To be honest, I spent well over an hour yesterday attempting to piece through how one might use `resource.stage` for that and wasn't able to find a formula with a use case similar to this (extracting the archive to a known location and passing that location off to the actual installation script).

If you could point me toward a formula in which `resource.stage` is used for extraction, and the path to which the archive was extracted is returned for the main package's use, I'd be able to go forward with this, but at the moment it isn't clear.
