- * Constructor. Backward compatibility ( < PHP5 ).
- *
- * @param string $root Root directory where template files are.
- * @param bool $useIncludePath If it's true, it looks for template files in
- * PHP's include_path.
- * @param string $group Group of templates to use (a subdirectory in root).
+ * Returns a parsed template.
+ * This function parses a template $name in the $group (or the current group
+ * if it's null), replacing the variables specified by $vars. $vars can be a
+ * string (in which case it's replaced by the value $val) or an asociative
+ * array, where the keys are the variables to replace and the values are the
+ * text to put in the place of the variable.
