<p>
If function calls are traced, trace patterns must be added by clicking button
<em>Add Trace Pattern</em>. Select a module, function(s), and a match specification.
- If no functions are selected, all functions in the module are traced.

+ Trace patterns can also be added for traced messages. This is

A few basic match specifications are provided in the tool, and
you can provide your own match specifications. The syntax of match
specifications is described in the <seealso
