+ (description
+ "Parametric time warping aligns patterns. It aims to put corresponding
+features at the same locations. The algorithm searches for an optimal polynomial
+describing the warping. It is possible to align one sample to a reference, several
+samples to the same reference, or several samples to several references. One can
+choose between calculating individual warpings, or one global warping for a set
+of samples and one reference. Two optimization criteria are implemented: @acronym{
+RMS, Root Mean Square} error and @acronym{WCC, Weighted Cross Correlation}. Both
+warping of peak profiles and of peak lists are supported.")
