[O] How define a hook function for `org-babel-post-tangle-hook' for a single file?

[Grant Rettke]

Good morning,

* Desire

- I've got a file X
- I've got a hook function H
  - It does post-processing, copying the tangled results to different
directories
- I want to defined H in X
- I want H to be evaluated and run when X is tangled

* Research

- Emacs 25, Org Git current
- org-babel-post-tangle-hook
- File local variables and eval

* Question

What is the best way to do something like this?

Sincerely,

Grant Rettke
