+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 descriptions 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.
