# Converts *.rep files to RS274X header format
# Works for the Xilinx ML300 artwork, allegedly created
# by some flavor of PADS
# http://www.xilinx.com/products/boards/ml300/docs/ML300cpu_gerber.zip

# To convert all the RS274D files in that .zip file to a form usable
# by gerbv-0.16,
# for f in *.pho; do (pads-d2x ${f%.pho}.rep; cat $f) >${f%.pho}.gerb; done
