+/**
+ *
+ * Inject a snippet of JavaScript into the page for execution in the context of the currently selected
+ * frame. The executed script is assumed to be asynchronous and must signal that is done by invoking
+ * the provided callback, which is always provided as the final argument to the function. The value
+ * to this callback will be returned to the client.
+ *
+ * Asynchronous script commands may not span page loads. If an unload event is fired while waiting
+ * for a script result, an error should be returned to the client.
+ *
+ * The script argument defines the script to execute in the form of a function body. The function will
+ * be invoked with the provided args array and the values may be accessed via the arguments object
+ * in the order specified. The final argument will always be a callback function that must be invoked
+ * to signal that the script has finished.
+ *
+ * Arguments may be any JSON-primitive, array, or JSON object. JSON objects that define a WebElement
+ * reference will be converted to the corresponding DOM element. Likewise, any WebElements in the script
+ * result will be returned to the client as WebElement JSON objects.
+ *
