Mongodb: Does the stats command show me the capped size setting?

I am looking around my mongo instance. One of the collections was created as capped:

db.createCollection("userObjects", { capped:true, size:400000000000 })

But when I look at the db.userObjects.stats(), I don't see any flag that indicates it is capped, or the cap size.

Am I missing something? (Is there another place to look?)
