 pNbody python module
 http://obswww.unige.ch/~revaz/pNbody/index.html
 
 Release 4.0 (Feruary, 2008)
 
 
 --------------------------------------------------------------------

   * C compiler

   * PIL (the Python Image Library module with python-imaging-tk enabled)
   
 --------------------------------------------------------------------
 Build instructions for UNIX
 --------------------------------------------------------------------
 
 
 1. Unpack the pNbody distribution (the file pNbody-3.0.tgz)
    in your Python extensions directory (if you have one.  If
    not, feel free to unpack it in any other suitable directory).
 
         $ cd Python-2.5/Extensions # example
         $ tar -xzf pNbody-4.0.tgz
 
 
 2. Using Python 2.3 or later, you can use the setup.py
    script to build the module.  The following commands should do
    the trick:
 
         $ python setup.py build
         $ python setup.py install
 
    (depending on how Python has been installed on your machine,
    you might have to log in as a superuser to run the 'install'
    command.)
 
    If the setup.py command finishes without any errors, you're
    done!
