Description: These are Python bindings to the `Parma Polyhedra
        Library <http://bugseng.com/products/ppl/>`__. They were extracted from
        the `sagemath <http://www.sagemath.org/>`__ project, in order to be used
        in non-sage projects. This is GPL-licensed, as is Sagemath.
        
        To build it you need to have both the *ppl* and *gmp* libraries
        installed in a place where distutils can find it. Then,
        
        ::
        
            python setup.py build && python setup.py install
        
        If you have trouble, try adding the desired paths to library\_dirs in
        setup.py as a keyword argument to the Extension constructor.
        
        To use it, simply import the module, create a matrix of Fractions or
        integers, and compute the double description !
        
        .. code:: python
        
            from pyparma import Polyhedron
            import numpy as np
            from fractions import Fraction
        
            fractionize = np.vectorize(lambda x: Fraction(str(x)))
            A = fractionize(np.random.rand(50,3))
            poly = Polyhedron(hrep=A)
            print poly.hrep()
        
        Both H-representation and V-representation follow the CDD format i.e.:
        
        -  H\_rep = [b \| A] where the polyhedron is defined by b + A x >= 0
        -  V\_rep = [t \| V] where V are the stacked vertices (Horizontal
           vectors) and t is the type: 1 for points, 0 for rays/lines.
        
        To run the tests, simply run:
        
        ::
        
            nosetests
        
        From the top-level directory. To run the tests, you need to have the
        `CDD library <http://www.inf.ethz.ch/personal/fukudak/cdd_home/>`__
        installed. I assume that you installed the version that comes with the
        `pycddlib <https://pypi.python.org/pypi/pycddlib/>`__ bindings.
