PCB is an interactive printed circuit board editor for the X11 window system.
PCB includes a rats nest feature, design rule checking, and can provide
industry standard RS-274-X (Gerber), NC drill, and centroid data (X-Y data)
output for use in the board fabrication and assembly process.  PCB offers high
end features such as an autorouter and trace optimizer which can tremendously
reduce layout time.
