title: Creating multiple log files of different content with log4j
body: <p>Is there a way to configure log4j so that it outputs different levels of logging to different appenders?</p>
  <p>I'm trying to set up multiple log files.  The main log file would catch all INFO and above messages for all classes.  (In development, it would catch all DEBUG and above messages, and TRACE for specific classes.)</p>
  <p>Then, I would like to have a separate log file.  That log file would catch all DEBUG messages for a specific subset of classes, and ignore all messages for any other class.</p>
  <p>Is there a way to get what I'm after?</p>
