[pygtk] Couple of easy questions

[Micah Carrick]

I'm an experienced GTK+ developer using C, however, I'm dinking around 
with Python for a new tutorial I'm writing. Took me all of 2 minutes to 
figure out how to get my glade file up and properly terminating. :)

Couple of questions...

1. When using gtk.Builder (or glade), in C we use g_object_unref() on 
the builder object to free memory when we've moved references to the 
widgets we need into variables (don't need the XML sitting around). 
Obviously python will handle memory for me, however, do I need to set 
the variable to None or something so it knows I'm done with it?

Example:

self.builder = gtk.Builder()
self.builder.add_from_file("ui.xml")
self.window = self.builder.get_object("window")
dic = { "on_window_destroy" : gtk.main_quit }     
self.builder.connect_signals(dic)
# I'm done with the builder... is it cleaned up automatically?

2. What's the difference between importing pygtk and just gtk? Is that a 
distribution difference? Just 'import gtk' works for me... but I need 
this code to be nice and universal.

3. I was looking at some PyGTK projects and noticed some have everything 
all in one .py file. Is it common convention to put everything into a 
single file, put each class into it's own file, or does it vary from 
programmer to programmer?
