       Module Set
        : sig end

       Sets over ordered types.

       This module implements the set data structure, given a total ordering function over the set elements. All
       operations over sets are purely applicative (no side-effects).  The implementation uses  balanced  binary
       trees,  and is therefore reasonably efficient: insertion and membership take time logarithmic in the size
       of the set, for instance.

       The MoreLabels.Set.Make functor constructs implementations for any type, given a compare  function.   For
       instance:
              module IntPairs =
                struct
                  type t = int * int
                  let compare (x0,y0) (x1,y1) =
                    match Stdlib.compare x0 x1 with
                        0 -> Stdlib.compare y0 y1
                      | c -> c
                end

              module PairsSet = Set.Make(IntPairs)

              let m = PairsSet.(empty |> add (2,3) |> add (5,7) |> add (11,13))

       This creates a new module PairsSet , with a new type PairsSet.t of sets of int * int .

       module type OrderedType = sig end

       Input signature of the functor MoreLabels.Set.Make .

       module type S = sig end

       Output signature of the functor MoreLabels.Set.Make .

       module Make : (Ord : OrderedType) -> sig end

       Functor building an implementation of the set structure given a totally ordered type.
