title: Filename with date in Log4j
body: <p>I'm trying to append the current date to the log4j log file.  So it would be something like this:</p>
  
  <p>myApp-2011-01-07.log</p>
  
  <p>The thing is that I do not want to use the DailyRollingFileAppender.  Reason is that there will be another script that runs daily that will backup everything in the logs folder.
  This is running under Tomcat5.5.</p>
  
  <p>Is this possible in log4j?</p>
