\multiput ¶Synopsis:
\multiput(x,y)(delta_x,delta_y){num-copies}{obj}
Copy obj a total of num-copies times, with an increment of delta_x,delta_y. The obj first appears at position (x,y), then at (x+\delta_x,y+\delta_y), and so on.
This draws a simple grid with every fifth line in bold (see also
\graphpaper).
