description         A high performance implementation of HDBSCAN clustering.

long_description    HDBSCAN - Hierarchical Density-Based Spatial \
                    Clustering of Applications with Noise. Performs \
                    DBSCAN over varying epsilon values and integrates \
                    the result to find a clustering that gives the \
                    best stability over epsilon. This allows HDBSCAN \
                    to find clusters of varying densities (unlike \
                    DBSCAN), and be more robust to parameter \
                    selection. In practice this means that HDBSCAN \
                    returns a good clustering straight away with \
                    little or no parameter tuning -- and the primary \
                    parameter, minimum cluster size, is intuitive and \
                    easy to select. HDBSCAN is ideal for exploratory \
                    data analysis\; it's a fast and robust algorithm \
                    that you can trust to return meaningful clusters \
                    (if there are any).
