title: Get Apple clang version and corresponding upstream LLVM version
body: <p>I want to understand which version of clang Apple installed in my macbook, to see with c++11 and/or c++14 features are available.
  I typed this command:</p>
  
  <pre><code>clang --version
  
  //----response
  Apple LLVM version 7.0.0 (clang-700.1.76)     
  Target: x86_64-apple-darwin15.0.0    
  Thread model: posix
  </code></pre>
  
  <p>But I am not able to understand what <code>(clang-700.1.76)</code> mean.
  How can I convert this code to a clang version?</p>
