type t = string * Locator.t
type r = (int * (string * Coord.t)) list MC.t
val no : t
val filename : string Stdlib.ref
val debug : bool Stdlib.ref
val interval : < loc : Locator.t.. > -> < loc : Locator.t.. > -> t
val toText : t -> string
val unite : t -> t -> t
val toLineDir : t -> string -> string
val getSuccReloc : string -> r -> Coord.t -> r * string option * Coord.t
val stripLines : string -> r * string
val addFirst : r -> r
val printRelocs : r -> unit
val printReloc : string -> r -> Locator.t -> unit
works only before calling Locator.updateToString
