+  Use this option to indicate which directories contain files that can be
+  changed by the modernizer. Inidividual files may be specified if desired.
+  Multiple paths can be specified as a comma-separated list. Sources mentioned
+  explicitly on the command line are always included so this option controls

+
+  Used with ``-include`` to provide finer control over which files and
