Ok. Consider a port that has a variant +with_rtf and, by your
request, also +without_rtf. The user specifies neither of these
variants. You say the default should be one or the other. Let's say
that the default is to include RTF support. So the +with_rtf variant
would do nothing different? Would contain no code at all? Doesn't
that seem weird?

However, variants like darwin_8 and macosx are auto-selected by the
MacPorts infrastructure without the need to specify them in the
You say it doesn't have to be the case that only these few variants
be useful globally. To you have a specific example of another kind of
variant that would be useful globally? I believe I saw that gentoo
has this concept too, and I wasn't sure how it was useful there either.
