 Unfortunately we cannot make this change yet without breaking the
 UserHooks api, which would break all custom <TT
>Setup.hs</TT

 moment we just have to live with this deficiency. If you're interested, see
 ticket #50.

 The point of this is that we do not allow extra valid values that would
 upset older Cabal versions that had a stricter parser however we cope with
 new values more gracefully so that we'll be able to introduce new value in
 future without breaking things so much.
