+/* cfgtok.c - helper class to tokenize an input stream - which surprisingly
+ * currently does not work with streams but with string. But that will
+ * probably change over time ;) This class was originally written to support
+ * the expression module but may evolve when (if) the expression module is
+ * expanded (or aggregated) by a full-fledged ctoken based config parser.
+ * Obviously, this class is used together with config files and not any other
+ * parse function.
