Usage: munge [OPTIONS]

  -h, --help                Display this help message
  -V, --version             Display version information
  -n, --no-input            Encode a credential with an empty payload

The credential is written to stdout and can be piped into unmunge, locally
or on another host, to check that both ends share the same key:
  munge -n | unmunge
  munge -n | ssh node01 unmunge

(GreenRay AIO simulates the options listed above.)
