56 * Extended command line parser which handles --foo=value arguments.
58 * The args4j package does not natively handle --foo=value and instead prefers
59 * to see --foo value on the command line. Many users are used to the GNU style
60 * --foo=value long option, so we convert from the GNU style format to the
61 * args4j style format prior to invoking args4j for parsing.
