title: log4j-extras MaxBackupIndex or similar
body: <p>I'm using log4j-extras (1.2.17) <code>org.apache.log4j.rolling.RollingFileAppender</code> with a <code>org.apache.log4j.rolling.TimeBasedRollingPolicy</code> that rolls daily. Is there a similar property to maxBackupIndex in log4j's <code>org.apache.log4j.RollingFileAppender</code> (note the package difference) to limit the number of archived files? If not, is there another alternative for daily rolling with limited files?</p>
