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

# Synopsis:
#
# require 'rack'
# require 'raven'
#
# Raven.configure do |config|
# config.server = 'http://my_dsn'
# end
#
# app = Rack::Builder.app do
# use Raven::Rack
# run lambda { |env| raise "Rack down" }
# end
#
# Use a standard Raven.configure call to configure your server credentials.
