+Several plugins process data using external programs. You may have a look at:
+
+- [[plugins/teximg]] which calls LaTeX;
+- [[plugins/graphviz]] which calls graphviz;
+- [[plugins/contrib/pandoc]] which calls pandoc.
+
+The first and second plugins I mentionned create an image using an external
+tool, and integrate it in the page. It may be exactly what you want.
