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