 Hi,

 fwiw, where modules have grown to contain many such flags often the basic
 answer is to replace the flags with a single option=string with a drop
 down menu containing the mutually exclusive possibilities. Radio buttons
 shouldn't be needed when we have `opt->options = "";` and
 `opt->descriptions = "";`.

 that doesn't cover "multi-mode" modules, but for my 2c I'd consider those
 by definition to be arbitrarily complicated special cases and leave the
 error checking to the programmer not the parser.


 regards,
 Hamish
