25  * This is another simple example of how to use the LogFactor5
26  * logging console.
27  *
28  * The LF5Appender is the primary class that enables logging to the
29  * LogFactor5 logging window. If the following line is added to a properties
30  * file, the LF5Appender will be appended to the root category when
31  * the properties file is loaded:
32  *
33  * log4j.appender.A1=org.apache.log4j.lf5.LF5Appender
34  *
35  * To make this example work, you must ensure that the example.properties file
36  * is in your classpath.You can then run the example at the command line.
