noir vs compojure?

Question

I'm having trouble understanding the point of clojure's Noir library. It seems to be a framework written on top of compojure that renames defroute to defpage and calls it a day. Obviously an unfair simplification, but what exactly does Noir bring to the table? Why would I use Noir instead of plain compojure+hiccup?

EDIT/UPDATE: Noir is deprecated, interesting write up here: http://blog.raynes.me/blog/2012/12/13/moving-away-from-noir/.

Answer 1

From the author of Noir himself:

Noir isn't really a replacement for [compojure and hiccup], more of an abstraction over them. It was born out of seeing how a real web-app evolved and what was missing from the ring/compojure/hiccup stack as I built http://www.typewire.io. Also, as I mentioned in one of the other comments, I hope that it will serve as the single "package" to start with web development in Clojure, instead of having to try and cobble it together from the pieces that are out there now. By controlling all of it, I can create a much more cohesive and well defined story for helping people get started. I can also share what I've learned about maintaining websites in Clojure and hopefully encourage patterns that avoid some of the pits I fell into.
