rem Figure out whether to run our class with java or with the scala launcher.

rem creates a shell script as the parent of its Java process, which makes it
rem hard to kill the child with stuff like Process.destroy(). However, for
rem the Spark shell, the wrapper is necessary to properly reset the terminal
rem when we exit, so we allow it to set a variable to launch with scala.
