#ryu

usage: ryu [-h] [--config-dir DIR] [--config-file PATH] [--version]

           [subcommand] ...

positional arguments:

  subcommand          [rpc-cli|run|of-config-cli]

  subcommand_args     subcommand specific arguments

optional arguments:

  -h, --help          show this help message and exit

  --config-dir DIR    Path to a config directory to pull *.conf files from.

                      This file set is sorted, so as to provide a predictable

                      parse order if individual options are over-ridden. The

                      set is parsed after the file(s) specified via previous

                      --config-file, arguments hence over-ridden options in

                      the directory take precedence.

  --config-file PATH  Path to a config file to use. Multiple config files can

                      be specified, with values in later files taking

                      precedence. The default files used are: None.

  --version           show program's version number and exit
