  --get <flag>       output the requested flag to stdout.
  --origin <flag>    output the origin of the flag to stdout:
                     value is one of vendor, system, user, env.
  --status           output a synopsis with all parameters affecting the
                     program behaviour, the resulting flags and their origin.
  --query            like --status, but in deb822 format.
  --query-features <area>
                     output the status of features for the given area.
  --list             output a list of the flags supported by the current vendor.
  --export=(sh|make|cmdline|configure)
                     output something convenient to import the compilation
                     flags in a shell script, in make, or in a command line.
  --dump             output all compilation flags with their values.
  --help             show this help message.
  --version          show the version.
