sys.path is just a list. So in your 'main' module where you do most of
your imports, just append or prepend the path you desire (the search
order is left to right). Although, I believe under Windows creating a
system level or user level PYTHONPATH environment variable will enable
Windows to pick it up. Not 100% sure as I don't have a Windows machine
handy.
