Class Getopt

java.lang.Object

org.opensolaris.opengrok.util.Getopt

public class Getopt
extends java.lang.Object

A simple implementation of the getopt(3c). It does just implement what I need ;-) Please note that I dislike the way GNU getopt allows mixing of options and arguments, so this version will stop processing options as soon as it encounters an argument.
