# Public: Middleware for Rack applications. Any errors raised by the upstream
# application will be delivered to Honeybadger and re-raised.
#
# Examples:
#
# require 'honeybadger/rack/error_notifier'
#
# Honeybadger.configure do |config|
# config.api_key = 'my_api_key'
# end
#
# app = Rack::Builder.app do
# run lambda { |env| raise "Rack down" }
# end
#
# use Honeybadger::Rack::ErrorNotifier
# run app
#
# Use a standard Honeybadger.configure call to configure your api key.
