+ * Compatibility layer needed for the backend.
+ *
+ * Our backend is based on the Scala 2.11 GenBCode backend and modified so that
+ * it compiles both with dotty and scalac, since the backend uses
+ * scala.tools.nsc.io.*, we need to also provide it.
+ *
+ * See http://dotty.epfl.ch/docs/contributing/backend.html for more information.
