+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.")
