Routes started out as a Python re-implementation of the Rails routes system for mapping URL's to Controllers/Actions and generating URLs. Routes makes it easy to create pretty and concise URL's that are RESTful with little effort. Routes 2 is a rewrite that diverges from Rails and makes the syntax more deterministic but retains the original feel.
