title: When to use "chore" as type of commit message?
body: <p>What is the use of <code>chore</code> in <a href="http://seesparkbox.com/foundry/semantic_commit_messages" rel="noreferrer">semantic version control commit messages</a>? Other types like <strong>feat</strong> or <strong>fix</strong> are clear, but I don't know when to use &quot;chore&quot;.</p>
  <p>Can anyone provide a couple of examples of its use?</p>
  <p>Another maybe not related question: What's the proper type of commit messages for modifying files like <code>.gitignore</code>?</p>
