What can Nuitka do?

I tried that, and it still gives me the same message.
This is the Windows path, right?  In it, among other
paths, I have:

    C:\Python27\Scripts\

(or without the last "\" also, though it should
not matter, right?)

The nuitka file starts with 

    #!C:\Python27_32\python.exe

and is a Python script. It says in a docstring, 

""""
This is the main program of Nuitka, it 
checks the options and then translates
one or more modules to a C++ source code 
using Python C/API in a build directory
compiles it to either an executable or an 
extension module that can contain other 
modules. """

I'm confused as to why it's not just a .py
file.  The nuitka.bat, aside from some
remarks, is this:

    @echo off
    setlocal

    "%~dp0..\python" "%~dp0nuitka" %*

    endlocal
