1(** Configuration of the opam hooks (the three wrapper fields in
2 [~/.opam/config]). Changes are applied with the user's own [opam option],
3 never by writing the config file directly, so the file always matches the
4 opam version that owns it. *)

6val fields : exe:string -> (string * string * string) list
7(** The wrapper fields, the command to append to each, and a substring
8 identifying our command if already present. The per-package hooks are plain
9 coreutils ([mkdir]/[touch]/[rm]) so they work without odd installed;
10 only the post-session worker invokes the binary at [exe]. *)

12val print : exe:string -> unit
13(** Print the [opam option] invocations that {!apply} would run. *)

15val apply : exe:string -> (unit, [ `Msg of string ]) result
16(** Run them, skipping any field that already mentions [exe]. *)
