Like the rule of Information Hiding, the Self-Documentation principle governs how we should document modules:
就象信息隐藏的规则, 自包含文档原则决定了我们应该如何对模块写文档:
Self-Documentation principle The designer of a module should strive to make all information about the module part of the module itself. 模块的设计者应该努力让模块的本身包含其所有的信息.
