-   PATH C:\Python23;%PATH%
-

-everybody to be able to run Python on the machine.
-
-If you aren't confident doing any of these manipulations yourself, ask for help!
-At this stage you may want to reboot your system to make absolutely sure the new
-setting has taken effect.  You probably won't need to reboot for Windows NT, XP
-or 2000.  You can also avoid it in earlier versions by editing the file
-``C:\WINDOWS\COMMAND\CMDINIT.BAT`` instead of ``AUTOEXEC.BAT``.
-
-You should now be able to start a new command window, enter ``python`` at the
-``C:\>`` (or whatever) prompt, and see the ``>>>`` prompt that indicates the
-Python interpreter is reading interactive commands.
-
-Let's suppose you have a program called ``pytest.py`` in directory
-``C:\Steve\Projects\Python``.  A session to run that program might look like
-this::
-
-   C:\> cd \Steve\Projects\Python
-   C:\Steve\Projects\Python> python pytest.py
-
-Because you added a file name to the command to start the interpreter, when it
-starts up it reads the Python script in the named file, compiles it, executes
-it, and terminates, so you see another ``C:\>`` prompt.  You might also have
-entered ::
-
-   C:\> python \Steve\Projects\Python\pytest.py
-
-if you hadn't wanted to change your current directory.
-
-Under NT, 2000 and XP you may well find that the installation process has also
-arranged that the command ``pytest.py`` (or, if the file isn't in the current
-directory, ``C:\Steve\Projects\Python\pytest.py``) will automatically recognize
-the ".py" extension and run the Python interpreter on the named file. Using this
-feature is fine, but *some* versions of Windows have bugs which mean that this
-form isn't exactly equivalent to using the interpreter explicitly, so be
-careful.
-
-The important things to remember are:
-
-1. Start Python from the Start Menu, or make sure the PATH is set correctly so
-   Windows can find the Python interpreter. ::
-
-      python
-
-   should give you a '>>>' prompt from the Python interpreter. Don't forget the
-   CTRL-Z and ENTER to terminate the interpreter (and, if you started the window
-   from the Start Menu, make the window disappear).
-
-2. Once this works, you run programs with commands::
-
-      python {program-file}
-
-3. When you know the commands to use you can build Windows shortcuts to run the
-   Python interpreter on any of your scripts, naming particular working
-   directories, and adding them to your menus.  Take a look at ::
-
-      python --help

+On Windows, the standard Python installer already associates the .py
 extension with a file type (Python.File) and gives that file type an open
 command that runs the interpreter (``D:\Program Files\Python\python.exe "%1"
 %*``).  This is enough to make scripts executable from the command prompt as
 'foo.py'.  If you'd rather be able to execute the script by simple typing 'foo'
 with no extension you need to add .py to the PATHEXT environment variable.
 
-On Windows NT, the steps taken by the installer as described above allow you to
-run a script with 'foo.py', but a longtime bug in the NT command processor
-prevents you from redirecting the input or output of any script executed in this

-
-and enter the following line (making any specific changes that your system may
-need)::
-
-    .py :REG_SZ: c:\<path to python>\python.exe -u %s %s
-
-This line will allow you to call your script with a simple reference like:
-``http://yourserver/scripts/yourscript.py`` provided "scripts" is an
-"executable" directory for your server (which it usually is by default).  The
-:option:`-u` flag specifies unbuffered and binary mode for stdin - needed when
-working with binary data.
-
-In addition, it is recommended that using ".py" may not be a good idea for the
-file extensions when used in this context (you might want to reserve ``*.py``
-for support modules and use ``*.cgi`` or ``*.cgp`` for "main program" scripts).

-Why doesn't os.popen() work in PythonWin on NT?

-The reason that os.popen() doesn't work from within PythonWin is due to a bug in

-
-You should use the win32pipe module's popen() instead which doesn't depend on

-If you can't change compilers or flags, try using :c:func:`Py_RunSimpleString`.
-A trick to get it to run an arbitrary file is to construct a call to
