_D_e_s_c_r_i_p_t_i_o_n:

     Plot the Australian coastline and states.

_U_s_a_g_e:

     oz(states = TRUE, coast = TRUE, xlim = c(113, 154),
        ylim = c(-44, -10), add = FALSE, ar = 1, eps = 0.25,
        sections = 1:16, visible, ...)

_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.

_E_x_a_m_p_l_e_s:

     oz()                    # the lot
     oz(states=FALSE)        # coastlines only
     oz(sections=6)          # Tasmania
     oz(sections=c(7,8,10,12,14,16))         # South Australia
     oz(sections=c(3,11:13), visible=c(3,13))# plot Queensland, but show just
                                             # coast and border with NSW.
