If you have a problem, for which you think there *should* be a Haskell library, please add it to this page:
I have misplaced my haskellwiki login right now, but...

Is System.Cmd.Utils in a position to be moved into base alongside System.Cmd and System.Process? It seems quite fundamental for getting work done quickly for script-like haskell programs. -- Don
