Yeah, seriously. I just did some work with the s7 implementation of Scheme. "Only two files!"

I think in all fairness, I think the idea is that you should just drop it in your source without needing to worry about git subrepos (or whatever). But it would be perhaps more elegant to split it up in the repo and have a script stitch it together into the "only two files".

Also s7 turned out to be much easier to include than the other ones I was considering, so I guess I shouldn't be mocking it.
