title: Rolling logs by both size and time
body: <p>I use <code>RollingFileAppender</code> of <code>log4j 1.2.16</code>, which rolls log files, when they reach a certain size. Now I would like to roll log files daily <em>and</em> when they reach a certain size. Thus there will be one or more log files per day.</p>
  
  <p>For example,</p>
  
  <pre>myapp.log
  myapp-17.12.2013.log
  myapp-16.12.2012.log
  myapp-16.12.2012.1.log
  myapp-16.12.2012.2.log
  </pre>
  
  <p>Is there an off-the-shelf appender, which does it already? </p>
