62 % |\graphpaper|\oarg{N}\parg{X,Y}\parg{DX,DY}
63 % Makes a grid with left-hand corner at \parg{X,Y}, extending
64 % \parg{DX,DY} units in the X and Y directions, where the lines are
65 % \emph{N} units apart. Every fifth line is thick and is numbered.
66 % The default value of \emph{N} is 10.
67 % The arguments must all be integers.

71 % First, we define three counters. The first two are defined
72 % as raw TeX counters since multiplication and division must be
73 % performed in them.
