    start
        partition allmystuff {
            if(source newer that target?) then
                :Convert Source to Target;
            else (no)
            endif

            partition #0000ff repeat {
                if(source newer that target?) then
                    :Convert Source to Target;
                else (no)
                endif
            }
        }
