In pseudo-code I'd like to do the following in my org-mode file:
#+BEGIN_src python
[[./a_python_script_whose_contents_i_want_in_my_document.py]]
#+END_src
i.e. have the entire contents of a separate file be embedded in my org-mode document when I export it to latex.
How do I embed the contents of a separate file within an org-mode document, and have that content be formatted as source code when exporting?
