Implementation of commons-logging Log interface that delegates all logging calls to the Avalon logging abstraction: the Logger interface.

Jdk13LumberjackLogger	Implementation of the `org.apache.commons.logging.Log` interface that wraps the standard JDK logging mechanisms that are available in SourceForge's Lumberjack for JDKs prior to 1.4.
Jdk14Logger	Implementation of the `org.apache.commons.logging.Log` interface that wraps the standard JDK logging mechanisms that were introduced in the Merlin release (JDK 1.4).

Log	A simple logging interface abstracting logging APIs.
Log4JLogger	Implementation of `Log` that maps directly to a Logger for log4J version 1.2.
LogConfigurationException	An exception that is thrown only if a suitable `LogFactory` or `Log` instance cannot be created by the corresponding factory methods.
LogFactory	Factory for creating `Log` instances, with discovery and configuration features similar to that employed by standard Java APIs such as JAXP.
LogFactoryImpl	Concrete subclass of `LogFactory` that implements the following algorithm to dynamically select a logging implementation class to instantiate a wrapper for.
LogKitLogger	Implementation of `org.apache.commons.logging.Log` that wraps the avalon-logkit logging system.
LogSource	This class is deprecated. Use `LogFactory` instead - The default factory implementation performs exactly the same algorithm as this class did

Trivial implementation of Log that throws away all messages.

ServletContextCleaner	This class is capable of receiving notifications about the undeployment of a webapp, and responds by ensuring that commons-logging releases all memory associated with the undeployed webapp.
SimpleLog	Simple implementation of Log that sends all enabled log messages, for all defined loggers, to System.err.

Implementation of Hashtable that uses WeakReference's to hold its keys thus allowing them to be reclaimed by the garbage collector.
