ExtLib is LGPL without linking clauses ( same licence as Ocaml Standar
Libary ) and is then not compatible with GPL.
Is a multiset "common usage" enough to be included into ExtLib ?

From multiset.mli, I read:

(* original file set.ml[i] by Xavier Leroy *)
(* upgraded to multiset by S=E9bastien Briais *)
(* other contributors: Haakon Nilsen (union bug) *)

(*  This file is distributed under the terms of the GNU Library General *=
)
(*  Public License, with the special exception on linking described     *=
)
(*  LICENSE file which comes with OCaml distribution.                   *=
)


So, this is LGPL!

I'm sure there are at least two users (the author and myslef)... However
I think it's in general nice to have this kind of data structure... I
mean, it can be easily implemented in a number of way, but as it's
already there why reinvent the wheel ?

I agree that if included and not used by anybody it's waste of resources
and time to maintain it.

The same reasoning can be applied to a "set of sets" (or set of
multiset) data structure that can be easily implemented via functors
using the set module, but it would be nice to have it in a library...
