What is the Microsoft ReferenceSource github repository for?
<p>Sorry for my complete ignorance on this matter. I know what <a href="http://referencesource.microsoft.com/" rel="nofollow">http://referencesource.microsoft.com/</a> aka <a href="http://sourceof.net" rel="nofollow">http://sourceof.net</a> is and I use it from time to time.</p>

<p>But I can't understand what this github repository at <a href="https://github.com/Microsoft/referencesource" rel="nofollow">https://github.com/Microsoft/referencesource</a> is for. I read its <strong>ReadMe.md</strong> file but I didn't understand anything.</p>

<p>Could you please explain what that repository holds and why would it be useful?</p>
