       --aux-dir=DIRECTORY   Directory relative to --dir where auxiliary build

+                            modules are ignored.
       --avoid=MODULE        Avoid including the given MODULE. Useful if you
                             have code that provides equivalent functionality.
                             This option can be repeated.
