<p>
<b>GRAPH_PAPER</b>
is a FORTRAN90 library which
makes graph paper.
</p>
<p>
<b>GRAPH_PAPER</b> generates simple Encapsulated PostScript files
(EPS) representing several styles of graph paper.
</p>
<p>
When I manage to find a pad of printed graph paper, I use it all
up in a week. Right now, there are just a couple of options
involving simple plain grids, but more may come.
