Re: [Caml-list] howto: recursively iterate over filesystem

[Fabrice Le Fessant <fabrice@lefessant.net>]

let rec iter_dir f dirname =
   let files = Sys.readdir dirname in
   Array.iter (fun file ->
      let file = Filename.concat dirname file in
      (f file : unit);
      if Sys.is_directory file then iter_dir f file
  ) files

?
