How do I change the text of the Buy Now / Add to Cart button?

I know that those are the only two options, but I'm looking to figure out how to change the text in the buttons at the code level. I would really like to have my homepage (global products list) have the buttons say something like More Info >> instead of Buy Now >>, because when you click the buy now from the global products list it takes you to the listing, so you actually are not "Buying Now" but rather "Getting more information"
