cvs commit: avalon-excalibur/logger/src/java/org/apache/avalon/excalibur/logger DefaultLoggerManager.java
cziegeler 2003/03/06 03:26:10
Added: logger/src/java/org/apache/avalon/excalibur/logger
DefaultLoggerManager.java
Log:
A first try of a default logger manager that wrapps the real implementation (logkit, log4j). Does this make sense?

No problem with holding on - sorry, if I made any confusion; I just had

Are you trying to get this in pre Excalibur Logger release?
If so, I need you to get it ready really fast, or hold it till later.
