body: <p>What's happening in this code snippet ? </p>
  
  <pre><code>    RegexOptions options = RegexOptions.None;
      Regex regex = new Regex(@"[ ]{2,}", options);
      string outStr = regex.Replace(inStr, @" ");
  </code></pre>
  
  <p>What I am looking for is to replace any sequences of "white" spaces ( including TAB, CR, LF )   with a single space. </p>
