+ * Author: efi, Matthias Pospiech (matthias@pospiech.eu)
+ * Copyright: (c) 2006 efi, Matthias Pospiech (matthias@pospiech.eu), Nigel McNie (http://qbnz.com/highlighter)
+ * Release Version: 1.0.8.6
+ * 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
+ * -------------------------
