Printing

putNormalLn :: MonadIO m => Verbosity -> String -> m ()

For output that one might want to use programmatically

Goes to stdout.

Can be suppressed with the --quiet flag.

putVerboseLn :: MonadIO m => Verbosity -> String -> m ()

For extra chatty messages

Goes to stderr so that the output that one might want to use programmatically can be captured separately.

Does not print unless the --verbose flag is used.
