 An [OpenTracing](https://opentracing.io/)-compliant, simple, and extensible
 distributed tracing library.
 
-+ _Simple:_ add a single `MonadTrace` constraint to start tracing (without making
-  your code harder to test)!
-+ _Extensible:_ use the built-in [Zipkin](http://zipkin.io) backend or implement
-  your own.
