_drawrating.php file in includes directory

[McMendo]

I've just realised that there is a file _drawrating.php in my includes/ directory, which I can't relate but which appears to be related to some rating system?

It is not in the default installation. Does anyone know what this file is?

PHP Code:

<?php
/*
Page:           _drawrating.php
Created:        Aug 2006

The function that draws the rating bar.

You have installed a modification that adds this (looks like AME).

I thought so. I wasn't sure of which modification did it.

Thank You
