// 一、基础
// // 文本段可以标注
// === tag_sample
//     a line of normal game-text

// 带一个选项的默认选择
// choice_sample
// *   choice1
//     result

// // 选择后选项文本消失
// Hello world!
// *	[Hello back!]
// 	Nice to hear from you!

// // 选择后替换文本
// Hello world!
// *	Hello [back!] right back to you!
// 	Nice to hear from you!

// // 选择后替换文本的应用，将简单的选项文本复杂化描述
// "What's that?" my master asked.
// *	"I am somewhat tired[."]," I repeated.
// 	"Really," he responded. "How deleterious."

// // 多选项
// "What's that?" my master asked.
// *	"I am somewhat tired[."]," I repeated.

// *  "I said, this journey is appalling[."] and I want no more of it."
// 	"Ah," he replied, not unkindly. "I see you are feeling frustrated. Tomorrow, things will improve."


//指定knot才能运行

// === the_orient_express === 

// We boarded the train, but where?

// // 可以include其他脚本来选择knot

// === homers_couch ===
// 	+	[Eat another donut]
// 		You eat another donut. -> homers_couch
// 	*	[Get off the couch]

// *	{ visit_paris.met_estelle } [ Telephone Mme Estelle ] -> phone_estell

// // 实际上条件不是看或者没看，而是一个看过几次的整型，因此条件也可以写为：

// // 花括号内的文本可以用或符号隔开作为变量，每次遇见该文段时跳转到下一个字段，叫做alternatives

// // 一些保留字，用于查询游戏状态
