Aliasing resources?

I have a resource and an associated controller called Person.

I would like to generate some routes for the PersonController but call
them by another name, like Registration, so that I can access the
PersonController routes through a different name.

Is there a way for me to do something like this:

map.resources :people, :alias => :registration (or :as =>

so that I can get access to my PeopleController through another name for
use in a different front-end context?

Or do I need to build my differently named routes by hand?
