In order to run this script, you need:

- Python 2.5 (or higher) http://www.python.org/download/releases/2.5/
- matplotlib (a.k.a. PyLab) http://matplotlib.sourceforge.net/
- SciPy http://www.scipy.org/

If you work under Ubuntu / Debian, you can use "apt-get" to
easily install these packages:

>> sudo apt-get install python2.5 python-scipy python-matplotlib

For Mac OS X, you can use "fink", which is a command-line tool like
apt-get. For windows, download and install the binaries from the
websites.

Under Windows and Mac OS X, you might also need the X11 window
manager for displaying the graphics.

Once everything is installed, run the script simply by typing:

>> python maze.py

or

>> python maze_traces.py
