Subject: WIP: kicad_gen is a util to generate schematic.h files from KiCAD
 netlist files. Current code contains a lexer and parser for KiCAD's netlist
 files and code to build a tree of the netlist which can be used for
 generation. Contains CMake code for integrating the generation into CMake
 too.
