package IntPatch 

	---Purpose: Intersection between two patches.
	--          The class PatchIntersection implements the algorithmes
	--          of intersection.
	--          The classes IntPoint, PointOnDomain, Line, ILin, a.s.o...
	--          describe the results of the algorithmes.

        ---Level: Internal
        --
        -- All the methods of the classes of this package are Internal.
