  11 This script will read a gschem schematic and attempt to
  12 extract the relative positions of the components in the schematic,
  13 and generate corresponding MOVE instructions for Eagle.  You will
  14 likely have to adjust XOFFSET, YOFFSET, XSCAL, and YSCALE at the
  15 top of the script to obtain usable positions.
