The configuration file can specify options for a given destination, via a 
PSet with that destination as its name.  These options include setting 
thresholds for reacting to messages, setting limits of how many times this
destination will react to a messages of a given type (either ID or severity).
<p>
It is completely optional to have a PSet configuring a given destination.
For example, in this file, the cout destination is not further configured.
In that case, no filtering will be done for that destination -- all messages
will appear.
