      Brett Scott and Denny Whitaker have written JMRI scripts to assist with programming these,
      and provided a nice writeup of how to use them. The
      writeup also covers how they document their layout, and discusses the pros and cons of
      several ways of connecting the Hare and Wabbit.
      You can download their scripts from
      the JMRI website, and it also available in the sample
      scripts directory in the JMRI downloads.
