I just enabled spell check in vim. I like it and I know how to use it.
However, I would really like a project or even file specific spellfile as my list of accepted words. That way I can keep project (like thesis) specific words from being recognized in other projects.
When I open a Latex file in vim, I want vim to detect a particular spellfile in the Latex's file directory and load it. How can I achieve that?
