-WARNING!
+Version 0.6.4
+-------------
 
-The command line arguments and the format of zap snapshot
-names changed in version 0.6.0! The name change means you

+The replication arguments have changed.  When one or more
+datasets and a destination are supplied, the destination now
+comes before the list of datasets.
+
+   zap rep|replicate [-dLSv] [dest [-r] dataset [[-r]
+   dataset]...].
+
+
+Version 0.6.0
+-------------
+
+The command line arguments have changed.  Run zap without
