I am not a very good aliaser. But I'm the best I can be. If I'm
aliasing to a Resource that generates links, and it uses any parts
of request.prepath to do so, the links will not be relative to the
aliased path, but rather to the aliased-to path. That I can't
alias static.File directory listings that nicely. However, I can
still be useful, as many resources will play nice.
