       vv..cciirrccllee   -  Creates  a  vector file which consists of circle(s) which
       uses each point in a "site_lists" file as  the  center  of  those  cir-
       cle(s).

       "v.circle" will create "polygon" circle(s) around points read  from  an
       existing "site_lists" file.  The "site_lists" point(s) will be the cen-
       ter(s) for those circle(s) with one  circle  created  per  point.   The
       "polygon"  circle(s)  will  be  written	to a binary vector file.  Each
       "polygon" circle will have 361 points with each point on the circumfer-
       ence of the circle representing 1 degree of arc.

       rraaddiiuuss Radius of circle(s) with "site_lists" point(s) as center(s).  If
	      radius selected then area values are not used for  computations.
	      If  both	radius	and  area selected, then radius has precedence
	      over area.
	      default: 0.0



       rraaddiiuuss__uuoomm
	      Radius unit of measure,  ie. (m)meters,  ft(feet),  (mi)miles.
	      default: m



       aarreeaa   Area of circle(s) with "site_lists" point(s) as  center(s).   If
	      area  selected then radius values are not used for computations.
	      default: 0.0



       aarreeaa__uuoomm
	      Area unit  of  measure,	ie.  sqm(square  meters),   ac(acres),
	      sqmi(square miles),  hec(hectares).
	      default: sqm
