 There are a number of other wrappings into Python of Tox core.
 This one uses CTYPES which has its merits - there is no need to
 recompile anything as with Cython - change the Python file and it's done.
+CTYPES code can be brittle, segfaulting if you got things wrong,
+but if your wrapping is right, it is very efficient and easy to work on.
