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