package StdPrs
    	---Purpose: The StdPrs package provides standard display tools
	-- for specific geometries and topologies whereas
	-- Prs3d provides those for generic objects. Among
	-- these classes are definitions of the display of the
	-- specific geometry or topology in various display
	-- modes such as wireframe, shading or hidden line removal mode.
