def apply(name: String, exitValue: => Int): ProcessBuilder

Creates a scala.sys.process.ProcessBuilder from a String name and a Boolean.

def apply(url: URL): URLBuilder

Creates a scala.sys.process.ProcessBuilder from a java.net.URL.

Creates a scala.sys.process.ProcessBuilder from a java.net.URL. This ProcessBuilder can then be used as a Source, so that one can pipe things from it.

def apply(file: File): FileBuilder

Creates a scala.sys.process.ProcessBuilder from a java.io.File.

Creates a scala.sys.process.ProcessBuilder from a java.io.File. This ProcessBuilder can then be used as a Source or a Sink, so one can pipe things from and to it.
