+// = DESCRIPTION
+//    This example illustrates how to use the ACE tracing feature and
+//    the ACE_TRACE macro.  It also shows the use of the ACE_Task_Base
+//    class running as an "active object".
+//
+//    When adding ACE tracing to an application one option is to add
+//
+//    #define ACE_NTRACE 0
+//
+//    in the line above #include "ace/Log_Msg.h".  That's the approach shown below.
+//
+//    Another option is to add this line in $ACE_ROOT/ace/config.h.
+//    Note, however, that if you add the line in config.h, you need to
+//    add it *after* you've built ACE, i.e., don't build ACE with it
+//    set to 0 as then you will get all the internal ACE_TRACE calls
+//    showing up as well!  In a nutshell, in this second option you
+//    do this:
+//
+//    1. Build ACE without tracing (i.e., don't #define ACE_NTRACE 0 in config.h)
+//    2. Add #define ACE_NTRACE 0 in config.h
+//    3. Build your app with tracing.
