Description-en: Modular Printed Circuit Board layout tool
 pcb-rnd is a highly modular PCB (Printed Circuit Board) layout tool
 with a rich set of plugins for communicating with various external
 design tools and other EDA/CAD packages.
 .
 Feature highlights:
   - subcircuits, pad stacks
   - flexible footprint model; unrestricted pad shapes
   - arbitrary copper, silk, paste and soldermask objects
   - sophisticated, flexible layer model
   - flexible/universal polygon model
   - any object, even polygons, can have a clearance within a polygon
   - advanced mil and mm grid, with support for mixed unit design
   - strong CLI support
   - static footprints and parametric (generated) footprints
   - query language for advanced search & select
   - layout optimizers such as teardrops and a trace puller
   - footprint library from local file systems, HTTP and board files
   - netlist management: imported and as-built; back annotation
   - design rule checker
