+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.")
