      This is equivalent to decorating a function with :func:`option` with
      the following parameters::
  
          def callback(ctx, param, value):
              if not value:
                  ctx.abort()
  
          @click.command()
          @click.option('--yes', is_flag=True, callback=callback,
                        expose_value=False, prompt='Do you want to continue?')
          def dropdb():
              pass
