+<B>SYNOPSIS</B>
+  gsutil setacl [-R] file-or-canned_acl_name uri...
+
+
+<B>DESCRIPTION</B>
+  The setacl command allows you to set an Access Control List on one or
+  more buckets and objects. The simplest way to use it is to specify one of
+  the canned ACLs, e.g.,:
+
+    gsutil setacl private gs://bucket
+
+  or:
+
+    gsutil setacl public-read gs://bucket/object
+
+  See "gsutil help acls" for a list of all canned ACLs.
+
+  If you want to define more fine-grained control over your data, you can
+  retrieve an ACL using the getacl command (see "gsutil help getacl"),
+  save the output to a file, edit the file, and then use the gsutil setacl
+  command to set that ACL on the buckets and/or objects. For example:
+
+    gsutil getacl gs://bucket/file.txt > acl.txt
+    (Make changes to acl.txt such as adding an additional grant.)
+    gsutil setacl acl.txt gs://cats/file.txt
+
+  Note that you can set an ACL on multiple buckets or objects at once,
+  for example:
+
+    gsutil setacl acl.txt gs://bucket/*.jpg
+
+  If you have a large number of ACLs to update you might want to use the
+  gsutil -m option, to perform a parallel (multi-threaded/multi-processing)
+  update:
+
+    gsutil -m setacl acl.txt gs://bucket/*.jpg
+
+  Note that multi-threading/multi-processing is only done when the named URIs
+  refer to objects. gsutil -m setacl gs://bucket1 gs://bucket2 will run the
+  setacl operations sequentially.
+
+
+<B>OPTIONS</B>
+  -R, -r      Performs setacl request recursively, to all objects under the
+              specified URI.
+
+  -a          Performs setacl request on all versions / generations.
+
+  -v          Parses uris for version / generation numbers (only applicable in 
+              version-enabled buckets). For example:
+
+                gsutil setacl -v public-read gs://bucket/object#1348772910166013
+
+              Note that wildcards are not permitted while using this flag.
