# ==== Purpose ====
#
# Set up circular cluster replication where each 
# cluster has two mysqlds and replication directions are 
# following:
#              1       2
#          master ---> slave  
#           /            \
#     cluster A        cluster B
#           \  3       4 /
#         master1 <--- slave1
#
# ==== Usage ====
#
