 /**
- * Special version of {@link org.apache.flink.api.java.RemoteEnvironment} that has a reference
- * to a {@link org.apache.flink.api.scala.FlinkILoop}. When execute is called this will
- * use the reference of the ILoop to write the compiled classes of the current session to
- * a Jar file and submit these with the program.
+ * A remote {@link ExecutionEnvironment} for the Scala shell.
