I am upgrading my site from ZC 1.3.8a to 1.5.1. In the 1.3.8a installation, there are these two UPS files:

includes\languages\english\modules\shipping\ups.php
includes\modules\shipping\ups.php

However, I cannot find the corresponding files in the 1.5.1 installation. I thought they might be from a UPS addon, but haven't found them yet.

Where do they come from? Where did they go in ZC 1.5.1?

Thanks! Any help would be greatly appreciated!
