23  * This class is a simple example of how use the LogMonitorAdapter to
24  * bypass the Log4JAppender and post LogRecords directly to the LogMonitor
25  * using customized LogLevels
26  *
27  * To make this example work, ensure that the lf5.jar and lf5-license.jar
28  * files are in your classpath, and then run the example at the command line.
