   in the context of the current goal, as for instance in pcoq *)

val interp : Vernacexpr.vernac_expr -> unit

(** Print subgoals when the verbose flag is on.
    Meant to be used inside vernac commands from plugins. *)

val print_subgoals : unit -> unit

(** The printing of goals via [print_subgoals] or during
    [interp] can be controlled by the following flag.
    Used for instance by coqide, since it has its own
    goal-fetching mechanism. *)

val enable_goal_printing : bool ref

(** Should Qed try to display the proof script ?
    True by default, but false in ProofGeneral and coqIDE *)

val qed_display_script : bool ref

(** Prepare a "match" template for a given inductive type.
    For each branch of the match, we list the constructor name
    followed by enough pattern variables.
    [Not_found] is raised if the given string isn't the qualid of
    a known inductive type. *)
