   7   * Release Version: 1.0.9.1
   8   * Date Started: 2006/09/23
   9   *
  10   * LaTeX language file for GeSHi.
  11   *
  12   * CHANGES
  13   * -------
  14   * 2008/08/18 (1.0.8.1)
  15   *  - Changes in color and some additional command recognition
  16   *  - No special Color for Brackets, it is only distracting
  17   *    if color should be reintroduced it should be less bright
  18   *  - Math color changed from green to violett, since green is now used for comments
  19   *  - Comments are now colored and the only green. The reason for coloring the comments
  20   *    is that often important information is in the comments und was merely unvisible before.
  21   *  - New Color for [Options]
  22   *  - color for labels not specialised anymore. It makes sence in large documents but less in
  23   *    small web examples.
  24   *  - \@keyword introduced
  25   *  - Fixed \& escaped ampersand
  26   * 2006/09/23 (1.0.0)
  27   *  -  First Release
