Log4j is fast and flexible framework for logging application debugging messages!
With log4j it is possible to enable logging at runtime without modifying the application binary. The log4j package is designed so that these statements can remain in shipped code without incurring a heavy performance cost. Logging behavior can be controlled by editing a configuration file, without touching the application binary.

We are exploring the creation of a new top-level Apache project, dedicated to logging. The immediate goal would be to bring the various related log4X projects together under one ASF umbrella. Another goal would be to support cross-language/cross-platform logging. The brain storming is happening at /LoggingApacheOrg..
