That's exactly what I wanted _not_ to do, as it ties `Routemaster` tightly to `raven`/Sentry.

My recommandation is to add an `error do ... end` block here (that's the [Sinatra equivalent](http://www.sinatrarb.com/intro.html#Error%20Handling) to Rails' `rescue_in_public`), like so:

```ruby
class Routemaster::Application < Sinatra::Base
  include Routemaster::Mixins::LogException
  ...
  error do
    deliver_exception env['sinatra.error']
  end
end
```
