package BRepTopAdaptor 

	---Purpose: 
	--          
	--          
	--          *** Class2d    : Low level algorithm for 2d classification
	--          
	--          *** FClass2d   : 2d classification on a Face from TopoDS
	--                           A face is first loaded and then every 
	--                           classification is computed as a rejection.                        
	--                           (call BRepClass algorithms if necessary,
	--                           ie, when the rejection is not efficient)
	--                           
	--          *** TopolTool :  Several tools used by the intersection
	--                           algorithm and topology.
	--
