Would it be easier to import the gem under a vendor/ directory so it can be updated using the command line rather than copying files?

Maybe we should also avoid re-namespacing it under Tapioca?

The upstream file has has only 2 changes in the last 5 years, so I doubt this will be a problem for us going forward.

I do want to re-namespace it under Tapioca. If the upstream gem gets loaded along with Tapioca, not changing the namespace will result in various constant redefinition warnings.
