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