authors should use to write posts. Just write the relevant reader
procedure and Haunt will happily work with that format. Likewise,
Haunt has no opinion about how authors structure their sites. Haunt

Atom feeds, but authors should feel empowered to tweak them, write
replacements, or add new builders to do things that the Haunt hackers
didn't think of.")
