+-- | One of the challenges of using the GHC API for external tooling
+-- is handling integration with Cabal. This library provides a simple
+-- interface for configuring GHC's 'DynFlags' as Cabal would have,
+-- allowing seamless tooling use on Cabal projects.
+--
+-- A typical usage might look like,
+--
+-- > import GHC
+-- > import qualified GHC.Paths
+-- > import qualified Distribution.Verbosity as Verbosity
+-- > import GHC.Cabal
+-- >
+-- > main = runGhc (Just GHC.Paths.libdir) $ do
+-- >     dflags <- GHC.getSessionDynFlags
+-- >     -- Use default DynFlags if we aren't in a Cabal project
+-- >     dflags' <- fromMaybe dflags <$> liftIO (initCabalDynFlags Verbosity.normal dflags)
+-- >     GHC.setSessionDynFlags dflags'
+-- >
+-- >     -- Standard GHC API usage goes here
