Stupid little timer for timing grizzled.io.RichInputStream.copyTo. Meant to be run from the sbt console. sample-session shows a sample session copying a file named "src" to a file named "dest".

def timeit(f: => Unit): Long = {
  val t = System.currentTimeMillis()
  f
  System.currentTimeMillis() - t
}

import grizzled.file.util._
import java.io.File

def f(src: String, dest: String) : Unit = {
  val s = new File(src)
  val d = new File(dest)
  println(timeit { copyFile(s, d) })
}
