-    for <tt>hudson.model.Hudson</tt> or its descendants with the log level
-    info or above will show up in this log recorder, unless a more specific
-    logger with higher log level is also specific.
+    <tt>jenkins.model</tt> and <tt>INFO</tt> then any events triggered
+    for <tt>jenkins.model</tt> or its descendents (e.g.
+    <tt>jenkins.model.Jenkins</tt>) with the log level INFO or above will
+    show up in this log recorder.
 
     <p>
