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.
