title: How to download Chromium source code?
body: <p>I'd like to download some Chromium source code. In particular, the folder described at <a href="https://src.chromium.org/viewvc/chrome/trunk/src/chrome/common/extensions/docs/examples/extensions/email_this_page/">https://src.chromium.org/viewvc/chrome/trunk/src/chrome/common/extensions/docs/examples/extensions/email_this_page/</a></p>
  
  <p>How can I do that?</p>
  
  <p>I can't see the clone URL. I'm not even sure whether it's a git repo.</p>
