FreeRouting is a routing software intended but not limited for Printed Circuit
Boards (PCB). By using the standard Specctra or Electra DSN interface it
works together with numerous CAD tools including the LayoutEditor, KiCad
and Eagle. It imports DSN-files generated by the Specctra interface and
exports Specctra session files. FreeRouting was developed in 2004 by Alfons
Wirtz. He stopped the development in 2008 and published the source code
under the GPL in 2014. From 2015 FreeRouting is included in the LayoutEditor
packages and its source code is maintained by its team.
