[O] how to replace includegraphics?

[edgar]

Hello dear list,

* Summary
I want to know if someone could tell me how to replace (the macro, 
function, string) includegraphics for something else when exporting to 
LaTeX. In my case, simplesvg.

* Why
I have my own version of the svg package (I only extracted bits and 
pieces from it long time ago), and I want to make clear for others who 
may use my files that I'm not using includesvg (I could just change the 
definition of simplesvg to includesvg).

* What I have tried
** Stealing from the webz
This does not work. I think that the list doesn't exist in org-mode 
anymore:
#+BEGIN_SRC emacs-lisp
  ;; Export svg (does not work)
  ;; 
https://lists.gnu.org/archive/html/emacs-orgmode/2013-08/msg00221.html
  ;; 
https://github.com/tsdye/tufte-org-mode/blob/master/ox-tufte-latex.el
  (defun my-svg-graphics (contents backend info)
    (when (eq backend 'latex)
      (replace-regexp-in-string 
"\\`\\\\includegraphics.+\\({.+\.svg}\\)"
                                "\\\\simplesvg\1" contents))
    )
  (add-to-list 'org-export-filter-link-functions 'my-svg-graphics)
#+END_SRC

** Looking into org (ox-latex.el)
I found this (around line 2375 in ox-latex.el):
#+BEGIN_SRC emacs-lisp
(when (equal filetype "svg")
  (setq image-code (replace-regexp-in-string "^\\\\includegraphics"
                                             "\\includesvg"
                                             image-code
                                             nil t))
  (setq image-code (replace-regexp-in-string "\\.svg}"
                                             "}"
                                             image-code
                                             nil t)))
#+END_SRC

I could just change the code here (simplesvg instead of includesvg), but 
before f\#\#cking up my system, I would like to know if there is another 
alternative.

Thanks, as always :D !
