Ok. Now, I am at least able to get the pdf. Hooray! :)

#+title: Temp
#+LATEX_COMPILER: lualatex
#+LANGUAGE: he
#+LaTeX_Header: \usepackage[AUTO]{polyglossia}
#+LaTeX_Header: \setmainfont{FreeSerif}

\begin{equation}
f(x) = \frac{8}{7}
\end{equation}

#+begin_src python :exports code
for i in range(3):
    print("hello")
#+end_src

However, the PDF (see the attached) is erroneous:
1. Title "Temp" is written RTL
2. Year and date (numbers!) are written RTL
3. The python code is written RTL!!

Just the equation is rendered LTR as expected and the ordinary Hebrew
text is rendered RTL.

I hope that it can be implemented some day.
For now, we should detail important things, like setting suitable font,
in the manual.
