Being picky you want to add it to your sys.path value

Python loads sys.path from the values in PYTHONPATH which is
an OS environment variable. Modifying PYTHONPATH after you
start Python will have no effect on the current session. PYTHONPATH
changes will only affect the next session you start.

The snag with this is you need to do it every time you want to use
swampy. To make it apply in every session then you need to add it to
PYTHONPATH.

And Python automatically appends any folders it finds in
PYTHONPATH when it starts up.
