          开始设置二进制化初始信息.
          所有的信息都会保存在 #{Ocean.config.config_file} 文件中.
          %w[swordfish_dev.yml swordfish_debug_iphoneos.yml swordfish_release_iphoneos.yml] 
          你可以在对应目录下手动添加编辑该文件. 文件包含的配置信息样式如下：

          #{Ocean.config.default_config.to_yaml}
        EOF
      end

      def done_message
        print "\n设置完成.\n".green
