Comment (by Roland Haas):

I will have to write proper documentation still., which will document these,

I am be quite reluctant to add new options to the command line since it can easily become a mess. For more complex use cases, using it as a Python module and calling the POWER or Nakano routines directly is the preferred way of using it.

The thinking is that “module options” will be things that would be identical between simulations while function arguments are things that change from one simulation to the next.
