g.gnuplot usage

[Darrell McCauley]

Someone asked me recently about plotting contour maps with g.gnuplot.
I thought this might be good for the general public. The scripts,
r.to.gnuplot and v.to.gnuplot, are on pasture.ecn.purdue.edu
in pub/mccauley/grass.

> For FrameMaker output,           gnuplot> set term mif
> For gpic (groff),                gnuplot> set term gpic
> For more options,                gnuplot> set term
