0039 The <font color=red>vstring destinations = </font> {"detailedInfo.txt", ... }
0040 parameter establishes one or more file (or ostream) destinations for the
0041 messages issued.  The destinations can be configured individually to establish
0042 filtering of messages.
0043
0044 <p>
0045 If messages are issued prior to the initiation of the MessageLogger service,
0046 the configuration of these destinations will not yet have occurred.  Such
0047 messages will be sent to cerr.
