# Makefile for generating gerbers and pngs.
# Tested on Advanced Circuits barebones, should work for 33 each,

# Sept. 30, 2014 - use another kind of file extension scheme
# Oct. 13, 2014 - milling layer (GML)
# Apr. 16, 2015 - Export the drill file with 2:4 precision for Eagle-7.2. Device is EXCELLON_24.
# Apr. 28, 2016 - Support 4-layer boards. i.e. add L2(*.G1) and L3(*.G2)
#
# TODO
# Interesting bug, if there are no holes on the board, the script fails
# because no drd file is generated, so... I touch an empty drd file
# so the build doesn't fail. This is kinda a kluge...
#
# If there's no dimension layer, the build fails...
#
# I should add document export: sch, brd
