 <summary>
      <p><code>rotatelogs</code> is a simple program for use in
-     conjunction with Apache's piped logfile feature.  For example:</p>
-
-<example>
-     CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common
-</example>
-	 
-     <p>This creates the files /var/logs/logfile.nnnn where nnnn  is
-     the system time at which the log nominally starts (this time
-     will always be a multiple of the rotation time, so  you  can
-     synchronize cron scripts with it).  At the end of each rotation
-     time (here after 24 hours) a new log is started.</p>
-
-<example>
-     CustomLog "|bin/rotatelogs /var/logs/logfile 5M" common
-</example>
-
-     <p>This configuration will rotate the logfile whenever it reaches
-     a size of 5 megabytes.</p>
-
-<example>
-     ErrorLog "|bin/rotatelogs /var/logs/errorlog.%Y-%m-%d-%H_%M_%S 5M"
-</example>
-     <p>This configuration will rotate the error logfile whenever it
-     reaches a size of 5 megabytes, and the suffix to the logfile name
-     will be created of the form
-     <code>errorlog.YYYY-mm-dd-HH_MM_SS</code>.</p>
