  mirrors:
        # Worlds listed here have their settings mirrored in their children.
        # The first element 'world' is the main worlds name, and is the parent world.
        # subsequent elements 'world_nether' and 'world_the_end' are worlds which will use
        # the same user/groups files as the parent.
        # the element 'all_unnamed_worlds' specifies all worlds that aren't listed, and automatically mirrors them to it's parent.
        # Each child world can be configured to mirror the 'groups', 'users' or both files from its parent.
