 dedup only handles a single file at a time, so using tar is advised.
 To deduplicate a directory tree invoke dup-pack(1) as follows:
 
-    tar -c ~/dir | dup-pack -r repo foo
+    tar -cf - ~/dir | dup-pack -r repo foo
 
 This will create a new snapshot called foo under repo/archive/.
 
 To extract the snapshot:
 
-    dup-unpack -r repo foo | tar -x
+    dup-unpack -r repo foo | tar -xf -
