Hi,

it's not at all my intention to discourage this project. I hope Leo Mao can use the uvml package as a starting point for further improvements. Since most vectorized math libraries share a very similar interface, I think the actual choice of the library could be made a configurable option. Adapting uvml to use e.g. yeppp instead of MKL should be straightforward. Similar to numpy or scipy built with MKL lapack and distributed by enthought or Christoph Gohlke, using MKL should not be ruled out completely.
