+How to Unarchive an Archive
+---------------------------
+
+ Since all the fs shell commands in the archives work transparently,
+ unarchiving is just a matter of copying.
+
+ To unarchive sequentially:
+
+ `hdfs dfs -cp har:///user/zoo/foo.har/dir1 hdfs:/user/zoo/newdir`
+
+ To unarchive in parallel, use DistCp:
+
+ `hadoop distcp har:///user/zoo/foo.har/dir1 hdfs:/user/zoo/newdir`
+
