+   * 3. Ideally, there should be one EXE that can either run as a
+   *    separate process (as now) or that can install and run itself
+   *    as an NT service.  I have no idea how hard this is.
+   *
+   * Notes about develiping NT services:
+   *
+   * 1. Don't count on your CWD. If an abolute path is not given, the
+   *    fopen() function goes wrong.
+   * 2. The parameters given to the nt_service_body() function differ
+   *    from those given to main() function.
