+routines.  Part of the functionality is designed as drop-in replacement for
+existing routines: @code{linkage()} in the SciPy package
address@hidden, @code{hclust()} in R's @code{stats} package,
+and the @code{flashClust} package.  It provides the same functionality with
+the benefit of a much faster implementation.  Moreover, there are
+memory-saving routines for clustering of vector data, which go beyond what the
+existing packages provide.")
