title: Are comment headers and footers in your code really necessary?
body: <p>Many corporate coding standards require a large comment header and footer in each and every file.  Something like:</p>
  
  <pre><code>// MyFile.cpp
  //
  //  Copyright (c) 200x Company ABC
  // 
  //  This file is a copyrighted... blah blah blah
  //
  
  &lt;... some code ...&gt;
  
  // Copyright (c) 200x Company ABC
  //
  //  Change history:
  //     1.0  -  Blah
  //     1.1  -  Blah, blah..
  </code></pre>
  
  <p>So, the question is - why do we need this?  Is this really necessary to claim copyright for the contents of the file, or is it a misguided practice that has become standard? 
  Anybody out there work for a company that does NOT require something like this?</p>
