+ * The VM is configured to automatically run this class, and to call the

+ * documentation. If you change the name of this class or the package after
+ * creating this project, you must also update the manifest file in the resource
+ * directory.
+ *
+ * WARNING: While it may look like a good choice to use for your code if you're inexperienced,
+ * don't. Unless you know what you are doing, complex code will be much more difficult under
+ * this system. Use IterativeRobot or Command-Based instead if you're new.
