       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 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 Pervasives.compare x0 x1 with 0 -> Pervasives.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 Set.Make .

       module type S = sig end

       Output signature of the functor Set.Make .

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

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