Well, the package needs access to a fully-functional WP-CLI. I guess an alternative would be to clone the repo for the bootstrap files, and also download `wp-cli.phar` to use WP-CLI.

Now that I've gotten it functional as a proof of concept, I think it needs more baking before it's the "blessed" version. It's working well-enough for my needs at the moment.
