org.codehaus.groovy.grails.cli.parsing
[Java] Class CommandLineParser

java.lang.Object
  org.codehaus.groovy.grails.cli.parsing.CommandLineParser

public class CommandLineParser
extends java.lang.Object

Command line parser that parses arguments to the command line. Written as a replacement for Commons CLI because it doesn't support unknown arguments and requires all arguments to be declared up front. It also doesn't support command options with hyphens. This class gets around those problems.
