Hi Stefan,
I don't know if this has been answered yet, but is there any concept of optional/required options in the program option library?
No; the "required options" functionality was requested, though.
Currently, only "allowed options" can be defined, no?
I would be great if you could define different sets of required option groups (because it's possible that a+b _or_ a+c are required) and provide some validatation for that. Otherwise, you have to do that by hand again and again.
Can you give the specific use cases. I think that fully generic solution can be overly complex, and we can get away with some helper functions. Say, 'mutially_excluse_options' can check than only one option of a group is specified. - Volodya
