findPlanJson :: FilePath -> IO FilePath

findProjectRoot :: FilePath -> IO (Maybe FilePath)

Find project root relative to a directory, this emulates cabal's current heuristic, but is slightly more liberal. If no cabal.project is found, cabal-install looks for *.cabal files in the specified directory only. This function also considers *.cabal files in directories higher up in the hierarchy.
