/*! While we could easily add different input and output formats for the layerfiles
 *  to pcb2gcode, i've decided to ditch the importer/exporter scheme here.
 *  We'll very likely not encounter any drill files that gerbv can't read, and
 *  still rather likely never export to anything other than a ngc g-code file.
 *  Also, i'm lazy, and if I turn out to be wrong splitting the code won't be much effort anyway.
