Programmatically set TODO labels per file?

[Arthur Miller]

Hi all,

I have a simple question, but I wasn't able to find answer on the web,
so finally I'll try my luck here.

I know I can setq org-todo-keywords with a list '((sequence "TODO"
DONE")), as an example. But what variable is used for per-file keywords?
Once that are set with #+TODO: ... line?

I guess when org mode parses a file when starting up the mode, it has to
parse that line into some var, where do I find it?

Thanks in advance!

Best regards
