_A_r_g_u_m_e_n_t_s_:

  states: logical flag: include mainland internal state
          boundaries?

   coast: logical flag: include coastline?

    xlim: optional limits for the x-axis (longitude).

    ylim: optional limits for the y-axis (latitude).  (N.B.
          all latitudes for Australia are south, and hence
          are NEGATIVE.)

     add: logical flag.  If TRUE, the plot is superimposed
          on an existing plot.  Otherwise, a new plot is
          generated.

      ar: aspect ratio: longitude to latitude.

     eps: If `sections' (q.v.) is specified explicitly, the
          plot is enlarged four ways by this amount
          (degrees).

sections: integer vector specifying which `sections' of the
          plot are to be included in the range calculation.
          The sections are as follows: 1-7, coastlines of
          WA(1), NT(2), QLD(3), NSW(4), VIC(5), TAS(6) and
          SA(7) respectively; sections 8-16 are internal
          mainland state boundaries: SA-WA(8), WA-NT(9), NT-
          SA(10), NT-QLD(11), QLD-SA(12), QLD-NSW(13), NSW-
          SA(14), NSW-VIC(15), VIC-SA(16).

 visible: integer vector specifying which of the sections
          are actually to appear on the plot.

     ...: optional arguments which will be passed through
          `lines'.

          Graphical parameters (see `par()') may also be
          supplied as arguments to this function.
