     * (2) Since the wrapper class is generic, we have to pass in

     * VM properties rather than hacking up the arguments.  
     * <p>todo: relies on name/value of property "taskdef.jar"
     *    to add jar with wrapper to invoking classpath.
     * <p>
     * It is beneficial for another reason:
     * (3) The wrapper class can be asked to test-load all classes
     *     in a classes dir, by setting a VM property.  This class
     *     sets up the property if the value is defined using
     *     <code>setClassesDir(String)</code>
     * <p>todo: if more tunnelling, generalize and parse.
