<P>
This class used to output log statements from within the log4j package.
<p>Log4j components cannot make log4j logging calls. However, it is
sometimes useful for the user to learn about what log4j is
doing. You can enable log4j internal logging by defining the
<b>log4j.configDebug</b> variable.
<p>All log4j internal debug calls go to <code>System.out</code>
where as internal error messages are sent to
<code>System.err</code>. All internal messages are prepended with
the string "log4j: ".
