### Install scipy module for Python (optional)

The module named scipy (Scientific Python) is not necessary for the Gildas-Python binding, but it provides useful functionalities you may want. The build and installation process is exactly the same as for NumPy:

1. Download scipy from: http://www.scipy.org/Download

2. Unpack and compile scipy:

       cd <compilation-directory>
       tar xvzf scipy-0.7.1.tar.gz
       cd scipy-0.7.1
       python setup.py build --fcompiler=<compiler>

3. Install:

       python setup.py install [--prefix=/some/custom/installation/prefix]

   If you provide a custom installation path (–prefix), use the same as for NumPy: you will not have to augment again the $PYTHONPATH for this second module.

4. Check the installation:

       import scipy
       scipy
       scipy.__version__
       from scipy.special import jn

   (the last line tries to import the Bessel functions named jn).
