Note: help and version output are generated by a naïve script which tries a few variants of
<command> --help, <command> -h etc. to find the command's help and version info.
Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.
gdbus (return code: 1)
help Shows this information
introspect Introspect a remote object
monitor Monitor a remote object
call Invoke a method on a remote object
emit Emit a signal
Use "gdbus COMMAND --help" to get help on each command.
