This demo is a minimal Ice "hello world" application. Each time the client is run a "sayHello" invocation is sent to the server.
The Ice extension for Ruby currently supports only client-side functionality, therefore you must use a server from any other language mapping.
After starting the server, run the Ruby client:
$ ruby Client.rb
Note that this demo hardwires port 10000. If port 10000 is not available on your machine, you need to edit both client and server to use a free port.
