class CircleTool from BRepMesh 

  ---Purpose: Create sort   and  destroy the  circles    used in
  --          triangulation.

  uses    Boolean from Standard,
          Integer from Standard,
          Real from Standard,
          XY from gp,
          Circ2d from gp,
          ListOfInteger from BRepMesh,
          CellFilter from BRepMesh,
          CircleInspector from BRepMesh,
          BaseAllocator from BRepMesh

  is      Create (theAlloc : in BaseAllocator from BRepMesh)
          returns CircleTool from BRepMesh;

             --          of  the occuped  space and  an  evaluation of  the
             --          number of circles.
