-Since Gerber is just an image format, this library does not attempt to identify nor infer anything about what the file represents (e.g. a copper layer, a silkscreen layer, etc.) It just takes in a Gerber and spits out an SVG. This converter uses RS-274X and strives to be true to the [latest format specification](http://www.ucamco.com/files/downloads/file/81/the_gerber_file_format_specification.pdf?d69271f6602e26ab2474ad625fe40c97).
