type mark =

| Mark_both
(*
Mark definitions used from both arguments
*)
| Mark_positive
(*
Mark definitions used from the positive (first) argument
*)
| Mark_negative
(*
Mark definitions used from the negative (second) argument
*)
| Mark_neither
(*
Do not mark definitions used from either argument
*)

Type describing which arguments of an inclusion to consider as used for the usage warnings. Mark_both is the default.
