+Passing Interface (MPI) standard for the Python programming language, allowing
+any Python program to exploit multiple processors.
+
+mpi4py is constructed on top of the MPI-1/MPI-2 specification and provides an
+object oriented interface which closely follows MPI-2 C++ bindings. It
+supports point-to-point and collective communications of any picklable Python
+object as well as optimized communications of Python objects (such as NumPy
+arrays) that expose a buffer interface.")
