This isn't correct. I don't know what you should put here with all the different
licenses that cover parts of this directory.

Actually, I should clarify. This could be correct.

It is possible (depending on what the licenses actually require) that this
entire thing can be covered under just the MIT license, but it's complicated.

Taking a quick look at the license files, I believe the package can be
distributed with an Apache v2 license, but I'd talk with someone who knows
better.
