I wasn't too worried about the syntax since I can easily translate the files. I am worried about conventions. Are angles positive for CCW? To calculate angles on the bottom do you look through the board or flip the board? IPC-2581 references coordinates as positive x and positive y from a fiducial placed in the lower left corner on the top side of the board.
