Indeed, I think the main problem lies here; especially since we're now
providing more or less frictionless (i.e., no build script necessary)
stack support out of the box.  A `--file` option that only makes sense
in case of a specific setup would feel a bit unsatisfying (at least to
me).

Though, I would imagine something like this shouldn't be too difficult
to hack together via a shell-script wrapper.
