This package allows you to include Gnuplot graphs in your LaTeX
documents. The gnuplot code is extracted from the document and
written to .gnuplot files. Then, if shell escape is used, the
graph files are automatically processed to graphics or LaTeX
code files which will then be included in the document. If
shell escape isn't used, the user will have to manually convert
the files by running gnuplot on the extracted .gnuplot files.
