How can I create custom SEO-friendly URLs in OpenC

Question

How can you customize system URLs in OpenCart? For example, I would like http://example.com/index.php?route=checkout/cart to be displayed as http://example.com/cart

I know OpenCart provides SEO URLs for products, categories, manufacturers and information pages, but it doesn't look like there is anything built-in (at least prior to version 1.5.0) for anything else.
