原文:你也可以玩转Skype -- 基于Skype API开发外壳程序入门

Skype是目前这个星球上最厉害的IM+VOIP软件，Skype现在已经改变了全球2.8亿人的生活方式。你，值得拥有！ ：）

Skype中文官网：http://skype.tom.com/

Skype全球官网：http://www.skype.com/

Skype也是世界上最开放，最具创新意识的IM工具，他提供了Skype API， Skype4COM， Skype4Java几种形式的开发接口给Skype爱好者编写Skype的交互程序或者Skype的插件。你可以使用任何你熟悉的语言，比如C/C++,VB, C#,Delphi，Java甚至PHP，VBScript。通过你的专业知识，去影响2.8亿的Skype用户。你也可以做到！：）
