+%global _description %{expand:
+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, built-in bytes/string/array
+objects).}
