title: How can I get log4j to delete old rotating log files?
body: <p>How can I get log4j to delete old rotating log files?  I know I can set up automated jobs (cron for UNIX and scheduled task for Windows), but I want it cross platform, and I want it in our application's log configuration as a part of our application, rather than in separate code outside in OS specific scripting languages.  Our application is not written in OS scripting languages, and I don't want to do this part of it in them.</p>
