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