Thanks, but it says "useless with gschem", whatever that means. In the 
telephone.sch file I could only see a mike and a speaker with coil, but 
no power pins.

In the end it's important that a decent power pin handling is inside the 
program itself, not something that must be handled by letting a command 
line routine run over some files.
