+/**
+ * Omnipay class
+ *
+ * Provides static access to the gateway factory methods.  This is the
+ * recommended route for creation and establishment of payment gateway
+ * objects via the standard GatewayFactory.
+ *
+ * Example:
+ *
+ * <code>
+ *   // Create a gateway for the PayPal ExpressGateway
+ *   // (routes to GatewayFactory::create)
+ *   $gateway = Omnipay::create('ExpressGateway');
+ *
+ *   // Initialise the gateway
+ *   $gateway->initialize(...);
+ *
+ *   // Get the gateway parameters.
+ *   $parameters = $gateway->getParameters();
+ *
+ *   // Create a credit card object
+ *   $card = new CreditCard(...);
+ *
+ *   // Do an authorisation transaction on the gateway
+ *   if ($gateway->supportsAuthorize()) {
+ *       $gateway->authorize(...);
+ *   } else {
+ *       throw new \Exception('Gateway does not support authorize()');
+ *   }
+ * </code>
+ *
+ * For further code examples see the *omnipay-example* repository on github.
