Once you know how it works, you should be able to request info from the support staff of your software, or get in there and modify it yourself.
Do I cut and paste the sample code into my cart?
No, very bad idea. Read the documentation, upload the samples to your server, and experiment with them outside your cart. Get a "feel" for how they work, get their examples working on their own. Once you get to that point, you should be able to figure out how to add it to your cart, or ask questions authoritatively of the cart software's support forum or support staff.
The documentation is fairly cryptic but in my experience the answers are mostly all in their PDF's. I found I had to read over a couple sections, have zero understanding of what I read, read other sections, then was able to go back to the rocket-science sections and understand them. :-) Seems difficult at first, but once you digest how it all works, UPS integration is not that hard.
