I'd like to overwrite the way this file works:

app\code\core\Mage\Catalog\Block\Product\View\Options\Type\Select.php

I thought all I had to do was copy it to:

app\code\**local**\Mage\Catalog\Block\Product\View\Options\Type\Select.php

That does not appear to be working. Is there another option available? My goal is just to change the HTML that is used here.
