    (description "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.")
