/**
 * <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.
