     22 # Script-specific args:
     23 #   --mode=[host|target]: Select between host or target bootclasspath (default target).
     24 #   --core-only:          Use only "core" bootclasspath (e.g. do not include framework).
     25 #   --show-commands:      Print the desugar command being executed.
     26 #   --help:               Print above list of args.
