 *
 * The only correct use of this class is to declare a global instance of it
 * (or an instance local to the main function) and pass pointers to the
 * instance to the methods that require such a parameter.  The instance can be
 * used for multiple registrations and the memory it uses will be freed at the
 * end of execution.  Any other use (like creating an instance local to a
 * function and using that) may cause memory leaks or errors (if the instance
 * is destroyed too early).
