工具的使用(Using the utilities)
Application
Twisted程序通常和twisted.application.service.Application协作。这个类通常管理着一个运行中的服务器的所有持久化配置信息 —— 哪些端口需要绑定、哪些连接必须被保持或者被尝试、哪些动作需要周期性的去做，以及几乎所有的一切。它是服务树中的根对象，实现了IService接口。

序列化(Serialization)
TAP
Twisted Application Pickle。这种格式由本地的Python pickle包提供支持。这种格式虽然人类看不懂，但是存取是最快的。
A Twisted Application Pickle. This format is supported by the native Python pickle support. While not being human readable, this format is the fastest to load and save.
TAX
Twisted 包含 twisted.persisted.marmalade, 支持对遵循XML标准的一种格式进行序列化和解序列化的模块。这种格式是人类可读可编辑的。
Twisted contains twisted.persisted.marmalade, a module that supports serializing and deserializing from a format which follows the XML standard. This format is human readable and editable.
TAS
Twisted 包含 twisted.persisted.aot，一个支持序列化为Python代码的模块。它的好处在于使用了Python自身的语法分析器，并且以后可以手工将这段代码加入到文件中去。
Twisted contains twisted.persisted.aot, a module that supports serializing into Python source. This has the advantage of using Python's own parser and being able to later manually add Python code to the file.
