 * Description: Universal implementation of main, which may be included       *
 *     by any HEADAS binary. This code performs the necessary start-up        *
 *     operations, then calls the task's top-level function and finally       *
 *     performs the necessary shut-down operations.                           *
 *                                                                            *
 *    Language: C or C++                                                      *
