• 贴一下官方文档：http://click.pocoo.org/5/opti...
• 解释一下关键性词汇

Boolean flags are options that can be enabled or disabled. This can be accomplished by defining two flags in one go separated by a slash (/) for enabling or disabling the option. (If a slash is in an option string, Click automatically knows that it’s a boolean flag and will pass is_flag=True implicitly.) Click always wants you to provide an enable and disable flag so that you can change the default later.

显然这句话的意思就是告诉你，当slash(/，斜杠)在参数中的时候，需要打开为True
