-module Rack
- # Rack::Builder implements a small DSL to iteratively construct Rack
- # applications.
- #
- # Example:
- #
- # app = Rack::Builder.new {
- # use Rack::CommonLogger
- # use Rack::ShowExceptions
- # map "/lobster" do
- # use Rack::Lint
- # run Rack::Lobster.new
- # end
- # }
- #
- # Or
- #
- # app = Rack::Builder.app do
- # use Rack::CommonLogger
- # lambda { |env| [200, {'Content-Type' => 'text/plain'}, 'OK'] }
- # end
- #
- # +use+ adds a middleware to the stack, +run+ dispatches to an application.
- # You can use +map+ to construct a Rack::URLMap in a convenient way.
