说明：  Lua 本身是以简单优雅为本，着眼于处理那些C 不擅长的任务。借助C/C++为其扩展，Lua 可闪现无穷魅力。Lua 本身完全遵循ANSI C 而写成，只要有C 编译器的地方，Lua 便可发挥她的力量。Lua 不需要追求Python 那样的大而全的库，太多的累赘，反而会破坏她的优美。 语言的优美，来自于使用者自己的感悟。Lua 的优雅，也只有使用后才会明白。
(Product Description: Lua is becoming the language of choice for anyone who needs a scripting language that is simple， efficient， extensible， portable， and free. Currently， Lua is being used in areas ranging from embedded systems to Web development and is widely spread in the game industry， where knowledge of Lua is an indisputable asset. Programming in Lua is the official book about the language， giving a solid base for any programmer who wants to use Lua. Authored by Roberto Ierusalimschy， the chief architect of the language， it covers all aspects of Lua 5.0---from the basics to its API with C---explaining how to make good use of its features and giving numerous code examples. Programming in Lua is targeted at people with some programming background， but does not assume any prior knowledge about Lua or other scripting languages. )
