 * Release Version: 1.0.8.11
 * Date Started: 2006/09/23
 *
 * LaTeX language file for GeSHi.
 *
 * CHANGES
 * -------
 * 2008/08/18 (1.0.8.1)
 *  - Changes in color and some additional command recognition
 *  - No special Color for Brackets, it is only distracting
 *    if color should be reintroduced it should be less bright
 *  - Math color changed from green to violett, since green is now used for comments
 *  - Comments are now colored and the only green. The reason for coloring the comments
 *    is that often important information is in the comments und was merely unvisible before.
 *  - New Color for [Options]
 *  - color for labels not specialised anymore. It makes sence in large documents but less in
 *    small web examples.
 *  - \@keyword introduced
 *  - Fixed \& escaped ampersand
 * 2006/09/23 (1.0.0)
 *  -  First Release
 *
 * TODO
