gnu­plot­tex – Embed Gnu­plot com­mands in LaTeX doc­u­ments

Gnu­plot code is ex­tracted from the doc­u­ment and writ­ten to .gnu­plot files. Then, if shell es­cape is en­abled, the graph files are au­to­mat­i­cally pro­cessed and con­verted to PostScript or PDF files, which will then be in­cluded. If shell es­cape is dis­abled, the user will have to man­u­ally run the files through gnu­plot and re-run the LaTeX job.
