22 /**
23  * This class is a simple example of how to use the LogFactor5 logging
24  * window.
25  *
26  * The LF5Appender is the primary class that enables logging to the
27  * LogFactor5 logging window. The simplest method of using this Appender
28  * is to add the following line to your log4j.properties file:
29  *
30  * log4j.appender.A1=org.apache.log4j.lf5.LF5Appender
31  *
32  * The log4j.properties file MUST be in you system classpath. If this file
33  * is in your system classpath, a static initializer in the Category class
34  * will load the file during class initialization. The LF5Appender will be
35  * added to the root category of the Category tree.
36  *
37  * Create a log4j.properties file and add this line to it, or add this line
38  * to your existing log4j.properties file. Run the example at the command line
39  * and explore the results!
