+  MPI for Python (mpi4py) provides bindings of the Message Passing
+  Interface (MPI) standard for the Python programming language,
+  allowing any Python program to exploit multiple processors.
+  This package 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 (sends, receives) and
+  collective (broadcasts, scatters, gathers) communications of any
+  picklable Python object as well as optimized communications of
+  Python object exposing the single-segment buffer interface (NumPy
+  arrays, builtin bytes/string/array objects).
