title: Current date in doxygen documentation C++ header
body: <p>I wonder if it is possible to use the current date when documenting a C++ function with doxygen. For example</p>
  
  <pre><code>/**
   * This function is really boring. Documentation generated on __DATE__ 
   */
  void f()
  {}
  </code></pre>
  
  <p>Is there such a command? The __ DATE __ C++ macro doesn't work as it is inside a comment, so the pre-processor does not expand it. I can use a LaTeX macro such as <code>\f$\mathrm{\today}\f$</code> but it looks ugly.</p>
