// 1. Ensure you are loading the following libraries:
//    > jQuery
//    > JSJaC (or any other supported XMPP library)
//    > Giggle.js

// 2. Define configuration generators
var single_config_generator = function() {
    // Return single configuration object
    // Refer to single_client.js source for more
    return {};
};

var muji_config_generator = function() {
    // Return muji configuration object
    // Refer to muji_client.js source for more
    return {};

// 3. Initiate the listener
// Note: here using 'JSJaCConsoleLogger' from JSJaC as a console wrapper
Giggle.listen({
    plug: GIGGLE_PLUG_JSJAC,
    connection: GIGGLE_CONNECTION,
    debug: (new JSJaCConsoleLogger(4)),
