> I'm trying to build Yi (from the darcs repository) to take a look at it.  The README that comes with it says "it's a standard Cabal project so do what you normally do" (paraphrased slightly).  The problem is that I'm not a cabal user just yet and have no idea where to go from here.

The standard cabal usage is:
  runhaskell Setup.hs configure
  runhaskell Setup.hs build
  runhaskell Setup.hs install
