If you're going to have a compile-time choice between xaw and
motif, then it would be best to have two variants, one called xaw
and one called motif, which are marked as conflicting with one
another, and the port should select one of these by default, and
prevent the deselection of both variants simultaneously. This makes
it clear to the user that there is a choice between two
alternatives. There are several ports that exemplify this strategy
(pdftk's compiler selection, minivmac version 2's emulator
selection).
This is a matter of style, though.
I find it simpler to set things up like the above example instead
(this avoids an extra variant and avoids having to indicate
conflicting variants).
Well I just copied what pTex did for its xdvi toolkit into
texlive_base ... so if anyone feels like changing it, make sure you do
it in both places for consistency.
