+"""PyAMS_utils list module
+
+This module is dedicated to lists and iterators management. It provides function to extract
+unique values from a list or iterator in their original order, or to iterate over an iterator in
+random order; it also provides a "boolean_iter" function (usable as TALES extension) to check if
+an iterator returns at least one value, without consuming this iterator (the function returns a
+tuple containing a boolean value to specify if iterator is empty or not, and the original
+iterator).
