"""Python Bindings for the GTK Widget Set.

PyGTK is a set of bindings for the GTK widget set. It provides an object 
oriented interface that is slightly higher level than the C one. It 
automatically does all the type casting and reference counting that you 
would have to do normally with the C API. You can find out more on the 
official homepage, http://www.daa.com.au/~james/pygtk/"""
