I seem to recall something about this being harder with tiny as it
removes things rather than just extending. But I can't put recall
exactly what the issue was (or if there was one). I shall try it this
way if you prefer this approach. I felt the .inc approach provided a
more explicit building block mechanism which seemed more intuitive and
less prone to accidental inclusion. But, I don't feel strongly one way
or the other.
