These don't seem to capture that they can be an empty list. Not sure if that is important, since that is an odd usage.

I don't like having them all the way on the bottom either, and the page is describing things in a bottom-up way. Perhaps we should invert it, and explain the attributes and macro first? |

Fixes #384
Partial r? @ehuss for grammar additions.
I put a couple questions into comments into the source itself.
I also wonder if making each configuration option set by the compiler its own section like I did is too spacey. I could bring it back down into a list if y'all agree with that.
