package HLRTopoBRep

	---Purpose: This     Package  provides  some       topological
	--          reconstruction services needed  by the Hidden Line
	--          Removal Algorithms   using OutLine  and    IsoLine
	--          facilities, applied  to an object represented by a
	--          BRep data structure.
