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