When we say '-n --iterations=N' in --help, this means that the program can be invoked with '-n N' or '--iterations=N' or '--iterations N'. (The short option is specified without the argument.) Here we tried to use '-p --order=path' to mean that the program can be invoked with '-p' or '--order=path', but that is incompatible with the established convention. Also, indicate that the arg to --cpu is optional.
