+
+There is a support for TikZ externalization. TikZ has been instucted to don't
+externalize pictures when tex4ht is used. It is necessary to  create the PDF
+images for TikZ pictures first, by compiling the document using a PDF producing
+engine. 
+
+The tex4ht configuration for PDF graphics is used for PDF inclusion, it will be
+converted to SVG by default.
