+Following are examples of running js_objgc.d.
+
+This script reports on the garbage collection of Java objects. That is it
+will keep track of when resources are allocated to an object, and when
+resources are freed from an object. It is useful for providing information on
+when garbage collection is not working correctly, as this can cause the
+browser to have a memory leak.
+
+We trace object creation (+1) and destruction (-1), and provide a summary
+each second of the running tally of the object class and originating filename.
+
+Here we can see it running on Code/JavaScript/func_clock.html
+
+# js_objgc.d
+Tracing... Hit Ctrl-C to end.

+^C
+
+Just after time 23:00:10, garbage collection fired cleaning up many objects.
+The final output shows a much reduced object count including a negative
+count for objects created before this script was tracing.
+
+If over the period of several minutes an object type is still steadily
+increasing, then that would be of interest. Be patient, depending on the rate
+of object creation it can take over ten minutes for garbage collect to kick in.
