Hello, This one is quite new: tangling a code block in `latex' language now produces a file with a `.latex' extension, instead of the common `.tex' extension.
Example: --8<---------------cut here---------------start------------->8--- * Letter composition #+begin_src latex :noweb yes :tangle yes \documentclass{article} \usepackage[utf8x]{inputenc} \usepackage[T1]{fontenc} % ... #+end_src --8<---------------cut here---------------end--------------->8--- Best regards, Seb PS- Org-mode version 8.2.5e (release_8.2.5e-111-g72ad52) -- Sebastien Vauban
