+OpenFlow Test Framework
+
+Configuration fragment
+
+This file contains Python code to specify the configuration
+of the system under test.
+
+This is a work in progress.  The code below is for illustration only.
+
+The configuration information is extensible in that any 
+Python code may be added to this file (or its imports) and will 
+be available to test cases.  
+
+A platform identifier is given at the top of the file and most
+other information is determined by testing this value.  Additional
+files may also be imported based on the platform.
+
+The configuration must specify a mapping from system interfaces
+available to the test framework to OpenFlow port numbers on the
+switch under test.  This is done in the interface_ofport_map
+dictionary.  Future extensions may include specifying a driver
+for the port (so as to allow remote packet generation) and to
+specify a switch instance (to allow multiple switches to be
+tested together).
+
+Currently, the assumption is that ports are bidirectional, so
+specifying "OF port 1 is connnected to eth2" implies this is so
+for both TX and RX.

+##@var platform
+# A string representing the platform under test.  Tested below
+# for determining other variables.
+
+##@var switch_cxn_type
+# How does the test framework communicate to the switch?
+#
+# Options include:
+# @arg localhost:   Switch is running on same host as tests
+# @arg ssh:         Use paramiko to control ssh connection. Needs switch
+# IP and other params
+#
+# For ssh, additional variables include
+# @arg switch_ip = "192.168.2.21"
+# @arg switch_username = "root"
+# @arg switch_password
+
+##@var switch_init
+# A function to be called to initialize the switch.  May be None
+# to indicate no such function needs to be called.
+
+##@var switch_connect
+# Function to be called to prompt the switch to connect to the
+# controller.  The function may need to maintain connection state 
+# as it could be called multiple times between disconnects.
+
+##@var switch_disconnect
+# Function to be called to force the switch to disconnect from the
+# controller. 
+
+##@var controller_ip
+# Gives the controller IP address to use
+
+##@var controller_port
+# Gives the controller port to use
