+NSSM can also rotate files which hit the configured size threshold while the\r
+service is running.  To enable this feature, set AppRotateOnline to a non-zero\r
+value.\r
+\r
+Note that online rotation requires NSSM to intercept the application's I/O\r
+and create the output files on its behalf.  This is more complex and\r
+error-prone than simply redirecting the I/O streams before launching the\r
+application.  Therefore online rotation is not enabled by default.\r
