What does :scope "provided" mean? : <p>I've seen a lot of places where some dependencies in Clojure project are marked with <code>:scope "provided"</code> (<a href="https://github.com/funcool/cats/blob/d1b7f3d60c7791798182937c54cbafa4e81536d4/project.clj#L6-L12" rel="noreferrer">example</a>).</p>

<p>What does it mean?</p>
