoft Visual C++ "Developer Studio"; project files are supplied for VC++
-version 7.1, but you can use older versions of VC++.  Notice that you should use
-the same version of VC++that was used to build Python itself. The example files
-described here are distributed with the Python sources in the
-:file:`PC\\example_nt\\` directory.
-
-#. **Copy the example files** ---  The :file:`example_nt` directory is a
-   subdirectory of the :file:`PC` directory, in order to keep all the PC-specific
-   files under the same directory in the source distribution.  However, the
-   :file:`example_nt` directory can't actually be used from this location.  You
-   first need to copy or move it up one level, so that :file:`example_nt` is a
-   sibling of the :file:`PC` and :file:`Include` directories.  Do all your work
-   from within this new location.
-
-#. **Open the project** ---  From VC++, use the :menuselection:`File --> Open
-   Solution` dialog (not :menuselection:`File --> Open`!).  Navigate to and select
-   the file :file:`example.sln`, in the *copy* of the :file:`example_nt` directory
-   you made above.  Click Open.
-
-#. **Build the example DLL** ---  In order to check that everything is set up
-   right, try building:
-
-#. Select a configuration.  This step is optional.  Choose
-   :menuselection:`Build --> Configuration Manager --> Active Solution Configuration`
-   and select either :guilabel:`Release`  or :guilabel:`Debug`.  If you skip this
-   step, VC++ will use the Debug configuration by default.
-
-#. Build the DLL.  Choose :menuselection:`Build --> Build Solution`.  This
-   creates all intermediate and result files in a subdirectory called either
-   :file:`Debug` or :file:`Release`, depending on which configuration you selected
-   in the preceding step.
-
-#. **Testing the debug-mode DLL** ---  Once the Debug build has succeeded, bring
-   up a DOS box, and change to the :file:`example_nt\\Debug` directory.  You should
-   now be able to repeat the following session (``C>`` is the DOS prompt, ``>>>``
-   is the Python prompt; note that build information and various debug output from
-   Python may not match this screen dump exactly)::
-
-      C>..\..\PCbuild\python_d
-      Adding parser accelerators ...
-      Done.
-      Python 2.2 (#28, Dec 19 2001, 23:26:37) [MSC 32 bit (Intel)] on win32
-      Type "copyright", "credits" or "license" for more information.
-      >>> import example
-      [4897 refs]
-      >>> example.foo()
-      Hello, world
-      [4903 refs]
-      >>>
-
-   Congratulations!  You've successfully built your first Python extension module.
-
-#. **Creating your own project** ---  Choose a name and create a directory for
-   it.  Copy your C sources into it.  Note that the module source file name does
-   not necessarily have to match the module name, but the name of the
-   initialization function should match the module name --- you can only import a
-   module :mod:`spam` if its initialization function is called :c:func:`initspam`,
-   and it should call :c:func:`Py_InitModule` with the string ``"spam"`` as its
-   first argument (use the minimal :file:`example.c` in this directory as a guide).
-   By convention, it lives in a file called :file:`spam.c` or :file:`spammodule.c`.
-   The output file should be called :file:`spam.pyd` (in Release mode) or
-   :file:`spam_d.pyd` (in Debug mode). The extension :file:`.pyd` was chosen
-   to avoid confusion with a system library :file:`spam.dll` to which your module
-   could be a Python interface.
-
-   Now your options are:
-
-#. Copy :file:`example.sln` and :file:`example.vcproj`, rename them to
-   :file:`spam.\*`, and edit them by hand, or
-
-#. Create a brand new project; instructions are below.
-
-   In either case, copy :file:`example_nt\\example.def` to :file:`spam\\spam.def`,
-   and edit the new :file:`spam.def` so its second line contains the string
-   '``initspam``'.  If you created a new project yourself, add the file
-   :file:`spam.def` to the project now.  (This is an annoying little file with only
-   two lines.  An alternative approach is to forget about the :file:`.def` file,
-   and add the option :option:`/export:initspam` somewhere to the Link settings, by
-   manually editing the setting in Project Properties dialog).
-
-#. **Creating a brand new project** ---  Use the :menuselection:`File --> New
-   --> Project` dialog to create a new Project Workspace.  Select :guilabel:`Visual
-   C++ Projects/Win32/ Win32 Project`, enter the name (``spam``), and make sure the
-   Location is set to parent of the :file:`spam` directory you have created (which
-   should be a direct subdirectory of the Python build tree, a sibling of
-   :file:`Include` and :file:`PC`).  Select Win32 as the platform (in my version,
-   this is the only choice).  Make sure the Create new workspace radio button is
-   selected.  Click OK.
-
-   You should now create the file :file:`spam.def` as instructed in the previous
-   section. Add the source files to the project, using :menuselection:`Project -->
-   Add Existing Item`. Set the pattern to ``*.*`` and select both :file:`spam.c`
-   and :file:`spam.def` and click OK.  (Inserting them one by one is fine too.)
-
-   Now open the :menuselection:`Project --> spam properties` dialog. You only need
-   to change a few settings.  Make sure :guilabel:`All Configurations` is selected
-   from the :guilabel:`Settings for:` dropdown list.  Select the C/C++ tab.  Choose
-   the General category in the popup menu at the top.  Type the following text in
-   the entry box labeled :guilabel:`Additional Include Directories`::
-
-      ..\Include,..\PC
-
-   Then, choose the General category in the Linker tab, and enter ::
-
-      ..\PCbuild
-
-   in the text box labelled :guilabel:`Additional library Directories`.
-
-   Now you need to add some mode-specific settings:
-
-   Select :guilabel:`Release` in the :guilabel:`Configuration` dropdown list.
-   Choose the :guilabel:`Link` tab, choose the :guilabel:`Input` category, and
-   append ``pythonXY.lib`` to the list in the :guilabel:`Additional Dependencies`
-   box.
-
-   Select :guilabel:`Debug` in the :guilabel:`Configuration` dropdown list, and
-   append ``pythonXY_d.lib`` to the list in the :guilabel:`Additional Dependencies`
-   box.  Then click the C/C++ tab, select :guilabel:`Code Generation`, and select
-   :guilabel:`Multi-threaded Debug DLL` from the :guilabel:`Runtime library`
-   dropdown list.
-
-   Select :guilabel:`Release` again from the :guilabel:`Configuration` dropdown
-   list.  Select :guilabel:`Multi-threaded DLL` from the :guilabel:`Runtime
-   library` dropdown list.
-
-If your module creates a new type, you may have trouble with this line::
-
-   PyVarObject_HEAD_INIT(&PyType_Type, 0)
-
-Static type object initializers in extension modules may cause
-compiles to fail with an error message like "initializer not a
-constant".  This shows up when building DLL under MSVC.  Change it to::
-
-   PyVarObject_HEAD_INIT(NULL, 0)
-
-and add the following to the module initialization function::
-
-   if (PyType_Ready(&MyObject_Type) < 0)
-        return NULL;
