    <!-- Appenders for running JUnit tests -->
    <!-- Using additivity="false" on the "test.org.prevayler"
         logger allows us to exclude the "root" logger levels and appenders 
         making this logger, essentially, the root for all test cases.
         So, leave this logger alone.  To add loggers so you can see logging
         output for JUnit testcases, use the following syntax:
         <logger name="test.org.prevayler.test">
             <level value="debug"/>
         </logger>
    -->

        <level value="off"/>
        <appender-ref ref="JUnitAppender"/>
    </logger>

    <!-- Note: This root logger will be inherited by all loggers unless you use additivity="false". -->
    <root>
        <level value="warn"/>
        <!--<appender-ref ref="A1"/>-->
        <appender-ref ref="A2"/>
