2.  final class FileTailSource extends GraphStage[SourceShape[ByteString]]

   INTERNAL API

   INTERNAL API

   Read the entire contents of a file, and then when the end is reached, keep reading newly appended data. Like the unix command tail -f.

   Aborting the stage can be done by combining with a akka.stream.KillSwitch

   To use the stage from Scala see the factory methods in akka.stream.alpakka.file.scaladsl.FileTailSource
