public class Log
extends Object

Logging. This class provides a static logging interface. If an instance of the org.slf4j.Logger class is found on the classpath, the static log methods are directed to a slf4j logger for "org.mortbay.log". Otherwise the logs are directed to stderr. If the system property VERBOSE is set, then ignored exceptions are logged in detail.
