Unfortunately there's still a lot of work before Gtk2Hs is ready to be
cabalised. Cabal configurations is a major piece of the puzzle though.
But sadly there are too many other bits before Gtk2Hs would be a
suitable test case for configurations.
A cut down model of Gtk2Hs might work though, ie a bunch of .cabal files
modelling the various bits of Gtk2Hs, just without any of the actual

Many related to fps/bytestring being included in the base package or
