title: What does "rc" in matplotlib's rcParams stand for?
body: <p><code>matplotlibrc</code> configuration files are used to customize all kinds of properties in <code>matplotlib</code>. One can change the <code>rc</code> settings to customize the default parameters e.g:</p>
  <pre><code>matplotlib.rcParams['font.family'] = 'times new roman'
  </code></pre>
  <p><strong>... but what does &quot;<code>rc</code>&quot; stand for?</strong></p>
  <p>I can't find any explanation in <a href="https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.rc.html" rel="noreferrer">the docs</a></p>
