Yes, add it to the list of packages in setup.py - see variable PACKAGES
(Patrick will need to do this at some point, but you could do it now for
your local testing).

It looks like Patrick is using some modern Python 3 only syntax for
type annotation, likely this would work:

def __init__(self, length=None):

However, there are lots of similar changes needed. It would be
better to think about moving to Python 3 if you want to try this
code as it is written.
