 *   This program tests the <ACE_Log_Msg> class in various ways and
 *   also illustrates many of the features of the <ACE_Log_Msg> For
 *   instance, this program tests the <ACE_Log_Msg> abstraction wrt
 *   writing to stderr and to a file.  It also tests writing to user
 *   defined callback objects.
