# FromString

#### abstract class FromString[+T] extends PartialFunction[String, T]

A general mechanism for defining how a command line argument (always a String) is transformed into an arbitrary type. A few example instances are in the companion object, but in general either IntFromString will suffice or you'll want custom transformers.
