Please see the main PieTree webpage for background, examples, the manual, and the source code. This page just provides a means to try it out without worrying about installation.
Also, please note that this interface is quite preliminary. Robustification and convenience improvements will happen sometime, but this is my first experiment with cgi, and I would be grateful for any advice. The major limitation at the moment is that if there is more than one user at a time, you may accidentally receive someone else's results...
