PCB Plugins (more detail coming eventually):

Everyone has a boxsym script. Mine is the result of starting to hack on djboxsym and then deciding to rewrite it. It's not finished, but there are some really good bits. Most interesting is probably the pseudo-PostScript gaf package that lets you render symbol primitives with translation, rotation and mirroring. Eventually all boxsyms could be written as layout modules for this program.


If you're considering gEDA/PCB, here are some sample projects I've done using the tools:
