Ok, here's a half-hour hack that should serve as a starting point.
You need an installed ghc-2.10 (or modify the script). Install the
script as 'ghcmake', then go into a directory containing your Haskell
program (at least Main.{lhs,hs} must exist), and type 'ghcmake'. With
any luck, you'll get an executable called 'Main'.
Cheers,
Simon
