It means you're just supposed to netlist it, not look at it. > In the > telephone.sch file I could only see a mike and a speaker with coil, > but > no power pins. Where did you expect to see the power pins? You don't want them on the main symbol, but you also don't want them on a separate symbol. This approach puts them in a text file, and gives you a way to merge such files into the net list. You've told us what you don't want. That doesn't tell us what you want. > > In the end it's important that a decent power pin handling is > inside the > program itself, Why? > not something that must be handled by letting a command > line routine run over some files.
