+OpenFlow test framework top level script
+
+This script is the entry point for running OpenFlow tests
+using the OFT framework.
+
+The global configuration is passed around in a dictionary
+generally called config.  The keys have the following
+significance.
+
+<pre>
+    platform          : String identifying the target platform
+    controller_host   : Host on which test controller is running (for sockets)
+    controller_port   : Port on which test controller listens for switch cxn
+    test_dir          : (TBD) Directory to search for test files (default .)
+    test_spec         : (TBD) Specification of test(s) to run
+    log_file          : Filename for test logging
+    list              : Boolean:  List all tests and exit
+    debug             : String giving debug level (info, warning, error...)
+</pre>
+
+See config_defaults below for the default values.
+
+The following are stored in the config dictionary, but are not currently
+configurable through the command line.
+
+<pre>
+    dbg_level         : logging module value of debug level
+    port_map          : Map of dataplane OpenFlow port to OS interface names
+    test_mod_map      : Dictionary indexed by module names and whose value
+                        is the module reference
+    all_tests         : Dictionary indexed by module reference and whose
+                        value is a list of functions in that module
+</pre>
+
+Each test may be assigned a priority by setting test_prio["TestName"] in 
+the respective module.  For now, the only use of this is to avoid 
+automatic inclusion of tests into the default list.  This is done by
+setting the test_prio value less than 0.  Eventually we may add ordering
+of test execution by test priority.
+
+To add a test to the system, either: edit an existing test case file (like
+basic.py) to add a test class which inherits from unittest.TestCase (directly
+or indirectly); or add a new file which includes a function definition 
+test_set_init(config).  Preferably the file is in the same directory as existing
+tests, though you can specify the directory on the command line.  The file
+should not be called "all" as that's reserved for the test-spec.
+
+If you add a new file, the test_set_init function should record the port
+map object from the configuration along with whatever other configuration 
+information it may need.
+
+TBD:  To add configuration to the system, first add an entry to config_default
+below.  If you want this to be a command line parameter, edit config_setup
+to add the option and default value to the parser.  Then edit config_get
+to make sure the option value gets copied into the configuration 
+structure (which then gets passed to everyone else).
+
+By convention, oft attempts to import the contents of a file by the 
+name of $platform.py into the local namespace.  
+
+IMPORTANT: That file should define a function platform_config_update which
+takes a configuration dictionary as an argument and updates it for the
+current run.  In particular, it should set up config["port_map"] with
+the proper map from OF port numbers to OF interface names.
+
+You can add your own platform, say gp104, by adding a file gp104.py to the
+platforms directory that defines the function platform_config_update and then
+use the parameter --platform=gp104 on the command line. You can also use the
+--platform-dir option to change which directory is searched.
+
+The current model for test sets is basic.py.  The current convention is
+that the test set should implement a function test_set_init which takes
+an oft configuration dictionary and returns a unittest.TestSuite object.
+Future test sets should do the same thing.
+
+Default setup:
+
+The default setup runs locally using veth pairs.  To exercise this, 
+checkout and build an openflow userspace datapath.  Then start it on 
+the local host:
+<pre>
+  sudo ~/openflow/regress/bin/veth_setup.pl 
+  sudo ofdatapath -i veth0,veth2,veth4,veth6 punix:/tmp/ofd &
+  sudo ofprotocol unix:/tmp/ofd tcp:127.0.0.1 --fail=closed --max-backoff=1 &
+
+Next, run oft: 
+  sudo ./oft --debug=info
+</pre>
+
+Examine oft.log if things don't work.
+
+@todo Support per-component debug levels (esp controller vs dataplane)
+
+Current test case setup:
+    Files in the tests direcoty that contain a function test_set_init are
+considered test files.
+    The function test_set_init examines the test_spec config variable
+and generates a suite of tests.
+    Support a command line option --test_mod so that all tests in that
+module will be run.
+    Support all to specify all tests from the module.
