The free schematic and PCB design tools at www.expresspcb.com produce an output with the .pcb extension. These tools seem to be Oriented for production at their site (only). Their .pcb file is not ASCII, and can be read with their free program. The free tools are a good way to create a captive audience. I don't think any other programs can use this data format.
