## Annotation Type Option

-     @Target(value=METHOD)
       @Retention(value=RUNTIME)
      public @interface Option

  Annotates a setter to be called with the value of a command line option. Setter have been preferred to field to allow validation.

  The cardinality of the option is detected from the single method parameter type: arrays, list and set can receive several values.
