 -D <br>
 Turn on debugging output.<p>

 -W classname <br>
 Specify the full class name of classifier to perform cross-validation
 selection on.<p>

 -X num <br>
 Number of folds used for cross validation (default 10). <p>

 -S seed <br>
 Random number seed (default 1).<p>

 -P "N 1 5 10" <br>
 Sets an optimisation parameter for the classifier with name -N,
 lower bound 1, upper bound 5, and 10 optimisation steps.
 The upper bound may be the character 'A' or 'I' to substitute 
 the number of attributes or instances in the training data,
 respectively.
 This parameter may be supplied more than once to optimise over
 several classifier options simultaneously. <p>

 Options after -- are passed to the designated sub-classifier. <p>
