Build Requirements
------------------
* `Python >= 2.5 <http://python.org>`_
* `Numpy >= 1.4 <http://numpy.scipy.org/>`_
* `Cython >= 0.13 <http://www.cython.org/>`_

Known build errors
------------------

If Cython compilation fails with the error ``cpython.pycapsule.pxd not
found`` (for Cython 0.14), try to `install Cython 0.15
<http://www.cython.org/#download>`_ instead. 

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

    [build]
    compiler=mingw32


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

Optional Requirements

functionality is only available with the following installed:

`PyQt4 <http://wiki.python.org/moin/PyQt>`_
   The `qt` plugin that provides `imshow` and `scivi`.
