patch applied (cabal): Add Text class for displaying and parsing values

Thu Mar 20 18:54:14 PDT 2008 Duncan Coutts * Add Text class for displaying and parsing values This is intended to replace all these showFoo read/parseFoo functions we have all over the place. It's like the Read/Show classes but uses a half decent parser and pretty printer: class Text a where disp :: a -> Doc parse :: ReadP a This patch just adds the class and an instance for Bool, replacing the parseBool function used in a few places.
