title: Set ASP.NET Bundling To Not Remove Third Party Copyrights
body: <p>I'm moving ASP.NET bundling into a site I have and I noticed that it is removing all comments from the code including copyright header comments (in CSS and JavaScript). This would be ok if it was my copyrights as I could just create my own <code>IBundleTransform</code> and add my copyright to the top, but it is not ideal to do this with third party copyrights.</p>
  
  <p>Are there any good ways to keep these copyright headers (or maybe a flag that I haven't fround in the MSDN documentation)? Thanks!</p>
