+/**
+ * This is a very simple filter based on string matching.
+ *
+ * <p>The filter admits two options <b>StringToMatch</b> and
+ * <b>AcceptOnMatch</b>. If there is a match between the value of the
+ * StringToMatch option and the message of the {@link org.apache.log4j.spi.LoggingEvent},
+ * then the {@link #decide(LoggingEvent)} method returns {@link org.apache.log4j.spi.Filter#ACCEPT} if
+ * the <b>AcceptOnMatch</b> option value is true, if it is false then
+ * {@link org.apache.log4j.spi.Filter#DENY} is returned. If there is no match, {@link
+ * org.apache.log4j.spi.Filter#NEUTRAL} is returned.
