+ "The analysis of environmental data often requires the detection of
+trends and change-points. This package includes tests for trend
+detection (Cox-Stuart Trend Test, Mann-Kendall Trend Test, (correlated)
+Hirsch-Slack Test, partial Mann-Kendall Trend Test, multivariate (multisite)
+Mann-Kendall Trend Test, (Seasonal) Sen's slope, partial Pearson and Spearman
+correlation trend test), change-point detection (Lanzante's test procedures,
+Pettitt's test, Buishand Range Test, Buishand U Test, Standard Normal
+Homogeinity Test), detection of non-randomness (Wallis-Moore Phase Frequency
+Test, Bartels rank von Neumann's ratio test, Wald-Wolfowitz Test) and the two
+sample Robust Rank-Order Distributional Test.")
