Countr is a web 2.0 AJAX-driven web application that allows you to count anything.

To run the website, you will need to create a file config.php, with contents like so:

<?
$CONFIG = array('host' => 'localhost', 'username' => 'countr', 'password' => 'oranges', 'database' => 'countr');
?>

Modify the details to suit your MySQL database details, then run web/countr.sql in your database.
