+
+    A comprehensive implementation of dynamic time warping (DTW) algorithms in
+    R.  DTW computes the optimal (least cumulative distance) alignment between
+    points of two time series.  Common DTW variants covered include local
+    (slope) and global (window) constraints, subsequence matches, arbitrary
+    distance definitions, normalizations, minimum variance matching, and so on.
+    Provides cumulative distances, alignments, specialized plot styles, etc.,
+    as described in Giorgino (2009) <doi:10.18637/jss.v031.i07>."""
