-// = 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.
