19# there are 3 ways to access the configuration.
20#
21#    a. ryu.cfg.CONF  (used to register cli options)
22#    b. RyuApp.CONF  (preferred way for ryu applications)
23#    c. oslo_config.cfg.CONF
24#
25# Currently a. and b. shares a single ConfigOpts instance.
26# We intentionally avoid using c. for our options as a python program
27# which embeds ryu applications (eg. neutron agent) might want to put
28# its own set of cli options into it, which can conflict with ours.
29# (Currently there seems no conflict for the neutron agent.  But who knows?)
30# At some point later we might want to unshare a. and b. as well, in order
31# to allow app-specific options.
