     The meta-object system is a C++ extension that makes the language
-    better suited to true component GUI programming. Although
-    templates can be used to extend C++, the meta-object system
-    provides benefits using standard C++ that cannot be achieved with
-    templates; see \l{Why Doesn't Qt Use Templates for Signals and
-    Slots?}
