-This section updates the outdated [[https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-LaTeX.html#orgcc214c1][Worg: backend dependent execution]] example to
-Emacs-27.2 and Org-9.5.2.  It shows how to export [[https://en.wikipedia.org/wiki/PGF/TikZ][PGF/TikZ]] images to:
-1. [[https://en.wikipedia.org/wiki/PDF][PDF]] by embedding in [[https://www.latex-project.org/][LaTeX]].
-2. [[https://en.wikipedia.org/wiki/HTML][HTML]] by passing from [[https://www.latex-project.org/][LaTeX]] by [[https://en.wikipedia.org/wiki/PDF][PDF]] and to [[https://en.wikipedia.org/wiki/Scalable_Vector_Graphics][SVG]].
-Listing [[lst:backend-dependent-execution-update]] tangles to
-[[file:worg-backend-dependent-execution-update.org][worg-backend-dependent-execution-update.org]] as either a standalone example or an
-example for inclusion.  Finally, inclusion of
-[[file:worg-backend-dependent-execution-update.org][worg-backend-dependent-execution-update.org]] produces here the figure with the
-nodes 1, 2, 3, and 4:\\
-#+include: worg-backend-dependent-execution-update.org
-How to include such figures as floats remains an open question.
