--I've always had trouble understanding the function of the 'edge2' 
flag. The geda wiki (2007 edition) says that for pads it means that the 
side in question is close to the edge. What edge?

Also, what is the significance of "EP" above? It occupies the slot 
reserved for the pin number if I read the syntax correctly. It cannot be 
anything because the netlist will reference it—or am I wrong?
