       The GRASS program _v_._a_r_e_a first displays the selected vector 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  regular  screen  area  information  will be displayed, in
       square meters, hectares, acres, and square  miles,  Perimeter  measure-
       ments, 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.


   PPaarraammeetteerrss::
       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.
