+Note that if you set AppStdout and/or AppStderr, applications which attempt\r
+to read stdin will fail due to a combination of factors including the way I/O\r
+redirection is configured on Windows and how a console application starts in\r
+a service context.  NSSM can fake a stdin stream so that applications can\r

 They will be rotated regardless of whether NSSM would otherwise have appended\r

+NSSM can also rotate files which hit the configured size threshold while the\r
+service is running.  Additionally, you can trigger an on-demand rotation by\r
+running the command\r
+\r
+    nssm rotate <servicename>\r
+\r
+On-demand rotations will happen after the next line of data is read from\r
+the managed application, regardless of the value of AppRotateBytes. Be aware\r
+that if the application is not particularly verbose the rotation may not\r
+happen for some time.\r
+\r
+To enable online and on-demand rotation, 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
