[csw-maintainers] how to express dependencies on alternatives?

Others have answered with the technicalities and I think they're
on the money.  I'll try to provide a usable workaround...

How about having CSWemacs that is a dummy package that depends only on
your preferred (or your view of the emacs users consensus) on which
version (x11, gtk or nox) people want.

Then, all of the packages delivering the real editor would be uniquely
named with -x11, -gtk and -nox.  The alternatives would be handled
directly within the real packages but things like auctex can still
have a generic dependency.

HTH.
