* `SciPy >= 0.10 <http://scipy.org>`__

Known build errors
------------------
On Windows, the error ``Error:unable to find vcvarsall.bat`` means that
distutils is not correctly configured to use the C compiler. Modify (or create,
if not existing) the configuration file ``distutils.cfg`` (located for
example at ``C:\Python26\Lib\distutils\distutils.cfg``) to contain::

    [build]
    compiler=mingw32


Usage Requirements
------------------
* `Scipy <http://www.scipy.org/>`__
