+/**
+ * A class holding general data about the application and some methods for
+ * the management including the entry point.
+ *
+ * E.g.:
+ *
+ * index.php?app=my_app
+ *
+ * You need to create a folder in the folder "application" named "my_app"
+ * (without the quotes) and create a include file called
+ * class_ApplicationHelper.php. You have to write the same class for your
+ * application and implement the same interface called ManageableApplication
+ * because this class include file will be searched for.
+ *
+ * It is good when you avoid more GET parameters to keep URLs short and sweet.
+ * But sometimes you need some GET paramerers e.g. for your imprint or info page
+ * or other linked pages which you have to create and state some informations.
+ *
+ * Please remember that this include file is being loaded *before* the class
+ * loader is loading classes from "exceptions", "interfaces" and "main"!
