“pcb” is software to help you draw (“lay out”) the wires for a custom “printed wire board” (“PCB”).

<p>
The recommended way to install pcb is to install the complete gaf package. See <a href="http://geda.seul.org/wiki/geda:installation" class="wikilink1" title="geda:installation">installation</a>.

No. “Out-of-the-box”, pcb supports 16 copper layers and …

<p>
No. Lines on a layer with layer name <code>outline</code> will be interpreted as physical edges of the board.

<p>
Generally, you start with a schematic, run gsch2pcb to generate the netlist. See <a href="http://geda.seul.org/wiki/geda:faq-gsch2pcb" class="wikilink1" title="geda:faq-gsch2pcb">faq-gsch2pcb</a>. Then you might go through the tutorial <a href="geda_gsch2pcb_tutorial.html" class="wikilink1" title="geda:gsch2pcb_tutorial">gsch2pcb_tutorial</a>

Then you … Hey, did you know about the pcb manual, the <a href="geda_pcb_tips.html" class="wikilink1" title="geda:pcb_tips">pcb_tips</a>, and the <a href="geda_pcb-quick_reference.html" class="wikilink1" title="geda:pcb-quick_reference">pcb-quick_reference</a>?

See <a href="geda_pcb_footprints.html" class="wikilink1" title="geda:pcb_footprints">pcb_footprints</a>.

There are also some unofficial gEDA footprints at Open Circuits <a href="http://opencircuits.com/PCB_Footprints" class="urlextern" title="http://opencircuits.com/PCB_Footprints" rel="nofollow">http://opencircuits.com/PCB_Footprints</a>.

<p>
The application is a fairly old project, with roots way back in the era of <a href="http://en.wikipedia.org/wiki/Atari" class="urlextern" title="http://en.wikipedia.org/wiki/Atari" rel="nofollow">Atari home computers</a>. Its name has always been “pcb”. The current developers have no intention to break that tradition.
