#
# Example file for building out a multi-node environment
#

# for this to work, you need to run the nodes in this order:

#
# 1. storage nodes
# 2. ringbuilder
# 3. run the storage nodes again
# 4. run the proxy
# 5. test that everything works!!
#
#
# This example file is almost the
# same as what I have been using
# to build swift in my environment (which is based on vagrant)
