   2 -----------------------------------------

   4 ovs-command-compgen.bash adds bash command-line completion support
   5 for ovs-appctl, ovs-dpctl, ovs-ofctl and ovsdb-tool commands.
   6
   7 Features:
   8 ---------
   9
  10    display available completion or complete on unfinished user input
  11    (long option, subcommand, and argument).
  12
  13    once the subcommand (e.g. ofproto/trace) has been given, the
  14    script will print the subcommand format.
  15
  16    the script can convert between keywords like 'bridge/port/interface/dp'
  17    and the available record in ovsdb.

  23    (dp, datapath, bridge, switch, port, interface, iface).
  24

  26    (e.g. ovsdb-tool create [db [schema]]).
  27
  28    does not support expansion on repeatitive argument
  29    (e.g. ovs-dpctl show [dp...]).
  30
  31    only support matching on long options, and only in the format
