# 6.3 气球

在许多比赛中特定颜色的气球将分发给解出特定问题的队伍。DOMjudge 可以在这个过程中起作用：web 界面和通知进程都可以用于提醒一个新的气球需要被分发。注意每次只能用一个。

该基于 web 的工具可以通过裁判界面的主页访问，每个气球都要被分发者 check off （大概是划道杠表示已经发出去了的意思）。

对于进程，通过设置 `etc/domserver-config.php` 中的 `BALLOON_CMD` 来选择通知的发送方式。比如可以给邮箱发邮件或者给打印机发送打印信息。设置完成后，启动 `bin/balloons` 来开启通知。

封榜后通知将停止发送，但可以通过启用 `show_balloons_postfreeze` 选项来继续发送气球通知。
