Hello!

I use some calc in my org document:

#+begin_SRC calc :var x=3D5 :var y=3D2 :exports both
  2 + a * x ** y
#+end_SRC=20

When I export this to LaTeX the listings package complains about an =
unknown language calc.

To fix this I simply define a language:

#+LATEX_HEADER: \usepackage{listings}
#+LATEX_HEADER: \lstdefinelanguage{calc}{morekeywords=3D{}}

Is this the correct way to do this?
Should this be added to the documentation?

Regards Axel=
