History
Werner Almesberger 1a790af50f atben: further crystal and RF ground cleanup 
- atben.brd: made ground zones go all the way around the board corner
- atben.brd: added one more via to crystal ground
- atben.brd: don't let crystal ground zone crawl under chip corner
- atben.brd: don't let RF ground zone crawl under chip corner

PCB manufacturing:

- do not print PCB edges on front/back copper
- do not print component values on silk screen
- note that the transceiver is "upside down"
- the center (!) of the board edge line marks the true board edge, e.g.,

                             Edge line (5 mil)
