%description

Pythran is an ahead of time compiler for a subset of the Python language, with

a focus on scientific computing. It takes a Python module annotated with a few

interface description and turns it into a native Python module with the same

interface, but (hopefully) faster. It is meant to efficiently compile

scientific programs, and takes advantage of multi-cores and SIMD

instruction units.
