Description

Cabal often needs to do slightly different things on specific platforms. You probably know about the `os` however using that is very inconvenient because it is a string and different Haskell implementations do not agree on using the same strings for the same platforms! (In particular see the controversy over "windows" vs "ming32"). So to make it more consistent and easy to use we have an `OS` enumeration.
