The behavior of o.a.l.rolling.RollingFileAppender is customizable by  
replacing the triggering policy and rolling policy objects.  Those  
are the anticipated extension points.  Please explain what type of  
behavior change you are trying to achieve.  If they can't be  
accomplished through the either the triggering policy or rolling  
policy, then we can consider modifying TriggeringPolicy or  
RollingPolicy, provide yet another extension point or (unlikely)  
removing the final keyword.

For background on why final is our friend, see items 14 and 15 in  
"Effective Java".
