+<dd>Use a circular list of filenames without timestamps. This option overwrites 
+log files at startup and during rotation.  With -n 3, the series of log 
+files opened would be "logfile", "logfile.1", "logfile.2", then overwriting 
+"logfile". 
+<br/>
+When this program first opens "logfile", the file will only be truncated if <code>-t</code> is also provided. Every subsequent rotation will
+always begin with truncation of the target file.  For size based rotation without <code>-t</code> and existing log files in place,
+this option may result in unintuitive behavior such as initial log entries being sent to "logfile.1", and entries in "logfile.1" not being preserved
+even if later "logfile.n" have not yet been used.
