I try to keep as few dependencies as possible to make installation easier, but here's a small guide to hub integration, the easy way to download .var packages. You can find a lot more info in MacGruber's guide.

It will give you the option to download everything you need that's available in the hub:

If you want to know what is needed for a specific package, check the ".depend.txt" that's included with most releases.
