deferred class BooleanOperation from BRepAlgo inherits MakeShape from BRepBuilderAPI

    	---Purpose:  The abstract class BooleanOperation is the root
    	-- class of Boolean operations.
    	-- A BooleanOperation object stores the two shapes in
    	-- preparation for the Boolean operation specified in
    	-- one of the classes inheriting from this one. These include:
    	-- - Common
    	-- - Cut
    	-- - Fuse
    	-- - Section.
