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.

# world2: (World2 would have it's own set of user and groups files)
# world3:
# - users (World3 would use the users.yml from world2, but it's own groups.yml)
# world4:
# - groups (World4 would use the groups.yml from world2, but it's own users.yml)
# world5:
# - world6 (this would cause world6 to mirror both files from world5)
