import oslo.config.cfg

# there are 3 ways to access the configuration.
#
#    a. ryu.cfg.CONF  (used to register cli options)
#    b. RyuApp.CONF  (preferred way for ryu applications)
#    c. oslo.config.cfg.CONF
#
# Currently all of above shares a single ConfigOpts instance.
# We will unshare c. (and stop using it) as soon as ofagent neutron agent
# is updated.
# We want to avoid using c. for our options as a python program which embeds
# ryu applications (eg. neutron agent) might want to 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.CONF

# re-export for convenience
