+class RFastcluster(RPackage):
+    """This is a two-in-one package which provides interfaces to both R
+       and 'Python'. It implements fast hierarchical, agglomerative
+       clustering routines. Part of the functionality is designed as drop-in
+       replacement for existing routines: linkage() in the 'SciPy' package
+       'scipy.cluster.hierarchy', hclust() in R's 'stats' package, and the
+       '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. For information on how to install
+       the 'Python' files, see the file INSTALL in the source distribution."""
