This directory has two simple examples of the use of gnutex. The first
uses LaTeX. The file second demonstrates some pure gnuplot aspects,

! demo in latex form. The third demo, demo3, is almost the same as demo1
! except that it produces FIG output. demo3 uses eepic to output the FIG

xlabel, set ylabel, key, label, set style}, and {\tt set noclip}.
These are all described in the next section.
+ \subsection{Use with FIG}
+
+ Thanks to Micah Beck, author of Fig, Gnu\TeX\ now has a Fig driver.
+ Fig is an interactive drawing program that runs on Sun workstations
+ and under X windows. Files using the Fig language to describe the
+ pictures can be translated (with a suite of programs in the TransFig
+ package) to several other languages, such as PostScript, \TeX, and
+ \LaTeX.
+
+ If you choose the {\tt fig} terminal type in Gnu\TeX, a Fig format
+ file is produced that may be edited by Fig, translated by TransFig,
+ and printed or included in a \TeX\ or \LaTeX\ document. If you have
+ the EPIC or EEPIC macros, and your {\tt dvi} translator supports the
+ {\em tpic} \verb+\special+s, then you have the capability for very
+ good-quality output that draws curves with lines instead of dots.
+ The reader is referred to the Fig and EPIC documentation for further
+ information.
+
+ On the other hand, the Fig driver does not support user-defined
+ linestyles, nor the {\tt key} command.
+
+ The input file for Gnu\TeX\ should contain commands similar to these:
+ \singlespace
+ \begin{verbatim}
+ set terminal fig
+ set output "plot.fig"
+ set size 5,4
+ \end{verbatim}
+ \currentspace
+ Note that the output file has a {\tt .fig} extension. To obtain EEPIC
+ output from a command file (called, say, {\tt plot.gnu}), use the
+ shell commands
+ \singlespace
+ \begin{verbatim}
+ gnutex < plot.gnu
+ fig2epic plot.fig plot.tex
+ \end{verbatim}
+ \currentspace
+ Include the file plot.tex in your document as before, along with the
+ document style options {\tt [epic,eepic]}.

- Currently the plot is output as a \LaTeX\ picture environment. I plan

If sideways writing were possible, it might be fun to use for the
$y$-axis label. This is done by the Imagen driver. It would also be
nice to add different line styles (dotted, dashed, etc.).
And, since Gnu\TeX\ is derived from an old version of gnuplot, it
