-?,--help

  Extended usage information passed thru pager.
-> [rcfile], --save-opts[=rcfile]
  Save the option state to rcfile. The default is the last configuration file listed in the OPTION PRESETS section, below.
-< rcfile, --load-opts=rcfile,--no-load-opts
  Load options from rcfile. The no-load-opts form will disable the loading of earlier RC/INI files. --no-load-opts is handled early, out of order.
-v [{v|c|n}], --version[={v|c|n}]
  Output version of program and exit. The default mode is `v', a simple version. The `c' mode will print copyright information and `n' will print the full copyright notice.

### OPTION PRESETS

Any option that is not marked as not presettable may be preset by loading values from configuration ("RC" or ".INI") file(s) and values from environment variables named:

      NTP_KEYGEN_ or NTP_KEYGEN

The environmental presets take precedence (are processed later than) the configuration files. The homerc files are "$HOME", and ".". If any of these are directories, then the file .ntprc is searched for within those directories.
