module Airbrake
  # Middleware for Sinatra applications. Any errors raised by the upstream
  # application will be delivered to Airbrake and re-raised.

  #   require 'sinatra'
  #   require 'airbrake'

  #   Airbrake.configure do |config|
  #     config.api_key = 'my api key'
  #   end

  #   use Airbrake::Sinatra

  #   get '/' do
  #     raise "Sinatra has left the building"
  #   end
  #
  # Use a standard Airbrake.configure call to configure your api key.
