// Argument(long, short, defaultValue)
argManager.on(new nodeArgs.Argument('url','u', 'localhost'), function(val, defaultValue) {
    // val will be default value if no value is provided
    console.log('Your url argument has a value of: ' + val);
});

argManager.onDefault(function(defaults) {
    defaults.forEach(function(arg) {
        console.log('Unprefixed argument: ' + arg);
