+Controller class
+
+Provide the interface to the control channel to the switch under test.  
+
+Class inherits from thread so as to run in background allowing
+asynchronous callbacks (if needed, not required).  Also supports
+polling.
+
+The controller thread maintains a queue.  Incoming messages that
+are not handled by a callback function are placed in this queue for 
+poll calls.  
+
+Callbacks and polling support specifying the message type
+
+@todo Support transaction semantics via xid
+@todo Support select and listen on an administrative socket (or
+use a timeout to support clean shutdown).
+
+Currently only one connection is accepted during the life of
+the controller.   There seems
+to be no clean way to interrupt an accept call.  Using select that also listens
+on an administrative socket and can shut down the socket might work.

+
+ovs-ctl manages the initialization and execution of OVS instances as targets
+for OFTest execution. 
+
+
+-------------------------------------------------------------------------------
+INSTALLATION
+-------------------------------------------------------------------------------
+
+ovs-ctl requires OVS be built and installed on your local machine. 
+If you are new to OVS, the preferred method is:
+
+1. Download openvswitch-X.Y.Z from http://openvswitch.org/releases
+2. Untar, configure, build, and install openvswitch into a useful location:
+
+   # All OVS installations will go in to /opt/ovs:
+   > mkdir -p /opt/ovs
+   
+   # All OVS Source distributions will live in /opt/ovs/src:
+   > mkdir -p /opt/ovs/src
+
+   # Download and untar source for openvswitch 1.4.0:
+   > curl http://openvswitch.org/releases/openvswitch-1.4.0.tar.gz | tar -xzC /opt/ovs/src
+
+   # build and install:
+   > cd /opt/ovs/openvswitch-1.4.0
+   > ./configure --prefix=/opt/ovs/1.4.0 --with-linux=/lib/modules/`uname -r`/build
+   > make
+   > sudo make install
+
+   # Copy the OVS kernel module out of the build tree into the install tree:
+   > sudo cp /opt/ovs/src/openvswitch-1.4.0/datapath/linux/openvswitch_mod.ko /opt/ovs/1.4.0/sbin
+
+
+3. READ the comments and instructions in ovs-ctl-default.example.conf
+
+4. Copy ovs-ctl-default.example.conf from the local directory to /opt/ovs:
+   
+   > sudo cp ovs-ctl-default.example.conf /opt/ovs/ovs-ctl-default.conf
+
+5. Modify /opt/ovs/ovs-ctl-default.conf to match your existing installation(s). 
+   If you followed the directions and used the paths suggested in Step 2, then the default 
+   configuration file should work without modification. 
+   Otherwise, edit to point to your installation directorie(s). 
+
+
+
+-------------------------------------------------------------------------------
+EXAMPLE USAGE
+-------------------------------------------------------------------------------
+
+You can initialize and run your default configuration (as specified in the config files) as follows:
+
+> ./ovs-ctl
+
+You can stop a running configuration as follows:
+
+> ./ovs-ctl --kill
+
+You can initialize and run any configuration (as specified in the config files) as follows:
+
+> ./ovs-ctl --config 1.3.0
+> ./ovs-ctl --config 1.4.0
+> ./ovs-ctl --config MySomeOtherConfiguration
+
+You can output logging and verbose information with the --log and --verbose options. 
+
+By default, OVS is initialized with 4 veth ports. You can change this with the --port-count option. 
+
+
+
+CONFIG FILES
+------------
+
+The configuration file options are just convenient methods of storing values for the command line
+arguments. Every command line argument can be specified as a key in your configuration file. 
+
+You do not need a configuration file at all -- you can specify all required paths and values
+from the command line -- but this is not recommended for regular usage. 
+
+The precedence for these settings is in the following order:
+
+1. Command Line option, if specified, THEN
+2. The [ConfigName] section of all config files, both default, user, or command-line specified, THEN
+3. The [Defaults] section of all config files
+
+
+Note that you may have a section defined in the ovs-ctl-default.conf file, AND in your ~/.ovs-ctl file. 
+The settings will be merged together, with the values in ~/.ovs-ctl taking precedence:
+
+So, for example, you can have the local installation information for 1.4.0 specified in /opt/ovs/ovs-ctl-default.conf as follows:
+
+    [1.4.0]
+    # ovs-1.4.0, configured and built into /opt/ovs/1.4.0
+    # Can be selected with 'ovs-ctl.py --config 1.4.0'
+    ovs_src_dir:/opt/ovs/src/openvswitch-1.4.0
+    ovs_base_dir:/opt/ovs/1.4.0
+    ovs_runtime_dir:/var/run/ovs/1.4.0
+
+This can be used by everyone. 
+
+You can also have user-specific settings in ~/.ovs-ctl for your own execution:
+
+    [1.4.0]
+    # Put logfiles for my personal runs in my ~/ovs-logfiles directory:
+    ovs_vswitchd_log=~/.ovs-logfiles/vswitchd.log
+
+

+
+
+-------------------------------------------------------------------------------
+TODO
+-------------------------------------------------------------------------------
+
+1. Better documentation. 
+2. Option for automatic downloading, configuration, and installation of OVS. 
+3. Symlinks or alias generation for selecting the correct ovs-* tools for
+   debugging the running configuration.
