How to access/display Manufacturer Description in product-list.tpl

[benbtwd]

Hi, I'm trying to customize a copy of the bootstrap theme in version 1.6.2. I need to be able to access the manufacturer description for each product that is listed. I tried overriding Product.php and duplicating every reference to manufacturer name with a new variable for manufacturer description, thinking this property would then be available through the product just like manufacturer name is like {$product.manufacturer_name} using  {$product.manufacturer_description}. This seems to return nothing, though. Any help would be much appreciated!
