Directory operations.
Existence and contents
val exists : Topkg.fpath -> bool Topkg.result

val must_exist : Topkg.fpath -> Topkg.fpath Topkg.result
must_exist dir is dir if file is a regular file in the
file system and an error otherwise. Symbolic links are followed.
val contents : ?dotfiles:bool -> ?rel:bool -> Topkg.fpath -> Topkg.fpath list Topkg.result
contents ~dotfiles ~rel dir is the list of directories and filse
in dir. If rel is true (defaults to false) the resulting
paths are relative to dir, otherwise they have dir prepended.

current () is the current working directory.
val set_current : Topkg.fpath -> unit Topkg.result
set_current dir sets the current working directory to dir.
val with_current : Topkg.fpath -> ('a -> 'b) -> 'a -> 'b Topkg.result
