Boost.Intrusive is a library presenting some intrusive containers to the world of C++. Intrusive containers are special containers that offer better performance and exception safety guarantees than non-intrusive containers (like STL containers). 
Boost.Intrusive 是一個將介入式容器引入到C++世界的庫。介入式容器是一種特殊的容器，它提供比非介入式容器(如STL容器) 更好的性能 和異常安全保證。

The performance benefits of intrusive containers makes them ideal as a building block to efficiently construct complex containers like multi-index containers or to design high performance code like memory allocation algorithms.
介入式容器的性能優點使得它們成為一種構建塊，用以高效地構造複雜容器，如多索引容器，或者用以設計高性能代碼，如內存分配算法。

While intrusive containers were and are widely used in C, they became more and more forgotten in C++ due to the presence of the standard containers which don't support intrusive techniques.Boost.Intrusive not only reintroduces this technique to C++, but also encapsulates the implementation in STL-like interfaces. Hence anyone familiar with standard containers can easily use Boost.Intrusive.
雖然介入式容器在C中被廣泛使用，但是在C++中卻被日漸遺忘，這是由於不支持介入式技術的標準容器的出現。Boost.Intrusive 不僅重新將這一技術引入到C++，而且還將實現封裝為類似於STL的接口。所以每一個熟悉標準容器的人都可以很容易地使用 Boost.Intrusive。

There is no need to compile anything to use Boost.Intrusive, since it's a header only library. Just include your Boost header directory in your compiler include path.
使用 Boost.Intrusive 不需要編譯任何東西，因為它是一個僅有頭文件的庫。只需要將你的 Boost 頭文件目錄包含在你的編譯器包含路徑中就可以了。
