+ (description
+ "This package contains procedures for depth-based supervised learning,
+which are entirely non-parametric, in particular the DDalpha-procedure (Lange,
+Mosler and Mozharovskyi, 2014). The training data sample is transformed by a
+statistical depth function to a compact low-dimensional space, where the final
+classification is done. It also offers an extension to functional data and
+routines for calculating certain notions of statistical depth functions. 50
+multivariate and 5 functional classification problems are included.")
