   * This Log object should help to detect the usage of deprecated code.

   * for tag libraries. Thought the designer of a Tobago page cannot see
   * in his IDE that a tag or attribute is deprecated.
   * <p>
   * The Tobago Java code will log into this Log object, with
   * <dl>
   *   <dt><code>error</code></dt>
   *   <dd>when the code is deprecated with a loss of function, or</dd>
   *   <dt><code>warn</code></dt>
   *   <dd>when the code is deprecated, but still works.</dd>
   * </dl>
   * <p>
   * This Log category can be switched off, in production environment without
   * affecting the normal logging category.
