+ *
+ * Usage example:
+ *
+ *   var foo = new $.JsonRpcClient({ ajaxUrl: '/backend/jsonrpc' });
+ *   foo.call(
+ *     'bar', [ 'A parameter', 'B parameter' ],
+ *     function(result) { alert('Foo bar answered: ' + result.my_answer); },
+ *     function(error)  { console.log('There was an error', error); }
+ *   );
+ *
+ * More examples are available in README.md

+ *   foo.call(
+ *     'bar', [ 'A parameter', 'B parameter' ],

+ * This plugin requires jquery.json.js to be available, or at least the methods $.toJSON and
+ * $.parseJSON.
+ *
+ * The plan is to make use of websockets if they are available, but work just as well with only
+ * http if not.
+ *
+ * Usage example:
+ *
+ *   var foo = new $.JsonRpcClient({ ajaxUrl: '/backend/jsonrpc' });
+ *   foo.call(
+ *     'bar', [ 'A parameter', 'B parameter' ],
+ *     function(result) { alert('Foo bar answered: ' + result.my_answer); },
+ *     function(error)  { console.log('There was an error', error); }
+ *   );
+ *
+ * More examples are available in README.md
