61 % |\graphpaper|\oarg{N}\parg{X,Y}\parg{DX,DY}
62 % Makes a grid with left-hand corner at \parg{X,Y}, extending
63 % \parg{DX,DY} units in the X and Y directions, where the lines are
64 % \emph{N} units apart. Every fifth line is thick and is numbered.
65 % The default value of \emph{N} is 10.
66 % The arguments must all be integers.

70 % First, we define three counters. The first two are defined
71 % as raw TeX counters since multiplication and division must be
72 % performed in them.
