  *
- * ${description}
+ * TTextHighlighter does syntax highlighting its body content, including
+ * static text and rendering results of child controls.
+ * You can set {@link setLanguage Language} to specify what kind of syntax
+ * the body content is. Currently, TTextHighlighter supports the following
+ * languages: 'php','prado','css','html','javascript' and 'xml', where 'prado'
+ * refers to PRADO template syntax. By setting {@link setShowLineNumbers ShowLineNumbers}
+ * to true, the highlighted result may be shown with line numbers.
