Hello all,I think I'm missing something basic: I'd like to have something like this:#+begin_src python#+filename: foo.pyInstead of storing my Python code in the current org file, I would likeBabel to read foo.py and execute it, as if it was inside the .org file.The foo.py mentioned above is fairly large, and I would like the codeto be stored in a different file than my .org file, for brevity.Any ideas? I feel like I'm missing something obvious.Thanks,--Nate
