Message: | README-SMT: various small clarifications - atben/README-SMT, atusb/README-SMT: added "component to "orientation" - atben/README-SMT, atusb/README-SMT: added "drawings" to "footprint reference" - atben/README-SMT, atusb/README-SMT: mention once more that the automatic insertion file is for the front only |
