This is a work-in-progress, but the idea is it can convert between our
wiki and the SDL header's doxygen comments, so we can attempt to keep them
in sync.
This might be a fool's errand, but I'm optimistic it'll work enough that we
can clean up little issues as we go, as long as we have some discipline
about how we write documentation. If nothing else, it's going to result in
a solid spring-cleaning of both the wiki and the headers!
