+ - **backward incompatible change**: if you are calling function to parse
+   command line, earlier you could write ``main()`` to accomplish that
+   task. This syntax is unavailable now (this will try to actually call a
+   function), and you should use ``main(argv=sys.argv[1:])``.
+ - if default value of an option is a fuction, always call it (None is passed in
+   case when option is not supplied)

 After that you can simply call this function as an entry point to your program::
 
   if __name__ == '__main__':
-      main()
+      main(argv=sys.argv[1:])
 
 This will run command line parsing facility, using arguments from
-``sys.argv``. ``%name`` will be replaced with ``sys.argv[0]`` (or prepended to
-usage string if there is no ``%name``), and rest of arguments will be passed to

 Of course, you can use your function programmatically, supplying list of
 arguments to function::
 
-  main('-l 0.0.0.0 /my/dir'.split())
+  main(argv='-l 0.0.0.0 /my/dir'.split())
 
 Or, if you need this, you can call this function as usual::
