I'm ok with dropping the Authors section then.

This sounds reasonable for the traversing section. I'm a bit confused
about how it would work for the walking section though. I don't get the
notion of path components there because the API is focused around one
level of a tree. Maybe it should just be called the entry's name in that
case?
