+%description
+The Simple Logging Facade for Java or (SLF4J) is intended to serve
+as a simple facade for various logging APIs allowing to the end-user
+to plug in the desired implementation at deployment time. SLF4J also
+allows for a gradual migration path away from
+Jakarta Commons Logging (JCL).
+
+Logging API implementations can either choose to implement the
+SLF4J interfaces directly, e.g. NLOG4J or SimpleLogger. Alternatively,
+it is possible (and rather easy) to write SLF4J adapters for the given
+API implementation, e.g. Log4jLoggerAdapter or JDK14LoggerAdapter..
