Right, but we probably want that information in the man page itself formatted in a way that is consistent with other man pages. There is also a question of whether we only want a subset of the options in the man page, as clang does right now, or if we want a comprehensive reference.

For now, I am fine with linking to an external page, but eventually, the man page should be self-contained.
