# This is an example of using dynamic trees (trees where nodes are only
# calculated as they are needed) with pygtk. This particular example
# allows for the browsing of the variables in a module, allowing the
# descent into classes and modules and other objects with a __dict__
# attribute.
# If this file is run straight, it will let you browse the gtk module.
