Please correct me if I am wrong on this, but I believe the problem is due to 
the fact that the date/time format is customizable in the log file name. This 
makes it difficult to determine by name which log files to remove. Now, if one 
assumes that the date/time format used is sortable in a strictly-increasing 
manner (such as somelogfilenameYYYYMMDD.someextension) and no other variances 
exist in the filename format, then one can write a simple algorithm for the 
rolling file appender file cleanup part. But this imposes a hidden limitation 
based on an assumed naming convention.
