Steps to installing KupoChart:

1) Install a web server that supports PHP (such as Apache)
2) Install PHP.
3) Install Image_Graph from http://pear.veggerby.dk/
   A simple way to do this is:

	1) Install PEAR (which is to PHP what CPAN is to Perl)
	2) Run 'pear install image_graph' as root, and follow the
	   prompts. You may be asked to install some prerequisite
	   software, update pear itself, etc.

4) Place kupochart.php somewhere in a directory hosted via your
   web server. Make sure your web server is set up to parse .php
   files as PHP, and that Image_Graph is installed. You may (or
   may not) need to restart your web server after installing some
   of the prerequisites listed above.

5) Test KupoChart!
