Exported functions
cabalSet returns a list of ghci commands (seperated by newlines) that :set the packageOpts of the current cabal project
Arguments
| :: FilePath | path to the .cabal file |
| -> PackageDescription | parsed package description |
| -> Maybe LocalBuildInfo | parsed build config |
| -> String | name of executable |
| -> Maybe [String] |
Build a list of ghci options needed to load files from a cabal project
Arguments
| :: FilePath | usually the current directory |
| -> FlagAssignment | list of cabal flag assignments |

Load the current cabal project file and parse it
Find a .cabal file in the path or any of it's parent directories
Arguments
| :: [String] | List of cabal flag arguments and executable name |
| -> (String -> IO a) | Error continuation. Recieves an error message. |
| -> ([String] -> IO a) | Success continuation. Recieves a list of ghci arguments. |
| -> IO a |
