* <code>RollingFileAppender</code> extends {@link log4cxx::FileAppender} to backup the log files
* depending on {@link log4cxx::rolling::RollingPolicy RollingPolicy} and {@link log4cxx::rolling::TriggeringPolicy TriggeringPolicy}.
* <p>
* To be of any use, a <code>RollingFileAppender</code> instance must have both
* a <code>RollingPolicy</code> and a <code>TriggeringPolicy</code> set up.
* However, if its <code>RollingPolicy</code> also implements the
* <code>TriggeringPolicy</code> interface, then only the former needs to be
* set up. For example, {@link log4cxx::rolling::TimeBasedRollingPolicy TimeBasedRollingPolicy} acts both as a
* <code>RollingPolicy</code> and a <code>TriggeringPolicy</code>.
*
* <p><code>RollingFileAppender</code> can be configured programattically or
* using {@link log4cxx::xml::DOMConfigurator}. Here is a sample
* configration file:
<pre><?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration>
<log4j:configuration debug="true">
<appender name="ROLL" class="org.apache.log4j.rolling.RollingFileAppender">
<b><rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">

</layout>
</appender>
<root">
<appender-ref ref="ROLL"/>

*<p>This configuration file specifies a monthly rollover schedule including
* automatic compression of the archived files. See
