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

	      not used for computations.
	      default: 0.0



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