graph-tool是一个Python程序库，包括目前几乎所有成熟的图论算法和函数，底层使用C++语言的Boost Graph Libraries程序库实现所以运算速度远高于networkx。但是其官网服务器速度很慢，又没有离线文档可供使用。于是我将其官网文档做成PDF格式，即本资料。

Graph-tool is an efficient Python module for manipulation and statistical analysis of graphs (a.k.a. networks). Contrary to most other python modules with similar functionality, the core data structures and algorithms are implemented in C++, making extensive use of template metaprogramming, based heavily on the Boost Graph Library. This confers it a level of performance that is comparable (both in memory usage and computation time) to that of a pure C/C++ library.
