Info trace.

type tag =
  1. | Msg of lazy_msg
    (*

    A simple message

    *)
  2. | Tactic of lazy_msg
    (*

    A tactic call

    *)
  3. | Dispatch
    (*

    A call to tclDISPATCH/tclEXTEND

    *)
  4. | DBranch
    (*

    A special marker to delimit individual branch of a dispatch.

    *)

The type of the tags for info.

type state = tag Trace.incr
type tree = tag Trace.forest
val print : Environ.env -> Evd.evar_map -> tree -> Pp.t
val collapse : int -> tree -> tree

collapse n t flattens the first n levels of Tactic in an info trace, effectively forgetting about the n top level of names (if there are fewer, the last name is kept).
