Hello everyone,

I have a project which `src` directory looks like this:

```auto
src/
|
|__ foo/
|__ bar/
|__ dune

```

(`bar` and `foo` are different sub-directories).

Is it the right way to go to put `copy_files` stanzas in my `dune` file, like the following?

```auto
(copy_files# (files foo/*))
(copy_files# (files bar/*))

```

Consider using `(include_subdirs unqualified)` in your dune file.

If you prefer the manual control, `(copy_files foo/*)` is the right stanza.
