Orun (Object RUNtime) is a small/lightweight library that provides a fast
to build Python RIA, the client communicates with the server through ajax.
Typical usage often looks like this::

    #!/usr/bin/env python
    # Cherrypy + ExtJS example

	from orun.extjs import *
	from orun.extjs import cp

	def ok_click(id, *args, **kwargs):
	    cli << Ext.getCmp(id).setText('Clicked')
	    cli << js.client.alert('Server side message')

	def button_click(id, *args, **kwargs):
	    js.write("""
	    Ext.getCmp("%s").setText('Clicked');
	    alert('Server side callback message');
	    """ % id)

	class MyApplication(cp.ExtApplication):
	    def main(self, *args, **kwargs):
	        wnd = Ext.create('widget.window', {'title': 'My Window', 'width': 300, 'height': 250,
	            'items': [{'xtype': 'button', 'text': 'Click Here', 'handler': button_click}],
	            'buttons': [
	                {'text': 'OK', 'handler': ok_click},
	                {'text': 'Close', 'handler': js.function('this.up("window").close();')}]})
	        wnd.show()
	        wnd.setHeight(200)

	app = MyApplication('Orun (ExtJS Application)')
	app.run()

The example above, runs cherrypy application on 8080 http port, and exposes
extjs method.
