Wheel structure (3/3)


        $ pip install pyside6  # still does the job!
        # shiboken6, pyside6-essentials, pyside6-addons
        # will be installed
        

        $ pip install pyside6-essentials  # is valid as well
        # shiboken6, pyside6-essentials
        # will be installed

Also the build internals!
