Just to say that, thanks to Matthew Brett, binary wheels for Mac OS X
are now available, for Python versions 2.7, 3.3, and 3.4. This means
that, if you're on that platform, you won't have to build from source!
As usual, just run `pip install pyviennacl`, and please report any
issues you encounter to https://github.com/viennacl/pyviennacl-dev/issues !

Thanks,

Toby

> * sparse (compressed, co-ordinate, ELL, and hybrid) and dense
>   (row-major and column-major) matrices, vectors and scalars on your
>   compute device using OpenCL;
> * standard arithmetic operations and mathematical functions;
> * fast matrix products for sparse and dense matrices, and inner and
>   outer products for vectors;
> * direct solvers for dense triangular systems;
> * iterative solvers for sparse and dense systems, using the BiCGStab,
>   CG, and GMRES algorithms;
> * iterative algorithms for eigenvalue estimation problems.

> PyViennaCL has also been designed for straightforward use in the context
