We should add jbarnes's documentation on EXA. Preferably in a manpage, imo.

Created attachment 3126 [details] [review] xaa-final-doc-updates-1.patch when we do document EXA, we should clearly mark XAA as deprecated.
The documentation currently in the tree for the public interface should be good enough. I do want to document the rest of EXA better, but this bug is done.
