Thanks so much. It sort of works but with a bit of work-around:
1) tangle works fine
2) for export, I had to move the
> ,#+MACRO: SEC_FOO
lines out of the code block. If I didn’t and tried to eval that block, I got
the error
No org-babel-execute function for org!
But I think this will do what I need. Of course emacs / org couldn’t have a
simple preproccessor-like macro :)
