   AArrgguummeenntts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.
