         * <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>&lt;?xml version="1.0" encoding="UTF-8" ?>
        &lt;!DOCTYPE log4j:configuration>

        &lt;log4j:configuration debug="true">

          &lt;appender name="ROLL" class="org.apache.log4j.rolling.RollingFileAppender">
            <b>&lt;rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
              &lt;param name="FileNamePattern" value="/wombat/foo.%d{yyyy-MM}.gz"/>
            &lt;/rollingPolicy></b>

            &lt;layout class="org.apache.log4j.PatternLayout">
              &lt;param name="ConversionPattern" value="%c{1} - %m%n"/>
            &lt;/layout>
          &lt;/appender>

          &lt;root">
            &lt;appender-ref ref="ROLL"/>
          &lt;/root>

        &lt;/log4j:configuration>
        </pre>

         *<p>This configuration file specifies a monthly rollover schedule including
         * automatic compression of the archived files. See
         * {@link TimeBasedRollingPolicy} for more details.
