Example of a `findScript.scala.html` template in [Play](https://github.com/vmunier/play-scalajs.g8/blob/856e70e60f518db27cd8db524abf0bed1d0fc59d/src/main/g8/server/app/views/findScript.scala.html) and [Akka HTTP](https://github.com/vmunier/akka-http-scalajs.g8/blob/961276766e4c69caf9ad6aee9a14b283cc2bc946/src/main/g8/server/src/main/twirl/%24package%24/findScript.scala.html).*
