Example client

-> -> New release June 30th. See news
/*
 * A simple tutorial for Ayyi C clients.
 *
 * It demonstrates how to connect to a server, obtain and modify a Song object,
 * and how to be notified of remote model changes.
 * It runs in a shell, and outputs only debugging information, though changes
 * will be visible in other connected clients.
 *
 * For more advanced examples see the test/vala and model/test directories
