[Haskell-cafe] How to mark a package obsolete on Hackage?

How does one mark a package obsolete on Hackage? For example, monads-fd no longer appears on the main web page listing available packages, but it still exists on Hackage (but is marked obsolete [1]). I have several package that are similarly obsolete due to mtl2 and would like to flag them appropriately. Thanks, Geoff [1] http://hackage.haskell.org/package/monads-fd
