Hi Ingo, thank you very much for explaining this in detail and giving a lot of additional information. I need to save this mail for possible later reference in similar cases.
That author names need to stay forever in a file is a matter of course also without knowlegde of copyright laws. Ok, now I know additionally that copyright notes need to stay literally (including possible typos ;). Since the file has no licence the header is of course left as it is (fortunately--else I had no idea how to implement these simple macros...). Carsten
