package BRepAlgo

        ---Purpose: 
        -- The BRepAlgo package provides a full range of
        -- services to perform Old Boolean Operations in Open CASCADE. 
        --   Attention:
        -- The New Boolean Operation has replaced the Old
        -- Boolean Operations algorithm in the BrepAlgoAPI
        -- package in Open CASCADE.

        --          fact that no   geometric contols (intersection  of
        --          wires, pcurve validity) are performed.
