I would appreciate if somebody could give me some clue as to the 
translation of Gerber photoplotter formats. So far, I have deduced the
obvious:
XiimmmYiimmmDnn    move to position (ii.mmm,ii.mmm) and use aperture
                   nn (D01: open shutter, D02: close shutter, D03:
                   flash)
M02                concludes file
D10-D26,D70-D73    circular or rectangular shapes
*                  terminate record
G01                ?
G90                ?
G54                ?

Thanks.
