 * The permission which the SecurityManager will check when code
 * that is running with a SecurityManager calls one of the logging
 * control methods (such as Logger.setLevel).
 * <p>
 * Currently there is only one named LoggingPermission.  This is "control"
 * and it grants the ability to control the logging configuration, for
 * example by adding or removing Handlers, by adding or removing Filters,
 * or by changing logging levels.
 * <p>
 * Programmers do not normally create LoggingPermission objects directly.
 * Instead they are created by the security policy code based on reading
 * the security policy file.
