+# Note for the reader:

+# This demo conveniently uses the same names for actions and for the container nodes
+# that hold each remapping button. This allow to get back to the button based simply
+# on the name of the corresponding action, but it might not be so simple in your project.
+#
+# A better approach for large-scale input remapping might be to do the connections between
+# buttons and wait_for_input through the code, passing as arguments both the name of the
+# action and the node, e.g.:
+# button.connect("pressed", self, "wait_for_input", [ button, action ])
