import oslo_config.cfg
# there are 3 ways to access the configuration.
#
# a. os_ken.cfg.CONF (used to register cli options)
# b. OSKenApp.CONF (preferred way for os_ken applications)
# c. oslo_config.cfg.CONF
#
# Currently a. and b. shares a single ConfigOpts instance.
# We intentionally avoid using c. for our options as a python program
# which embeds os_ken applications (eg. neutron agent) might want to put
# its own set of cli options into it, which can conflict with ours.
# (Currently there seems no conflict for the neutron agent. But who knows?)
# At some point later we might want to unshare a. and b. as well, in order
# to allow app-specific options.
CONF = oslo_config.cfg.ConfigOpts()
# re-export for convenience
