+So far, we've only added extensions for the *Request Start* trace point, and
+adding extensions for other trace points is done in almost the exact same
+way.  The only difference is the interface which an extension is registered
+for.
+
+Here, we'll register the tracer component in the previous examples for the
+other trace points.
+
+    >>> site_manager.registerUtility(
+    ...     count_tracer,
+    ...     zc.zservertracelog.interfaces.ITraceRequestInputAcquired,
+    ...     'example.CountTracer')
+
+    >>> site_manager.registerUtility(
+    ...     count_tracer,
+    ...     zc.zservertracelog.interfaces.ITraceApplicationStart,
+    ...     'example.CountTracer')
+
+    >>> site_manager.registerUtility(
+    ...     count_tracer,
+    ...     zc.zservertracelog.interfaces.ITraceApplicationEnd,
+    ...     'example.CountTracer')
+
+    >>> site_manager.registerUtility(
+    ...     count_tracer,
+    ...     zc.zservertracelog.interfaces.ITraceRequestEnd,
+    ...     'example.CountTracer')
+
+Now, that extension is fired at every trace point.
