Re: gEDA-user: More questions about pcb

[Anthony Shanks <yamazakir2@xxxxxxxxx>]

I have a question about this method, how do I make a outline layer
with either a hollow polygon or 4 lines to make an outline? I don't
see an option to make the polygons hollow nor can I seem to connect
lines to anything other than pads.
