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
