+If AppStdoutCopyAndTruncate or AppStdErrCopyAndTruncate are non-zero, the\r

+NSSM to rotate files which are held open by other processes, preventing the\r
+usual MoveFile() from succeeding.  Note that the copy process may take some\r
+time if the file is large, and will temporarily consume twice as much disk\r
+space as the original file.  Note also that applications reading the log file\r
+may not notice that the file size changed.  Using this option in conjunction\r
