This package contains classes useful for working with Log4j in a container
environment where many applications need to share Log4j without stepping
on each other's logging configuration. Each of these classes implements
the RepositorySelector
interface. Only one class may be used
per instance of Log4j. The container normally sets the repository selector,
but one may assign the selector themselves using the InitContextListener in
the org.apache.log4j.serlvet
package as well.
