I like this approach and it would be nice if you can have a standard
"none" option, rendered in the dialog consistently "none" with text
"none of the above", but translated to ${GROUPNAME}_NONE for the port
and optionsfile. The group should be indented so one sees what "of the
above" applies to.
So the definition would look like:
OPTIONS_NONEORONE= EXAMPLE
OPTIONS_NONEORONE_EXAMPLE= BLONDE BRUNETTE

And the port's test would be:
.if ${OPTIONS:MEXAMPLE_NONE}
# yay, no work for me
.else
# crap which one he pick
.endif
