This WordPress MooTools plugin simply provides you with the latest MooTools JavaScript framework on the front-end of your WordPress website. It makes use of the <code>wp_head</code> WordPress action hook in order to insert code into the <code><head></code> section of your layout. The MooTools framework will be referenced in your markup as a JavaScript file after it has been safely enqueued using the WordPress <code>wp_enqueue_script</code> function.
