Class CLArgsParser

java.lang.Object

org.apache.commons.cli.avalon.CLArgsParser

public final class CLArgsParser
extends Object

Parser for command line arguments. This parses command lines according to the standard (?) of GNU utilities. Note: This is still used in 1.1 libraries so do not add 1.2+ dependencies. Note that CLArgs uses a backing hashtable for the options index and so duplicate arguments are only returned by getArguments().
