Poco尽量包含了C++网络编程相关的库，包括网络，数据压缩，数据库，以及一些相关的C＋＋基础库比如boost等，他的目标是建立一个类似cocoa或者.net framework的王国。
The POCO C++ Libraries are...
> a collection of C++ class libraries, similar in concept to the Java
Class Library, the .NET Framework or Apple's Cocoa;
> focused on "internet-age" network-centric applications;
> written in efficient, modern ANSI/ISO Standard C++ and based
on the C++ Standard Library/STL;
> highly portable and available on many different platforms;
> Open Source, licensed under the Boost Software License,
> and thus completely free for both commercial and non-
commercial use.
