AUTHORS: n.b. The trailing whitespace between paragraphs is important and should not be removed. The whitespace creates paragraphs in the RDoc output.

This specification aims to formalize the Rack protocol. You can (and should) use Rack::Lint to enforce it.

When you develop middleware, be sure to add a Lint before and after to catch all mistakes.
