Interactive Python interpreter to play with GTK+ without blocking the console

pygigtk.py

#!/usr/bin/python3
"""An interactive Python interpreter to play with GTK+ without blocking the console

Usage:
./pygigtk.py

You don't need to call 'Gtk.main' in the console, just start using Gtk, such as
creating a window and 'show_all' it. Gtk, GObject, etc have been imported.
