Subj.

Thanks!

Argh parses whatever arguments are provided. It’s up to the user to decide what they mean and how they are used. It is not designed to a-priori limit the acceptable values. One way you may achieve what you want is to (externally) iterate over all the given flags and parameters and check if they belong to your user defined “known” set. If not issue your help message.
