Macaroons are better than cookies!

libmacaroons is an open source implementation of macaroons, the flexible
bearer tokens that work great in distributed systems.  Like cookies,
macaroons are bearer tokens that enable applications to ascertain
whether their holders' actions are authorized.  But macaroons are better
than cookies!  See the README for more information.
