+     "This package implements time series clustering along with optimized
+techniques related to the dynamic time warping distance and its corresponding
+lower bounds.  The implementations of partitional, hierarchical, fuzzy, k-Shape
+and TADPole clustering are available.  Functionality can be easily extended 
with
+custom distance measures and centroid definitions.  Implementations of 
@acronym{
+DTW, dynamic time warping} barycenter averaging, a distance based on global
+alignment kernels, and the soft-DTW distance and centroid routines are also
+provided.  All included distance functions have custom loops optimized for the
+calculation of cross-distance matrices, including parallelization support.
+Several cluster validity indices are included.")
