/**
 * Implementation of Jakarta Commons logging interface that logs using
 * {@link org.lockss.util.Logger}.  This is installed via the file
 * src/commons-logging.properties, which is copied to top level in the jar
 * by build.xml.  <p>Until Logger has been configured for the first time
 * (in order to set log levels), the initial log level for these logs is
 * "info", unless overridden by the system property
 * org.lockss.defaultCommonsLogLevel.  This is because HttpClient is used
 * to read the LOCKSS configuration from the property server, and an
 * initial level of debug (which we often use) causes excessive output
 * during startup.
