  <p>I have a function which checks if a certain thing exists, and if not, creates it. What would be a good word for it? Right now I'm using "maintain", so the function is called <code>maintain_buffer_on_path</code>, but I think that "maintain" is misleading. Can you think of a better one-word name?</p>
