+    """NetworKit is a growing open-source toolkit for large-scale network
+       analysis. Its aim is to provide tools for the analysis of large networks
+       in the size range from thousands to billions of edges. For this purpose,
+       it implements efficient graph algorithms, many of them parallel to
+       utilize multicore architectures. These are meant to compute standard
+       measures of network analysis, such as degree sequences, clustering
+       coefficients, and centrality measures. In this respect, NetworKit is
+       comparable to packages such as NetworkX, albeit with a focus on
+       parallelism and scalability."""
