-# This controller (and respective route in the Spree engine)
-#   is only needed for the spree_paypal_express gem that redirects here explicitly.

-# According to the rails docs it would be possible to redirect
-#   to CheckoutController directly in the routes
-#   with a slash like "to: '/checkout#edit'", but it does not work in this case.
