NAME
ordsets - Functions for Manipulating Sets as Ordered Lists
DESCRIPTION
Sets are collections of elements with no duplicate elements. An ordset is a representation of a set, where an ordered list is used to store the elements of the set. An ordered list is more efficient than an unordered list.
This module provides exactly the same interface as the module sets but with a defined representation.
