The line endings problem, I had just started to forget about it, but reality got me back. There are still different OSes where each seems to know it better than the other one and has to have a different EOL. I only need to convert the line endings properly. Actually I don't want to it should be done for me, but this intelligence is still missing.
I like working with Python and I have even written it in Python (just because I had no online connection), but hey - why invent the wheel again? I thought I had unix2dos installed, but it seems not. And Fink doesn't know it either. But as usual there is a macosxhint for it, the program called flip, does it all in one. LineBreak Converter does even have a GUI.
