+frame.  It offers three methods to process data:
+@enumerate
+@item full but slow implementation using all the data that has cubic
+  complexity;
+@item a fully randomized method;
+@item a method using k-nearest neighbours.
+@end enumerate
+These algorithms are well suited for high dimensional data outlier
+detection.")
