-/**
- * Text highlighter base class
- *
- * This class implements all functions necessary for highlighting,
- * but it does not contain highlighting rules. Actual highlighting is
- * done using a descendent of this class.
- *
- * One is not supposed to manually create descendent classes.
- * Instead, describe highlighting rules in XML format and
- * use {@link Text_Highlighter_Generator} to create descendent class.
- * Alternatively, an instance of a descendent class can be created
- * directly.
- *
- * Use {@link Text_Highlighter::factory()} to create an
- * object for particular language highlighter
- *
- * Usage example
- * <code>
- *require_once 'Text/Highlighter.php';
- *$hlSQL =& Text_Highlighter::factory('SQL',array('numbers'=>true));
- *echo $hlSQL->highlight('SELECT * FROM table a WHERE id = 12');
- * </code>
