中文版序

Scheme is comparable to Go, a traditional Chinese board game.The reason is that both of them generate beautiful code/board from extremely simple rules, which are one of the simplest in the areas (programming languages and board games).

The simple rules and infinite beautiful variation make them attractive to intelligent people.The nature, at the same time, makes them rather difficult to be mastered.

I wrote the tutorial to provide the key to master the language.I believe the Chinese translation helps many programmers to master Scheme programming language.

Scheme恰似中国传统棋盘游戏——围棋。

这是因为它们都可以根据相当简单的规则产生美妙的代码或者棋局，这些规则在它们的领域中都是最简单的。简单的规则，无限的美妙变幻，这些都无比吸引那些聪明的家伙。但同时，大自然却让它们难以掌握。

我编写这份教程以打开掌握Scheme之门。我相信中文译版会帮助更多的程序员掌握Scheme程序设计语言。
