  short: 'u',
  description : "操作するスライドのURL"

var options = argv.run().options;

var chromeDriver = new webdriver.Builder()
                        .usingServer('http://localhost:4444/wd/hub')
                        .withCapabilities( webdriver.Capabilities.chrome() )

});

leftBtnServer.on("send", function(e){
