This example demonstrates the use of a Glacier2 router and the
implementation of a Glacier2 session server.

To run the demo, first start the server:

$ python Server.py

In a separate window, start the session server:

$ python SessionServer.py

In a separate window, start the Glacier2 router:

$ glacier2router --Ice.Config=config.glacier2

In a separate window, start the client:

$ python Client.py

If you plan to run this demo using clients on different hosts than
the router, you must first modify the configuration. You need to
change the Glacier2.Client.Endpoints property in config.glacier2 and
the Ice.Default.Router and Callback.Client.Router properties in
config.client. In all cases you must replace the "-h 127.0.0.1"
parameter with the actual external address of the machine on which
glacier2router is running.
