+Gluster Unified File and Object Storage allows files and directories created
+via gluster-native/nfs mount to be accessed as containers and objects. It is
+a plugin for OpenStack Swift project.
+
+Install
+* Clone the swift repo from git://github.com/openstack/swift.git
+* Apply the swift.diff present in glusterfs.git/swift/1.4.8 to the swift repo.
+* Create a directory named "plugins" under swift.git/swift directory.
+* Copy the contents of glusterfs.git/swift/1.4.8/plugins/ under swift.git/swift/
+  except the conf directory.
+* Copy the contents of glusterfs.git/swift/1.4.5/plugins/conf under /etc/swift/.
+* Run python setup.py install
+
+Once this is done, you can access the GlusterFS volumes as Swift accounts.
+Add the Volume names with the user-name and its corresponding password to the
+/etc/swift/proxy-server.conf (follow the syntax used in the sample conf file).
+
+Command to start the servers
+  swift-init main start
+
+Command to stop the servers
+  swift-init main stop
