       The GRASS program _v_._a_r_e_a first displays the selected  vec-
       tor  file.   Then  user can select area on map by clicking
       with mouse within the desired area. Selected area will  be
       highlighted in selected color on graphics display. On reg-
       ular screen area information will be displayed, in  square
       meters,	hectares, acres, and square miles, Perimeter mea-
       surements, in meters, feet, and miles, are also displayed.


       User  can  repeatedly  select areas for analysis, one at a
       time.

   FFllaagg::
       --ff     Fill selected area with selected color on  graphics
	      display,	rather	than  simply  outlining it in the
	      _h_i_g_h_l_i_g_h_t color.

       mmaapp==_n_a_m_e
	      Name of the vector map layer to be displayed.

       ccoolloorr==_n_a_m_e
	      Color in which perimeter will be highlighted.
	      Default: red



       If the user simply types vv..aarreeaa without specifying program
       arguments on the command line, the program will prompt the
       user for the name of a map. Then the  user  is  given  the
       option  of specifying a highlight color, and then, whether
       or not the display of selected area(s) is  to  be  filled,
       rather than merely outlined, with the highlight color.
