'''This program illustrates pixel-based manipulation of images using PIL.

Jeff Ondich, 31 Oct 2007 (boo!), for CS 111.

This program requires you to install PIL (the Python Imaging Library), which
you can get from http://www.pythonware.com/products/pil/ if it's not already
installed on the computer you are using.  It is already installed in the
CS labs in the CMC.
