    # Hack
    # The current directory ("src/util") is the top of the sys.path
    # And it will block the correct module finding especially when
util.groupUtils are called.
    # By making the current directory to the last item, we enable
calling util.groupUtils as
    # "src" will be found before the "src/util"
