# tripleo.sh is a script to automate a TripleO setup. It's goals are to be
# used in aiding:
#
# - developer setups
# - CI
# - documentation generation (hopefully)
#
# It's not a new CLI, or end user facing wrapper around existing TripleO
# CLI's.
#
# tripleo.sh should never contain any "business" logic in it that is
# necessary for a successful deployment. It should instead just mirror the
# steps that we document for TripleO end users.

# set_ips: Whether or not to set l3 addresses on our logical l2 network.
#          This can be helpful for setting up routing tables.
# offset: starting value for gre tunnel key and the ip addr suffix
# The next two parameters are only used if set_ips is "True".
