if you're going to post questions to arbitrarily chosen threads, you 
could at least change the subject (but it's a lot nicer to open a new 
thread).

the "**" prefix tells Python to stuff any excess keyword arguments into 
the given variable:

 >>> def func(**kwargs):
...     print kwargs
...
 >>> func()
{}
 >>> func(spam=1, egg=2)
{'egg': 2, 'spam': 1}

for more on Python's parameter syntax, see the section on "def" in the 
language reference; see e.g.
