usage:
 $(basename $0) [-w] [-f] [node]

flags:
- -w : Waits for ONOS instance to reach run-level 100, i.e. to be fully started.
- -f : (Affects non-secure client only) - use bash's IFS expansion of positional parameters

options:
- [node] : the node to attach to

summary:
 ONOS remote command-line client.

 The -w flag depends on 'onos-wait-for-start'. If [node] is unspecified, \$OCI
 is used.
